Hi all,
I've been having issues with my new ultimaker 2 go since it arrived. I think I have pinpointed the problem to be heat creep but don't really know how to proceed.
I'm using:
- Ultimaker silver metalic pla
- 200 degrees print temperature
- 40mm/s print speed
Last night my print failed halfway and after a few searches this seems to be an indication of heat creep. The air in the nozzle as seen in the atomic pulls supports this.
In the first week I already experienced these problems and replaced the heat block, nozzle and ptfe coupler. Two weeks later the ptfe coupler looks just as bad as the one I replaced.
The fan that cools the heatsink appears to work fine and switches on as soon as the temperature reaches 40 degrees. It is also clean and not obstructed. When holding my hand near it however I don't feel any air blowing so I suspect it might not be powerful enough. It is however the fan that the printer shipped with so I expect that it should work.
If anyone can point me in the right direction that would be greatly appreciated!
