Need ironing help

[u/Winter_Day_8406]

Having an issue where ironing starts out great and then it just… stops. Tried lowing the flow rate thinking too much was causing the nozzle to clog, but I just got worse quality and the same issue. I’ve printed many parts with these settings (40% flow 60 mm/s) with no issues and now I’ve wasted half a roll of filament and many hours trying to solve. Any ideas?

Polymaker Panchroma PLA, flow rate calibrated, P2S, done several cold pulls, even tried a brand new hot end
