How can I connect to the printer via a Serial Connection?

I’d like to use something like Octoprint/Pronterface to connect to my new Ace. I’m not sure how I’d go about this. I’ve tried connecting to the USB-OTG port and neither Linux nor Windows sets up a Serial connection.

Do I need to get a four-pin to serial to USB adapter to be plugged in to the Serial port on the board?

It’s running Klipper out of the box, so you can just access http://[printer-ip-address]/ to see the Mailsail UI (very approximately: Octoprint, but built from the ground up for Klipper).

You can also run an interface of your own on another that accesses to Moonraker API (which handles actually talking to Klipper… Mainsail is just a thin shell) on http://[printer-ip-address]:7125/. IIRC, Fluidd is the other major alternative interface to Mainsail. (Honestly, there’s not really a need to do for normal use, though. Just use the built-in Mainsail on the printer SoC. I have just been playing around with a separate Mainsail install for easier remote access. Technically I could probably run the ARM Tailscale binary on the printer itself, but I kinda want to keep it clsoe to stock.)

Thanks, bcat, for a wealth of information!

I had looked at tthe Mainsail setup but, following a guide, it wasn’t doing what I expected. Turns out I was looking at an old guide that was setup with a Marlin backend.

Learning more everyday.

Appreciated!
