Port 2 Pin2-9 Mach3 Problem
« on: June 06, 2014, 05:31:13 PM »
Hi all

We have c23 bob card from cnc4pc. Everything is looking ok about the bob card. Port 1 IO s is working. Port 2 outputs too working. But I have a problem with inputs of port 2. I can using input pin 10, 11 etc. But I cant using input pins 2-9. "Pin 2-9 as inputs." Checkbox is checked from Port setup and axis selection in ports and pins menu. I am sure about I have a signal on my lpt port card on pci express. I checked it. But I couldnt read any signal from mach3. I tried to use pin 2-9 inputs on my first lpt input (which lpt port is on motherboard). I didnt get any signal on mach3 again from 2-9 pins.

Where should I look for this problem, what should I check too and what should I do. Thanks for all replies, ideas and helps....

Check to see if the C23 allows you to use 2-9 as Inputs.

Lots of threads out there about this, but haven't found many that ended with working inputs on pins 2-9 on PP #2.  Usually a PP card issue.

I have the same problem with a C11 on PP #1 and C10 on PP #2.

My Input needs are as follows:

Touch probe
Spindle Speed Index
3x quadrature encoders for DRO

I wanted to use separate limit switch inputs for each axis but had to combine them all since I have only the 10 inputs.

Some have tried a SYMA PP PCI card with  success.
