Hi!
I have a reoccuring problem with multiple of my S5 printers. At first, it seemed that the core was clogged, no material extruded. After cleaning the same problem occured. I checked the feeder and feeder tension. During the material change, material extrudes normally trough the nozzle, but with the first layer, lines get thinner and thinner until no material extrudes and a notification for 'material empty' pops up. It seems that the feeder tries to 'jam' the material into the print core what results in a thickened wire (which makes it harder to pull it out of the core or to change material.
Does anyone experienced similar problems and/or know a solution to this problem?
