General Mach Discussion / Re: cnc router work

it's mostly about time. I've been a bit busy with other things. I will at some point get a proper router setup, then I'll start having problems.

I'm looking to have small carbon composite parts trimmed, 2 different designs they're about 9x10x1.5 cm overall and the material thickness is 1mm. It would be an initial run of 30-40 pairs.

Could I accomplish this with open source/trial software? I got the mach3 but I'm still a bit confused from some of the comments about software requirements.

let me clearify the dimmensions. The laminate is 1mm thick and the contours make the part about .75 in thick.

the parts are approx 3x3in 1mm thick. there are 2 different designs and will probably run 100-200 of each to start, up to 10 at a time. all straight lines and radii. will need simultaneous 3 axis movement. models are in iges so all pretrimmed (except fringe) and trimmed dimmensions are known. will be making an hdpe jig with flat rectangular cuts to hold the pretrimmed parts. the likely bit would be 1/16 by 1/4 cutting surface.

how do I upload pics of the pretrimmed and trimmed parts?

thank you so much for the much needed help, I think I hit all the questions, i'll see if i missed any.

I'm completely new, never touched a cnc machine. I'll be getting a starter cnc router, it would be from moosecreeksales on ebay. The job I'm looking to accomplish is trimming small fiberglass parts that have a 3d trim path, the bit can stay vertical. My question is, what would roughly be involved in programming a 3d path? I have a solid model of the part and can read the profile manualy. Unless there's an easier automated way to go from a solid model.
