Brand new to LinuxCNC and mesa boards. I just ordered a 7i76e board and I am going to upgrade my current setup from mach3 and a cheap Novusun NVUM controller to Linux CNC and a 7i76e. Below is my current setup minus my Huanyang VFD for my 2.2 kw spindle. I am assuming I can power the 7i76e board off of my 24V power supply? Are there any wiring diagrams out there? If anyone could help me out that would be great!

Download the pdf attached to the first post.


Looking at the power section of that pdf, do I connect just one of those terminals to my power supply? If so, which one do I choose?

You need to power both sets of terminals with 24V I suggest you download the 7i76e manual as well.
