We have a Mits MV5C with a 610 Meldas control. When we started it up today, it lost the axis location. I checked the battery, and it was reading 3.5 volts, which is good. I reset the axis locations, but the Z was not quite right. When we tried to change a tool, the arm got into a bind. I tried turning the nut at the top of the machine and the shaft broke. The tool arm is still in a bind... Does anyone know someone in the East Texas area that can work on it at a reasonable price?? Thanks. Mark
