Hey!
I still have to get used to the filament dryer.
So, errors can of course happen, because of the user (me).
I believe it was something about 32% ? and at the end, it was around 10%. At least, the display was showing this. There was not a single water drop spotted, during the drying process.
I had the valve closed at the top, but there are some small holes, where you can feed the filament to the printer. The were not sealed/closed.
I understand, that a material is really moist, it lookes like trash. But, the XYZ cube looks quite good, the only problem (so far) is the under-extrusion on the top layer.
After the current print is finished, I will post the result here.
Edit: I bumbed the filament flow ration up to 1.0 and the top layer looks much better now. I will do another XYZ cube with a filament flow ratio of 1.05 and compare the results.
