Hello people!!
Nice to be on here! First post.

We are building a quite ambitious cnc for wood,soft metals and sheet metal.
We are at the part where we should start ordering things. But to be sure that we dont have any...mishaps. we have some questions. I will start off with a few simple ones.

We are using nema34 1600oz motors. RP drive. Table bed is 2.1*3meters Planned on using shielded wire and stranded. But what awg should it be. Motors are 7.8amps and awg 22 is rated for 7 amps. But there are quite alot of variabales to consider so what do you recommend? I think awg 16-18?

Same goes with the spindle wire. We have a 4500w vfd air cooled spindle.

An actual example of the wire would be ofcourse perfect but any advice is greatly apprecciated

Cheers!
