One step forward, two steps back.
« on: May 19, 2017, 09:02:27 PM »
Had a newer PC (Win7) than the one that came with the system (WinXP) so I got a PCI/Parallel card  to go in it and transferred all my software to the new PC, including my XML file with all my settings. Had to change ports to Port #2. Everything looks normal but when I jog the torch, the X,Y, and Z settings change but there is no movement of the torch.  What have I missed?

I think I found the problem. The new PC has a 64-bit OS.

the choices are use an external motion controller which will allow you to use your PC as is OR change OS to 32 bit
Windows 7 or earlier.

Changing OS and using a parallel port it certainly doable, many CNCers do exactly this. The PP can be a bit cussed tho.
Some PCs do a good job when others don't without any particular reason. Additionally PP is VERY sensitive to other software
running on your PC, should your browser auto start say part way thru a machining job the PP will almost certainly stall
and lose the plot.

Given the sensitivity of the PP to PC and/or installed software provided the impetus for external controllers. There are a number
in the $100-$200 bracket that perform well. The companies making them have been around a while and back them up. Don't
buy a cheap-crap one from a no-name supplier, the forum is littered with posts from people who've bought such units and can't
get them to work.
