I have been struggling with this problem for the last two days, I’ve tried changing various different settings in the Duet setup configuration tool and always have the same result. Motors seem to work exactly as expected when the hoeing command is executed, but when I try to jog the print head in the z axis nothing happens, if I jog in the X axis the Z motor moves smoothly but only that motor, if I jog in the Y axis the X motor moves slowing and not smooth and the Y motor moves as it dose in the X axis jogging. I feel this must be a software problem because the homing cycle works perfectly.
Ive tried all the steps I’ve done so far on the DWC and on the Paneldue that’s connected to the Duet board with exactly the same results. -
I have also tried top complete the delta configuration process but with no luck as I can’t get the head top jog down to the bed the DRO numbers are moving but the motors are not.

I am not sure whether your homing procedure is correct:
G91 ; relative positioning
;*** Slow homing has been configured. Change F180 to F1800 below when your configuration is working
G1 H1 X815 Y815 Z815 F180 ; move all towers to the high end stopping at the endstops (first pass)
G1 H2 X-5 Y-5 Z-5 F1800 ; go down a few mm
;*** Slow homing has been configured. Change F180 to F360 below when your configuration is working
G1 H1 X10 Y10 Z10 F180 ; move all towers up once more (second pass)means G1 movements with H1 parameter is individual motor mode and stopping at endstop, so it will stop when one of the axis is stopped.
In https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter it is more like:
G91 ; use relative positioning
G1 S1 X300 Y300 Z300 F2500 ; move all carriages up 300mm, stopping at the endstops
G1 S2 X-5 Y-5 Z-5 ; move all towers down 5mm
G1 S1 X8 Y8 Z8 F500 ; move towers slowly up 8mm, stopping at the endstops
G1 S2 X-5 Y-5 Z-5 F10000 ; move carriages down 5mm
G90 ; back to absolute positioningSo S1 instead of H1 and S2 instead of H2.
The movement problems can then be due to one axis set correctly, but the other two not, so the printer thinks he is somewhere else as he is.
BTW nice printer with ball screws!!

I think I'm wrong, because thread https://forum.duet3d.com/topic/15279/duet-2-ethernet-3-01-rc5-fail-deltahome/2 used H1 and H2 and this worked.
My other idea at the moment is that you defined a tool 1, but no 0 tool. Maybe the movement tries to move a nonexisting tool 0. So T1 at the end of the config file maybe.
-
When I use the “S” commands the DWC tells me that this is an obsolete command and to replace the “S” with “H”.
I have lowered manually the 3 motors to completely different heights and the homing sequence raises all motors at the same speed until they each reach their appropriate endstops and then each motor waits for the remaining motors to catch up before doing the final bounce down and back to the stops.
I’m now going to try the homing sequence you have posted to see if this makes any difference
-
Please see my addition with the tool to select T1.
-
I went back in to the RRF Config tool and changed the Tool to "0" and tested again with the exact same results.

One more idea: is there a sys/config-override.g in the SD card?
-
-
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 ;
