3 point bed leveling?
Using bl touch I would like to probe 3 points to alow for linear bedlevling before start of the print
I am confused about how to proceed with a routine for this and looking for pointers
I do NOT want to use mesh bed compensation
It's possible to do that using the old 3-, 4- and 5-point bed compensation support (G30 commands in bed.g), however that feature is deprecated and likely to be removed in a future firmware version. The recommended alternative is to use a mesh of just 4 points, one near each corner of the bed. On prusa-style printers with beds moving in the Y axis, this has the advantage that it will compensate for Y axis twist too.
