Cube 3D printer discussion / Repairing and Upgrading Cube Gen2
« on: April 26, 2016, 06:06:59 am »
FINALLY,
After hours of struggling I find a pretty cool community to help me!

So I was given a broken Cube Gen2 by a very frustrated friend of mine.
Quickly found the problem:
  1. The cooling fan broke on the head
  2. This lead to the heat fuse blowing.

Easy fix - bridge the fuse and ignore the broken fan.
Ha, quickly found out print jobs longer than 3min tend to jam and fail.

I had another friend print me brackets for some old GPU fans I had lying around and fixed the cooling problem.
See the fan mod pics.

Anxious I set a 1hr print job to start (40mm tall model) with some rather tiny details.
Now I do realise that the model I used was a little too detailed for this printer, but to my horror I discovered this attached hot mess after the job was done.

Back to google we go and I see that people have started designing fan ducts to cool the material as it is extruded from the device.

So here is where I am at:
I think I'll print a whole new enclosure for the printer, open air, two 40mm fans keeping the feeding ramp cooled with an added 40mm fan that feeds through a funnel to the extruder tip.

Has anyone had any similar experience with the feed ramp getting too hot and jamming and/or making a duct fan to cool round the extruder?
