For next semester - you must ensure that the code works, run it and do validation - e.g. make several kg of filament from different starting materials - to record and share optimal parameters- then put together in an update article on the recyclebot -- integrate in the new diameter sensor https://arxiv.org/ftp/arxiv/papers/2012/2012.00191.pdf and when you do the BOM/costs make sure only to include what is actually in the recyclebot. -- Joshua Pearce (talk) 13:53, 21 December 2020 (UTC)
