I did a 30 minute print with 120 deg plate and 65 deg chamber after which, one cutter pin became misaligned leading to “failed to cut the filament” error. Before this, the printer did hundreds of cuts no problem (printing PLA).
I used this wiki article - the “quick repair” did not work so i had to disassemble the cutter pin assembly and realign.

Perhaps this has to do with differential thermal expansion or something. Has anyone else had this issue?
Same issue here:
