[Trapezoid Square Parallelogram] [Measure diagonal of a square] I’m on day 2 of CNC setup and I just discovered something that I do not recall seeing on this forum so I thought I’d share. I mounted my machine per the instructions in the manual and YouTube video and it seemed to go well. Everythi…

I adopted this approach for squaring the machine with an old pair of calipers now dedicated for this verifying square from time to time. It removes any error induced by the alignment of the feet (twist) or Y rails that are different lengths etc. [Squaring a CNC Gantry Machine with Simple T…

Wait, I was told I wouldn’t need to use math any longer…

Moooooooore math. Always more math.

A two-sided piece was when I figured out I was out of square :grimacing:

While wrestling with how to get my parallelogram X-50 square (and the MANY possible challenges), I think I will attach the feet to aluminum (or possibly wood) plates that can somehow move for adjustment if necessary. I’ll have to figure out how to accomplish that, but I think it’s doable. This will …

Hi @DainBramage1 Not sure if you’ve seen this post of an all aluminum table , but you could use small pieces of this aluminum extrusion or entire rails of it for each Y-rail. Cheers to square and coplanar machines!

I did it out of what I had, which was wood! Works pretty well!

Another thing to consider is it could be a trapezoid or otherwise. See diagram. Left is correct, right is not and can cause Y rails to bind. [Square-vs-Parallelogram-2]

I’m using the older controller and there is no calibration for X and Y. But, if you can calibrate for linear distance then why not just add a calibration routine for squareness too!!! Getting these machines perfectly square is a pain in the BUTT!
