I have a question for any of you using stock screws with the G0704. What should I set my Kernel speed to in Mach3? I left it on the default (25 kHz I think), but I did notice I'm awfully close to over running the Kernel with my motor setup. My steps per are around 16000...yes 16K not 1600. When I was first calculating my steps I misfigured and entered 18000 and I got a message stating something like my motors were running faster than the Kernel would allow.
I gotta get me a lathe and order me some ball screws, but that's not going to be anytime soon.
