Configuration of MPCNC with Duet Wifi2 & Duex2 on RRF3+

Flex12

Hello everyone

I'm struggeling with setting up my MPCNC as an 3D Printer / laser-cutter-engraver.
I'm using independent endstops.
So far i was reading and implementing the changes to the Axles from the following website:

https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_Axis_levelling_using_endstops

I begun with the project under RRF2+ then switched to RRF3+. I noted the changes that were to be undertaken.
I also rearranged the drives different from the declaration:

X axle -> Drive 5 & 2 Remark: Drive 5 is on the Duex2
Y axle -> Drive 1 & 0
Z axle -> Drive 3
Extruder -> Drive 4

my current G-Code who only allows me to drive one stepper motor at the time and also dont stops at the endstop & neither performs the homing correctly.
i would be really happy if someone with a better understanding of RRF3+ than me could give me some hints what to look for.

Remove the duplicate values separated by : as those settings are defined per axis rather than per driver. The only time you must define each driver is for extruders, which are independent axis.

This may be part of your issue.

Please provide the results of M122 and M98 P"config.g"

So I implemented your recomandation of deleting the additional ":" .
Thankfully the Y-Achsle now works flawlessly.
But there is a catch. I was not able to home the X-Achsle in the same mannor, even when i allocated the same switches to it (in the config). Thus i suspect i have a problem with the allocation of the drives.
Next time i plan to rearrange the drives to only use some of the ports on the duet board for the axle movement and use the duex only for extrusion. This might eliminate the problem, fingers crossed.
Thank you agian. Seeing the axle homing correctly was already eleviating my motivation

RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03

Your firmware is 2.03 but your config is using syntax for RRF3. You should update your firmware.

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them. Reboot after each. Use M115 to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.2.2/Duet2and3Firmware-3.2.2.zip
That will get your firmware and DWC up to date.

Finaly i got the time to continue.

I updatet the Firmware and made some small changes to the syntax (endstop flipping)

Now everything regarding the axles works fine.

Thanks again for helping me out. Now im confident i'll finish the Project soon.
