Well, at least you now have a variable speed spindle. When diddling, I noticed that the S commands don't necessarily seem to affect the speed linearly - so if S900 drops the speed, try S899, S890, S850, etc.
I don't think mach3 knows I have a 6k spindle, and therefore won't know, for example, to put the dutycycle at 50% for an S3000 instruction. When I get my tach I'll check.
