Does anyone have a way to get support to respond in a reasonable time? Ive been back and forth with them for 6 weeks. I have a K2 that will not print multi color. The CFS tries to push the filament, but the extruder will not take it up. No, this is not a clogged nozzle or a clogged filament buffer. The printer prints just fine from the side spool. The filament buffer passes filament easily. The extruder extrudes fine, it acknowledges when it runs out of filament and with a manual change from the side it extrudes and picks up just fine. Any help would be appreciated. 6 weeks, and there are days between responses. Then the response is just look at these articles, are you sure its not clogged?. Ugh. Link to a 14 minute video showing the whole process and where it fails. https://photos.app.goo.gl/jj7j6CMQCUoac9539 Please help!
