Thanks so much (you've often helped me and many other M2 users a great deal). Your pic is appropriate. I just saw this after trying to print a black and red hedgehog by cutting the 1st spool and hand feeding the new filament. I wasn't nearly patient enough nor did I prepare well enough. I failed and googled how to do it and this came up.
Melt Banana has an album called "13 Hedgehogs". Really. I decided to try and print all their album titles and the solution for my problem comes from a Hedgehog. This math teacher is trying to calculate the odds.
Thanks for helping me out.
Joe
