For those who'd like to see my configs for the Duet 2 MK3 here are all the ones I edited and I've also included my Z gantry level macro that mimics the Z calibration done on the MK3.
So far it's working great print wise. Remember that I'm using 0.9 degree motors on X and Y and I'm using the Bunny Science 3.5:1 extruder add-on for the extruder. You can easily change those settings in the config.g file.
So for a stock MK3 you'll do the following:
M92 X100 Y100 E280 instead of X200 Y200 E475
That's all you'll need to change from my config to use this on a stock printer.
Thanks to Christopher Tilley, Ocie Ward, and Steve Aylor for helping me through the growing pains of building the duet firmware.
