Done quite a bit of searching....... I have a 24" Mahr Motorized Height Gauge that I would like to retrofit to LinuxCNC. The existing glass scale is damaged and I cannot get repair parts from Mahr. Very low current draw on the DC motor, the original system would run for 8+ hours on 4 D cell batteries. Anyway, what would be the easiest servo implementation via LinuxCNC? The retrofit will include a 24" linear encoder (TBD) and we are shooting for sub micron resolution. My intention is to get the system driving via the software then start building macros to be able to duplicate the gauges original measurement routines.
