I had by now 3 „Toolhead lost connection ….“ (No 1, 3, 4 and Th 3 wasn‘t even involved in this print) 1 „Th 1 temperature abnormally - check termistor cables“ and 2 others (one was 0003-0522-0000-0002) witch required „power off - check cables - power on - resume print. There wasn‘t anything to check but the prints resumed. As you can‘t reboot the printer remotely it is stepping on my nerves.
And the next “TH1 lost connection to MCU”! Before I could react, the build plate with PETG had cooled down, and the resume function pushed the objects around. I’m slowly losing my patience.
And while I was creating the ticket, I got “TH2 lost connection” again…
When did you assemble the printer, or, have the toolheads been performing well before ? Can you double check the usb cable connections, i.e. are they sitting firmly in that USB-C Slot ?
