Voltage for hotend fans and extension board for A10M

[HelloMrBirdie]

Hello,

Back again, I have noticed something weird about the Geeetech extension board for the GT2560 V3 that comes with the A10M printer. Now I say weird because I have limited experience with electronics so it may be normal . Ok, so I put my multimeter on the blower pins and I get 24v, which is ok, yet when I put the multimeter on hotend fans 7/10 I get between 40- 140 milli volts, and I am not sure what I have done wrong, is something broken, or is it something in Marlin firmware that may be limiting it? Some help would be awesome!

Hello, maybe the printing temperature is too low? Try to increase the temperature of the nozzle. Or you can loosen the screw of the extruder, maybe it is too tight and the filament extrudes slowly.

Hello, is the fan working normally? If it works normally, there is no problem.
