Will, so the new controller is a drop-in replacement for the one in the Classic? I ask because my Classic Plus (DIY wider belts, replaced spindle shaft, added energy chains) is on its way from storage in California and I’ve been anticipating updating GRBL to 1.1 also. Is the McGillicutty incorporated in the new controller or is it still an auxiliary board (not knowing what the hidden page shows… 
)
Thanks,
Randy
