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.

I was thinking a dual pinion setup to remove the backlash, if I build this I'll put servos on it.

When the time is right I should come down and give you fusion 360 lessons and you can help me with my R&P ;)

Ordered myself a new phone

Cheap Chinese of course have better things to spend money on.
