What's the enable pin read on your multimeter? I'm just guessing, but perhaps the driver module doesn't supply voltage to that Vref potentiometer unless it's enabled???

Hmm... I'm just guessing, but --- on most DRV8825 modules that I've seen; enable needs to be low to activate the driver; and you've got it showing up as high....

> Vmot is not connected Actually, I think that may be your problem. The DRV8825 driver gets all it's power from Vmot... including the power to the current set potentiometer.

The SD driver can only read filenames with up to 8 characters in the name; and the firmware expects an extension of `.nc` This should work: `test.nc` But this won't...

That’s... odd. I’ve looked the file over on my iPhone; it looks functional (it’s got some strange extra moves in there and it keeps switching from absolute to relative positioning...

Sounds like a bug in the character filter... GRBL itself can’t handle anything but pure g-code; it depends on whatever is feeding it to filter out comments and other non-supported...

@littledrumer - The software doesn't even initialize the SD card until you access the "SD Card" menu item in the main menu... so, yeah, probably a hardware issue. @Elpablito -...
