Re: [CAD_CAM_EDM_DRO] Servo only moving one way

Here is what to check
1. check that the software is configured properly in that the dir bit is the
correct one for the pin used by the X axis dir servo amp
2. check the cable from the parallel port to the servo amp
Not all 25 pin cables are wired straight through.
3. If you are using the Gecko G320 drives make sure that the +5 from the PC
is connected to the common terminal of the G320. (term 12)
4. It is possible that somehow the parallel port is damaged for that pin.
Try reconfiguring the software to use another pin for the dir signal and
change the wiring to suit.
