Weid stuff when homing.

[Snippy]

Printter does not home, just mooves abit towards the endstops when told to home all.

@Snippy if they are NO switches, add a ! to each pin name. E.g. M574 X1 P"!io1.in" S0 ; configure X axis endstop

[Snippy]

@jay_s_uk
No difference

[jay_s_uk]

@Snippy how do you have them wired? can you post photos of the wiring?

[Snippy]

@jay_s_uk

Io0.in
GND

[jay_s_uk]

@Snippy just noticed you've also configured them as S0 in M574. You should be using S1 for switches

@jay_s_uk
Lol thanks, allso it was homing in the wrong direction
M569 P0.1 S1 D3 V2000 ; driver 0.1 goes forwards (Z axis)
M569 P0.2 S1 D3 V2000 ; driver 0.2 goes forwards (Z axis)
M569 P0.3 S1 D3 V2000 ; driver 0.3 goes backwards (X axis)
M569 P0.4 S1 D3 V2000 ; driver 0.4 goes backwards (Y axis)
So S1 to S0

@Snippy all working now?
