My config:
Example gcode:
And the error from the log:
21:15:54 Heating fault on heater 1, T = 235.4 C; still not at temperature after 120.376953 seconds.
I guess thats the root of the problem, that the heater needs too long?!

djar, have a look at M301 in conjunction with the 'S' parameter: [forums.reprap.org]

That's it, you are falling foul of a new safety feature that turns off the nozzle heater if it doesn't reach temperature within 2 minutes. This was added by RRP in their dev branch to offer some protection if e.g. the thermistor falls out. From the temperature graph you published in an earlier post, I can see that you have significant undershoot. So try putting M301 H1 S1 in config.g..

Thanks, thats the solution! 
But still the heater only reaches 238° with setting of 240° (there should be a sloght overshoot during heating up?) - as i understood you can regulate the Voltage for the heater with the M301 command via S? So S1.1 or 1.2 would help?
I have an Enermax PSU with nearly 11.8V - 12.0V under load. Not enough?

Try increasing the value of the W term in the M301 command. If you send M301 H1 with no extra parameters then it will return all the current parameter values.

djar, your hot end temperature in the graph appears to be falling at an impossibly high rate. I think you have a temperature measurement fault, or the thermistor is falling out of the heater block.

Thanks so much, that was the hint I needed - I exchanged the thermistor - one of the legs was nearly loose. So I think it lost contact while moving - at least thats the only thing I could think of...
New thermistor and a straight temp line - everything like it was and should be!
Thanks again for your help and work on the firmware.
