I have a Taz5 printer with an SE print head and a Boro glass bed. Currently running Cura 4.13.10 and have updated the latest firmware. I am getting a random problem, different projects, different filament with the filament feed stopping mid print, the printer continues to operate and finish the project. Does not appear to lose head or bed heat. The filament appears to jam as it appears that the feed dogs strip out. The filament does not appear to be jammed in the head as I can do a retract and the filament will feed back. The printer is running off of a dedicated PC running Windows 11. Have checked/changed the tension with no change in the results. Sometimes I can restart the project with the same filament/settings and get a complete model.
I have taken the head apart, cleaned the drive gears, checked for problems but can see none.
Filament appears to feed cleanly from the spool with no restrictions.
Any ideas on what else to check???

It sounds like a case of heat creep. You didn’t mention what type of filament and what temperature.
The link above will find lots of articles explaining the issue and lots of suggested solutions. Something as simple as lowering the temperature by 5 degrees can be the difference between success and failure. Also reducing the retraction distance can help.
Thanks for the response.
I think I have tried most of the recommended solutions. The printer has been a faithful workhorse for me. As tech support no longer supports the TAZ5 it was reaching the limit of its life.
I thought about replacing the head but finally decided to just buy a new printer.
