Printing again...

Finally after a more then a week I got  the "light".    The printers temperature sensor was giving wrong information. There was no display of the sensor temperature rising although the nozzle became very hot....  Also the software after some time began to be unstable so I had to shut it down.

What could it be?    Today finally I saw that a little connector was loose. And I noticed that I haven't seen the blue led light on when the printhead was heating up.   It is on top op the print head.  I connected it again....and everything worked fine.....   I believe this happened as I was fiddling around with the bowden tube before and after the Atomic Nozzle Clearing.

I printed the small  plus-sign and it came out well.  Printtime 29 minutes..
