The command aims to align the ends of the X gantry (for a Prลฏลกa i3-style printer). See the video demonstration below. Using the given current, Marlin will move the Z axis (at homing speed) to the top plus a given extra distance. Since this intentionally stalls the Z steppers, you should use the minimum current required to move the axis.

Basically: Install VScode, and add the platformio plugin in it. Download marlin source from GitHub and unzip. Also download configuration examples. Copy configuration.h and configuration_adv.h from the ender 3 pro example folder into the Marlin folder that you unzipped. In VScode, open the unzipped folder.

When the X-endstop is not inverted, homing only makes the axis progress a bit, similar to what @emartinez167 ran into Thank you @thinkyhead the Viki worked great in the older version of Marlin 1.0.2-1. Marlin 1.0.2-1 - X-Axis had weird X-endstop behavior but viki worked So you might want to move that stepper motor to your Z axis, or

Based on your pictures, Y_MIN should be -39, Y bed size is correct, and Y_MAX should be similar to the X_MAX where you subtract Y_MIN from Y_BED_SIZE. Assuming your printer has the ability to travel to all of these extremes, of course. E:Just read your comment about the edge of the Y axis not reachable by the nozzle.

Raise Z up a little bit on the first layer: M206 Z-0.2. Shift the print area 10mm to the left: M206 X10. Use M206 to apply a persistent offset to the native home position and coordinate space. This effectively shifts the coordinate space in the negative direction. See examples below.

Disabled #define Z_DUAL_ENDSTOPS -> OK ( up and down possible, but this is needed, printer has 2 endstops and 2 stepper for Z) checked the endstops with M119. -> they are OK checked the endstops with M43 E0 -> they are OK. is the z axis moved downwards after homing the steppers are not spinning but the position is decremented on the display
Unlikely but maybe. You could try superglueing them down lol. Press the auto home button. Click move and move the z axis to 0. Go to the z axis offset and put in your value. I think mine was -1.50. Save the configuration. Print stuff. My main problem is that in my guide that I follow I haven't even made it to the step where I adjust z offset.

Bgnome โ€ข 4 yr. ago. The BLTouch should not retract on a homing move. It should do a self test on a boot. It is possible that the magnet in the BLTouch is too close to the set screw, causing an automatic retraction. With the pin retracted, try backing out the set screw until the pin drops, then tighten it a bit so that the pin won't drop on it

Its still not working correctly though, I can home correctly and everything works as normal, After homing I move to Z0 and issue the G38.3 Z50 command, the axis starts to move up but does not stop when triggering the Z_MIN endstop, it only responds to the Z_MAX endstop (which is the home switch its moving towards) I want to be able to stop the
