Cut an octagon on Friday! Cut was nice! However, i had to turn the feedrate down on the mach3 program run screen. This is after i set the optimum travel speed and set the correct arc voltage. Also, gantry still wants to travel to the opposite end of the table after the "y" axis is referenced. The 2 stepper motors start grinding and the carriage doesn't want to move! On the octagon, all the vertical (y axis) cuts have a rigid finish. Seem to have a racking problem. It is supposed to correct itself after referencing but doesn't! Thanks, Fritz
