Cnc? Anyone got one?

Man, someone posted an awesome CNC build here a couple years ago. Can’t remember who it was, so not sure if they are still active...

Well I would offer but I'm not sure if I know how to use my little hobby CNC that well yet (or have the tools) to do things like what you want. I mainly used it to drill holes in circuit boards. What is the material you want to cut and how thick will it be?

Acrylic, Probably 3/8.. Thats my goal but depends on what I can find in scraps

I'm open to design changes for the cutouts but I just want to maximize the holes to allow for the most flow through.

I could drill it but would take forever I think

I would recommend holes or slots rather than what you show. Your design would be very difficult and time consuming on a CNC and would probably clog the bits up.

Holes would be easier the bit would have to be round in some form to begin with. Maybe holes that stretch in a line i.e. slots would be easier. I'm have some .22" sheet acrylic I could use. It might take me a while to figure it out and I recovering from a cold this weekend.

Yeah figured the round part. How wide of a bit can you use? Now that I keep thinking about it. Maybe doing diagonal lines across. The whole thing. Hmm.

I think I need thicker than.. .22. 1/4 in would be bare minimum and even then I'm shying away from that.

Hmm making me think.

I'm thinking the bit could be up to 1/4 inch but not certain of course it could cut something wider than that if it cut through the material.

My problem with this CNC is I didn't anticipate getting some software to script the tool paths wasn't cheap and/or the free stuff out there wouldn't work too well if at all. However, I haven't really looked around lately. Lucky my PCB tool outputs the tool paths for drilling with some minor modifications to make it work right and that's mainly what I have used it for.

I did find this easel tool that they made later on that I haven't tried out much yet, but I think you can share the design with me later if you put something together. The only other problem is I checked my machine and it's only good for a bout 12 inches square. So you have to split it up somehow if that were possible. :(

I appreciate it but I really need it this size to fit properly and hopefully give me the flow I want. This is going to be a diy roller mat plate

Yeah sorry about that. Hopefully someone else will have a bigger CNC.. I could in theory make the unit bigger it but I not sure if they have the kit for it anymore.
