Hello, I am trying to change BED_MESH_CALIBRATE routine to be able to compensate the second head also for duplication and mirroring ( I have already implemented IDEX into printer.cfg - dirty version already exists somewhere). The math behind this is quite straithforward, but I am lost in implementation. Can you somebodey give me a hunch? I am afraid that this is not easily implementable into printer.cfg - as I said - please give me somebodey a hunch where to start. Mirroring and duplication with bed curvate around 0,3 is impossible but it is quite easily (mathematically so far) solvable using 3 independent Z axes.
