Hello, after many months planning this I’m so close to building my CNC and have opted for the SLB-EXT as my controller.

I’m using 4 Closed Loop Steppers with limit switches all all accesses incl both Ys

I forgot to order the drivers initially, but now arrived and i’m at the point of connection, avoiding risk at this point, can someone take a look at my drawing and tell me if I’ve made any mistakes.

Any guidance would be truly appreciated.
