Open program and load a code with say feed of F250 and press cycle start . Program runs a feed rate of 6mm min or just ticking over. Hit Stop , GOTO Zero ,Rewind code and cycle start and away we go...

Converted a few Sieg X3 size mills and an old knee mill to cnc as well as building a fairly reasonable router which comfortably cuts parts for other projects from 12mm ali plate and all I use for my...

Just ran the the circle wizard in Mach3 to test the machine PVC then bit of scrap ali:)

The x axis on the mill when it was cast has a split mount for the circular acme nut much like putting piston rod on crank shaft . The acme nut was 30mm diam and ballnut was 28 mm so just sleeved it...
