Hello Geeetech.
I am using two Colorfabb PLA filaments on the 2-to-1 extruder, the hotend keeps doing one of the two:
a) Jams completely.
b) jams partially - and then only one color can be extruded.

whenever I raise the temprature try to unclog using this method, I end up melting the PLA inside ...

Hi, first of all costumer service is sending me a new component - which is a good sign.
the second thing is that the component was already mounted to my board when i got the kit, the only thing i did was placing the heat sink
thanks for your attention

Hi , Two things
a) i tried to switch places with the A4988 module ,and my z axis works.... - which means the module isn't working properly
b) please read Geeetech datasheet about the maximum voltage for this component : http://www.geeetech.com/Documents/A4988-Datasheet.pdf
c) please send me another ...

obviously, this is where i measure....

I have tried that, the screw is very jumpy, i can't fix it on 1V
it jumps from 0.3V to around 4.5V in the slightest turn of the screw.

Hi there, i have the same problem
could you please explain to me what do you mean by that fix?
where do i measure the Voltage?
thanks
