New build with recycled parts on a ridiculous budget 120cm*60cm work area

If using R&P, yes spring load the pinion against the rack - this takes out 99% of the backlash, but also fit a stop to the motor/plate to stop it being able to disengage or jump the rack if overloaded, a jumping pinion will chew both rack and pinion instantly meaning an expensive fix, far better to stall the stepper.

I use R&P on my plasma table and its been flawless so far.
