Changing anything causes problems

Howdy all

I've a problem that I hope has an easy solution. I began my 3d printing life using a modified version of Cura that came with my FLSun Q5. After a while, the fact that the Move, Scale, Rotate and Mirror buttons blocked my current layer number started to bother me so I downloaded an official copy of Cura. Fresh from the install not only did it work great, my parts printed much faster! I loved it. Now I just had to modify it to my needs. I changed some settings and suddenly it ran like garbage. I figured I did something wrong so I changed some things back. Still garbage. I changed everything back to start over. Garbage. I uninstalled and reinstalled. It worked great again. I changed one thing; garbage. Changed it back; garbage. Uninstall/reinstall; great! Change anything.... seriously... anything at all; garbage. It doesn't matter what setting. Speed, infill, support, no matter what; garbage. My current build is 5.8.0

 

Also, if you want a more in-depth description of “garbage”, there are a few issues but the two biggest by far are: A cracking sound coming from where the filament enters a Micro Swiss Bowden Dual Gear Extruder. I'm confident that's not the problem because it worked fine on the last filament and it works fine on this filament as long as I don't modify any Cura settings. The next biggest problem is that it severely under-extrudes, even if I change the settings to extrude more.

 

Any advice would be appreciated.

To properly reset things in Cura (completely back to stock, like you have to set up your printer again and everything) you need to delete its configuration folder. In Windows it's %APPDATA%\cura

 

It would really help us to diagnose the problem if you could post these:

• A Cura project file (.3mf, set it up then go to File > Save Project) of something without changes so that it would print fine
• The gcode file generated by that
• A Cura project file after you've made a change that breaks it (if infill does it that's a good one to change since it shouldn't affect the extrusion of the outside)
• The gcode file generated by that

Sorry for the late response. I have since found this to be a hardware problem. Thanks for the assistance though!!

 

Should anyone ever have a similar problem, the print head wasn't returning exactly to home after a print. I am also assuming there was probably a whole routine of things it wasn't doing because once I fixed that, all the other problems went away as well. It was able to mask itself as a slicer problem because of how I was troubleshooting the problem. Every time the print failed, I was -without even thinking about it- resetting the printer while messing with Cura. A classic case of “don't change two variables at once when troubleshooting”.
