How I fixed Z banding on my 12" i3v. AL Y bed and solid state heat bed relay/PID

[Carrot_or_Stick]

Here is a picture of my wiring setup. In short:

(+) from PSU goes to (+) on SSR (Labeled as 1)
(-) from SSR (labeled as 2) goes to one input on the heated bed (They do not have polarity so either is fine)
Unused wire from heated bed comes back to (-) on PSU.

That takes care of the load side.

Connect the labeled connections "3" and "4" on the other side of the SSR to your board while making sure to match the (+) and (-) correctly since the board does have polarity.

This is how I have my 12" heated bed wired up through the SSR on my Rumba board. I then ran the PID config and input the results into my config file. So far after a few prints things are good and my house hasn't burned down.

Good luck.
