marlin disable z homing

Homing feed rate. 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. Level your X axis by trying to move the Z axis past its physical limit. This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. to your account. Posted by. This appears to have worked because i now get two taps at the same speed. 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. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. ... (By default Marlin assumes the Z-Max endstop pin.) 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. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. Successfully merging a pull request may close this issue. The Anet A8 for one - the endstops are at X=-33 Y=-15 or so. Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. Without this, you may accidentally miss the bed when homing Z. I’m using an … Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. It is the total number of axis (3) plus the number of extruders (1). 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? Examples. Such is the case with G28 X Y or G28 Z. T… I would like to look at them as I am curious as to why they would do that. :x: BLTouch is NOT deployed while homing Z.:heavy_check_mark: BLTouch is not monitored while homing Z. **Actual behavior:**Won't compile, fatal error. I then set Z at zero, G92 Z0. Press question mark to learn the rest of the keyboard shortcuts. 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. 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). privacy statement. Effectively printer is unstoppable when homing Z and will smash to the bed. 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. Even without a good reason that would be true. Disable 'double tap' z homing on marlin. Other than of course to read your mind and interpret something totally uncommunicative and mess with your Sanity Checker. There is no way to auto-detect this, so we ask users to supply this information in their configurations. Notes. with it enabled and X Y set to 0 it compiles - still with the other errors. 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. Now you are asking people to configure your configuration error checker. Setting up Marlin is fiddly at the best of times. How do you read this line: You have to make a decision. E3D v6, and the 'Orion Module' Piezo probe from precision piezo. Archived. /r/3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing. If stepper drivers time out, X and Y homing will be required again. Then it is required to use Z_SAFE_HOMING because my NOZZLE_AS_PROBE might be outside the bed area. + #define DISABLE_INACTIVE_Z false // Set to false if the nozzle will fall down on your printed part when print has finished. 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). #define DISABLE_INACTIVE_E true: #define DEFAULT_MINIMUMFEEDRATE 0.0 // minimum feedrate It seems to move the same distance each time, but I don't know for sure. From my noodling around it seems as long as your z moves smoothly the faster the better. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. I activate the Z_SAFE_HOMING option. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. When compiling it WITH Z safe homing enabled, my BLtouch does not work. I don't know that it will work, but it has a fair chance of working. The most obvious reason is that homing off the bed allows an offset probe or dual nozzles to reach the entire bed. The "paper drag" method is perfect for determining the correct Z level. Having to revise your configurations every update certainly doesn’t help. So why do you make it a requirement? 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? idk) will let you print without homing Z as long as it knows where zero is. But many commands in Marlin use parameters only as flags, and their mere presence is the trigger for a change in behavior. 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. How can i disable the second tap? Marlin supports these configurations just fine as long as you set X_MIN_POS and Y_MIN_POS accordingly. #define NUM_AXIS 4. 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. Enable it or comment out this line to continue."" Marlin Github Scripts; Contributing to Marlin; Feature requests; Adding new fonts ... control Disable endstops and keep them enabled when not homing. This is where you define home direction. Printers do it. // 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. In every step/combination, all other relevant configuration defines are shown for clarity. 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. They really seem to like booping the bed with speed. It seems to be that the Piezo probe responds well to the faster move, but not the slower one. It probably would be better stated as a carriage mounted probe. Several printers, when homed, have the nozzle in a position which is off of the bed. 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. 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. Sign in So, I do not require Z_SAFE_HOMING. Hi. Right now I'm having issues making sensorless homing to work. Disable endstops. You signed in with another tab or window. Even with -64 sensitivity I can't make it to work. on a Homemade i3 clone. I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. * * - The simplest option is to use a free endstop connector. I also cannot compile my firmware because of this. 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. I found a solution to this problem. This is the moving speed of the axis when homing in [mm/min]. I could probably bump it up even more.
