Just getting started, after browsing here for years, and a few false starts, the time has come.

After seeing Fine Line Automations 2' x 3' build, and talking to Ahren at cncrouter parts a bit, I started ordering bits and pieces.

My goat is a cut area of at least 24" x 80" as I'll mostly be using this to cut molds for model airplanes. Figuring for most everything I'll do, this is the general 'needed' cut size.

Another consideration is limited space. I'll actually be adding on to my little work shed to make room for this.

Because of the longer X axis need, I am going with Ahren's new rack and pinion drive (one on each side). Based on the video's of his system in operation:

I am working on drawing up a system where the rails will have supportive legs like his demo, and the Y axis will ride right on top of the x, with the Z dipping down. Seem's a lot less complex considering I'm basing it around his R&P for the X.

I have my G540 as well as steppers, and some pieces coming, but need input on what might be the 'bad' part of such a design... and once I have it tweaked out, it will be time to order the 8020 and remaining bits from Ahren.

This is just an initial drawing to give an idea, remember there will be legs on the x axis's...
