General Mach Discussion / Re: Mach3 via USB?

According to Quatech, the card puts out 5 volts. I didn't actually test this but I suspect it's true. I think Barker is probably right, the problem lies in how the port really functions. The fact that a DMA can't be assigned is a serious problem here. It would mean that memory management would always suffer through the card's port.

General Mach Discussion / Re: USB - Parallel laptop

I have also just gone through this process with no success at all. Brand new laptop. 1.7 GHZ centrino, 1GB Ram, etc, etc. I Tried 2 different PCMCIA to parallel adapters and neither could communiate with Mach at all. I just wanted to use a laptop because I thought it would be convenient to get all of my CNC done on the same machine. I decided that a $20 jump drive makes it easy enough to move files around and causes far fewer headaches.

Thanks for the input. Barker, which device were you trying? USB to Parallel or PCMCIA. My understanding is that PCMCIA cards work much better. Apparently the card bus is tied much more closely to the motherboard.

Thanks,

Greg

General Mach Discussion / Mach3 via USB?
« on: March 21, 2006, 12:22:49 AM »
I have been using Mach3 for a couple of weeks and things are just great. Something new has some up though and I was hoping that someone here might have some advice.

The PC I've been running Mach3 from can't really be the final sollution. I have access to a really nice laptop that would be great, except of course, it doesn't have a parallel port. I have a usb to parallel adapter that may be part of the solution, but it has a centronics type end and will need an adapter. I was wondering if anyone has any experience with this sort of thing. I know that these types of adapters often don't work for specific things. I have also found some PCMCIA parallel adapters but they're a bit pricey. I don't want to buy one as an experiment.

Any help would be really appreciated!

Thanks,

Greg :-X
