R-CNC Xbelt upgrade Belt outside

an upgrade of the R-cnc with the belt going trough the Y blocks

works with a 232mm belt (with an added bearing)

or with a 180mm belt (without bearing)

ATTENTION. The XLEFT part is mirrored !!

I'll change it later.

The 180mm belt is untested but the math is good.
Ok, the 180mm belt is tested and it works nicely.
It's better to use the 180mm belt if you can.
