ABS DELAMINATION - STUDY FREE " UPGRADE " CR10 EXTRUDER UPDATE 11 NOV 2018 I fix the extruder problem on my printer. https://www.thingiverse.com/thing:3204964 Lessons learned: 1. Bigger isn't always better! 2. If it doesn't fit, don't force it! 3. The behavior of a spring is the same as any other solid. Creep, otherwise called cold flow, is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses. It can occur due to long-term exposure to high levels of stress, which is still below the yield strength of the material. Therefore, an extruder spring may lose its original properties - in time... or ...a different and more probable explanation... a poor design - the spring was always bad! Only your expectations change over time! See, it's not the spoon that bends; it's only yourself. 8 NOV 2018 When all your prints are bad and under-extruded, maybe it's your extruder. Again, poopyyy prints... I dismantle my extruder... force with a plier the spring... extend it a little, so more force will be applied to the press gear... and... what do you know! My printer starts printing again! Mather-Father! That poopyyy little part... gave me such a bad time! For all CR10 owners, with original Extruder on printer, if you experience under-extrusion / delaminations, a possible solution may be to extend your Extruder Spring. Disclaimer!!! Do it at your own risk! Damage may occur to your printer! I will design a SPACER/WASHER to be mounted between spring and ROLLER ARM! As soon as my print plate is clean! :) A lot to print! https://www.thingiverse.com/thing:3204964 6 NOV I found the proper setting for this filament... My CR10 prints like it's no tomorrow! Only I'm to blame for the previous failure. Always make a print test, no matter how "in hurry" you are! 3rd NOV After four days of printing, I realized that printed parts are useless... not so good! Before starting to print the 40mm Vacuum Cyclone, I tested the printer settings on ABS filament. Great print! Since it was a long print, both prints took almost 1 kg of filament... I trusted the previous test and didn't test the new spool. Big name, big price... big failure. Before I realized the print condition, I already started another print. Print what I stopped after 30 minutes, when I realized it was something wrong with my prints, and inspect the part... same delamination! Lesson learned: Unless printing with similar batches of filament, take the time to print a test, no matter how small. Adjust your settings and decide if the filament is fit for your project! The main reason for delamination and under-extrusion I consider to be excessive print speed - this when the rest of the basic failure reasons are eliminated - like temperature, clog head, clog feeder... etc. Better to take the time and print-test the limits of your filament than to lose time, money, and good spirit. Two printers aren't built the same, this goes for filaments too! *** Friends, Two and a half men, Matrix
