as others have already mentioned, it's a Cartesian, but with H-Bot motor config. (two motors for Y-axis)
You have to keep that in mind for drive mapping. Even homing with two Y-endstops is possible.
Before reading the above documentation I made it to this point.
Thanks for putting me back on track!!!
Hey Phaedrux, re-flash worked; got an IP address/DWC. I'm learning. Til next time,
If you don't have a config file ready for RRF3 nothing terrible will happen, you just won't have any functionality since the endstop and heater syntax is completely different.
