Geeetech

Thanks for your help.

I traced the 24v back to the board.
But finding whtas wrong exceeds my skills.

I think there is a short where the PWM is controlled/set

So, i checked the voltage at 0 - 24v
on 100% ( 255 in temperature settings ? ) - 24v
But also 24v at any other speed

First i have to get a multimeter
I'll check it then and telling you the result

Compiled yours with 1.8.8
Stock firmware was a hex file (A10_G04_V1.1.8_3Dtouch_01.hex) from the Geeetech homepage

Something wrong with the breakout board or with the mainboard ?

No, its plugged to the PWN connection

I cleared the eeprom after every flash.

I tried to set fan to 0 ( menu ->temperature ?) and stored the settings, same effect
Also tried to clean the eeprom again, fan is always running

I'm using your 2.0 latest beta.
I already tried the 1.1.8 stock firmware from the Geeetech homepage - same behavior, the part fan is always running

Hi,
after my last print the part the part fan didn‘t turned off.
Even after resetting or rebooting the part fan is always turned on, is runing at 100%.

GCODE M107 is also not working

How can i fix this ?
