I ordered a 30x48 last week, same config as yours. I'm trying to gather all the necessary parts for the build and you're probably ahead of me here. I'm trying to figure out the electrical requirements; it ships with a 48V PS, but it looks like we'll need a 12v PS for the limit switches and maybe 5v for stuff like additional probes. How are you handling the 12v requirement, with a DC-DC stepdown or a separate 12v dedicated PS?
I ordered a
2.2kw high torque chinese air spindle from ugracnc for my cutter. Never messed around with VFD's before, but it looks like it's fairly easy to integrate with the MX3660.
