I had a little trouble with my left motor. I used the level bubble technique and right motor worked great. Left motor would do 5 and 1 degree increments fine but .1 degree it jittered a bit each time then jumped close to the 1 degree movement after what was supposed to be only .3 degrees. I eventually got it but it was a little temperamental. I haven’t measured any cuts to see how my accuracy is yet.
Edit: bubble technique Sprocket Alignment Technique
