Hi there I tried to omission an older Ultimaker 3 I've took over from my predecessor. After many failed try outs with the existing print cores and materials I did a general maintenance. I ordered a maintenance kit and new AA & BB Print cores. I did all the maintenance steps suggested under https://support.ultimaker.com/hc/en-us/sections/360003440320-Maintenance despite the exchange of the axial Fan and the manual leveling wit the calibration card. I ordered new Printing Material Ultimaker dark grey CPE and Ultimaker natural PVA. After all that and installing the material according to the manual it tired a test print with a file from the net. The out come is very disappointing. The PVA is crumbling (and I used a new batch to make sure there's no moisture or sunlight damage). The CPE stopped printing soon, the bowden tube jumped out (the AA core is totally plugged) and the CPE was winding up outside the printers back. I used the standard setting's for this material, at least I think that. I attached the project file. CPE Temperature 240°C PVA Temperature 215°C On the picture you'll see the debris created by the PVA. The support structure in front is not properly attached to the grey ground layer. The CPE itself should be on the same height like the PVA, but it stopped due plugging very early. What else can I do? (I invested quite some working hours in that machine in I considering to light it on fire by now....) Thanks in advance Pascal UM3_3D_Printer_test_fixed_stl_3rd_gen.3mf
