I was using TurboCNC on a lathe and was having problems with the interface. I connected direct via the parallel cable.
As advised by Gecko drive, I installed a Breakout board from Campbell designs. I changed the output pins on the port as required.
On the breakout board, I changed the Jp3 connector to N1 and I checked all power levels as in the instructions. All levels are as described.
I now get intermittent movement in one direction of each axis. I am probably doing something simple wrong.
