Using an Ender 3 printer. Following the recommended settings on the Filaments roles, on all prints, the good and the bad. Each roll of filament is fresh out of the manufacture package. From two different manufactures.
Both prints on the left, the top = wall anchor,,, and the bottom == spinner top, were printed with PLA from the time the printer was new. 2 rolls of PLA where everything printed great. Both Pints on the right , the = wall anchor using the same Gcode used to print on the left ,,, and the bottom == Using the same Gcode used to print the spinner top on the left, the difference is that on the right a PLA-F filament was used, and when that failed print as above on all prints, tried a new roll of Pla which printed this same way – massive misprint.
Looking at it as a possible Under Extrusion due to a part plugged nozzle, I replaced the nozzle with a new one. It printed the same way -- failure.
The diameter of all the filaments measure the same with a micrometer. Now I can guess at what to change next and use up half a roll of filament testing each change, only to find that the next roll of filament I buy will force all those tests again.
Now I believe that someone out there has already had this same problem and found the solution, so I hope someone out there can give me an answer.
