Hi all - I have stripped down the hothead of the space Kossel 3D printer and it's awaiting a replacement hothead and reinsulation. This means its out of action until I can fit that replacement from next week.
After experiments heat-insulating the hot-head last night, it was still pulling more juice then it should and burning the insulation rather than improving the heat stability at tip. This is due to the hot element being a bad fit inside the head's housing, causing it to compensate with over-heating. Probably due both to overheating and lack of strain relief, the backend of the element has degraded and is exposing the 12v copper connections which is asking for a short. Since the heating element came from the supplier like that and is tightly wedged inside the Kossel's head, its better off being replaced with the old Prusa's E3D head I have at home. I'll probably switch-out some other parts too as I have better quality versions at home that I don't really use. Cheers, Nordin _______________________________________________ 57north-discuss mailing list 57north-discuss@lists.57north.co http://lists.57north.co/listinfo/57north-discuss
