I just posted some pics of my Mitsumi-fied machine. I just got it wired back up and working today, about a week after receiving the goodies. I'm happy with the rigidity, clamping options, and look of it all. Very easy materials to work with.

Where did you post them? would like to see them.

thanks Will!
@criznach: nice work! BTW, Is there any particular reason behind extending Y instead of X? Given I haven't assembled anything yet, I have both options, wondering what is the best thing to do.

Thank you. I've been spending way too much time on it. :)

From what I've gathered here in the forum, doing Y first is better because it handles the extra span without much extra work. And it makes sense to me... The deflection from the gantry on the Y rails is mostly straight down, which is their stronger axis. Extending the X is harder because you've got to stiffen the dual makerslides against twisting. I really did think about doing the X because I like the open front of the machine, but decided that Y would be easier.

Thank you! Those are really good points, most certainly will be doing the Y extension.

I extended my y axis first for the exact reasons mentioned. Then when I had time later I swapped the rails and built in all of the added support to minimize deflection as a result of torque about the x axis. Even with a moderately modified system an x axis that it more than 500mm will show deflection that will cause some chattering as you cut perpendicular to it. But it is not too hard to add rigidity and it does not take any specialty parts, just some time and patients.

danimal, how did you support X? did you add more extrusions?

I found a sheet of acrylic that is the exact thickness of the channels of the makerslide, and I cut strips of it that were the same approximate depth as the channels. Then I drilled and counter sunk some holes into the makerslide in the exact center of the extrusion and used some two part screws from an IKEA desk to sandwich the two pieces together. It is still separable and I can replace a single rail if one becomes damaged, but it is super stout.

You cant really see the pieces in between the rails because it is clear, but here is a pic of the piece that I cut it from. I got it for free out of the scrap bin by the Laser cutter at the University I work for so I do not know what the actual source for acrylic this thickness.
