Hey,

I Built my own cnc Machine. The signals go over 2 LPT Ports. The problem is, the first Lpt port works normal, but the seccond Port only sends output signals, but shows no input signals. I tested with my voltmeter the Voltage of the input pins on Port 2 (Pins 10-13  and Pin 15). The Voltage was switching between 5V and GND, so the problem has to be in the software. what have i done wrong? I tested 3 days, but i could not find the mistake

I hope you can help me

Sincerly,
Michael

Hey,

Today i thougt the problem could be in "use pin 2-9 as inputs". I activated it and bridged the contacts with some cables, so that the input signals were going to the pins 2-9. but tere was also no reaction by the program to inputs.

Has onybody an idea?

Michael;)

Has nobody an idea???
