We have been waiting for you to jump in @Jeremie with a low cost FOC for the BLDC's and gearboxes.

Btw, Tinymovr is also about to release its version of an open source leg for a robotic dog...we had him in our BLDC controller checklist, I am on his Discord and he seems to be actively developing. So it might be something to keep an eye on!

Also I thought, I'll just share this...just in case you guys wanna laser eyes the list!!

@ptp that patent looks really cool, maybe I will try to figure out how this works...but to get the belt length right might be super complicated!  Could be fun though!!

Just had to put this here...its too sweet!!

LOL, I love these old instructional toons. What do you think? From the late 50's early 60's?

New Printer Turned up, I remember last time I assembled a printer I said never again and yet here we are.  Instructions said 8 hour and yet 10 hours later ....   now I need to do the wiring but after half a dozen beers, I think I will walk away until tomorrow. 

Nice one @Nink congrats to your Prusa!!! That one is a beast...never failed me since I build it, and its been three years so far!!
