Maslow4 - possible to add spindle control in the future?

One thing I miss at the moment with the Maslow4 is spindle control to be able to turn the router on and off automatically. On my old Maslow, I could take off the controller pins and have an aux outlet that toggles based on the GPIO signal. With the Maslow4 design I don’t think there is any way to do anything similar.

I was glancing at the FluidNC docs and noticed that there is a Notification mechanism that can send events. Could it be possible in the future to leverage that mechanism to build a network based solution to be able to toggle a smart plug on and off to control the router? (Maybe an IFTTT trigger)

By the way, I thought I’d also mention that with my current setup I also turn on the dust collector whenever the router turns on (the aux outlet generates a trigger that I use to turn its smart plug on and off based on whether the outlet is energized). An IFTTT trigger would allow multiple actions off of it.

Both of those are 100% possible. Maslow4 also has an aux plug which can be used in the same way and also a network solution could be nice because no wires needed.

I’m interested…I just ordered a 600W brushless DC spindle, and hope to build a closed-loop speed controller that can optionally receive GRBL/g-code spindle commands including start/stop and speed settings (I’ll probably use a Raspberry Pi Pico, since I’m learning that ecosystem for other projects). I’m wondering how to best enable communication between the Maslow 4 and the speed controller.

I would start here Spindles | Wiki.js
the only thing that is Maslow specific is what pins are available to use (and
with the JST versions, there should be more pins as there are fewer LEDs on the
encoders and jacks)
