Will try again to verify. I don't have another type of printer besides Delta but from what I hear homing is kind of...opposite on other types I'm not sure I fully understand it yet until I build one. I will go into as much detail as possible but please keep in mind that marlin is constantly being developed and changes can lead to a setting being named differently, a file being renamed and so on. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). // - Prevent Z homing when the Z probe is outside bed area. Help needed : Marlin z axis homing speed settings. With a retract of just 2mm this takes 10 seconds. im debugging now Help needed : Marlin z axis homing speed settings. slower (half speed) decent until stop hit again. | Many commercial 3D printers come with Marlin installed. I fear that I may have not zero'd down enough, so there will be a noticeable gap/weak spot, but I won't know that until I get more layers on than there are at this moment. Homing is required before G29, M48, and some other procedures.. I don't know what it means specifically by "homing_feedrate_mm_m array instead". Zarquon. // #define Z_SAFE_HOMING But I will try changing the HOMING_FEEDRATE to see which of the steps is affected. Ok. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. // - If stepper drivers time out, it will need X and Y homing again before Z homing. G-code G29 has a speed parameter: S: Set the XY travel speed between probe points (in units/min) From below (TH3D firmware) can be seen that a value of 12000 mm/min will speed up and is generally safe to use. As a side-effect, X and Y homing are required before Z homing. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z. I then set Z at zero, G92 Z0. Only the first raise is painfully slow. And you set it so Z0 is appropriate nozzle height. Having a seam there isn't a problem. And a 11 foot tall delta? Was able to make it happen, though I fear that I may have misjudged exactly where zero was, but we'll see in a few hours. Apparently Marlin (or Octoprint? I recently upgraded my prusa i3 firmware to a newer version of marlin. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Making statements based on opinion; back them up with references or personal experience. NOTE: The latest Marlin 2.0 handles the boundaries automatically and the below code is not needed anymore for the latest Marlin 2.0 version. My main research advisor refuse to give me a letter (to help apply US physics program). // - Prevent Z homing when the Z probe is outside bed area. Marlin config was not changed: //// MOVEMENT SETTINGS #define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E #define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0} // set the hom . Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. As a side-effect, X and Y homing are required before Z homing. The text was updated successfully, but these errors were encountered: Check out HOMING_FEEDRATE in Configuration.h and in Configuration_adv.h. Are you sure? feedrate for line_to_destination is feedrate/60. This is the moving speed of the axis when homing in [mm/min]. Home > Firmware Folder > Firmware - Marlin > … https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1953, https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1820. Now the printer seems to be of two minds when it comes to finding the origin. feedrate is needed in line_to_destination. Homing on the Ender 3 with HOMING_FEEDRATE_XY set to 50*60 was shown (MarlinFirmware#12074) to cause the end-stop micro-switches to bottom out, causing the carriage for both X and Y axis to physically crash into the micro switch. So, the PC freezes up and I have to pause the print and reboot. This prevents your Z homing from occuring without prior X and Y homing. idk) will let you print without homing Z as long as it knows where zero is. You signed in with another tab or window. - Increasing Z homing speed : fails too, in fact, the homeing speed in marlin is way faster of what I have tried with repetier - Loosing steps: I have seen motors loosing steps, but this is different, the motor gets stucked - reducing z-jerk: the original value is 0.3, I have lowered it to 0.2 and 0.1 . Using the given current, Marlin will move the Z axis (at homing speed) to the top plus a given extra distance. When I'm homed and my carriages are all at the top of the towers and clicks the endstops...I have my manually set home Z of 367.55 so the firmware knows it can travel down Z that far. What should I do. I then set Z at zero, G92 Z0. G28 disables bed leveling. Without this option enabled the nozzle will crash into the bed when homing. homing feed rate. I use Marlin/Ramps but, don’t use Estcam. Uncomment Z_SAFE_HOMING. I have just checked it and @Wurstnase is correct. We might get some questions why "Marlin homes slower than TH3D" Related Issues #12074 On my printer the Z-axis switch is over to the side of the frame holding the print bed, so I can home Z with the print head anywhere. Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch Beekeeper. look in same block for "feedrate = max_feedrate[Z_AXIS];" Re-homing Z: trouble resuming a print, what if I can't re-home? What is this about This post will give guidelines on how to flash your own marlin onto a Eryone Thinker S V2 (NOT the V1) or ER20 printer. G29 seems to somewhat randomly leave the z-probe down after the last probe. 4mm/s / 20 = 0.2mm/s. why not in line 1820 it's not the problem // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. I've been trying to fix an issue with my Y homing function for quite some time. When I run G28 with no arguments, homing speeds are as expected. I'm using the Marlin firmware (1.1.0-RC7 - 31 July 2016) for a 3d printer. It only takes a minute to sign up. Sign in Are those Jesus' half brothers mentioned in Acts 1:14? It's actually a vanilla Kubuntu 18 PC whose only function is to manage the printer. Homing issues with Marlin. That's interesting it must not be applying the same way for delta. Homing issues with Marlin March 20, 2012 06:47PM Registered: 9 years ago Posts: 16 Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. it is funny because this section is in a else Brackets so in a nut shell it's saying #define Z_SAFE_HOMING … // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Discussion. As the Creality printers use the same hardware across their models, this change can be applied to all models. I recently upgraded my prusa i3 firmware to a newer version of marlin. Without this, you may accidentally miss the bed when homing Z. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. lower the moving speed of the Z-axis motor, search for . Everything seems to be at the rate I expect except that initial rise. In Marlin firmware I finally have working FW that properly compensates for the bed level, and homes within my lilfetime. This is the moving speed of the axis when homing in [mm/min]. After I changed my extruder, Please see: [forums.reprap.org] my Z axis homing speed drooped to almost 0. // - Prevent Z homing when the Z probe is outside bed area. to your account. All fails There is no differentiation between the x/y axis homing speed and the z axis speed. normal decent until stop hit Note that aesthetics aren't an issue: these are mechanical parts to all they need is to not snap in the middle. Running Marlin 1.1.2, printing from Octoprint on Linux PC. and i have 8 start leadscrews for Z and can move well over 40mm/s, found it code expects Max Z feed rate in MM per min Built latest Marlin (as of couple hours ago) for Printrboard on Simple Metal. // - If stepper drivers time out, it will need X and Y homing again before Z homing. edited code to call homing feedrate for Z axiz for more control I'm currently using Marlin firmware (1.1.0-RC7 - 31 July 2016) and would like to experiment with print speed. Homing feedrate The homing feedrate is the speed at which the axis home, by default it's set to #define HOMING_FEEDRATE {50*60, 50*60, 5*60, 0} // set the homing speeds (mm/min) Between the {} are the axis x,y,z,extruder, where extruder never needs homing. Check with your vendor if you need source code for your specific machine. https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1820? // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Notes. #define Z_CLEARANCE_BETWEEN_PROBES 3. Help needed : Marlin z axis homing speed settings. To know this would be helpful in setting up a piezo z probe. Homing feed rate. Then moved X10 Y0, a convenient place to work. I would sincerely appreciate any help. #define Z_CLEARANCE_DEPLOY_PROBE 5 . I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. #define HOMING_FEEDRATE {50*60, 50*60, 4*60} Axis steps per unit. I can't wrap my mind around what I need to do here. How far would we have to travel to make all of our familiar constellations unrecognisable? privacy statement. Is it possible for planetary rings to be perpendicular (or near perpendicular) to the planet's orbit around the host star? When this correction is correct in line 1953 https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1953 Notes. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". Steps per mm How to calculate charge analysis for a molecule. The PC should not freeze up, ever. #define Z_MIN_POS 0. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. Homing speeds are just below the Steps per Unit, I believe, but I don't have it in front of me. We’ll occasionally send you account related emails. Using DSolve to find y[x] for a second-order differential equation. // - Prevent Z homing when the Z probe is outside bed area. Steps per mm I understand that changing the 20 number up or down changes the homing feedrate but I would like to know what 20"60 means regarding the Z feed rate in mm/m. This command is deprecated. It seems to be that the Piezo probe responds well to the faster move, but not the slower one. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z. Welcome! When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it … #define Z_SAFE_HOMING. This video come from https://www.youtube.com/user/fiverats/featured It‘s said black marlin can swim more than 100-130km/h?? Log In Create A New Profile. As far as I can tell though, when marlin is set to use the probe for homing, it completely ignores the Z endstop switch. A command like G1 F1000 sets the feedrate for all subsequent moves. in config.h as it looks like the given speed is to high. With this change, the second probing speed for Z at G28 is the same as the first probing. if not delta do this Thank you TechMasterJoe! Without this, you may accidentally miss the bed when homing Z. painfully slow rise Set speed percentage factor, aka “Feed Rate” which applies to all G-code-based moves in all (X, Y, Z, and E) axes. There is no differentiation between the x/y axis homing speed and the z axis speed. Default for this setting puts the nozzle in the center of the bed for G28Z, but you can define a corner offset if you wish. @AnHardt Sure, sure! Use Z_STEPPER_AUTO_ALIGN instead. I use pronterface to do all my testing. Why do password requirements exist while limiting the upper character count? What are the earliest inventions to store and release energy (e.g. MathJax reference. This causes problems with many printers as their z-axis couldn't move that fast. Currently the printing is not perfect due to slight inaccuracies in movements along the x and y axis. Already on GitHub? normal speed rise In the file Marlin_main.cpp I see in the process_next_command() function, there is a I kept the heat on for the bed so the print wouldn't shrink and break loose. About Marlin The newly added function line_to_destination takes the feedrate in mm/min. If homing is needed the LCD will blink the X Y Z indicators. G28 Z0 ; Home Z. I believe that should accomplish what you're after. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I'm not quite sure what the means, though I think it has to do with the speed at which the nozzle will home and from what I've seen the speed I have it at is the default speed XY (20*60) and Z (4*60). OK. I already have tried changing Z max feedrate and Z homing feedrate without noticing any major change in z speed. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). Is there a way I can home Z without the head moving to center? Is your printer supposed to home at Z0 normally? So search and enable Z_SAFE_HOMING if using a BlTouch or probe. The reason I use Z-max for homing is so that when i issue a Home it will pull the spindle up off the work area, which is especially needed before homing XY – I have Marlin set to home to Z first, then XY. Apparently Marlin (or Octoprint? Well the issue I'm having now is that after flashing the firmware (Marlin Firmware 1.1.9) and attempting to home, the z axis limit switch is unresponsive. The sequence for homing Z by issuing G28 Z0 is: Under normal circumstances the switch will never be hit, only if the BLtouch fails for some reason. (BTW I use min limit switches for my XY also – ) I found that in Marlin the G30 command does EXACTLY what i wanted. i just built it as of the last 20mins for my i3 and can confirm the bug is real This causes problems with many printers as their z-axis couldn't move that fast. // - If stepper drivers time out, it will need X and Y homing again before Z homing. #define Z_PROBE_LOW_POINT -3. #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) #define MULTIPLE_PROBING 2. Use MathJax to format equations. You’ll need to calibrate this later. The rest of the steps for resuming a print (editing the G-Code and what-not) are readily available in a dozen or more tutorials, so I won't cover that here. X and Y work as they should. If stepper drivers time out, X and Y homing will be required again. Reducing the homing speed prevents the switches from bottoming out. Being a derivative fro Marlin firmware, the bed leveling speed in between probes can also be easily set in G-code. #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) #define MULTIPLE_PROBING 2. Can someone explain to me the line in marlin "#define HOMING_FEEDRATE_Z (20*60)" as it relates to changing the Z homing speed? Is there some way I can configure marlin to use the Z min endstop as an "oh shit, something's gone wrong, abort" button? The feedrate is in mm per minute. The stepper motor receives step by step moving command from the controller. I have just open an issue to discuss that: #1791. If I run G28 Z0, the extruder is raised at a snails pace, then lowered to the stop at expected speed, then raised and lowered to stop again at expected (slower) speed. G-code G29 has a speed parameter: S: Set the XY travel speed between probe points (in units/min) From below (TH3D firmware) can be seen that a value of 12000 mm/min will speed up and is generally safe to use. I'm trying to change the feedrate for speed along the xy axis whilst the printer is in operation to make sure the printer stops on time and prints accurately. // // With this feature enabled: // // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. This mess in speeds is pissing me off. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). mines been changed to {2,2,2} just for this test In my snapshot, the offending line was 1953 in Marlin_main.cpp. White neutral wire wirenutted to black hot. Being a derivative fro Marlin firmware, the bed leveling speed in between probes can also be easily set in G-code. Benefits Reduced chance of physical / endstop damage on Creality printers. Podcast 302: Programming in PowerPoint can teach you a few things, Useful things to check for when cleaning up posts, Problem with print bed height on Creality Ender 4, Z-Axis zero/home position is higher than the actual print starting position, AnyCubic D (aka Predator) - Z-zeroing and first layer issues, Homing X and Y after stopping print through display. When I run G28 with no arguments, homing speeds are as expected. I propose we get rid of any mm/min functions, converting all to mm/s.. and just convert the gcodes received in mm/min as soon as they are received. Reply Quote. Thats awesome. Discussion. I would sincerely appreciate any help. Discussion. the speed problem only effects Z_RAISE_BEFORE_HOMING It travels up to the endstops horribly slow. @Wurstnase Can an exiting US president curtail access to Air Force One from the new president? idk) will let you print without homing Z as long as it knows where zero is. This will be performed before any bed levelling procedure; Using Auto Bed leveling¶ Refer to Marlin's excellent Wiki on the subject. Hello, I changed the version from 1.1.8 to 1.1.9. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. It's a 36 hour print with 11 hours left to go and I'd rather not start over. With the plate lowered and the print well out of harm's way, I homed X and Y. Realistic task for teaching bit operations. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Oftentimes in Marlin, speed or acceleration are expressed in [mm/s] or [mm/s2] but the feed is expressed in [mm/min]. This is the first time it's ever frozen mid-print and I think it's because I left Cura and several other Chrome tabs open. I notice that Z bump divisor is usually twice as much as X and Y on other setup's configs. Set speed percentage factor, aka “Feed Rate” which applies to all G-code-based moves in all (X, Y, Z, and E) axes. Without this, you may accidentally miss the bed when homing Z. Thanks for contributing an answer to 3D Printing Stack Exchange! Why can't I move files from my Ubuntu desktop to other folders? - Increasing Z homing speed : fails too, in fact, the homeing speed in marlin is way faster of what I have tried with repetier - Loosing steps: I have seen motors loosing steps, but this is different, the motor gets stucked - reducing z-jerk: the original value is 0.3, I have lowered it to 0.2 and 0.1 . // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // - Prevent Z homing when the Z probe is outside bed area. Have a question about this project? Or make it go the same speed as the initial tap? - MarlinFirmware/Marlin They're just all the same on mine because of the way deltas work. fly wheels)? Follow-up: yep, left too much room. Course Z is done much differently in a moving bed setup. How can i disable the second tap? How to pull back an email that has already been sent? I have the X, Y, and Z coords of where I need to begin again, and I've deleted all the GCode to that point. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Set the max feedrate for one or more axes (in current units-per-second). I've been trying to fix an issue with my Y homing function for quite some time. From a clean fir Why is this a correct sentence: "Iūlius nōn sōlus, sed cum magnā familiā habitat"? #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z // Feedrate (mm/m) for the "accurate" probe of each point #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) // The number of probes to perform at each point. Since this intentionally stalls the Z steppers, you should use the minimum current required to move the axis. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. Notes. In the several tutorials I read on how to resume a print, they all assume that the printer - which in my case had a restart of its own - knows where Z is. #define Z… Homing feed rate. Anyway, for those who may come along later, here's what I figured out: I already knew what my X, Y, and Z positions should be. By convention, most G-code generators use G0 for non-extrusion movements (those without the E axis) and G1 for moves that include extrusion. Report the current speed percentage factor if no parameter is specified. Movement settings Define the number of axis. I uploaded a ... Z homing issue after Marlin firmware update January 14, 2014 09:08AM Registered: 7 years ago Posts: 553 There may be homing acceleration in Adv_config.h, I dont quite remember but I know there were a few different settings located there.

Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Helllz ya hehe. I shaved off the new layers (having a kiridashi really helped there) and re-zero'd, but this time, after doing so I entered my initial Z value so that the nozzle touched the model and adjusted from there. Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. This prevents your Z homing from occuring without prior X and Y homing. I recently upgraded my prusa i3 firmware to a newer version of marlin. Without this option enabled the nozzle will crash into the bed when homing. still has another bug hiding 3rd print it started Z down on G29 tell it crashed so more then a few problems to be found so back to my 3-15-15 Dev dump that just works i got 117 parts to print i will do more debugging tomorrow almost done with my 11 foot tall delta. If homing is needed the LCD will blink the X Y Z indicators. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Uncomment Z_SAFE_HOMING. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). #define NUM_AXIS 4.
