A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. Disable 'double tap' z homing on marlin. SENSORLESS_HOMING: Set SENSORLESS_HOMING sensitivity. New comments cannot be posted and votes cannot be cast. Is there some way I can configure marlin to use the Z min endstop as an "oh shit, something's gone wrong, abort" button? This prevents your Z homing from occurring without prior X and Y homing. Basically you tell the Marlin firmware which end of the axis the end stop switch is located. 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 … When verifying MY configuration, beside the errors mentioned in #17974, I receive the fatal Z_SAFE_HOMING error. // 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. Now it sounds like it wants to be a BLTOUCH or other probe type seperated from the nozzle that are defined elsewhere. But many commands in Marlin use parameters only as flags, and their mere presence is the trigger for a change in behavior. Setting up Marlin is fiddly at the best of times. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. as Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. I don't have a dump area, therefore, my nozzle never will go off the bed. Discussion. 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. 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). I had this problem with my peizo as well. I have a nozzle probe/Z_endstop. My probe IS the nozzle, not something mounted on the carriage. As a side-effect, X and Y homing are required before Z homing. 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. 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). In every step/combination, all other relevant configuration defines are shown for clarity. "disable the check in SanityCheck.h."? 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). Usage M121 . Mine is a piezo that is activated by the nozzle touching the bed. You have to make a decision. 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. 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. Disable 'double tap' z homing on marlin. 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. The Anet A8 for one - the endstops are at X=-33 Y=-15 or so. 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. ... (By default Marlin assumes the Z-Max endstop pin.) Even with -64 sensitivity I can't make it to work. * * - The simplest option is to use a free endstop connector. **Actual behavior:**Won't compile, fatal error. * To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. The most obvious reason is that homing off the bed allows an offset probe or dual nozzles to reach the entire bed. 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. 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. Previously, FIX_MOUNTED_PROBE was a nozzle probe. They can be used for homing … I could probably bump it up even more. Thanks. 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. #define Z_MIN_POS 0. Notes. * Note the Z axis value on the display it should be something like -1.5 M851 Z … Discussion. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. 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. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. Marlin will then rehome Z axis and restore normal current setting. You can do better than that! Does that seem as absurd to you as it does to me? I use the waterott TMC2130s. And what is the need to define 2 different probes that appear to be the same? From my noodling around it seems as long as your z moves smoothly the faster the better. Sign in You do not need Z_SAFE_HOMING if you follow the instructions. G28 disables bed leveling. So it is telling me to do what I have already done. Its a Marlin/Ramps setup. Thanks to #7470, #define ENDSTOPS_ALWAYS_ON_DEFAULT is always uncommented (enabled). The text was updated successfully, but these errors were encountered: read the error Marlin Github Scripts; Contributing to Marlin; Feature requests; Adding new fonts ... control Disable endstops and keep them enabled when not homing. 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. T… Archived. Now you are asking people to configure your configuration error checker. Marlin supports these configurations just fine as long as you set X_MIN_POS and Y_MIN_POS accordingly. Effectively printer is unstoppable when homing Z and will smash to the bed. It probably would be better stated as a carriage mounted probe. Close. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. Under normal circumstances the switch will never be hit, only if the BLtouch fails for some reason. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. ... // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. I would like to look at them as I am curious as to why they would do that. Movement settings Define the number of axis. Notes. You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. Description. privacy statement. After this command endstops will be kept disabled when not homing. Homing is required before G29, M48, and some other procedures.. You signed in with another tab or window. I have tried several Marlin releases (including 2.0) and nothing, following all the steps and nothing. Have a question about this project? If I manually move the head so that the 0 position is in this small window the printer will c If stepper drivers time out, X and Y homing will be required again. // Comment the following line to disable PID and enable bang-bang. 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. 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. "Z_SAFE_HOMING is recommended when homing with a probe. Without this, you may accidentally miss the bed when homing 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. Homing feed rate. Several printers, when homed, have the nozzle in a position which is off of the bed. + #define DISABLE_INACTIVE_Z false // Set to false if the nozzle will fall down on your printed part when print has finished. Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. Right now I'm having issues making sensorless homing to work. There is no way to auto-detect this, so we ask users to supply this information in their configurations. So, I do not require Z_SAFE_HOMING. But on the slower second tap it does not trigger. 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. Looks like you're using new Reddit on an old browser. #define NUM_AXIS 4. @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. How can i disable the second tap? 2. 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. Press question mark to learn the rest of the keyboard shortcuts. I issue the command, and Z homes first to get out of the way. Level your X axis by trying to move the Z axis past its physical limit. E3D v6, and the 'Orion Module' Piezo probe from precision piezo. Look for a subsection of Z Probe Options called "section homing". Successfully merging a pull request may close this issue. I activate the Z_SAFE_HOMING option. Such is the case with G28 X Y or G28 Z. :x: BLTouch is NOT deployed while homing Z.:heavy_check_mark: BLTouch is not monitored while homing Z. Even without a good reason that would be true. If stepper drivers time out, X and Y homing will be required again. This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. Examples. This works well for me though and we have the same hardware. 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. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. with it enabled and X Y set to 0 it compiles - still with the other errors. "Enable it or comment out this line to continue." I found a solution to this problem. It seems to move the same distance each time, but I don't know for sure. either enable Z_SAFE_HOMING or disable the check in SanityCheck.h. 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. Printers do it. 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. 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. I’m not really sure why this is even being debated. This appears to have worked because i now get two taps at the same speed. 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. It is the total number of axis (3) plus the number of extruders (1). 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. Or make it go the same speed as the initial tap? By clicking “Sign up for GitHub”, you agree to our terms of service and As a side-effect, X and Y homing are required before Z homing. Enable it or comment out this line to continue."" Option 6 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. 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 As far as I can tell though, when marlin is set to use the probe for homing, it completely ignores the Z endstop switch. #define DISABLE_INACTIVE_E true: #define DEFAULT_MINIMUMFEEDRATE 0.0 // minimum feedrate I am currently running my homing_feedrate_Z at 10*60 for both taps. We’ll occasionally send you account related emails. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. How do you read this line: Apparently Marlin (or Octoprint? 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. Disable endstops. If homing is needed the LCD will blink the X Y Z indicators. on a Homemade i3 clone. The X and Y ones work just fine, the problem lies with the Z-homing. to your account. It probably would be better stated as a carriage mounted probe. What I … 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. But on the slower second tap it does not trigger. I don't know that it will work, but it has a fair chance of working. 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? But still, I will get an error for something I don't need. They really seem to like booping the bed with speed. 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. Getting Decent Results Now. 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? Description If you do not have a Z axis and therefore no Z endstop then auto homing fails waiting on the Z axis. 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. I then set Z at zero, G92 Z0. Then this error message is also confusing: Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. Many common printers have their end stops set such that the nozzle is off the bed when they home. I got the error because it is not enabled ==> commented out. It's just a matter of how they're put together. 2 years ago. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) I’m using an … Can you tell me which one do? Steps to Reproduce Build or purchase an XY plotter, with no Z axis. I also cannot compile my firmware because of this. If you want to invoke Z Safe Homing, you must use G28 or G28 X Y Z. thinkyhead closed this on Nov 15, 2017 Posted by. Hi. 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. 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. 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. So why do you make it a requirement? 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. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. When compiling it WITH Z safe homing enabled, my BLtouch does not work. This is where you define home direction. Enable it or comment out this line to continue." After you compile and flash it should do both taps at the same 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). Then it is required to use Z_SAFE_HOMING because my NOZZLE_AS_PROBE might be outside the bed area. Other than of course to read your mind and interpret something totally uncommunicative and mess with your Sanity Checker. So using Z_SAFE_HOMING and setting X/Y location for Z homing seems appropriate. -#define DISABLE_INACTIVE_Z true // Set to false if the nozzle will fall down on your printed part when print has finished. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? The "paper drag" method is perfect for determining the correct Z level. There might be a better way to do this, I'm not sure. #error "Z_SAFE_HOMING is recommended when homing with a probe. Already on GitHub?
