why does the blue box need a smart motor? Was hoping I can eliminate it for a normal nema23 Does the grey wire out of blue box go to the torchmate box then the plasma cutter trigger get wired to the blue box? Does this wiring look ok or am I missing anything? Anyone have a stock 2x4 profile? When trying to jog this at anything other than slow speeds it just binds up. Got it used and last owner said he had no issues. He was using TM4 but I have 4.5 downloaded Anyone know what size cable track I should use on the 2x4? And does anyone know if the bellows on the new 4x4 would work on a growth series gantry?
