How do you cold pull fast!!!
do you do any thing different then the instruction on prusa when cold pulling, is there a fast way to do it?
is this a good method
These guys pull as the nozzle cools to 100C. I like the method to let the nozzle cool completely, then set the temp back to printing range and start pulling up firmly as the nozzle temps crosses 70C. It should pop out at about 90-100C. I also like eSun cleaning filament since it will extrude at a wide range of temperatures. If a bit gets stuck, it won't cause problems on my next PLA print.
The video overall shows a good technique for keeping the nozzle clear.
