Thanks for the reply Pete.

To summarize my points below: This is meant to be a redesign based on a pre-existing BOM/design, which was originally built to a price (if I understand the scope of the...

Thanks for the feedback. I will try to address each of your points.

1) Yes, this design is still in the early stages, but I was looking for feedback on the mechanical rigidity of the basic...

I posted a while back and got some great feedback (Thanks Peteeng), and finally decided that the PrintNC would be the best design for me. However, after much investigation, decisions on required...

Thanks for all the feedback Peter. I'll try and address the points that you brought up in chronological order:

After reviewing the theoretical deflection of aluminum extrusion vs steel tube...

Hi Peter,

Thanks for those documents. Steel tubing is definitely a construction material that I've considered versus aluminum extrusion, but not aluminum tubing only because of convenience. How...

Thanks Peter. That's a beautiful machine. I'm only halfway through the thread, but at least I know what kind of stiffness I need if aluminum extrusion is used. My local supplier has 3" x 3"...

Hi Peter, thanks for the reply. My current design goals are to cut through aluminum sheet/plate up to 0.25" thick, but eventually cut through thicker bar stock to make functional parts. The cutting...

Apologies if this thread seems redundant, but I wasn't able to find a thread on a suitably similar design.

I have a mechanical background, but very limited exposure to CNC mills/routers. I have...
