Mungee's All-Steel CNC Build Thread
Hello everyone!
This is my first post as well as my first build. I'm looking forward to getting this machine started and hoping that all of you can help point me in the right direction.
I'm in the planning stages of building a 4' x 8' cnc router made (almost) completely from steel. I've been reading threads here for about a month now, and I've decided on a design that borrows from several different builds I've read about. Here is a mock up of what the machine is gong to look like. I was going to include the .skp file, but I can't seem to get it to upload. I'll upload it to a file sharing site and include a link later.

All the steel is going to be 0.250 wall including the riser plates and braces. The x-axis rails are going to be 2" x 3" with a 0.250" x 3" plate as the rail; the cross pieces, legs and supports will be 2" x 2"; the y-axis will 3" x 4" with a 0.250" x 5" plate as the rail; and the z-axis with be 1530 with a 0.250" x 4" plate as the rail. The table bed and the gantry are going to be welded, and the legs and supports will bolt on.
I'm sure that most of you realize by the design that this is an R&P based router and I plan on using mostly "cncrouterparts" components. I'm going to opt for the nema 34 motors because of the weight of the gantry and this machine is going to be used a lot.
I've done deflection calculations and I think the design is good but I'm interested in anyone's opinion. As soon as I take possession (Oct 1) of my new unit, I'll be getting started on the build.
Please let me know what you think.
Thanks,
Mungee.
