Tiny-M VS micron

Check out Tiny M. https://github.com/gsl12/Tiny-M

You may want to try your luck by remixing the parts you want from a Tiny-M (https://github.com/gsl12/Tiny-M), a mod of the V0 that uses 2020 extrusions and NEMA 17 stepper motors.

yes. but probably not to 250mm. also you'll need larger extrusions. 1515 isn't stiff enough for that. https://github.com/gsl12/Tiny-M

If you want to build a V0 with NEMA17 stepper motors, you should take a look at the Tiny-M: https://github.com/gsl12/Tiny-M It's a printer based on the V0, but using 2020 extrusions instead of 1515, and NEMA17 motors instead of NEMA14.

Yes, he just started to publish the mod (https://github.com/gsl12/Tiny-M/tree/master/usermods/triple_z_belted/STL). I am still thinking about it for the 150 mod

By myself from source https://github.com/gsl12/Tiny-M

But here's the github repo for a 150^3mm and there is a usermod for the 190. https://github.com/gsl12/Tiny-M

There is the Tiny M, basically a 150mm3 V0 using 2020 extrusions instead of 1515. The cantilever bed might start to be an issue going much larger than that.

The Tiny M is what you're looking for
