The way that I would like to do it is to remove the restriction to G0 moves. And I would also quite like to remove the restriction to only working on rotary axes. The lock/unlock pins would be a really good way to handle the old-style CNCs with one motor that is clutched on to each axis on-demand.
As a workaround I came up with a HAL component that sets feed-override to 0.0001% (it needs to be tiny but non-zero, so that it can see if an axis is moving). If it sees no rotary move then it locks the axis, otherwise it unlocks, waits for an "is-unlocked" and then allows normal motion.
I thought that I had written such a HAL component, but I can't find it now.
A possibly more reliable approach would be to run the G-code through a filter file (this can be configured to happen automatically) that inserts command unlock - wait for is-unlocked ..... command lock - wait for is-locked G-code as required in the input file.
