"Origami" CNC Plasma Build - folding 1200 x 600mm cut area

Looks good but from my experience I would swap the striker plate position with the switch position. I had no end of issues with reliable wiring when the switch was allowed to move...

Rod - hmmm might need some more explanation.  Unless I am missing it I'm sure the Z limit switch is non moving and for the floating switch it has to move.

I did deliberately swap the rail/truck positioning around.  The truck is now the fixed mounting point and the rail is on the moving part. Essentially a linear rail version of Tommy's linear rod concept.

Sounds like I was the one missing something!

Initial concept for torch breakaway.  I'm still working on dimensions and need to check what magnet sizes I can source which will influence the ball bearing sizes etc etc.

This isn't a new design and its concept is based on a design SeanP over on Spider Plasma created.

Anyway, thought I would post what I had at this point.

I like it!

Been working on the torch holder and a way to index it vertical, 30deg and 45deg.  The off verticals are to allow a 60deg or 90deg incl angle bevel to cut for welding purposes.

Here are some design screen shots:

I think I might have a had a brain wave or brain fart. Will work on an idea and post it but I "think" I can simplify this and get easier reposioning for bevel cust.

The limit switch looks bullet proof now.

Looking good!

I wonder how useful the fillet feature would be? Lets say you were cutting an end cap to weld onto a tube or square section.
How many setups would you have and how would you manage them?

If its not an end cap, there are plenty of ways to design a part to be welded without a fillet once you have a CNC plasma cutter at your disposal. eg. tab and slot construction. You can even cut the tabs shorter than the material thickness and weld from the back for a nice clean finish with no visible welds.
