For my future project (cnc router) I will have to use helical rack and pinion system on two longer axis (2 and 3.5m). There are some designs where pinion is forced against rack with spring tensioner, on the other side, if I follow Atlanta's installation manual for their system, they forbid tensioning pinion against rack as it would cause wear and tear or rupture of teeth (they suggest pre-load pinion shaft).
In my case this will be used for woodworking cnc router, so I'm not looking for very high precision, but anyway if there is anyone heaving experience with this would be nice to hear.
