@droftarts Thanks for the keen eye. This behavior didn’t start until I just updated to 3.4.0. I will update my homing files and see if that fixes the issue.

I am experiencing a very weird issue when homing X. Every time I home X after the initial home 3.9 mm is being added to the new ending X coordinate. Resulting in a cumulative error after multiple homing sequences such as with bed leveling. Y and Z home normally and have a repeatable ending coordinate as expected. Setup , diagnostics and config files are below. Any suggestions are appreciated.

setup is a Duet3 MB6HC with a revision 1.2 toolboard in an SBC setup with an RPI 4

@chrishamm @Phaedrux
I ended up having to delete the existing config files one by one through DWC and create new ones through DWC. That fixed all access issues.

I am currently unable to upload or save changes to existing system files. When I try to upload a file or save a change to one that is already there I get the following error:

Failed to upload bed.g
Operation failed (Reason: Access to the path '/opt/dsf/sd/sys/bed.g' is denied.)

I am running a Duet 3 MB6hc with an Rpi in SBC mode. I recently had to reinstall the software on the PI due to a bad SD card. I copied and pasted my old config files into the directory on the PI. Did the folder permissions get screwed up? Is there a command I can run to try to reset the folder permissions?

Thanks

I have a Rpi 4 that will not boot. I can read the SD card in my computer and access the folders. I am trying to locate the config.g file on the SD card so I can copy it and try to reload the OS. I believe I have a corrupted boot image as it hangs during the initial boot sequence.

Thank you for the keen eye. I must have not done the M997 command to actually install the new firmware. The motor is operating as expected now. Thanks

Thanks I thought I had upgraded the main board as well. I will try making sure they match first and post my results. I appreciate the help.

@phaedrux as soon as I get back in town from my work trip I will provide the information as requested. Thank you for the help with troubleshooting.

Looking for help with a issue with the stepper driver on my Duet Toolboard. Just installed the Toolboard connected everything and Toolboard firmware updated. The Toolboard boots and everything works as expected except for the stepper motor. When an extrusion is called for the stepper motor energizes but will not rotate. I have tried this with hotend heater on and heated to above 160 and with cold extrusion allowed no change to stepper motor behavior. I confirmed the coil pairs of the stepper motor using my multimeter and confirmed stepper was wired correctly. Still no rotation of stepper motor. This same stepper motor works as expected when connected to main Duet 3 board. I have tried several different stepper motors that are known to be good and working. I am at a loss of what to look at next. I think the stepper driver is bad on the board. Upon board inspection I don’t see any damaged components or solder bridges. Any help would be appreciated.
