Yes to an extent, but bear in mind the available spindle power drops with speed so if you go too low the spindle may stall, hence it's safer to advise keeping the spindle speed near the calculated value.Quote:

Backlash can cause the effect you describe. It could be something else, like a slightly loose pulley/coupling, but that seems less likely since the rest of the part isn't all over the place. If you're machine is driven by ballscrews then you're unlikely to notice their backlash on wood, since it's very small (<0.05mm). That's not the case if you've used ACME or threaded rod...Quote:
