What kind of 3D toolpaths are you using? The older ones or the new ones?I am currently running a 4 hour and 20 minute cycle part in my Brother. Unfortunately, that's for one part. It's a copper part that is like 98% 3D surfacing. I had planned on making a "4-up" tombstone for it, but the calculations for the toolpaths take like 3 days even when programming just one part - so I haven't had time to go from one part to four. I have a pretty good computer and before I had my own shop I was a mold maker.
I'm programming a lot of 3d surfacing in Mastercam (we're doing a lot of molds) and if it takes more than 15 mins it's pretty long. And my Computer has a 10 year old i7 CPU, so not exactly cutting edge tech.
