RE: [CAD_CAM_EDM_DRO] Mach3 & laptops

USB to parallel definitely won't work.

And keep in mind that what you have on the laptop is not really a "parallel port" it is a "printer port". Printers don't care if the data timing is off. Motor drives definitely do.

Yup, a "non-integrated video card" is "one that's not on the mb like
a laptop". Don't know why(technically) they are a problem, but I know they can be.

Why not ask the questions on the mach forum? Might get better answers.

Subject: [CAD_CAM_EDM_DRO] Mach3 & laptops

I was looking to set up Mach3 & a Taig with a laptop, and saw on
Artsoft's website that "Laptops are not supported because the power
saving features of the chipsets disrupt the pulse stream".

What's the real story here? ALL laptops?? I'm kinda having a hard time
believing this. Parallel ports are usually designed to... well, /work/
at transferring data as designed. It's kind hard to even see this
statement as credible, I mean the explanation borders on the absurd,
power management and the parallel port datastream are two different
things. Will this actually not work?

And what's a "non-integrated video card", one that's not on the mb like
a laptop? Why would that matter?

My laptop does have a parallel port built into it. I could also get a
USB-to-parallel port cable. That would add the complexity of the
internal bridge and all but it would use a different data path than the
internal serial port.

Thanks,
Danny
