Hi
I har several times experienced clogged nozzle, printing with for example Matteforge PLA filament, specially when I print large objects.
My setting is 60 on bed and 210 on nozzle, layer hight 0,2mm on a Raise3D N2.
I experienced that even if Matteforge is PLA filament, it separetes layers in the corners, when I print a big box object.
That is normally something ABS filament do, so I think I print the object with a closed lid, so the environment temperature inside will raise.
When I close the top lid, the temperature goes to about 40 degree celcius inside the printer after a couple of hours, but then my nozzle glog..
With open lid, I can print the object, but then the layers separate in some corners.....
I read about clogged nozzle several places in this forum, and some suggested that it was the high temperate of the extruder that soften the material before the nozzle.
I also tried to lower the current to extruder steppers, to minimize temperature raise in extruder block. Still same problem....
I have also read a lot about that the Bondtech dual extruder for Raise3D N2 would help on this problem, so I ordered and installed a dual Bondtech extruder. I changed the step count for extruder and lowered the stepper current as instructed from Bondtech. Still the same problem with closed lid.....
I also changed the fan around the hotend, so the coldend should get more cooled now.
I made a fan scout that only put air to the coldend, and mounted fans with higher airflow. I made separate fan for cooling the print object.
I cannot understand that I cannot print objects with closed lid/top, what can be the reason?
I have not tried to print larger object with for example ABS, here the lid must be closed, but I guess this will fail as well.

Hi Ken,
I've got the same problem with my N2 plus + Bondtech Extruder.
I tried the same modes an the printer still clogged with other material than Raise Filament (PLA).
Did you find a solution in the meantime ?
