Filament cutter jammed almost every time after cutting filament. Replaced it with spare one but it didn’t help. I have to manually slide out cutter before every print. It seems there are some debris or whatever on its way.
Don’t want to disassemble extruder now because of printing urgent orders for customers.
You could have debris stuck around the cutter. Others have mentioned that sometimes one of the metal arms from the PTFE tube compression fitting (at the top of the extruder) can break off and fall down into the cutter and get stuck on the magnet. Also, the cutter itself only works when installed in the correct orientation (there is a “top” and “bottom” on the cutter), so make sure you have installed it correctly so that it can be pushed in and then have the magnet in the extruder automatically push it back out.

If you clear the jam and still have a cutting problem see the post below with a fix by @KGS_Engineering.

Cutter orientation is correct, double checked.
Maybe debris from fitting is the correct reason, have to check it later.
Thank you for your advices.
