I have a Central Machinery (HF) power feed on the X axis of my RF45 clone mill and it's acting weird . Works fine on the fast move buttonbut the speed settings are messed up . It doesn't start turning until I get to "2" on the dial and by the time it's up to 3 it's going full speed . It just started yhis , today is the firt=st time I've seen this . When it was working right it would start before I got up to one and would ramp up perfectly as i turned it up . Am I looking at a bad rheostat or maybe just dirty ? Should be clean , that unit is sealed up tight - but ya never know .
