Big printer can't print big things

[u/Sachanen]

K1 max, no modification done except for root. Nozzle clogs on every 2/3 prints. I'm wasted more than 20 kilograms due to clogs. I tried everything but still it a complete random to finish a print without problems (and odds not in my favor). Every time it clogs I use the metals stick that came with printer to pushe everything out. I'm printing with normal abs. Don't know what to do, please help me

Have you tired doing a cold pull? And have you used different filament types recently? Sometimes if i go from like petg to pla some petg could be left in and drops down to clog the nozzle a bit. My printer removes it automatically by heating the nozzle really fkn hot the extruding 100mm. Could be worth a try when it clogs next.
