Hi Anders I am probably not typical of the "almight board" but I tend to encourage experimentation in most any direction seen to be of value by users/developers. The board tends to fall out on the evolutionary side when it comes to development in this project. As we progress we still need to keep our eyes on the CNC "industry" so that our CNC development is consistent with best practice there. We also need to keep our eyes on the existing architecture that is used by the current system.
This notion of somehow moving feed override down into the HAL raises quite a few concerns for me. As I remember the early HAL discussions it was not intended to do any thing but make hardware connections. Several have imagined a HAL that needs none of the old EMC code in order to make a machine work. NML has the messages needed to scale things like axis and spindle speeds. HAL and halui provide a interface to these systems right now. As halui was being developed, I imagined hardware being connected to these various pins including feedrate and spindle speed. The halvcp code does add to that by offering the ability to develop displays that show and interact with HAL but IMO we must keep in mind the difference between HAL as a hardware connector/operator and EMC's motion control functions and build interfaces appropriate to each.
