I’ll start out saying, i’m not very good with this stuff… I have an Ender 5+.
I had it setup with octoprint and klipper from a guide I found a couple years ago, and it worked OK for me to get klipper installed, working on octoprint, and pressure advance tuned ok ish.

Recently my SD Card became corrupt, and like an idiot I didn’t have anything backed up.

So I’m trying to setup the system again from less than scratch and it’s kicking my ass.

I’ve decided i’d like to try Mainsail, as it’s interface looks interesting (no other reason) But I can’t for the life of me get it working.

EVERY guide I try and follow seems to fail on the connect between klipper and the printer.

I can flash the klipper firmware successfully, and have updated the port ID in the printer.cfg file, but it always comes back to klipper not being able to see/access the port.

Any help would be appreciated here.

    Found the port ID by ls /dev/serial/by-id/* I only have one usb device connected, the printer.

    I didn’t make a new line in the printer.cfg, just edited the [mcu] serial: /dev/serial/by-id/usbXXXXXXXX To match the id I found in the previous command.

      That sounds right. And “klipper” is in the XXXXXX part, right?

      How did you install klipper? Are you using mainsailos, or did you install manually? Or with KIAUH? I have an ender 3 and ender 5+, both running klipper. I used the official raspberry pi imager program to install mainsailos to both SD cards, and things went fairly smoothly.

      What error message are you seeing in mainsail? I’m wondering if klipper doesn’t have permission to access the USB device, but that seems unlikely if you are using mainsailos.
