Extrusion stops mid-print after printing too cold

I had some issues with stringing and tried to print at the coldest temperate that the filament allowed. I'm using PLA and usually print at 215C, but for this print I tried 190C. During this print, I suddenly heard a click in the extruder and then no more filament came out of the hotend. Also I noticed that the extruder gear was grinding the filament. After this, I've been having the same issue even at 215C. Things I tried (from this page):

- Adjust the pulley screw

- Cold pulls to clear any clogs

- Open up the hotend and check the PTFE tube (looked good)

- Open up the extruder and clean the gears

I also tried a different filament. Unfortunately none of the above resolved the issue. On any print I try, at some point the extruder clicks and the filament stops moving.

Does anyone have an idea what else I could try? Any help would be very much appreciated!

Thank you very much Diem! I'll give this a try.

Dry your filament then carefully readjust the idler screw until the clicking stops.

Cheerio,

Dobble check the nozzle for clogs first again and clean it if necessary. Heat it to 260°C and try with the nozzle needle. The clean nozzle is the must. Any residual filament will result in repeating clog.

Do not under heat the nozzle.

Thank for for the advice, Zoltan!

Drying the filament and adjusting the idler, as suggested by Diem, mitigated the issue a little, a did not solve it. I did several more cold pulls to make sure the nozzle was clean, but the issue still persisted. The thing that eventually did the trick was to disassemble the hotend again and push up the heater block, as explained in "Disassembling the hotend" here. The first time I had opened the hotend I skipped this step, which I now realize was crucial.

Again, thank you both for the help!
