I printed with my Rapide 200 a lot of models for months.

Today something happens: printer and PC do not comminicate more (Windows).
SD card works perfecty as before.

I changed PC, changed USB, re-installed drivers, do many things but nothing was useful.

PC stil recognize rapide lite 200 correctly as USB rumba.
Repetier Host connects printer but stay stuck "Waiting 7 process" without recognize Temperatures.

Any idea?
