Any recommendentations?
And I probally also need a new fan, also any recommendations?

Edit: It seems like I destroyed it

You burn thermistor (read temp) or cartrige heater?

Thermistor is 100k, cartrige heater 12V. I like Trianglelabs, they are good price and decent quality.

For the fan on 40x40x10mm 12V, assuming you have starndard MK8 extrusor.

Best regards.

Probaly, but when it turn the power on, nothing happens, and the lcd screen gets turned on, when I connect it with an laptop, but then I cant controll anything.

So sth. must be broken

Sound board dead... Probably the short broke the board (GT2560 Rev A+)

Best regards.
