Same question as bob that Joiner kindly replied to (around 10 questions back) I've compensated for the mitre slot with a sled with adjustable back fence.
However I can't compensate for the rip fence being out by 2mm that has to be table or motor unit correction.
Or either the unit is a Monday/Friday constructed one or classed as a 'rough cut saw because it was under £200.00
