I forgot about the 800x600. We have windows scaling set up to stretch and fill a nice 1920x1080 fhd touch screen. Had to find some creative solutions to allow our security software and policies to work.

More power, current hardware, better experience, less money. Doesn’t sound possible.

Same thing with retail POS terminals. Old weak system , out of date software , no security updates, limited support response. Yet it’s must be secure and isolated… maybe it needs to be isolated because they know it’s not secure on its own…

I would make sure your fan is moving sufficient air. Maybe the bushing is wearing down and it’s running slower.

Looks like your heat break unscrews from the heatsink, maybe some fresh thermal paste to help the transfer. Some types can turn into insulators if over heated too much.

The clogging I had was a result of creep because I was turning off the machine before the cooling fans could finish bringing the temps down. After the fans were off the heat would move up and swell the filament. After I started leaving it on longer and not using emergency stop for print failures my clogging went away.
