Open Bed Leveling System (Open BLS)

I found myself with a bunch of time on my hands because of what is going on, after months of on and off internet research and YouTube Videos...... it is complete!

I present to you Open BLS (bed leveling system) an open source bed leveling solution to fill a void (I think) in the 3D printing community.

Using a octocoupler is nothing new, and boards can be imported very cheaply, however, they are often very large (by comparison) and use cheap components.

Tailored solutions do exist, however the ability to purchase components individually instead of a complete package is currently not possible.

The intent is not to take away from others in the 3D printing community, rather, provide another option.

I have been using this system daily on two Ender 3 Pro and a CR-10 on RepRap Firmware 2 and 3 for over a year.

I have tested it with Marlin, it does work, however I am huge fan of RepRap Firmware, and use RRF on all of my machines.
