General Mach Discussion / Re: Mach3 is not talking to Breakout board

HI I had the same problem last week. My computer guy had turned of the lpt1 port when he set up the computer.
It looked like it was runing on the screen but was not sending pulses to the break out board. I had to go into the config and turn on the port.
Even though the mach said the port was conected it was not. and the test said everything was good and was runing find.
Somthing like that is confusing to say the least.
It said it was working but the pins didnt show any response to voltage change.
Also if your pins read 5 volts at rest do you have your mach set to pin low or pin high.
I have mine set to operate at pin low voltage. it will not run at pin high.
THIS MEANS THAT IT SENDS a pulse when the voltage is turned of not when it is turned on.
