Hi, our printer was running fine till the start of this week. as seen with the image attached the printing ends up like a bird nest. we've gone through trouble shooting. but haven't found a solution. does any one have an idea of whats causing this.

Hi and welcome to the forums!

Hm, the print sure looks bad. Did you check (and how) that the nozzle is not partially clogged? Also make sure the filament is still fine. If it was stored incorrectly, it could have deformed.

If possible, post your print settings too.

we've de-clogged and changed the nozzle and that hasn't made a difference. the bed temperature is 60 and nozzle is around 220 celcius. The reel looks fine.

PTFE coupler!

Bet you a beer.

If everything has been working great for a long time and you haven't changed anything (including filament brand) then it might be that pesky PTFE coupler. It is the hardest thing to inspect, so it is always the last.
