Hopefully an easy question.. I would like to run an iot switch (like this: Controllable Four Outlet Power Relay Module version 2). Is there something special i need to do at the beginning/end of each tool in the program to trigger it? or does fusion already trigger the output on the black box?
M3 turns the tools on. M5 turns them off. If you have something plugged into normally on, these commands invert. Simultaneously. That's all you can do with this setup. I pretty sure BlackBox has pins to control other accessories and an onboard relay( max 250 / 125 AC 10A,) If you use this relay, aim to be *under* the max rated and be careful switching inductive loads: use a cap and a resistor (or mov) across the load if you are switching motors, coils, and other relays. Here's some examples of protective measures for switching loads with relays. Good luck!
Grbl has coolant outputs too, one stock and one configurable when compiling from source through the Arduino IDE. Also a spindle direction pin, which most people don't use. The question is how that translates through the BlackBox hardware, which functions as an Arduino Uno (ie. should contain an ATMega 328P microcontroller IC, 5V, 16MHz) but I assume uses some non-standard Arduino hardware implementations as part of @Peter Van Der Walt's "hardening and simplifying" process.
Its as close to original spec as possible! Coolant output does have a Mosfet in front of it though (simplified so users can just hook up a 24v solenoid or valve or DC pump without extra wiring) Of course the IoT relay takes 24vdc too, so wire up a second one, and then use that output to control the second IoT relay if you want to switch AC coolant. Other than that, M3/M5 (Don't forget the S-word - ie M3S1000) works as always where S = set by $30 and $31)
I guess this shows that i can hook it up, but does fusion program in the m3/m5 already or will i need to manually do it? OpenBuilds BlackBox 4X Documentation
M7 M8 M9 are your coolant commands (only one of either M7 or M8 works in vanilla grbl, I forget which), which you can select in your operation setup in Fusion. It'll automatically put in the M9 somewhere, I'm not sure if before the spindle turns off, after, only upon a toolchange command, no idea. You'd have to look into that. How you manipulate it and move them around to do what you're trying to do in post-processing is another matter. M3/M5 are your spindle commands, nothing to do with the other pins.
Just check your gcode, that it has M3S1000 (as M3 on its own doesnt set the PWM explicitly and last PWM value could have been something other than Max RPM. PWM can be used for spindle speed control if you have a SuperPID or VFD, otherwise set it to maximum so its on/off control to play nice with Relays)
I'm using open builds control of that matters Basically I want it to turn my router on at the start and turn it off at the end.
You're using the IOT switch purely for your spindle and nothing else? You hadn't actually stated above what you were using it for, which is why I wasn't jumping into the spindle thing. In which case, as Peter says, just use M3S1000 to turn on, M5 to turn off, and plug the IOT input into your spindle output.
Sorry yes i want to simply using it to turn on the router (makita) and turn it off With the open builds post is there a way to do this in fusion or do i have to do it in an editor?
@David the swarfer 's the author of that Post, and I'm not actually sure if it does add it so lets wait for him to reply
Yes, it always outputs M3/M5 commands for spindle control. If you tick 'flood' for the tool coolant, and turn on 'has coolant' it will also output M8/M9 for coolant on/off. Here is the tool selection Here is the post setting And here is the resulting Gcode , spindle on in blue and coolant on in red (oh dear, the editor lets me set colours in the code block, but it is not displayed in colour so I have inserted comments after ';' characters so just search for those Code: (Made in : Autodesk CAM Post Processor) (G Code optimized for OpenBuilds OX,Workbee,Sphinx,Lead with BlackBox GRBL V1.1 controller) (Program Name : 1001) (2 Operations in 1 files.)

If i got you correct all i need to do is hook the iot up according to the black box documentation and im good to go?
Default grbl $30/$31 settings are 0-1000 "rpm". 10,000 will; still turn the relay fully on, but just a note that needs a check
