I’m eagerly waiting the LRv4 release to get started printing out parts and putting it together. While I wait, I’m trying to figure out how to fit a full sheet CNC into my pretty-small workshop. One thing I was considering was building the parametric torsion box here on the forums, and mounting it to my wall like a Murphy bed.
This is a very rough sketch of what I’m considering:
. The frame would obviously be screwed into studs in the wall. In my head this would mean that the table is supported by the hinged leg + wall studs in the down position.
I have a couple of questions to start:
Is there some reason this is a terrible idea that I haven’t thought of yet?
What should I use to hinge the table to the frame
Has anyone done something like this that I could look at?
There was someone who did this with his LR3 but I can’t find the thread any more. He did exactly what you want to do. Maybe someone else can find it or remembers it.
You saw with the other example, but recall that your table will need more space than the cutting area. Roughly budget on a foot extra, so a 5’ wide table. If you put that up against an 8’ wall as you have diagrammed there, folded out it will be 3’ high.
I’ve said before that I believe ergonomics are important. Working bent over too much leads to unsafe practices. Maybe this doesn’t apply to everyone, but bent over a 3’ tall machine is going to hurt after a while. I’ll start taking shortcuts to spend less time over the machine and I can see bad things™ happening.
A cantilever can help raise the table, so the bottom edge can be lower when stowed, but still raised to a reasonable working heigjt when out.
It would mean you could probably leave the cnc on the table and pull it up. Then lower the cnc when needed and maybe lower it on a couple of saw horses for stability.
No clue if anyone has tried this and if it works, just crossed my mind and thought I would share
I just saw someone doing this with something for his truck. Pretty good idea. And you’d definitely need the sawhorses. But I did eyeball this solution before for my Primo that serves as a plotter.
That’s interesting, I was thinking of doing something similar. My thought was to mount the tables to rails. The edge closest to the wall would move up the rails and the outer edge would be secured below. The work surface would be facing out.
