Having trouble installing the PT100 upgrade on my Kossel Mini (v2 from think3dprint3d.com).

Bought the original E3D3 PT100 sensor with the amplifier board.

I have a ramps1.4 / arduino Mega 2560

Followed instructions from http://wiki.e3d-online.com/wiki/E3D\_PT100\_Amplifier\_Documentation

After update I read 1100 degrees from sensor with extruder heater off and I have a MAXTEMP error?

Anyone successfully installed a PT100 sensor on a Kossel Mini? Or had the same error?

When I connect in Pronterface I receive this at end of connecting phase:

echo:Home offset (mm):
echo: M206 X0.00 Y0.00 Z0.00
echo:PID settings:
echo: M301 P22.20 I1.08 D114.00
Error:0
[ERROR] Error:0

: Extruder switched off. MAXTEMP triggered !
Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
[ERROR] Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
