I have CNC'ed my HF Model 33686 only to have nothing but problems with this machine. I am having problems with my motors stopping intermitently mainly the Y Motor. When doing test cuts on parts not under any load or under load it doesn't matter when after about 45 minutes of running the Y axis just stops working where by the motor loses power and will not come back on unless i turn the whole machine off and back on again, after which it will run again until it decides to shut back down. I am using the folowing parts
Antec 50V 16A Unregulated Power supply
Gecko G202 Stepper Drivers
Sanyo Denki 710 oz-in stepper motors
Winford Engineering PC Parallel interface board
X & Y Axis are using the existing lead screws until i can get them replaced with ball screws
Z axis is using ball screws
