marlin disable z homing

Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. #define NUM_AXIS 4. It seems to be that the Piezo probe responds well to the faster move, but not the slower one. My probe IS the nozzle, not something mounted on the carriage. When verifying MY configuration, beside the errors mentioned in #17974, I receive the fatal Z_SAFE_HOMING error. 2. I got the error because it is not enabled ==> commented out. I use the waterott TMC2130s. "Enable it or comment out this line to continue." 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. 2 years ago. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. It probably would be better stated as a carriage mounted probe. This is where you define home direction.

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. 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. Notes. What I … So, I do not require Z_SAFE_HOMING. 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 … Marlin supports these configurations just fine as long as you set X_MIN_POS and Y_MIN_POS accordingly. Disable 'double tap' z homing on marlin. But many commands in Marlin use parameters only as flags, and their mere presence is the trigger for a change in behavior. 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. If stepper drivers time out, X and Y homing will be required again. I’m using an … Getting Decent Results Now. If I manually move the head so that the 0 position is in this small window the printer will c Homing feed rate. I have a nozzle probe/Z_endstop. If stepper drivers time out, X and Y homing will be required again. The X and Y ones work just fine, the problem lies with the Z-homing. This works well for me though and we have the same hardware. Steps to Reproduce Build or purchase an XY plotter, with no Z axis. #error "Z_SAFE_HOMING is recommended when homing with a probe. Such is the case with G28 X Y or G28 Z. 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. @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. This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. They really seem to like booping the bed with speed. Setting up Marlin is fiddly at the best of times. Examples. Successfully merging a pull request may close this issue. 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. 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). The Anet A8 for one - the endstops are at X=-33 Y=-15 or so. Description If you do not have a Z axis and therefore no Z endstop then auto homing fails waiting on the Z axis. "disable the check in SanityCheck.h."? I issue the command, and Z homes first to get out of the way. Hi. Movement settings Define the number of axis. Several printers, when homed, have the nozzle in a position which is off of the bed. Enable it or comment out this line to continue."" You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. Marlin will then rehome Z axis and restore normal current setting. Homing is required before G29, M48, and some other procedures.. #define Z_MIN_POS 0. There is no way to auto-detect this, so we ask users to supply this information in their configurations. But on the slower second tap it does not trigger. I then set Z at zero, G92 Z0. In every step/combination, all other relevant configuration defines are shown for clarity. As a side-effect, X and Y homing are required before Z homing. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. either enable Z_SAFE_HOMING or disable the check in SanityCheck.h. Mine is a piezo that is activated by the nozzle touching the bed. 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). Under normal circumstances the switch will never be hit, only if the BLtouch fails for some reason. Apparently Marlin (or Octoprint? I am currently running my homing_feedrate_Z at 10*60 for both taps. If homing is needed the LCD will blink the X Y Z indicators. This appears to have worked because i now get two taps at the same speed. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. 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. to your account. Sign in Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. But still, I will get an error for something I don't need. Having to revise your configurations every update certainly doesn’t help. Discussion. Close. Even without a good reason that would be true. Looks like you're using new Reddit on an old browser. Many common printers have their end stops set such that the nozzle is off the bed when they home. Without this, you may accidentally miss the bed when homing Z. I could probably bump it up even more. So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) Effectively printer is unstoppable when homing Z and will smash to the bed. 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. Disable endstops. 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. as 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? I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. privacy statement. This is the moving speed of the axis when homing in [mm/min]. How can i disable the second tap? I would like to look at them as I am curious as to why they would do that. // Comment the following line to disable PID and enable bang-bang. T… When compiling it WITH Z safe homing enabled, my BLtouch does not work. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. Thanks. New comments cannot be posted and votes cannot be cast. 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. 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. It is the total number of axis (3) plus the number of extruders (1). SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. Previously, FIX_MOUNTED_PROBE was a nozzle probe. I don't know that it will work, but it has a fair chance of working. + #define DISABLE_INACTIVE_Z false // Set to false if the nozzle will fall down on your printed part when print has finished. The text was updated successfully, but these errors were encountered: read the error idk) will let you print without homing Z as long as it knows where zero is. Then this error message is also confusing: 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! 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. Its a Marlin/Ramps setup. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. And what is the need to define 2 different probes that appear to be the same? Printers do it. 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. You have to make a decision. 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. I found a solution to this problem. Can you tell me which one do? 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. 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. We’ll occasionally send you account related emails. Description. 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? Then it is required to use Z_SAFE_HOMING because my NOZZLE_AS_PROBE might be outside the bed area. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. **Actual behavior:**Won't compile, fatal error. You signed in with another tab or window. 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. 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. on a Homemade i3 clone. So it is telling me to do what I have already done. * To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. So why do you make it a requirement? 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. Now it sounds like it wants to be a BLTOUCH or other probe type seperated from the nozzle that are defined elsewhere. Have a question about this project? "Z_SAFE_HOMING is recommended when homing with a probe. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. You do not need Z_SAFE_HOMING if you follow the instructions. There might be a better way to do this, I'm not sure. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. Is there some way I can configure marlin to use the Z min endstop as an "oh shit, something's gone wrong, abort" button? 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. 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. But on the slower second tap it does not trigger. Does that seem as absurd to you as it does to me? :x: BLTouch is NOT deployed while homing Z.:heavy_check_mark: BLTouch is not monitored while homing Z. Notes. Press question mark to learn the rest of the keyboard shortcuts. * * - The simplest option is to use a free endstop connector. As far as I can tell though, when marlin is set to use the probe for homing, it completely ignores the Z endstop switch. It seems to move the same distance each time, but I don't know for sure. E3D v6, and the 'Orion Module' Piezo probe from precision piezo. -#define DISABLE_INACTIVE_Z true // Set to false if the nozzle will fall down on your printed part when print has finished. G28 disables bed leveling. ... (By default Marlin assumes the Z-Max endstop pin.) The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. 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. Archived. Right now I'm having issues making sensorless homing to work. 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. 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. Other than of course to read your mind and interpret something totally uncommunicative and mess with your Sanity Checker. I activate the Z_SAFE_HOMING option. 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 This prevents your Z homing from occurring without prior X and Y homing. Usage M121 . Posted by. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Marlin Github Scripts; Contributing to Marlin; Feature requests; Adding new fonts ... control Disable endstops and keep them enabled when not homing.
