I'm having trouble getting my spindles to sync RPMs, I normally do it when picking up a part and parting off, but in this case I am chucking a center in the sub and using it to steady a thin part for turning. I tried using M203 but get a alarm about my chuck condition, I assume it's because it's in closed position. So, just to get the parts going I used M206 for each spindle which sucks but works, only problem is when I call up my tool geometry, T1212, I get an alarm saying tool offset not allowed in polygonal mode?
