Hi everyone could some one please tell me what setting on mach 3 should i use for M8 thredded rod as my lead screws on the X Y Z
I hope this make sense

as in steps or velocity acceleration

many thanks steve

goto the mach site and look under the tutorial vidio and trubleshooting at the bottom
this shows how mach will set the steps for you. acc. is up to each machine,if you set this to high the steppers will stall or sound bad.
