Hi,
Im currently upgrading my gantry with an old esab bridge, this uses frction drive which im a bit worried about but assured it will be fine, the servo system that would have been on this table would have had encoders turned by a gear rack on the rails, so if there was wheel slip i think it should have compensated for it?? So with my stepper system can i do this? am i right in saying mach would support encoders and would correct the position of the gantry according to the encoders rather than by the number of steps???
Not really on mach but the other question i have is about the steppers themselves, they are rated to take 90vdc, am i right in saying when you rectify an ac voltage it is reduced? Also can i over supply my steppers with voltage by a little and still not kill them? Im just wondering if i can rectify the 110vac in the shop and run the motors from it to save having a transformer?
Any help would be great
