Extruder Extension Board from Geeetech

[GameServas]

Hi, is there anything to change from the wires when i connect a new extruder Extension Board to my A30? on the original board all temperatures are ok but on the new from geeetech the hotend shows minus degrees and fans don't turn

Hi, You can check if your hot end thermistor is fully connected.
Check your fan connection location.

I checked yesterday all connection 2times but i have only 15volts output on the connector for proximity switch(i think the new board is 12v), on the old(original board) the output is 24volts on the same pins. my A30 is a 24volts version but i have not seen anything on the website with 12v version and 24v version.
in the first step i thought the board is defect but i ordered 2 and on both is the same. so i went back now to the original and think the boards are for the trash can.
