marlin disable z homing

:x: BLTouch is NOT deployed while homing Z.:heavy_check_mark: BLTouch is not monitored while homing Z. How can i disable the second tap? You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. New comments cannot be posted and votes cannot be cast. // Comment the following line to disable PID and enable bang-bang. Thanks. By clicking “Sign up for GitHub”, you agree to our terms of service and It seems to move the same distance each time, but I don't know for sure. I don't have a dump area, therefore, my nozzle never will go off the bed. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. Steps to Reproduce Build or purchase an XY plotter, with no Z axis. I don't know that it will work, but it has a fair chance of working. Look for a subsection of Z Probe Options called "section homing". Homing is required before G29, M48, and some other procedures.. Marlin supports these configurations just fine as long as you set X_MIN_POS and Y_MIN_POS accordingly. In every step/combination, all other relevant configuration defines are shown for clarity. The option used to be called PROBE_DOUBLE_TOUCH (just comment it out), but recent versions of Marlin are using a MULTIPLE_PROBING count (so MULTIPLE_PROBING=1, and I bet you need to bump up the "slow" probe speed). This appears to have worked because i now get two taps at the same speed. Effectively printer is unstoppable when homing Z and will smash to the bed. Looks like you're using new Reddit on an old browser. Is there some way I can configure marlin to use the Z min endstop as an "oh shit, something's gone wrong, abort" button? Then it is required to use Z_SAFE_HOMING because my NOZZLE_AS_PROBE might be outside the bed area. Getting Decent Results Now. I am currently running my homing_feedrate_Z at 10*60 for both taps. * To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. Disable 'double tap' z homing on marlin. After this command endstops will be kept disabled when not homing. 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. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. But still, I will get an error for something I don't need. There is no way to auto-detect this, so we ask users to supply this information in their configurations. Even with -64 sensitivity I can't make it to work. Option 6 I could probably bump it up even more. ... // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. I’m using an … Mine is a piezo that is activated by the nozzle touching the bed. Configuring Endstops on Ramps 1.4 With Marlin Firmware - @section Homing : This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands (G-codes). You have to make a decision. + #define DISABLE_INACTIVE_Z false // Set to false if the nozzle will fall down on your printed part when print has finished. Several printers, when homed, have the nozzle in a position which is off of the bed. * * - The simplest option is to use a free endstop connector. Can you tell me which one do? When compiling it WITH Z safe homing enabled, my BLtouch does not work. #define DISABLE_INACTIVE_E true: #define DEFAULT_MINIMUMFEEDRATE 0.0 // minimum feedrate I would like to look at them as I am curious as to why they would do that. Successfully merging a pull request may close this issue. Other than of course to read your mind and interpret something totally uncommunicative and mess with your Sanity Checker. idk) will let you print without homing Z as long as it knows where zero is. Having to revise your configurations every update certainly doesn’t help. Such is the case with G28 X Y or G28 Z. Posted by. Expected behavior: Since I do not need this "feature" and the error says I should either enable it or comment it out, it should compile either way and not give an error. G28 disables bed leveling. #define NUM_AXIS 4. It is not a major problem, you can change within the Marlin firmware and indicate that for Z- we are going to use the Z+, but you have to make unnecessary modifications. "disable the check in SanityCheck.h."? I then set Z at zero, G92 Z0. Already on GitHub? 2 years ago. So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. As a side-effect, X and Y homing are required before Z homing. You would do this by going into Configuration.h and moving these lines: #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with Z probe outside the bed area. #error "Z_SAFE_HOMING is recommended when homing with a probe. This works well for me though and we have the same hardware. Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. Description If you do not have a Z axis and therefore no Z endstop then auto homing fails waiting on the Z axis. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. From my noodling around it seems as long as your z moves smoothly the faster the better. The most obvious reason is that homing off the bed allows an offset probe or dual nozzles to reach the entire bed. -#define DISABLE_INACTIVE_Z true // Set to false if the nozzle will fall down on your printed part when print has finished. I got the error because it is not enabled ==> commented out. This prevents your Z homing from occurring without prior X and Y homing. It probably would be better stated as a carriage mounted probe. Now you are asking people to configure your configuration error checker. T… Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Back in the Marlin pre-1.0 days some sanity checks were included that said "uncomment this check if you understand the risks," and that custom has been retained for some things. I’m not really sure why this is even being debated. Right now I'm having issues making sensorless homing to work. It's just a matter of how they're put together. 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. Discussion. Setting up Marlin is fiddly at the best of times. 2. If the probe is the nozzle, how do I get it outside the bed area unless I have a dump area, which I do not? either enable Z_SAFE_HOMING or disable the check in SanityCheck.h. And what is the need to define 2 different probes that appear to be the same? Marlin 2.0 on the SKR 1.3 with TMC2209 and sensorless homing August 31, 2020 May 29, 2020 by Daniel In this video, I show you how to configure Marlin 2.0 for the SKR 1.3 mainboard with TMC2209 stepper drivers and sensorless homing. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Printers do it. You signed in with another tab or window. Close. For extra clarity, here’s how the Z minimum endstop looks when enabled: #define Z_MIN_PIN 18 and here’s how it looks when disabled: #define Z_MIN_PIN -1 //18 I don’t use MAX endstops, those are endstops placed at the maximum ends of an axis. After I followed a Step by Step tutorial for setting it up and double checked with another one, I connected everything and was ready to Test. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. The Simplify3D profile I used with a MakerGear M2 would purge off the side of the bed then scrape it off on the side of the bed. I issue the command, and Z homes first to get out of the way. If stepper drivers time out, X and Y homing will be required again. But on the slower second tap it does not trigger. Its a Marlin/Ramps setup. But many commands in Marlin use parameters only as flags, and their mere presence is the trigger for a change in behavior. This is where you define home direction. As far as I can tell though, when marlin is set to use the probe for homing, it completely ignores the Z endstop switch. I use the waterott TMC2130s. If stepper drivers time out, X and Y homing will be required again. So it is telling me to do what I have already done. Description. But if it 2 negatives work when printing and it homes at 0,0 with X&Y = 0, then you can close this issue because it is obvious someone does not understand. I had this problem with my peizo as well. Disable 'double tap' z homing on marlin. They can be used for homing … How do you read this line: Its max is 130, and it heads upwards at full tilt, but doesn't make it halfway before slowing for half a revolution and stopping. Have a question about this project? This is the moving speed of the axis when homing in [mm/min]. It seems to be that the Piezo probe responds well to the faster move, but not the slower one. I activate the Z_SAFE_HOMING option. Enable it or comment out this line to continue."" 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). Without this, you may accidentally miss the bed when homing Z. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). @ruggb your X/Y min could be outside of the bed and defaulting to (0,0) might be not relevant if you haven't set X/Y_MIN_POS properly, and Marlin can't guess that. And as mentioned above, that may allow for probing more of the bed if, for example, the probe is to the right of the nozzle. "Enable it or comment out this line to continue." Marlin will then rehome Z axis and restore normal current setting. The X and Y ones work just fine, the problem lies with the Z-homing. Once you leveled with the paper, you do not need to create an offset to account for the paper thickness, however, there are purists that do that. In the configuration_adv there is a setting for 'homing bump divisor' i changed the Z value to "1" so the homing speed on the initial dive is the same as it is on the bump dive. My probe IS the nozzle, not something mounted on the carriage. Enable it or comment out this line to continue." Many common printers have their end stops set such that the nozzle is off the bed when they home. Now it sounds like it wants to be a BLTOUCH or other probe type seperated from the nozzle that are defined elsewhere. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. So why do you make it a requirement? This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. Previously, FIX_MOUNTED_PROBE was a nozzle probe. Then this error message is also confusing: They really seem to like booping the bed with speed. ... (By default Marlin assumes the Z-Max endstop pin.) with it enabled and X Y set to 0 it compiles - still with the other errors. Hi. This is not :x: because of the reason described in Option 3 point 3.:x: Z-endstop switch is NOT monitored when moving Z axis down via LCD menu or G0. If I manually move the head so that the 0 position is in this small window the printer will c This is a no nonsense, simple guide (and note to self) to configuring Marlin 2.0 for the Ender 3/Pro with BLTouch ABL sensor. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. The text was updated successfully, but these errors were encountered: read the error Or make it go the same speed as the initial tap? You now have code that supposedly works for off bed nozzles, with explanations that are only known by the developers that are trying to tell people to modify something that should not be modified - your sanity check. Discussion. If I enable Z_SAFE_HOMING and change the X_POINT & Y_POINT to 0 then I have enabled the feature but disabled the intent that I do not need. privacy statement. But on the slower second tap it does not trigger. All 4 files are also in the attached Base config (Z-endstop only, no BLTouch, homing at X=0, Y=0).zip file, the configuration in them matches the config in Option 1. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Examples. After homing in z, the hardware z endstop is deactivated (unless you have set ENDSTOPS_ALWAYS_ON_DEFAULT in configuration_adv.h, which can be overridden by M120, M121), but to protect the hardware a software endstop is activated (which in turn can be overridden … After you compile and flash it should do both taps at the same speed. Level your X axis by trying to move the Z axis past its physical limit. If you want to invoke Z Safe Homing, you must use G28 or G28 X Y Z. thinkyhead closed this on Nov 15, 2017 The Anet A8 for one - the endstops are at X=-33 Y=-15 or so. Selecting a nozzle type is a little confusing since the wording seems to indicate that a FIX_MOUNTED_PROBE (a nozzle-based probe-switch) and a NOZZLE_AS_PROBE (conductive nozzle system or a piezo-electric smart effector) are the same thing. It is the total number of axis (3) plus the number of extruders (1). That doesn't resolve the issue that I do not need Z_SAFE_HOMING and the only way to get around it is to enable it and set X&Y to 0 thus disabling it. You can do better than that! // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR 1. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. This is a guide to using g-code command M206 to set the Z axis home offset in the Marlin Firmware, a guide to a method of adjusting the gap distance between the hot end nozzle and the build platform. to your account. **Actual behavior:**Won't compile, fatal error. Sign in What I did in marlin was comment out the slow probe speed in configuration.h so it looks like this: // Speed for the "accurate" probe of each point, //#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 1.5), After doing this, open marlin_main.cpp and search for Z_PROBE_SLOW and change the slow to FAST. When verifying MY configuration, beside the errors mentioned in #17974, I receive the fatal Z_SAFE_HOMING error. I also cannot compile my firmware because of this. Notes. on a Homemade i3 clone. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. We’ll occasionally send you account related emails. Notes. It probably would be better stated as a carriage mounted probe. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) Basically you tell the Marlin firmware which end of the axis the end stop switch is located. "Z_SAFE_HOMING is recommended when homing with a probe. So, I do not require Z_SAFE_HOMING. as Marlin Github Scripts; Contributing to Marlin; Feature requests; Adding new fonts ... control Disable endstops and keep them enabled when not homing. There might be a better way to do this, I'm not sure. Naturally you'll need to have your min endstops wired up or you'll have a machine crash when it tries looking for said min endstop. Apparently Marlin (or Octoprint? Even without a good reason that would be true. Archived. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. * Note the Z axis value on the display it should be something like -1.5 M851 Z … #define Z_MIN_POS 0. What I … Homing feed rate. From the display go to the Menu then Prepare/Move axis/0.1mm/Move Z Now move the Z axis slowly down until the nozzle is the right distance from the build plate (folded piece of paper or thin card). Anet E12 - Skr 1.4 Marlin 2.0.7.2 Upgrade - Anet Lcd wont work I recently bought myself an BTT Skr 1.4 mainboard with TMC2209 for my Anet E12 printer because my old mainboard broke. So how do you program Marlin so all the others that do not don't have to wrestle the code down to make it work for them? Press question mark to learn the rest of the keyboard shortcuts. As a side-effect, X and Y homing are required before Z homing. If homing is needed the LCD will blink the X Y Z indicators. I have a nozzle probe/Z_endstop. Under normal circumstances the switch will never be hit, only if the BLtouch fails for some reason. E3D v6, and the 'Orion Module' Piezo probe from precision piezo. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. Movement settings Define the number of axis. The "paper drag" method is perfect for determining the correct Z level. My Z axis the only axis that has a stallguard capable stepper driver, so I need to find a way to disable sensorless homing on X and Y. I am trying to get sensorless probing to work, so I can't cut the DIAG1 pin and just use a mechanical endstop. It is common for X and Y axis to home the hot end to the Zero location and Z axis end stop home to the maximum positive location. Does that seem as absurd to you as it does to me? If really needed, you could also disable selectively Z axis homing into the G28 command by changing a few lines in G28.cpp (but not absolutely trivial) 1 Like sch00f (Raphael) November 23, 2019, 10:12am #8 I think I found it Disable endstops. I found a solution to this problem. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. Usage M121 .
