Squaring up my Y-Axis on power-up

[PaulK.Mckneely]

I have an upgrade that keeps your X and Y axes square.

Getting X-axis perpendicular to Y-axis

JustinC, I recently bought a 1000mm X-Carve but I saw that this loss of square between X & Y was going to be a problem. I wanted more clearance and I also wanted to only use 3 steppers instead of four so that I could use the same Arduino Uno /w g-Shield that is on all of my other machines. This simplifies tuning current and reduces the requirements of my power supply because using only one motor for the Y makes it equivalent to the X. So I developed an upgrade kit using a shaft to run from one …
