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

[Desertboy]

Was playing in fusion only took 40 mins but not sure how I'd drive the long axis, I think needs to be R&P but have no idea how to set up a dual pinion anti backlash setup. The other choice 2* 2.7m 2510 ballscrew's with rotating ballnut's as at the length it's going to be a skipping rope if I try and rotate the screw.

Does anyone know how I invert the axis in linuxcnc? Using the beta dual ballscrew on the Y so need to edit the hal or .ini to do it as the wizard doesn't support dual motors.


Alright Fusion buffs when I copy an object how do I break the association so my edits to the new object do not effect the original?
