We need to push a large load (2 tones) using two stepper motors, connected rigidly to the axis (two screws). I'm worried the motors could micro-step out of sync. And cause malfunction. I can see...

We're making something special for the lab. We need a 4m long linear rail, that can push 27kN at 20mm/s speed. Two NEMA 42 motors with a screw could deliver the performance. It's hard to find a...
