Plugin Help

Any chance someone could help me with development of a plugin that simply does the same thing a $32=1. Would like to be able to change in and out of laser mode without having to update flash.

A plugin adding a M-code for switching spindle is easy to write, how to communicate which one to select to spindle driver code is what is a bit challenging. One way to do it is to have all spindle drivers implement a M-code but that is not very flexible and will lead to code duplication.

My idea is to add an event for spindle change to the core handlers that spindle drivers will have to subscribe to:

typedef bool (*on_spindle_select_ptr)(uint_fast8_t spindle_id);

A plugin implementing a M-code can then request a spindle change like this:

if(!(grbl.on_spindle_select && grbl.on_spindle_select(spindle_id))
     raise error?

where spindle_id is extracted from a M-code parameter.

spindle_id 0 is for selecting PWM output and will be the default when laser mode is enabled, 1 will be the default if not.

I need a bit of time to add this to the core and modify/test the Huanyang plugin...

Saw you pushed this going to be a few days before i can wire in the laser I will update you as soon as I've got it all connected

I did do some benchtop testing and it appears to be working

Finally got to spend some time and test this... Its working very well thankyou. My only request is there a way to have it do what ever $32=1 would do (IE set it to laser mode) without having to the $32=1 (Right now the beam is staying on with G0 moves)

This will require a core change, and the best option would be to set $31=1 and switch to normal mode when the VFD is enabled.

In the next commit I will add a new variable, sys.mode, to control the mode without changing the $32 setting. This can be modified on the fly in a new plugin, or perhaps in VFD plugins, as required.
