What do you need help with?

Why does the JSON have this? "bed_pid": {"command": "M304", "params": {"P": null, "I": null, "D": null}} Send: M304 Recv: echo: M304 P180.15 I35.19 D614.93 Is what is reported via terminal?

Recv: echo:; Bed PID: Recv: echo:echo: M304 P180.15 I35.19 D614.93

The double echo here is why. None of the rest of the lines have it. It's probably a bug in the firmware you're using and should be fixed there to remove the doubling.

Looks like I will be submitting a new bug, ugh!

[cp2004]

The mentioned PR in Marlin should fix this.

I tried the change, via a patch and it works on the E5+ and it answered another question I had which was why the BED PID values were not showing up in the menu to change! Thanks!
