I have finally gotten a chance to go through my router and refine a few things. I was running a 2 3/8" spoilboard surface cutter and it cuts just fine going on the x axis, but on the y axis is stutters enough to cause the gantry to wiggle just a little bit and my cutter shows it. Once it goes to cutting on the x axis it goes right back to smooth with no issues. I took the drives apart and nothing is loose, and the belts are tight. Any suggestions as to where to look? Mach 3 settings? Maybe a little wiggle is to be expected at this level of machine?
