M574 X1 S1 P"!xstop"
You probably need to remove the !. It sounds like it's detecting that it's already at the endstop when it is not because you have the input inverted by the !.
-
@Phaedrux if i remove !, X goes away from the limit switch.
M574 X1 S1 P"xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop M574 Y1 S1 P"ystop" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin ystop M574 Z1 S1 P"zstop" ; configure switch-type (e.g. microswitch) endstop for low end on Z via pin zstop -
Then either the rotation direction or motor binding of the motor is wrong for corexy, or your homing file is moving in the wrong direction.
https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_coreXY
Give that a read. Do the motor tests and see if your motors are configured correctly for corexy.
The endstop is configured for the low end of travel and the homing file is moving to the negative, so that seems correct assuming the endstop is on the left side of the machine.
-
@Phaedrux x and Y end stops are on the right of this printer. Y axis is homing correctly.
-
If it's on the right, then your endstop definition and homing moves for X are incorrect.
Should be:
M574 X2 S1 P"xstop"G1 H1 X335 F1800 ; move quickly to X axis endstop and stop there (first pass) G1 X-5 F6000 ; go back a few mm G1 H1 X335 F360 ; move slowly to X axis endstop once more (second pass)It's still a good idea to verify the correct motor configuration with the motor tests in that link.

M574 X2 S1 P"xstop"
M574 X2 S1 P"xstop" Still moves X away from switch. I will do some reading.
-
@Phaedrux something I noticed it that when X in moving away from the switch, if I press the x limit switch it stops. X and Y is on a pcb board.
-
Did you also change the direction of movement in the homing files as I showed?
-
@Phaedrux ok so a X is home toward the switch now, but it is at max, look at the photo.

Endstops - X: at max stop, Y: at min stop, Z: not stopped, Z probe: at min stop

OK so I think I have a problem, Both X & Y should be going in the + direction when Homing, X Home in the + direction but Y home in the - direction. So as you can see on the status display Y shows 0 and X shows 350.
How can I fix Y to Home in the + direction. I try changing M569 S0 which flip the X & Y axis.; Drive directions
M569 P0 S0 ; A
M569 P1 S0 ; B -
@Karim This seems similar to my printer voron 2.4 It would be easier for you to debug if you write pin number instead of xstop, ystop. The reason is to make sure x and y motors are not flipped, which happened to me
-
@Ghazi This is a Voron 2.4, All the stepper are wire the same colors, are you going in the + for X & Y direction when homing. How do I know if X and Y is Flip.
-
@Karim I checked my config file. B motor is X and A motor is Y. Check manual page 235
-
@Ghazi ok A & B was mixed, now it home in the + direction, Now my End stops is at MAX.

Endstops - X: at max stop, Y: at max stop, Z: not stopped, Z probe: at min stop -
@Karim Try the old homing file and see if it works. I changed nothing for homing x and y. But for Z I added few lines to move the toolhead above the z endstop
-
@Ghazi Do you mind sharing you Config, X & Y & Z homing files.
-
@Karim I donot have the printer nearby. I can help if you share the homing files you are testing right now

@Karim X & Y end stops M574 define high-end M574 X2, M574 Y2 switch them to low-end M574 X1 S1 p"xstop" & M574 Y1S1 P"ystop". The homing files should move in the negative values -355. Also, did you fix the mixed in wiring A & B motors
-
@Ghazi Ok that make the + movement for X & Y crash into the endstop.
