Printer just stops at a certain point

When u try to print the printing will stop at a certain level and it acts like it is still going through with the print but no filament is coming out. I have replaced the extruder gear with a stainless one, I have replaced tubbing. Tried different filament. I have tried three different object from different artists. Any ideas?

I have printed models before, this just started happening recently

Veja se o carretel de filamento não está com nó… talvez o filamento esteja travado no carretel.

The times this has happened to me were a clogged nozzle, factory filament diameter too large to pass through extruder/Bowden tube, filament tangled on spool, the spool dragging, or filament feeding into filament sensor at too much of an angle.

I just ordered a new hotend and tubing off amazon. I am hoping that solves my issue when I get it installed. I will check the spool and angle of the feed as well.
