Problems with new Parallel Printer card

Problems with new Parallel Printer card

Postby keith » Mon May 08, 2017 10:34 am

Hello Everyone,

A friend has upgraded his PC and now he can't get his machine to work. :o :o :o

I have checked that he has imported his Mach3 configuration correctly and I think the problem is with his new Parallel Printer card. He has installed this card into his new PC:

I know from personal experience the problems one can have with the Parallel port and I was wondering if there was a list of what cards work or the correct spec when purchasing a new Parallel card?

Can anyone help? :)

Thanks, :D

One of the common problems is that if he upgraded to a newer 64-bit version of the operating system, Mach 3's parallel port drivers don't work. You can check whether Windows is 32 or 64 bit in the System control panel.
If you don’t have time to do it right, when will you have time to do it over?

Yup that will do it every time... My PC failed a week ago and when I installed a new one it had Windows 7 64Bit on it and of course nothing would work.

Reloaded to Windows 7 32Bit and everything works...

However I now need to recalibrate everything. Is there a video that will help me decide on the correct 'Steps per Unit' in the Motor Tuning option of the MACH3 configuration?

I have watched this video https://www.youtube.com/watch?v=KiCLoQmuJ3g and it is a bit unclear...

I thought I once saw a video which showed a method to calculate it...

Thanks for any info anyone can supply

I think there is a video, but also a post or two around here. The jist, from what I remember, is that you use the calibration tool inside Mach3. It lets you input a move (e.g. X 96") and then you measure how far it actually moved. While it seems odd to measure with a tape measure over that long a distance, it will actually give you the best results.

Thanks for the reply Awesomeness, I looked around a bit and I found this one from Bill Griggs:

I will calibrate following his video and report back.... but it will have to get a bit warmer in the garage first ;)
