Duet 3 - Motors only respond properly duing the home command
-
I mean in the sys subdirectory.
-
This is what I have on the SD card I had some problems during the initial setup because I replace some of the files on the SD card with some incorrect files but I thought I had fixed the problem buy downloading and installing all new files
-
An additional idea: are the endstops and steppers corresponding? (X stepper to X endstop etc.) because if Y is stopped by X endstop etc., this would explain why Y moves if you want to move X etc.
-
@JoergS5 Yes I have checked this all are connected to the appropriate motor.
-
This is the contents of the sys folder on the SD card

Could you try the homing movements, but one axis after each other, whether this works:
G91
G1 H1 X815 F180 ;
G1 H1 Y815 F180 ;
G1 H1 Z815 F180 ; -
@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)
