How do I get my prints to come out as good as they were before the update?

Recommended Posts

I have had trouble with what I think is under extrusion with my prints since I updated Cura. My old files still print just fine but everything after the update are basically garbage. My prints are not solid and only vaguely resemble what they are supposed to be. I've tried to find the older version that worked but I'm still having trouble even getting that to work.

"5"

Yes, that's my answer to your question. No, it is not helpful, but it is the best I can do with the amount of information you supply.

I can be more helpful by asking for more details, like from what version of Cura did you upgrade (and to what version), and what printer are you using? It might even be useful to share what OS you are running on if there is an OS-specific issue with the version of Cura you are using. But without additional information, we can only guess. And my current guess is "5".

I'm going to guess he went from 2.6.2 to 2.7. I would try deleting all the old 2.6.2 profile junk and then starting up 2.7 again. Cura 2.* doesn't always upgrade gracefully. If you do this you will lose all your profiles that you saved but it's probably worth it.

For windows it's in %appdata%/cura/ - just delete everything in there and it's okay to delete the folder itself. For mac/linux... well give us more info before we give you more info.

For any platform, start Cura and go to Help -> Show Configuration folder. If you want to "reset" Cura, close Cura and empty that folder. Important: leave the folder in place, or Cura will try to reimport the settings of a previous version, and if that failed before there is no reason to think it will not fail again.

If going from 2.6 to 2.7 is indeed what initiated the problem, please check the material diameter *in the sidebar*. Set it correctly there once, and that can fix some issues. But we still don't know anything about your setup, so "5" is still my answer.

Before assembling look over the documentation again.  The latest documentation (probably about a year old?) is quite good with lots of photographs.  I've seen all kinds of mistakes where the printer could still print.  Things like aluminum plate on the wrong side of the wood (okay maybe that's impossible, lol), teflon inverted, peek part on the wrong side of the wood part and so on.  In particular think about the inner path and make sure everything is flush - for example the nozzle needs to be touching the brass tube I believe (inside the aluminum block).  And it's tricky to get the nozzle touching the brass but still flush against the aluminum (for good heat transfer).

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
