I used two motherboards, one is a BTT octopus motherboard, and the other is an rp2040 chip motherboard, both of which are connected to my pi through usb. Before, when only the octopus motherboard was connected, the klipper worked normally. Now I add a motherboard and start to report errors frequently. . I really don’t know where the problem is.
