Looking for advice on fixing/upgrading my SX3 motor system. Seems that the controller board shipped was bad, it keeps on issuing 'ERR' and beeping n not doing much spinning.
I know there are direct replacements available from both Grizzly as well as ebay and other sources.
I am interested in possibly doing a mod on the machine, would like to get a few more RPM without loosing much hp. Any suggestions on what are the good motor mods for this machine?
Running MACH 3 w/ CNCFusion kit. Would like some spindle control if that is an option. Not looking for serious HP increase, but dont' want to loose much either.
