After expanding the axles of the Topscnc it became imprecise due to the low rigidity, so I am going to start printing the Heavy version measures 800x800.

I just need to decide if nema 17 or 23. In the current use 17 of 2.5 A and I had no problem, but since heavy weights more and that at some point I will cut aluminum I would like to hear your advice. What engines are you using? Is it worth investing € 120 in the nema23?

Thanks topsie for sharing your work. I will try to contribute so that you continue.
