MPG Interfacing problems
« on: May 14, 2010, 02:14:46 PM »
This is my first post on the Forum so I hope this topic is in the right place.

I have been having problems getting my PC to initialise a second parallel port which I am using to drive my MPG via a CNC4PC C22 board.
The board works fine when I manage to get the the port to be recognised by Mach3 but its is very temperamental.

I have tried several PCI cards from from different suppliers including the SIIG JJ-P00112-S6 which others recommended but still no luck when the machine boots.

After spending several evenings trying everything, I stumbled across a way to reliably get it to work.
This involves pressing the Reset and then going to "config, port & pins, "deselecting the" enable pins 2-9 as inputs" checkbox and applying the change.
Exit the config menu. Press Reset again and go back to the Ports & Pins menu and re-enable the "enable pins 2-9 as inputs" and apply the change.
From then on the port works fine including if you close and restart Mach3.

As soon as I reboot the machine I have to do the whole thing over to get the port back.

Does anyone have any idea on how I might fix this, or, worse case, a work around.

I hope this made sense and someone has some ideas.

Cheers
John

Yes that could well be it fixed, I talked with Scott earlier and he mentioned that Brian had indicated it was in the driver so updating Mach should help.
