If the machine gets out of step for any … Marlin 2.0.5.3; Square Wave Stepping (Beta Feature) * Create a 50/50 square wave step pulse optimal for stepper drivers. Since I’m homing to Z-max when G28 is executed by marlin it will home Z first (moving to the endstop, and setting Z to Z_MAX_POS (0 in my case). 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. Yes, they move in the correct direction manually, just not when homing. It goes and rests on the hardware end-stops and stops there eventually. // Homing Settings # define X_HOME_LOCATION 0 # define Y_HOME_LOCATION 0 // Steps per MM Settings # define MKS_X_STEPS 80 # define MKS_Y_STEPS 80 # define MKS_Z_STEPS 400 # define MKS_E0_STEPS 95 # define MKS_E1_STEPS 95 // Motor Direction Settings # define MKS_X_DIRECTION 0 # define MKS_Y_DIRECTION 0 # define MKS_Z_DIRECTION 0 # define … Flag. On the Y axis I have the direction moving correct in pronterface, but when I press home it moves about 1cm in the wrong direction and stops. Homing once in the middle and once somewhere will result in a different z-height. Exactly the homing process will still move to the homing position defined by the hardware end stops.

Now I've finally had time to look into this, since I knew it somehow existed, but wasn't sure how it worked: Use the M206 G-code command in Marlin, Sprinter, Smoothie, or RepRap Firmware to offset the 0,0,0 coordinate of your printbed relative to the endstops. Successfully merging a pull request may close this issue. asked Jul 14 '18 at 18:47. Is it possible to fix via the LCD or … #define Z_MIN_PROBE_REPEATABILITY_TEST. When looking at the … Locate the Max Z Length variable (It is likely a negative value since the machine is homing in the wrong direction) Change this value to 150 (this is an arbitrary value and will get changed when we perform a Z height calibration) Save the EEPROM; Now that the EEPROM has been updated with a usable Max Z Length value, you will need to preform a Z Height Calibration. :) A quick recap on creating your own functions: 1) Go to the top of Marlin_main.cpp, and find an unused M-code. If the position is known then exit without homing. That is used for printers (like deltas) that home to the max end switches. This issue is stale because it has been open 30 days with no activity. With Marlin 1.0.0 RC2 a negative value for z lifts(!) With Marlin firmware, this value can be saved to EEPROM using the M500 share | improve this question | follow | edited Oct 22 '20 at 13:48.

Why do we use approximate in the present and estimated in the past? In the procedure known as “homing,” each axis is moved towards one end until the endstop switch is triggered, at which point the machine knows that the axis is at the endstop (home) position. Where did all the old discussions on Google Groups actually come from? We see, this basically is the same suggested by @LarsPoetter, but it comes with the great advantage that it can be saved to EEPROM, hence you don't need to add it every time or into every different sliccer (if I understand it correctly, - I haven't yet tried it myself). to your account, Recently a power failure highlighted a problem with homing. The G-Codes then fix that, but on every move it will move to the critical position and then back again.
