Dear Support Team,
I have my M200 since 2days... it was already blocked: I discovered (unfortunately too lately) kind of really little pieces of wood or paper in the extruder motor hole and that was traped by the very first filament I put inside... Thus, I had some burnt dust into my noozle, making bad black drips everywhere until it definitely blocked printing.
I had to follow the hotend replacement tutorial (http://support.zortrax.com/hc/en-us/articles/200986731-Hotend-Replacement-) to clean all the path.
I was surprised not to have any yellow signal cable to unscrew. Is it normal ? is it a v4 feature to prevent from damage while dismounting ?
Thanks, Regards.
