+# HEPHAESTUS Wiring
 
 This is how I have my LinuxCNC machine wired. I put a linuxCNC box in place of a Southwestern Industries TRAK CNC II control box. I am reusing the TRAK drives, motors, and encoders. Eventually, I switched to using linear encoders instead of the TRAK encoders.

 ## 7i37TA
 
 Three enables are used - one for the X and Y axes, one for the z axis, and one for the spindle. This allows the z axis to be disabled independently for manual drilling operations.
