General Mach Discussion / List of suitable PCI parallel ports

« on: November 18, 2009, 01:26:51 AM »

I remember reading somewhere that there was a list of suitable PP's that work well with Mach.  I've been searching but can't come up with it.  Does anyone have a link saved?  I'm looking for a bi-directional port so I can use pins 2-9 as input.  I have two cards here and both work fine other than neither one supports 2-9 as input...unless there is a trick to making that happen.  I did enable that in ports and pins and I didn't see any jumpers on the cards.

Thanks

General Mach Discussion / Source for servo motors

« on: November 17, 2009, 03:13:56 PM »

Does anyone have a good source for servo motors and encoders?  Looking for something that would be compatible with the Gecko servo drives, so less than 80V, 20A.  Thanks

Thanks guys...I made a simple test rig with 5 buttons to ground 10, 11, 12, 13 and 15.  Turns out the PP was working fine.  I had a bad cable.

General Mach Discussion / Second parallel port for use with THC

« on: November 13, 2009, 10:08:40 AM »

Hi All..

I seem to be having an issue with the second parallel port.  It seems to install fine and device manager thinks it's working.  If I check IO addresses from a DOS command prompt using debug it looks like the second port is at 0x278 but when I look at its resources in device manager, there are two lines.  The first is 9000 - 9007 and the second is 9400 - 9407.  I've tried 278, 9000 and 9400 in Mach with no luck. I'm coming to the conclusion that the PP is no good and I've got another (better) one on the way.

In the mean time, is there a simple way to test the PP port in Mach by grounding certain pins?  If so, which pins and where would I look in Mach to see results?  Any other thoughts on the topic would be greatly appreciated.

Thanks very much....
