Hi there,

I’ve just bought myself a Balco 3D printer for Christmas from Aldi. (rebranded wanhao i3 plus)
I had a look inside to see if it was possible to upgrade to a self leveling using the BLTouch.

I couldn’t see any labels for a z-probe and also main board version is v5.2c. (Not the normal 5.1 or 5.4 for the mk2)

Does anyone have any info on attaching a probe to this board? As I can’t seem to find any reference to it on he web.



unfortunately this isn’t possible.
Normally you need to upgrade to another mainboard.
You can try to fake it on the Z endstop but that way it isn’t possible to actually use auto bed leveling.


Ok thanks,

Is it possible to switch the board out to either the 5.1 or 5.4 boards? And is it just a straight swap?

Thanks again

I don’t know anything about those boards. I swapped my Wanhao duplicator I3 main board for a Arduino DUE with RADDS 1.6 (for 3 extruders). that’s always possible.
You also could swap it out for a ramps setup, but if this is your first printer and only printer i wouldn’t advise it.

If you do proceed I strongly advise you to actually print everything beforehand because you need extra parts, also print spare parts for it.
