Last week i stumbled on this forum and started reading about hacks for Cube 2, which i own. So now i'm printing stuff sliced with Kisslicer, bough my first non-Cube filament (not tried yet) and opened my Cube up to fit two cartridge chips behind a switch (jumpers), so i really don't need Cube cartridges anymore. Thanks for the these, my printer just seems so much better now  :).

I stripped all plastic covers off my Cube and i might leave it naked, as it seems that those covers were amplifying to noise. I don't mind about the aesthetics, only the functionality :)

I noticed a mention about lowering the power fed to the steppers using ports on mainboard, to make the printer more quiet. However, i don't have any potentiometers on the mb of my Cube. I did some measurements and one line to stepper was reading about 2.0V, so apparently there's room to lower (if that was the proper voltage anyways...), but just need to figure out how. There are 4 a3979slpt stepper drivers which i believe to be responsible of the current fed to the steppers. Looking at the datasheet, there are two Sense pins which probably control this, so changing those resistors might do the trick. Need to do some measurements. Also, if someone has pots on their Cube motherboard and can send me a picture of the, that might be help.

Also there was a mention about using a Zener diode to block the writes to the cartridge chip. If i'll find a Zener diode, i'll see what it does now that the machine is taken apart.
