Hello again everyone,
Well, I have my cnc router working pretty good except for a few minor issues..
I have a ‘homebuilt’ 3 axis flatbed CNC router. The stepper motor chopper boards can be set for 1 step, ½ step, ¼ step, 1/8 step and 1/16 step. What are the differences between these setting and which one should I use?? Right now, I have all three motor choppers set for 1/8 step ( ...just picked it out-of-the-blue). The ‘X’ axis motor is on a 2:1 ratio, the ‘Y’ axis is on a 1:1 ratio and the ‘Z’ axis is on a ½” per turn lead screw. Should I change the step setting on any one or all of the motors?
Also, occasionally I have experienced a few motor stalls both during operation and during jogging and the ‘Y’ axis has a ‘jerky’ ramping motion. Could this caused by a motor tuning issue?
Thanks a lot for your help,
Dale
