Is a new PC needed?

[Pilsbury]

I have been happily cutting away using UCCNC with no issues. But my cuts have not been too taxing. My max time taken has been a couple of hours.

I’m now doing a bit more..... a lot more in fact. Probably not efficiently either! Basically I’ve got a predicted 72 hour cut with a 0.25mm tapered ball nose endmill with an 8% step over. Project is 800x450mm so I can only imagine the G Code running into many millions of lines!

UCCNC is properly crippled. Took over an hour to load the file, now for the last couple of hours is almost un-navigatable as any mouse click causes it to not respond for a few minutes. Basically beyond the limit of usability. As is the rest of the PC while it’s dealing with this.

The PC running it is on windows 7 64bit but is fairly low specced, 4GB ram, intel core 2 duo E7400 2.8GHz. But that seems to be well above the stated necessary specs quoted for UCCNC.

Am I asking too much? Will a better specced PC be the answer? Like what? I have an i7 overclocked with decent GPU and 16gb ram inside the house, but I’d rather keep it there! What does UCCNC need most? RAM, CPU, GPU?

Thoughts appreciated.
