CNC Router V1.0 (For Cutting Multiple Materials)

[JAZZCNC]

Hmm maybe it's time for yet another re-think then...

I don't want to go OTT with the design but obviously it needs to be useful. What are you opinions on the gantry design as it stands so far? Are there any other alternatives to a steel box section base?

Thanks for all the help,

Dave

Dave don't get me wrong I'm not saying profile won't work because it works great and I use it all the time but it does need to be supported and braced correctly and by this I mean not using in the normal manner profile is used IE: using corner brackets etc. I'm also not saying your design is flimsy or weak just not has strong as you may be thinking. It will certainly have some chatter in harder materials as the frame vibrates.
For this high side design to work best with profile, esp when on it's thin edge you need to brace the hell out of it using plates.

Your gantry is ok-ish but I would have a bit more strength in the bottom profile as this takes the most the cutting forces. To be honest I'd have the L shape layout of the profile at the bottom but with lower profile laid flat.

I understand your reluctance to weld but it really isn't difficult or needs to be expensive. Don't need a Mig and like as been said cheap stick will work fine.
If you don't want to weld then how about finding someone who can weld and have them do it for you.? If you cut and preped all the steel it wouldn't take someone long to weld that simple frame.! . . 2 hours Max and I'm allowing for a very very slow welder there.!! If all steel was cut and preped it would literially take me 30-40mins tops just for the welding.
