how to convert a mill to cnc?

The acceptable level is whatever you are prepared to accept

If the sloppy slide is tight enough to resist the cutting pressure you can then correct backlash with software.

thanks for info, the table should not move under cutting pressure so backlash compensation should help. been looking at the nema 34 kits from zapp and woundered if they were powerful enough but dont know what size motors i need
