Each cut, took about 2 mins or so. I had to keep letting laser cool off.
Wasnt very fast, but decent pace. Just keep slowly rolling pencil. Till no more smoke, when it hit the lead it just stops.. well didnt keep it on the lead part to long.. Idk what would really happen.. My guess nothing...
Ah found out leads melting temp is 621 F.. I got reading from my blackray putting over 670 F.. Gunna try and melt some lead now lol...
I thought everyone knew by now that pencil lead has no lead in it. It is graphite which is an allotrope of carbon. Trying to melt carbon is like trying to melt wood.
