What was the printer doing before this error occurred, has the printer been in a constant printing operation or has it been standing for a while?
The error has to do with the connection between the printer and the print heads!
please upload a photo of the heads pogo’s and of the flex cable between the heads and printer
The problem appears sometimes while printing and always when printheads are purged.
The pogo flex cable is brand new. The pogo pins are clean and the springs work properly.
The timing belts are also new. When I replaced the flex cable a was able to purge the heads once.
Now it makes only few strokes and then stops.
In my experience it is a pogo pin issue. Pogo pins are clean and flex cable is new… possibly the pogo card itself might be the problem then.
I have had everything happen to mine and finally it is working. Still I decided to sell it. I am quitting 3d Printing. Good luck!
