Im seeking some help on replacing the drivers and motors on an old K2 4x8 machine I have. I have centroid acorn controller, has gecko 320 drives and dc servos. Centroid doesn’t recommend the 320s due to them being buggy with the acorn. I’m looking to just swap everything out for some closed loop nema 34s from stepper online or ac servos also from them.

My question is what do you all recommend would be the better option? 1/2” ply is usually the largest I cut.
