I have been making some post around different parts of the forum with the same/similar problem. I am now on 2.9 firmware on the controller, but I am not sure what actually is the problem. The print stops randomly in the exact same print. I am currently only printing my Incredible Basic IKEA Bittergürka Quarter Circle Pot. These are the four first printed pots (with successful design), where one of them stopped mid print.
It should be about 11-12cm high, but the last 10ish prints have ended up stopping at between layer 3-4 to 4-5cm high (one missing a cm from being finished). It just stops, and when I go to have a look, I can see the printhead have stopped mid print and temperature on display is dropping down. Some of the time jog mode works ok, but other times I have to turn controller of and on again before its working. After thinking it was JS-software crashing that created the problem, I did the last three prints directly from the controller, but no luck. First print printed for 2-3 hours, before stopping, while the two next stopped at layer 3-4.
Collection of some of the failed attempts, with one finished (yippie-ay-kayey!) at the left.
Here its stopped and cooled down. Could seem like the controller somehow has reset the print and is just ready for a new.
Does anyone have any idea what is going wrong?
