Duet 3 - Motors only respond properly duing the home command

@Oliver3d are you sure because your steppers and endstops are a bit mixed:
M569 P0.0 S1 ; physical drive 0.0 goes forwards
M569 P0.1 S1 ; physical drive 0.1 goes forwards
M569 P0.2 S1 ; physical drive 0.2 goes forwards
M569 P0.3 S1 ; physical drive 0.3 goes forwards
M584 X0.0 Y0.1 Z0.2 E0.3 ; set drive mappingbut the endstops have different order:
M574 X2 S1 P"io1.in"
M574 Y2 S1 P"io4.in"
M574 Z2 S1 P"io3.in" -
@JoergS5 Yes this works correctly. Each axis homed independent from the others
-
At the moment this is my only idea: endstops and stepper don't match, so stepper positions are initialized wrong.
-
@JoergS5 I just tried homing all and manually activated the endstops individually to check the corresponding motor stopped and all worked as expected
-
Another idea: M114 will report the current XYZ positions. You could trying validating if positions are calculated correctly.
-
Another idea (I don't think this is the reason, because acceleration is low).
M203 X18000.00 Y18000.00 Z18000.00 E1200.00 ; set maximum speeds (mm/min)
set 18000 to 3000 e.g.
18000 are 300 mm/s and maybe too high.
And validate the current, 2000 could be too high if it's a Nema 17 (M906). Do your steppers get hot? -

And where is your hotend now? Your printer thinks your X and Y are bottom, Z top. Are the endstops same type (active high, low)
-
There is a specific section about endstop testing: https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches

@JoergS5 hotbed is centered on the bed at the maximum hight. So I believe X0 and Y0 are showing that it’s centered on the bed. And the Z600 is showing that it’s 600mm above the bed.
-
I agree, so it's correct.
-
But Z 600 is strange, because config lowered Z by 5 and the XY to center, it should be 595.
-
@JoergS5 After homing all then it reads Z595. For some reason when I did the individual homing of each axis it stayed and Z600

could you please show an screenshot which button you press and tell me what movement the printer does exactly? (the jog which does not work)
-
-
@Oliver3d the Z bottoms seem to do nothing, Y bottoms seem to move the motors very slowly, X bottoms seem to work better but its hard to tell if its 100% correct as I think more than one motor should be activated to create the correct movement in ether X of Y axis

At the PanelDue those buttons did not work sometimes, so I prefer movement in the command line at the top. Could you try G91 and then G1 Z-100 etc. at the command line?
-
@JoergS5 none
-
or better with slow speed:
G91
G1 Z-100 F100
G1 X100 F100(did you try lowing current and speed? I configured a 2A stepper for 4 A and it stopped moving totally)
