Under Extrusion Issues
If you are getting under extrusion please try the below fix. Usually this will happen if you change the filament diameter thinking it needs to be changed. The filament diameter function is for volumetric extrusion control which is NOT used on these machines.
To fix the issue send a M200 D0 followed by M500. This will disable the MM3/Volumetric control and get you printing again.
DO NOT MESS WITH FILAMENT DIAMETER SETTINGS EVER. Doing so will enable MM3 and cause issues.
We have removed this in all releases from 1.1.7 and up to prevent users from enabling this. The MM3/Volumetric extrusion is not used by 99.9999% of people.
