Must have been I made some mistake in the previous steps, don't know how, but tried it again with M119 (making sure the + goes down and - goes up) it turns out that no the Zmax endstop is always triggered, no matter if something is put in the optosensor or notby kreatorp - Firmware - Marlin
Okay This is how it went : Checked the directions + and -, they where inverted (Z+ did not move the bed down but up) so changed the INVERT Z DIR to true. Then I checked the M119. I put a small screwdriver in the optosensor and checked the M119, Zmax was triggered. When nothing was in the optosensor, the M119 said Zmax is open.by kreatorp - Firmware - Marlin
I did that and it is going in the wrong direction. Maybe some option needs to be commented? For example I'm not using probe but maybe this needs to be uncommented? /** * Enable this option for a probe connected to the Z-MIN pin. * The probe replaces the Z-MIN endstop and is used for Z homing. * (Automatically enables USE_PROBE_FOR_Z_HOMING.) */ #define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN Andby kreatorp - Firmware - Marlin
I tried that, changed to min and -1 but it goes into opposite direction, it goes down; not up when homing; I changed the Z endstop to MAX back and it is going in the right direction now, but still won't trigger the endstop; I found somewhere that changing #define HOMING_BUMP_MM { 10, 10, 10 } in the configuration_adv.h file would do the trick but I don't know to which value to change, because Iby kreatorp - Firmware - Marlin
Hi, Thank you for allowing me access to this group; I need help in resolving a Z axis endstop settings. I’m building a custom 3d printer and using marlin firmware, main board is BTT SKR 1.4 Turbo, optical endstops blasini on all three axes. Bed is moving from top to bottom. Here is the picture explaining where I put the locations of endstops, and where is my desired home for all three axes. The Xby kreatorp - Firmware - Marlin
