Well...moving away from the Shapeoko 2...

I'm building my own MDF machine with NEMA23's and SBR16 supported linear rail. I just couldn't see how I could fix the lack of rigidity in the SO2 design. I upgraded my SO2 to 1mX1m but that was a mistake. I should have spent the money on the new design. It's such a sexy machine though and a shame I have to abandon it.

I'm going to keep the GRBL based Arduino Uno controller for my new build though. I like that setup...simple and USB connected. I will have my SO2 up for sale soon at a greatly discounted price.

Yeah, the SO2 at its original / stock size is great machine (and downright cute). Upgrading along the Y-axis isn't too bad (that's what I did w/ my SO1), w/ the ability to add side supports, but going beyond 500mm (w/ the rails doubled up and joined together) is likely the limit of Makerslide for an unsupported span for any but the lightest usage.

Yes...and I'd have my doubts about the X-Carve too.

Yeah, it's been kind of sad watching the folks on the Inventables forums work through the need to fasten the double Makerslide for the X-axis together. Still really surprised that they didn't work up a way to do that, and that they chose to offer the 1M x 1M machine, rather than capping the size at only upgrading the Y-axis.

But... Not fastening the makerslides together?
That's a necessity even on 500mm X-axis.

I expect that if you replaced the motor plates and addes another makerslide higher up, then extended the carriage to take advantage of it, it should stiffen up considerably.

I have been thinking of this too. But using furniture grade birch ply. It would be interesting to see your design, and hear how it's working out for you.
Good luck

I'm still happy with my 1000x1000 SO2 with no rogidity mods whatsoever

but then I don't usually require high precision in my projects

But I must admin when I see professional machines cut through material like butter on high speeds, i am jealous.

Just wanted to show a few pics of the new build...

Keep us posted! I like to build custom machines so it is fun for me to see others walk through the (often very long) process.

Any more pics of the xy interconnection. I am on my phone, but I couldnt twll much about it specifically.

No...I'll likely build a iron frame, then mount the long Y axis rails. I'll then design the motor mounts for that.
