I’ve owned two Shapeoko 2 units, and my biggest gripes about them were the amount of twist that can occur on the y-axis, and the amount of deflection that can happen on the x-axis as the z comes down and the bit plunges into the work surface. Have your design changes improved this rigidity?
Also, I may have missed it, but I don’t see instructions for aligning/squaring the makerslide(s) when assembling the gantry. That’s a bit tricky to do so it’d be awesome to see it done in video.
