I recently got a Dell Core D PC, 2.8GHZ and 1GBram to control my machine, the rest is all integrated onboard video. The problem is that I can't find a cheap video card to fit in due to the fact that its a small form factor desktop and it uses low profile pci-e slots, most of them are almost the same price I payed for the entire PC
I read that the videocard just affects the 3d view of the toolpath and not the cutting...
Will I be ok to run with just this set up and no video card at all? Or buy like 512mb more ram to compensate?
The seperate video card requirements are basically for much older PC's, typically PII's. In the early days of Mach3, and more so with Mach2, a lot of PC's would not run Mach with integrated video. By requiring a standalone video card, it greatly reduced support issues.
Most if not all modern PC's will run Mach3 with onboard video just fine.
When dealing with any PC issues with Mach3, the easiest way to find out if they'll work is to just install Mach3 and try it.
