This thing is driving me bonkers!
Does anybody have experience using this printer?
I have the original version of the firmware (Version 2.2.0.) installed.
My problem is the the well-known loud knocking sound from the feeder mechanism on the left. I have made many attempt to clean the nozzle, using both the very fine wire and the larger pointed rod.
It seems to me that the head temperature is slightly too low (the machine reports 189 deg C) for the black PLA shipped with the machine. A brand new (sealed) reel exhibits the same problem.
The XYZ slicer has an option to increase the temperature by up to 10 deg C, but the firmware is too old and does not support this function (according to the slicer's user interface).
I do not want to update the firmware at this time ...
