Scratches on the Top Cover

Postby Timon » Tue Jun 19, 2018 11:00 pm

Hello everyone,

I have recently added the guid tubes to my 3D printer after having issues with the filament snapping. Now I had a long run with these on, and it turns out they scratch the top cover of the printer. Very upsetting. Does anybody have a solution to this? I thought about pushing them further in, so they do not touch the cover anymore. Then again, if the printer head moves over to the far right, they will still touch the top cover, even if they don't if the printer head in in the origin position in the lower left corner.

Picture attached.

Cheers,
Timon

This happened to my Pro2 as well. It gets much worse than pictured here.

Unfortunately, I think preventative measures are limited to putting tape or something similar in the affected area. Otherwise you'd have to put in a radius at the top of the print head to keep the tubes from arcing upward.

We used (reused) some of the clear wrap that came on the printer to protect the top and filament door. We plan to make risers for the lid so we can remove the film, but don’t see a better solution for the filament spools & filament rubbing the door.

I designed a lid extension for this as a secondary reason:

Could you explain briefly what your part does, and how it prevents scratching the top cover?

This was another thread for the same issue. Just in case somebody else comes by and wants to know more:

This lifts the cover a few inches so the tubes don't rub on it. The rubbing oddly enough causes additional friction (very small amounts of) for the filament to be pulled by the gear, and saves the cover from being scratched.
