General Mach Discussion / can not calibrate axis
« on: September 04, 2008, 07:36:50 PM »
i am about to pull all my hair out. i have a knee mill i converted with 3 stepper motors  3 kl4030 driver cnc4pc breakout board and a 36 volt power supply i have tried everything to calibrate my axis i have used calibrate axis button if i calibrate axis for 4" then go to mdi line and type y 4 the axis moves exact 4 then y -4 it moves exact if i type y2 it lacks about .25"then is i type y 6 it over shoots by .1 if i calibrate for 6" then six is exact  or if i do 2" it is exact.  i took a dail indicator and put on the axis and turned motor by hand and counted revs and figured how many /inch and multiply by my micro step by 200 for 1.8 degree stepper this was not even close on movement can noise cause this or maybe its my computer i have spent about a week trying every thing i can it is driving me crazy
