@T3P3Tony I tried a different SD card. I also booted it without the SD card first then sent M21 to force mount it via serial and that mounted it. However when running M20, no files are detected and when running M39 I get this:

SD card in slot 0: capacity 7.95GB, partition size 7.94GB, free space 7.92GB, speed 22.50MBytes/sec, cluster size 32kB

I will attach an image of the SD card slot soon when I get home but no visible damage or solder faults.

When I start my board with my SD card inserted, the com port won't show up. It doesn't connect to wifi either. I reinstalled the firmware (double click reset and upload) and I also flashed the SD card and put a backup of the old files back into it. I'm not sure what I changed or what happened but it was really random. I am using the DUET3d 5+ mini board.

Some debugging: As soon as I take the SD card out even if it is already on, I see the COM port and can send serial commands.

@coolj Did you do it with a nema 8? Please could you provide your code?

@jay_s_uk Thanks I fixed that but with sensitivity set to both -128 and -64, I get no triggers in the console when I have R1 included in the M915 command?

@moth4017 The issue is that it does not go into stealthChop mode despite the M569 line of code

I am trying to home a Nema 8 motor that is coupled with a leadscrew however I am unable to get the sensorless homing to work at all as it is always in Spreadcycle mode even when I use M569 V10. I'm using the latest duet3d version for the firmware and I am using a Duet3 5+ mini. I have attached my code below:

Drive 0 runs forwards, active low enable, timing fast, mode spreadCycle, ccr 0x00053, toff 3, tblank 0, hstart/hend/hdec 5/0/0, pos 516

Does anybody know what is going on here and/or how I would be able to fix it?
