General Mach Discussion / mach 3 froze

« on: March 20, 2013, 09:10:14 AM »

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.

General Mach Discussion / stepper squealed

« on: February 15, 2013, 02:12:35 PM »

dear gentle men: i was cutting blue foam on my new home built router, all was going fine when a stepper let out a loud squeal and then ruined the part. is this loosing steps?
i,m trying to set my steps per unit I'll use my dial indicator  today.
what do you think happened? thank you very much, also since all 3 axis are using 1/2" single start 10 pitch acme screws , shouldn't the steps per be the same on all 3 axis? 
thanks again, Richard from watts, OK. out.
