Requesting some feedback on steel frame design.

your bracing can be much smaller , as the forces are compression and tension
also try brace into the very corners as this maximize's the strength of the brace , and makes welding easier as there will be even less warp

just a comment :D

Looking better but I'm not a fan of ballscrews being up above the rails due to being easy to damage thru leaning on or when loading material etc.

Also if those black things connected to the screws are steppers and your thinking to mount them like that then your in for massive troubles.?
Try to build in some adjustment for things like ballscrews to ease alignment.

You are correct, they are 280oz Nema23 steppers. I will change the mount for the steppers to something more "traditional". Is there ready made adjustable ball screw mounts or is this simply achieved by drilling oversized holes for a simple mount?

The bearing spacing isn't too critical when using twin screws so your size will be fine if it fits better. Thou more won't hurt if possible.

Okay, ill keep it as is for now then.

This makes sense, I will lower the dimensions where possible but since Im forced to buy the steel in sections of 6 meters, so I will change what i can to lower dimensions.

Do you mean like this?


I was under the impression that this approach would distort the joint more as that small section is subjected to more heat and will also have more weld material causing contraction?
