Is there already built in support for the BL Touch ?
Can you give more info about this?
I was looking at auto bed levelling and I made a wrong assumption that astro effectively replaced the firmware on the printer. Meaning all the firmware did was action the commands given by Astro.
It seems that you can add a bed levering tool that aids printing and saves you having to level perfectly. I know that octo has some integration that allows you to actually see how warped a bed is and compensate.
