Thanks In in South Africa, we have RS locally so will try them. I see there are a few variants does this one look suitable?

ATSAM4E8EA-AU

Dave can you point me in the direction of a source for the SAM chip?

Thanks Dave I will give it a whirl after I have my new one fitted

Oh gosh you are right sorry late night !! I have dome some SMD repairs before so I will take a look when I remove it. Dot think I have done so many legs before though (older Atmel stuff mostly)

Hi Dave,

Just checked my original order and it was in September… so I guess it is still under warranty! I am in South Africa, so what do I need to do to claim? I have ordered another in the meantime.... but it would be good to have a spare...

This doesn't work either…

M307 H4 A90 C700 D10 I0 V0 S1.0 ; remapped to heat bed From Duex5 E4 temp sensor
M305 P0 X4 T100000 B4388 R4700 H30 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction

Still cant understand why when I have no thermistor plugged into the H0 Heatbed pins … it reports 25.4C on the display??? Where could it possibly be getting this from.... I would expect a heater fault error and a 20000 display....
