3D Printing

I’ve been having trouble with my Ender 3. I recently built an enclosure with a heater and installed a new microswiss hottend. Also It has a direct drive extruder. It used to be that I could start a print and walk away, when the buzzer went off I could come back and the prints would be well done. I printed carbon fiber TPU with the enclosure heated to 65c. The prints looked great. but after all the cleanup, it prints stringy, some times at the start and some times in the middle… I’m thinking that Ive toasted the steppers or the motherboard. Anyhow, all the info I get about testing steppers is about Ohming out the phase coils, and I get good reading from that.
Creality steppers run hot anyhow, and my rational says they’re toasted.
I’m tearing it down and re-assembling it before I try printing any more, I’m just looking for suggestions/ directions and ideas as for what to do… and yes I’ve leveled the bed and adjusted my Z offset and adjusted my extruder steps/mm. It printed three good pieces and went south again…
