Turn the feed rate up.
Just sounds like very low feed rate and because your using R&P with possible Low resolution then your motors are hardly spinning. Where as at rapid they are spinning at higher rpm so sound better.

What drives and power supply voltage did you end up with?

[Duffman]

They are still the same ones running at 36v Clive only I made up a gear box at a 3:1 ratio running far smoother now. Il work with the drivers until they die and then upgrade to a better set lol

Well you could try measuring the voltage of the power supply when it is under load cutting the circle and see if it drops much


edit Not sure who I have answered now Davo242 or Duffman !!

Ok if it does Clive do u think il need to change my drivers because I cant give them much more juice ?? Funny tho it jogs in both directions at once
