General Mach Discussion / Bad Parallel card?

« on: September 05, 2016, 05:14:15 PM »

I'm not getting any change in my pin voltage under any circumstances.  I use my Port 1 378 Port 2 800 and nothing.  Port 1 378 nothing and Port 1 800 gives me an error.  So i'm thinking it may be the 21 pin card I installed on my computer.  Any suggestions on what card to use??

Thanks Wayne

General Mach Discussion / Pin Test

« on: September 04, 2016, 11:57:56 PM »

Hi group, had a quick clarification.  I'm trying to set up my Mini CNC and was checking the voltage on my 25 pin port in back of my computer.  According to what I have read so far I should be able to read apx 5 volts when pressing the arrow keys.  I just tested my top row 1-13 right to left and all are reading 5+ volts without touching any arrows.  Any ideas?

A quick addition, my bottom row 14-25 left to right is reading pin 14-22 is reading 00 and pins 23-25 read 5+ volts with no arrows pressed.


Thanks Wayne
