allows you to interact with all your printers via the Cloud, and many other exciting new features.
Use a 2mm brim, go through the documentation and the old videos - those ends got fixed months ago and they aren't sharp anymore. I printed 4 stocks on a 1kg roll last week with roll to spare (on an old prusa mk1), just to say that support usage has been and still is being reduced and the only troublesome part at this point might be the buttstock (which is being simplified). Overall it is the price of having the current joint design, which will not change due to the praise it has received and its success.
I'll be happy to help you to the best of my abilities (shoot me a DM) if you direct me to a specific technical problem you might be having, or a question with a part that you don't know how to print. Looking forward to ending your nightmares.
