Hi John,
I cannot run the DriverTest.exe on my laptop as it is Window 8 and can't therefore load Machs parallel port. Without having the screen open in front of me
struggling to make sense of you description however:
38.44, long 44.12
sounds very much like the longest and shortest times of a nominal 40us period square wave. That suggests a timing
jitter of 44.12-38.44=5.68us, not brill but not too bad either. It represents your PCs ability to generate accurate pulse streams, because your PC has to do
all sorts of tasks like running Windows and all its services and Mach and any other software you have running it cant concentrate on it alone and so you get
this variance, in this case about 14% of nominal period.
There is a problem tho if your Estop button cannot signal Mach, if the BoB cant talk to Mach then its pretty fair that Mach can't talk to the BoB and can't
send pulses to the motor drives.
Can you take the lid off the control box and take some pics. I'm hoping that the BoB outputs have LEDs so you can see at a glance whether they change
in response to Mach commands. I'm of the opinion that Mach has not enabled the breakout board, maybe an enable signal or signals or maybe a charge pump
signal.
Can you post some screen shots of the first four pages of Config/Ports and Pins?
