custom firmware didn't work anymore

[roald 2]

the problem: without any reason my hot-end don't want heat up anymore, and the print start window show only the hot end temperature and not the temperature of the heat bed, when i press start print the printer don't heat up anything.

what i have:* ultimaker original,board version 1.5.7

*selfbuild heatbed relay driven epcos 100k thermistor (4.7k pullup),

*reprap fullgrapic smart controller

custom firmware i use from: *https://bultimaker.bulles.eu/

*cura 15.02.1

already tried: *default firmware (measure a bed temperature of 1100)

*custom firmware from http://marlinbuilder.robotfuzz.com/index.php without reprap controller

(same problem don't show no bed temperature)

*other usb port

*change from pc to mac

*disconnect power for one night

 

i had this same problem one time before and it solve the last time because i don't use the printer for weeks

but now its back again. i also have sometimes an other problem with detecting baudrate but is solve that problem with switching from usb port

@Nallath, do you have any tips for Roald?

I guess its a hardware issue. If suddenly the printer doesnt work anymore it's usually not a software issue.

You could try putting the heater cardrige (and temp sensor) in the slot for the second extruder and check if that works. If it does work, your electronics is broken. If not, its probably the heater cardrige.
