Hi Everyone
I Recently aquired a Ultimaker 2, as a upgrade to my old Vertex 3d printer. I then noticed i got some problems with the print to do with retraction, where the knurl would grind the filament instead of feeding it.
After a quick read thorugh of the problem i decided to by the feeder upgrade to make the printer a 2+, https://www.makers-hut.com/product/ultimaker-2-extruder-upgrade-ultimaker-extended-go-2-3d-printer-geared-extruder/ .
After i mounted this with great difficulties since part was missing. I started to print however the feedrate seems to be stuck at what is was before hand where it fed properly. I did download the latest version of Cura 2.6.2 and then i updated the firmware of the printer, and this didnt help either.
I am running okay settings for a 0.4mm nozle:
layer height: 0.1mm
Intial Layer height: 0.2mm
Wall thickness: 0.8mm
Top/bot: 0.8mm
Print speeds tried: 30mm/s, 50mm/s and 60mm/s(last one is my usual one)
I have not enable retraction
and Combing Mode is set to all.
Im using PLA , where i heat it to 210 degrees and have the heated bed at 60 degrees.
Im using RS Pro Black PLA 2.85mm and the material is not deviating from the size written. I can push material through the nozzle manually hazzle free. It just seems like it is moving to slow and the print it makes is classic examples of under extrussion, where you get small pellets or missing layers, i just dont have any idea how to fix it.
This is why i come here for help
Thank you in advance
Jacob
