Mike,
Epic reply brother - thank you ... just the type of thoughtful detail a newb like me needs. Pretty much nailed what Im after and where Im stuck. I have elected for the Solid State Relay approach. My SSR is 3-32v Input side ... 24v-380VAC. I have a remote On/Off rocker switch in my circuit as an added twist to the standard arrangement - but pretty straight forward.
My SSR in middle and Coolant power outlet wired in over to the Left.
The 110v side is pretty well sorted .. where Im hung up is on the C11G [ C11GR rev 9.xx to be exact ] ... Going from the C11GR to the input side of the relay - one would think would now merely be a trivial matter - but so help me the documentation for this is just mind boggling sparse or non existent. Several of the diagrams and solutions Ive seen appear to me to be using the pins for the 4th axis ? Id really NOT like to do that. Do I seriously need to rob pin outputs from the 4th Axis to have Mach3 control coolant power / on / off ? COM is jumpered on my BoB as 5v+
Here's a snippet of a diagram I have been using to model my Control Cabinet after ... with C11GR manual page side by side ...
So ... where i keep getting stuck is .. how would using the pins of the COM/5v+ that is "between" Pin 8 and Pin 9 in combination with PIN 9 ... effect my later use of say 4th axis stepper driver connection to PINs 8, common and 9 to a stepper driver ... and these connections for flood coolant? Seems they cant share these PINs right? [ I know this sounds super dumb-newbish ]
The docs about useage of my currently unused PINs [ 1, 14, 16, 17 ] leaves me scratching my head wondering how and when they can be best utilized ...
With there being a 5v GND pin between PINs 16 & 17 ... is it possible to set this BoB up to use that GND - wired to the Negative [ PIN4 ] of the SSR and PIn 14 on the C11GR as the 5v+ going to the SSR on [ PIN 3 ] + positive?
Or do I just need to give up on the notion of leaving PINs 8, Common [ 5v+ ] and PIN 9 open for future use of 4th Axis - and wire it up for coolant?
To further complicate this discussion and add another twist .. If im understanding some of your reply regarding using one of the C11G's 3 onbaord relays .. I could technically run 110v power IN to one of the relay connections, and run 110V OUT via the NO side of the relay to the 110v wall outlet Ive wired in? Strapping 110v to this BoB freaks me out - if Im interpreting that part of your reply correctly.
That said it has me wondering If I could some how use one of the 3 relays [ or the one I will not use for Spindle Control ] - as a relay to ... switch my other relay :-) ????
I feel like Im super close to finalizing this thing - theres just two or three loose ends where Im confused and this is one ...
Current status of Box ...
Hoping to be detailed here in this posting to help others looking for these answers as Ive spent literally 3 days googling and searching this forum for these answers, which astounds me its not readily avail out there in either sample diagram or thread posting ... after I get this sorted Im going to make a sample Diagram and post in here and my build thread... something thats post 2007 - lol. Perhaps Im just dumb and bought an ancient board and should have gotten something more up to date ? I dunno ... seems like a pretty NICE BoB - just wish it had a more newb'ish friendly manual and forum of support.
Thanks for any and all help ...
