Bed leveling Balco 5.1 and Tronxy sensor (no BLTOUCH)

Hello,
I use a Balco 3D printer (Aldi) the motherboard is a 5.1 Wanhao … I flash the firmware 4.0.6 but I don’t use BLTOUCH instead I have a Tronxy xy-08 that works perfectly.

I would like to know if it would be possible to add in the next firmware the possibility of changing the polarity of the Z-probe. I explain, I add a CD4049 to reverse the signal of the Z-probe with my Tronxy.

At the same time updating the bed level with my Anet A8 the measurement is done in 2 steps. a fast descent and a second at a slower speed which makes the measurement capture more accurate. Is it possible to adapt the firmware for its type of level sensor?

If not, I am satisfied with the result of the simple and effective modification, congratulations on your work.

Sorry for english it’s google translation

Looks like very specific to your setup so probably no.

Yes. Look at MULTIPLE_PROBING.
