I know that amazon search was there also in 16.04 because it was my first distro and in my country i only briefly heard about amazon so it looked cool to me to have one button to order something but i never clicked on it because i tought it only works in rich countries or something. At that time i didnt gave a crap about privacy i was sold on it because i liked the design of unity and the fact that it looks different than school pcs with windows so it didnt remind me school
Thanks for the tip the extruder wheels were dirty from all the grinding but there is a tensioning spring and i have it quite loose because i had an issue with PETG because i have my printer in enclosure and with bed at 80C in enclosure was so warm that my filament which is inside the enclosure as well was so soft that extruder squash it a little bit and it git stuck inside that longer ptfe tube which is between extruder and hotend
