Printers fighting for control

General Discussion

Basic Information:

Printer Model: 2 ender 3
MCU / Printerboard:mini skr 3.0
Host / SBC cb1
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

…im trying to run both printers off of one host a cb1 and when i restart on the other turn it off the cb1
klippy (2).log (1.3 MB)

You only can run/control one printer with a single host instance.

If you want to run/control two printers, you need either another SBC or another instance of Klipper on an existing SBC. But I don’t know if that is possible with the CB1.

As indicated by @EddyMI3D, you will need two separate instances of Klipper and Moonraker. KIAUH can set this up for you.

In addition, you need to switch to specifying the serial connection “by-path” because the Ender boards use an invariant “by-id” designation, which will cause collisions. Obtain this with:

ls /dev/serial/by-path/*
