Having had a couple of bad prints, where the left hand edge of the print kept lifting and fouling the print heads, is there a practical limit on room temperature for printing. I currently use my printer in a conservatory, where the temperature is often below 20 degrees C, and the machine will "cold-soak" to that level overnight. The problem has only just reared its head as the OAT has started to drop, as Autumn sets in, and I wondered if anyone else had experienced similar problems.
One thing that I had noticed was that the nozzles would heat up to 220, for ABS, but when the print started the temp dropped to 218/219 as the print progressed, as though the temperature of the filament was dragging the nozzle temp down.

Any ideas or thoughts?
