Voron 0.1 M5P/CB1/EBB36 - Z Endstop triggers but does not stop Z travel

[Titus A Duxass]

I cannot get Z to stop when homing it. X & Y both function as they should be not Z.

in the machine interface the Z end works as it should.

The Z stepper appears to be configured correctly

I've tried both ^PD2 and just PD2

Any pointers good people?

Try !PD2

I tried that, with strange results.

X & Y home as normal (colour change to blue on the dashboard).

Z now goes in the wrong direction and pressing the Z endstop switch does nothing, but! Releasing the Z endstop switch stops Z travel and both X & Y unhome (change back to orange on the dashboard).

Reversing Z direction gives: X & Y home as normal. Z homes in the required direction until I trigger the endstop but, I get the error Endstop z still triggered after retract and X & Y both unhome.

Update.

I moved the Z endstop switch connect to Min 3 on the board and updated the printer config to suit - it now works. It also works if I move it to Min 4 on the board.

This leads me to think that Min 2 / PD2 is either not working or PD2 is not the correct assignment for Min 2.

I am happy that I've got it to home all correctly but, I am now not sure if the SFS will work.

As I suspected the filament encoder part of the SFS did not work - it was connected to Min 2/PD2.

As a work around I connected it to the proximity switch connector PC15 and it all works.

Just the BTT Microprobe to set up now.

Glad you got it working. That was my next suggestion--move to a different pin.
