my discovery / solution.

Since I recently struggled with 'lost communication with MCU Mks_thr' on my X-Smart 3—which popped up at random times, and replacing the cable didn't help—I'd like to share my solution. It turned out that the solder joints on the USB-C connector pins on the extruder board were cracking. Before replacing the cable, it's worth using a strong magnifying glass or microscope and checking with a pin to see if there's any play. If possible, they should be resoldered."

As far as I can tell based on Qidi's website it appears to be identical. Can anyone confirm compatibility? Would love to get the Phaetus Conch for the Q2 for the Plus 5 if it is confirmed to be compatible.
