Looks great!
I’ve built 2 of these LR4’s now and they are easier to build than an mpcnc (which I built mine 2x) and with properly calibrated parts and very stiff. Yes, squaring mpcnc isn’t exactly simple either with the bearing clamp tightening procedure for the core. I’m going to convert the MPCNC to a lowrider beta.
@Ryan do you have an MPCNC conversion kit? rails, z screw motor couplers?
