I'm getting tired of living with the chatter and think I'm ready to finally upgrade to the high definition motors. The good folks at Shopbot have suggested that I should also consider upgrading to the new PRS type of Z setup. Our current configuration is a Colombo 5hp spindle on a PRT Alpha strut type gantry over a vacuum equipped table.
Anybody here done a similar upgrade? I know the motors will make a big difference but I wonder if the new Z is worth the additional cost? - Boyd
