Yes, I suppose that is kinda funny 😛 The stuff works like a charm but I guess it's just a little too aggresive for us overprotected europeans. I also cleaned up my core with a heat gun first but couldn't get rid of the burnt bits. This stuff did. 😛

I've used Euro-Claddings Quick Paint Remover to soften up PLA (as a last resort). I believe it's banned in the EU. You might try something similar like Bardahl Gasget and Paint Stripper.

Another tip when your ABS print still starts wobbling and being dragged arround by the printhead: Print a brim arround it and once the printer has printed that, tape it to the bed (pause printing if necessary).

I've recreated the problem in an example, in case anyone is interested. FusionFilletProblem.zip

Correct. That print failed. I changed support to everywhere and it printed ok. 💩😃

Couldn't get the fillet working in FreeCAD itself.

Yay, that works, thanks! For some reason the fillet on the base I created in the Part Design workbench got lost, though. Recreating it in the Part workbench fixed it.

OK, I'll try that. Thanks for the link! 👍

Thanks for your explanation. I'm using FreeCAD for moddeling. I guess I'll have to somehow clip the cylinders with the torus...But that's beyond the scope of this forum.

I have a model that looks right in the preview of Cura. When printed, it turned into a mess and here's why: Left a screenshot of Cura, The right one a slice off of http://gcode.ws/ Am I missing something?

Curling at the corners is often due to the printer head being too far off the bed. Pretty sure Crusty's right. 🙂 I.e., calibrate your print-bed.

Found what I was looking for: Euro-Claddings Quick Paint Remover does the job. Banned in the EU, fortunally I still have a bunch of cans laying arround. 😄 Grtz., Alex.

Had a bit of a leakage of PLA over the hot-end of my UMO+. Cleaned up most of it with a hot air gun, but the temp. sending unit and heater element are still covered with a thin layer of PLA and I can't get them back into the hot-end. Any way of maybe dissolving PLA, or any other means of removing it without damaging anything? Grtz, Alex

It looks like we have the same problem: Try running it in Windows 8 Compatibility Mode.

This is odd: I can stsrt Cura as soon as I've installed it. Sometimes after closing it, I can open it again as usual. But more often the interface won't come up and Cura will just sit as a task in the taskmanager. Reinstalling Cura helps once, but the problem reoccures. Running it in Windows 8 Compatibility Mode works, but that's not my favorite solution...

Ahaa! I found the culprit. You were (almost) right: There was short in the heater element of the print head (not the heated bed). Fixed it and it's merrily printing away again. 🙂 Thanks!

Here's a little video of what's happening: https://youtu.be/N1u-zWsm9f0

Tried this but it didnt solve the problem. Mind you, in my case the bed heats fine and the servos work as well. Any other ideas? (anyone 😀)

Thanks for the quick reply. I'll try this tomorrow.

As soon as the printer gets to start heating the printhead (either through starting a print, or going to "prepare=>preheat PLA1") the relay klicks off and then on again. I've had problems with the connection of the adapter to the printer being a little too loose ever since I've had it, but this seems to be a permanent problem. NB. Not quite new here. Used to be Alex+
