Runing 2 Z axis and 2 spindle independent in the same time

[dc42]

@martin7404 I think you would need to take a similar approach to the one we are implementing for multiple GCode streams in RRF 3.5. The approach is to run two sets of GCode instructions simultaneously on two tools with independent axis systems, but to synchronise the two instruction sets at particular points, by having the one which finishes the instructions up to the sync point first wait for the other one to catch up.
