@Phaedrux thx. I didnt find out how to, so I tried a bit and got this one working: 
G91 ; relative positioning
M574 Z1 S1 P"!0.io5.in+!1.io0.in+!1.io1.in+!1.io2.in"
G1 H1 Z40 F600
M574 Z1 S1 P"0.io5.in+1.io0.in+1.io1.in+1.io2.in"
G1 H1 Z-350 F600
G1 H2 Z1 F60
G1 H1 Z-10 F60
G1 H2 Z-29 F600
G90 ; absolute positioning
G92 Z0
Hi,
I got 2 questions regarding configuration options of multiple endstops.
Iam currently building a lasercutter and want to controll it with a Duet 3 Mainboard (6HC) & Expansion 3HC. The Z-Axis got 4 leadscrews so 4 stepper move the axis. Each stepper have its own endstop. For some reason, the endstops doesnt switch exactly at the same position and the bed is not leveled after homing. Also there is not much space to create adjustable endstopmounts so I thought it might be easier to add some kind of offset to every endstop for example:
Endstop 1: 0.5mm
Endstop 2: -0,2mm
Endstop 3: 0.0mm
Endstop 4: -0.5mm
Is it possible to add an offset to every endstop?
My 2nd question is: those endstops get triggered in wide range (0-25mm). After homing I use G92 Z25 to set the position. But if I switch power on with a bed @ lets say 10mm, the endstops are already triggered and the position gets set to 25mm. I already thought about using M574 to invert the endstop, move down the bed, invert the endstop again and move up the bed but maybe there is something like "if endstop is already triggered"?
best regards
Ronny
I just did another try, still no wrong connection. Also I added G4 S5 to my config.g
Thanks everyone 
@dc42 there is no G4 command in config.g. my config.g got uploaded to the first post, if you want to take a look at it.
After powering off, I did wait for 30 or 40 minutes, powered it on and didnt see wrong directions. Do you want me to add G4 command or wait to verify that the bootloader update fixed the issue?
@veti I just checked it,
M122 B1:
Bootloader ID: not available
after update:
Bootloader ID: SAME5x bootloader version 2.3 (2021-01-26b1)
I will switch it off, wait a bit and try again. Thanks
hi everyone,
I have an issue with my Expansion board. It looks like the stepper direction is sometimes wrong.
Printer is a new built Voron 2.4 (Core XY), it`s controlled by Duet 3 6HC + 3HC and Paneldue. Firmware: RepRapFirmware for Duet 3 MB6HC 3.3RC3 (2021-05-26)

what happened:
-started a print, but extruder didn`t extrude, it was rectracting.
-I stopped the print, went to config.g (thought I messed up something)
-changed extruder direction from S0 to S1 (still wondering because i remembered S0 to be correct)
-clicked save, board restarts, tried again, wanted to extrude, but extruder did retract.
-changed back from "M569 P1.0 S1" to "M569 P1.0 S0" and it worked correctly
Some time later, it did it again, I went to config.g, hited save (without changing anything) to get the board restart and it fixed the issue. I already checked all connections without finding any issues so I connected the stepper from 3HC Driver 0 to Driver 1, changed config.g to:

and some time later, it happened again. Yesterday I changed A/B stepper from 6HC to 3HC and connected the extruder stepper to 6HC:

I just powered on the printer, did a M564 H0 to test directions without homing and x/y axis direction is wrong X+ gives me a X- movement and Y+ gives me a Y- movement.
Iam not sure yet if this always happens after powering on the board when it was off for some time, I think, if i switch off power and switch it on again, it might fix the issue aswell. Is there anything else, I can try? I uploaded config.g and Diagnostics (M122) while the issue appeared. Hopefully some more experienced user can see anything.
Also I dont see a difference in the LEDs (Vin, 12V, 5V, 3.3V are always on, DIAG LEDs are flashing simultaneously (6HC and 3HC)
