Thanks for the reply Hood,
I was a little rushed in my original post so I will take my time this go around and layout all settings a little better.
I am using the latest DEMO download version of the Mach3 which I downloaded last week. Does the demo version possibly limit output commands?
I am currently running the desktop computer standalone (not connected to the CNC machine’s breakout board) to eliminate other potential issues; so I am looking for voltage with a multimeter at the parallel port on the back of the computer directly.
In Ports and Pins/Output Signals tab I am enabling Output #1 (green check), Port #1, Pin #16, and left active low as a red x (high) but also tried a green check (low).
I am using macro M111 to activate PIN #16: ActiveateSignal(Output1)
I am using macro M110 to deactivate PIN #16: DeactivateSignal(Output1)
To test I go into the Diagnostics screen and enter M111 into the manual code entry line down by the RESET button. In the Output Signals Current State (lower right area of the Diagnostics screen) I get the Output 1 LED to blink red with M111 and turn back off with M110 but don’t get voltage on the actual parallel port pin #16.
Thanks for the heads up that the virtual parallel port LEDs in Diagnostics is not reliable to determine if I am getting a signal on the PIN, I was relying on that and only quickly manually checking with a voltage meter to double check when I got no LED light. Having said that, I am almost certain I check the correct pin, but I will double check when I get home.
