General Mach Discussion / 2nd LPT port. Inputs setup.
« on: June 13, 2008, 08:55:21 AM »
Hope someone can help... I've read other relevant threads but problem not solved.
Here's what I'm trying to do: Connect 7 inputs from the Mill to Mach3. 5 of them are on LPT1 and the other 2 will have to go on LPT2. I've fitted the second LPT port and tested it with a printer. When I switch the port addresses around in Mach3 the motors seem to work but not homing properly. So at least Mach3 can see the 2nd port. Put ports back to their original order and all homing works fine.
Testing port2 pin10: Enabled OK. Set to active high or active low, watch diagnostics screen and... nothing happens if I short the pin to Ground or to 5V.
What am I doing wrong??
