    Thanks! Hoping to have it done in the next couple weeks, but who knows how long it'll really take :)

    Great to see someone taking on a full sheet size. Will be watching with much interest.

    I wonder how well the 3d printed parts will hold under stress. Please let us now once you have the machine up and cutting wood.

    I'm expecting it will hold pretty well -- it's all PETG, 50% infill with 3 perimeters and a concerted effort to have the stress points align horizontally and transfer most of their force to the extrusions. You can hit the side of this thing with a mallet and it won't move -- I tried it :) I'm more worried that the holes I tapped in the conduit for the supports won't hold -- it's only 16 gauge steel, so that's not even 2 full threads per support, and right now I only have 5 supports. Of course I can always add more, but that'll mean partially dismantling the machine to do so.

    I'll definitely keep it up to date and let you know how it goes -- even if it doesn't go well. This is actually building on what I learned with some previous builds, and all the weaknesses I encountered before are mitigated in this design.. Hopefully there aren't too many new weaknesses!
