Honestly, PLA is sufficient : if your bed levelling is good,it slips well.
I noticed that printing it on a glass bed is better (the surface is smoother).
You also can add a little acetone with a brush to smooth it out.

It looks like its switching voltages ? If so it won't work, you will kill the MMU at least. The 3 pads on the MMU board use a spdt switch which switches mad9 in and out of circuit. Hum ok, but look at the 3 green cells. it seems it just add continuity and no voltage. So maybe it could get 5V somewh...
