this is my printer. ive been using it frequently since i bought it about 2 years ago so its done some miles. its been suprisingly good to me considering the price.Quote
What type of extruder ?
ive felt the motor and it doesnt feel hot to the touch.Quote
Does the motor feel like its getting too hot ?
my pressure roller(the clamp which pins the filament to the gear?) has been jerry rigged with duct tape to put it back in place. ive ordered another one but this is the situation currently. i believe it works and itsnt the cause of the issue because it is merely misaligned and the tape pulls it back.Quote
Mk8 direct drive extruders have been known for the pressure roller to come loose.
i have experienced this in the past but it was always when i was printing at 0.3 height at too fast a speed. this is now doing it at 0.2 at a moderate speed. slowing down may help but its finding out what has caused this to happen all of a sudden which i would like to do.Quote
Typically if something starts to fail after time, it's due to heating/cooling issues... you might have been living on the edge of this problem without realising it. You could try slowing down your print speed... that might improve things, or help you diagnose?

Also check the driver chips to make sure they're not getting too hot.

And check your temperature graph for changes approaching the 20 minute mark... maybe at a certain nozzle position, a wire to the heater is disconnecting or shorting out?
