Title: A Axis
Post by: lpz on November 07, 2007, 01:50:25 PM

How to convert "A" to degrees from Revolutions. EX. when my code = A1 ,my rotary head makes one complete revolution. I need the rotary head to move 1 degree when the code shows "A1", 360 degrees when "A" code =360.
Thanks for the help

It sound as if you need to divide your 'steps per' by 360 in the motor tuning window.

Thank you that worked. Now the next problem. The A axis is working properly as far as steps but it does not respone to the neg. value in the gcode that's running. It reads the line of code as if its always positive and doesn't go in reverse. I cant get a back and forth motion that's in the code created by protowizard.
Thanks again
