I dont think the voltage should be a problem, as long as in general the probe is working. See attached files for referenceby LaKi - Firmware - Marlin
Pin files are found under Marlin -> src -> pins -> your chip -> your board. I am not aware of any other changes I made to solve this. For some reason it wont let me attach my config files...by LaKi - Firmware - Marlin
Update: I got this issue fixed for me. As I am using sensorless homing with my board the diag pins for x and y are hardwired to x min and y min. For homing etc. this wasnt an issue as marlin seems to be able to recognize this. I solved this by changing the pins in the pinout file of my board (changed x/y+ to x/y-).. Now ABL gives repeatable results over pretty much the whole bed.by LaKi - Firmware - Marlin
Have you checked if #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR -1 need to be changed?by LaKi - Firmware - Marlin
Does anyone have an idea how to fix this? I seem to have to same problem with the "inverted" correction through ABL. Compensation seems to be reversed (compensate upwards where it should compensate downwards and vice versa). It looks like there are many ppl experiencing this problem. Part of it seems to be right handed / left handed coordinate system. I am printing on an Ender 5, with 0/0/0 inby LaKi - Firmware - Marlin
I connected both of them (X and Y) according to your instructions now. Now they are shown correctly as open when I check with M119. They wont be triggered when hitting the casing though. I tried sensitivity settings between 5 and 250, no change at all... Do you have an idea what I am missing? Nevermind. Mixed up X and Y when setting the jumpers. Everything is working now. Thank you very much Sby LaKi - Firmware - Marlin
Thanks for your fast response I removed the jumpers under the drivers, and testing via pronterface says communication to drivers is ok. Can you please confirm that this is the MKS TMC2209 layout? As far as I am aware Watterott changed the PIN-Layout for their TMC2209, but Chinese manufacturerers stuck with the TMC2208 layout. I will try out inverting the endstop logic later as I got a printby LaKi - Firmware - Marlin
Could you please go into detail how you managed to get MKS SGEN L + MKS TMC2209 v1 to work with sensorless homing? I tried setting everything correctly in Marlin and connected the "middle" pin (the one facing toward the mid of the driver) to the endstop pin, but M119 showed X and Y to be always triggered. Could you perhaps show a picture of your setup and share your config? I would really apprecby LaKi - Firmware - Marlin
