A little more off topic of what I have been up to. Tried making my first nozzle based on an expensive printer I have seen on the net. Company I work for received the printer this past week so getting ideas.
Biggest concern was drilling the .4mm hole which is 1/64". I happened to have that size drill. Was able to drill 1/4" deep and thought a little deeper would be nice when snap! Drill broke! I drilled the backside and hoped the larger drill would push out the tiny fragment and it did!
Made a heat block and much to large at first, got way to hot and cause issues. Heat travels up the nozzle and melts plastic to high up causing jams. More to try and learn.
Thanks again for reading!
