gentlemen; i was machining a guitar in 2" blue styro foam when mach froze, i had to close mach and reload and all was fine. i was past half way the code when it froze, i was doin' 120 ipm. this the second time this has happened. i built my machine, it's direct drive, 5 start,hobby cnc board and steppers, it's pulsing at a little over 27k, 1/8 micro step,i think my steps per is about 3200, i really can't get my steps per set right because it moves to fast to read the dial indicator revolutions. any way to slow it down? thank you for your help, richard stanley.
