Chris what software are you using to generate the code? . Last time I made inquires into the micro coding problem I was told it was WAY TOO COMPLEX to deal with on a simple( low cost) level. They ALL said the same thing(;-)
YOU have made a good point on machine resolution that MANY manf of comercial CNC machines design into the machine. THEY do not use any more resolution than is need to maintain the accuracy of that machine. THat takes the unneed load off of the CPU.
I fall into the same thing at 40,000 steps per unit just to do .001" accuracy. I am using way more resources than what is needed to do the job(;-) BUT this is a test machine designed to run mach hard for testing purposes (;-)
SO how did changing the microsteps turn out??
(;-) TP
