You might get lucky, but it's also totally possible that your cut will be nice and flat with a beautiful surface finish—and 0.5⁰ off of square, which looks great until you assemble the frame. I agree with DD that if you are going to use the square ends as references (and it's easier and more stable to do so), ordering cut-to-length extrusions is worth it, at least for pieces that butt up square against another piece.

If you've decided to go the non-precision route with a hacksaw, one way to improve squareness of your cut is to clamp a sacrificial fence to both sides of your material and saw against the fence. I have used this technique (though not for building printer frames) and I found it quite frustrating because not only was it slower, it still wasn't as square as I wanted... ☺

I was thinking that was the likely outcome. Still, i snagged a vintage NOS Makita LS1020 off eBay, which only has single miter function (not compound), so there is only one angle to dial in. Once set, I bet it is fairly repeatable.

I've ordered Misumi in the past, and while the cuts are square, they do vary from piece to piece (+/-.5 mm). If you need two short rails to be very parallel it's probably on the limits of OK. Their higher precision option of +/-.2 wasn't when i ordered, mine came out at more than .5 different. I'd stick with the regular option and hope for the best.
