any tips on depth/speeds, bit angles etc. basically I need to know where to start my experimenting. I have a laminate trimmer 30k rpm.. should I get one of the cheap router speed controls?
And with the diampnd drag, how do you set the drag pressure - spring loaded tool holders? or do you set the Z to go say .002 -.005 below the surface?
diy cnc router, mach3. want to get the vectric software.
newb here thanks for any tips or starting points!
