I Ididn’t check bit yet, but I have found big wobble, so that needs to get fixed even if I want to upgrade to LR4, because I will have to cut struts as best as I can.
ok! I had no idea toolpath could do that… how exactly? Or do you mean path which leads to holding screws? 
I tested that recently:
I absolutely agree with this! I have bought one and it’s been in use all the time! I look at bits/electronics and my kids on dirt/dog’s fur/cat’s fur/beetle/ant/leaves/[here goes long list of other items]
Perfect educational toy 
I’ve tried to start core print earlier today, but failed. I wanted to do it quickly, so decided to use 0.8 nozzle for the first time in my life, so, er, well… I mean… everyone can have bad ideas, right? Right?
The problem with that, I suspect, is I own Ender 3, so I suspect it was unable to heat enough filament, quick enough for such nozzle and layer width of nearly 1mm.
I will probably start it now with just 0.4 which I know how to use… unless you have ready made profile to share? Anyone?
