Odd error cropped up tonight. I noticed in the communications window that "cold extrusion prevented" was being reported many, many times (I'm 16hrs into a print).
The odd thing is the print hasn't failed, the printed does seem to pause for a second at intervals (I'm using USB) but then it goes merrily along as if nothing happened. The temperature graph shows the extruder and bed at a nice constant temperature.
I haven't upgraded to 4.1 yet, so it's not related to the new patch.
Any insight would be greatly appreciated.
