No issues really, when it's too hot, I run multiple fans everywhere to keep things ventilated around the printer, and during winter for now (my garage is insulated), I just let the heater run a little longer for warmup, and the head takes a few minutes longer to warm up to optimal temp.
Output has no issues. All normal.
I get that. Mines in my un-controlled garage - in the summer its said it was too hot... I kept printing, worried I was breaking it or putting unnecessary tear on it - but I had my garage opened a crack and I blew a fan into my house on one side...and then out of the garage on the other to maximize airflow, and blow the cool house air in, it helped!
Even now in winter - it's -8 C (17F) And after 20 FT my garage says its too hot... I just pop open my house door and blow a fan from the garage to indoors....free heating.
