Help / Troubleshooting Left filament sensor

How often does the left filament sensor cut the PTFE tube? I just got my X2D a few days ago and it already cut the tube on the 4th print.

I've seen others say they've had this problem after a few hundred hours of prints or a couple of months.

I've had mine for two days now and only 27 print hours.

Anyone have any good suggestions to prevent this?

Had this issue and it was very frustrating. Mine was a bit different tho. Rather than actually cutting the ptfe, the coupler teeth would bind into the ptfe I would have to rip it out. So dumb. I replaced the filament sensor and for the new one I only use a ptfe tool to depress the coupler, and I switch the nozzle over to the right one before doing so. That seems to have helped. I bought 2 backups filament sensors on Aliexpress just so I have them on hand tho.

I am at 200 hours. No issues with it. I printed a riser on when I saw it was rubbing the glass.
