MACH3, Dell 2g machine running Windows 7, Parallel breakout and a generic 6040 router. I did have this working when I set it all up after purchasing it some 4 or 5 years ago but it has sat unloved since then. I cut a new instrument panel for my sailplane with it but now want to re-jig things so broke out the system and have been getting everything running again.
The controller breakout was replaced by a NOVUSUN ethernet unit so config was lost, I have now swapped back to the parallel HK breakout board.
JOG works. Lovely and smooth.
Generate Frequency works ... nice and smooth.
But trying to set the steps or run GCode results in stalled and noisy motors.
Break out the oscilloscope after much fiddling ....
In Jog and frequency modes the DIR signal works as expected, only reversing polarity when a change of motor direction is required.
In axis setup and GCode run the direction signal is changing on each pulse step with the result that the motors effectively stand still!
Most bizarre.
Disconnecting the DIR signal allows the motors to step ax expected but obviously with no direction control, defaulting to the drivers default direction.
Any help? ( Ireally want to go and fly this weekend with my new little electrical sub-panel in place! )
