And finally you are comparing it to what other motor drive combination?
For me, best way to put an end to it all, crack open your wallet and go buy a good brushless dc drive.
Chinese engineers have for the longest time been grossly over exagerating the max power of their electric motors. Maybe this is also the case?
And on the question of maybe this could be mach3 related, I doubt it. I had an old mill that I could run at 60 rpm all day in direct drive and it was stable and tons of power. I'm willing to bet it's all drive problems.
