When I connect to Pronterface there is the error message.

Error:Temperature heated bed switched off. MINTEMP triggered !

[ERROR] Error:Temperature heated bed switched off. MINTEMP triggered !

Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

Hi Isabelle,

does the printer work without Pronterface? Do you have the latest driver bundle from http://www.prusa3d.com/drivers ?

Let me know ;)
