This printer shined past the other printers I just mentioned completely stock and they were upgraded. The additional features of linear advance are not worth the price I’m paying for awful print performance. If there is a copy of the stock firmware available, I would greatly like a link to it so I can put this printer back to stock. This is the reason I would really like to have the stock firmware back….CONSISTENCY. This issue was not present in the stock firmware. (open gaps and filament not sticking in some places) After running the bed leveling print a second time, the layers are gouged (changing nothing), the paper drags heavily and would be too tight. The first print I set with paper and it drags lightly, just as I had set it prior to the upgrade, but the squares look like the bed is too low. I can level the bed at 60C, do a bed leveling square print with PLA, let it cool and do it again with totally different results. Now, I can’t even get bed leveling squares to print accurately and without defect between prints.Īfter hours of testing, adjusting and searching for solutions on the Internet, I believe there is a problem with this firmware. Prior to this update, my first layer was nearly flawless and was the smoothest I had seen from several friends’ Enders, Makerbots and Dremel printers. However, after the update my first layer print quality is TRASH! I went back through all of the previous calibrations of extruder, filament flow and now PID tuning just to be sure that wasn’t an issue. I installed the updated Marlin Firmware 2.0.5.3 as defined in this article.
