Your a lucky man… My son only wants to play video games.
He helped me put this whole thing together. He just started his first year of college at Mississippi State for mechanical engineering. We will be able to have a lot of fun with this thing

Thats it. You may want a discharge valve on the pump so you can throttle it down some.
I have mine just barely flowing and it works awesome. You’ll see what I mean…
I’m happy for you and your son. I have a mechanical engineering degree from Rutgers and a thermal dynamics degree from Alabama.
It has served me well for 30 years. I retired because I got sick of waking up in China and India. Now I just take care of a large marina on the Tennessee River. I come and go as I please. Just can’t sit still.

That is awesome John glad for you.
do you know if the flood coolant box is just a relay of sorts? Is the signal just on/ off DC?
I believe so. I don’t know if its a DC control loop? The power supply is DC output so its probably so.
The relay can be DC 3-5volts or can be 12-120v AC.

I can see your first project . Run a carbide end mill through the video game
Lucky I got one on dec 2 I guess.
Hmm I wonder if I can use a standard relay rated for 120v with a 5v coil or If I need flyback protection or some kind of isolation built in. I have a feeling the “Optical” in opto relay has something to do that. This will probably be a better idea. https://www.amazon.com/HiLetgo-Channel-optocoupler-Support-Trigger/dp/B00LW15A4W/ref=asc_df_B00LW15A4W/?tag=hyprod-20&linkCode=df0&hvadid=198090929431&hvpos=&hvnetw=g&hvrand=3422717678390718687&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9031093&hvtargid=pla-348614466893&psc=1
Little more progress on the MR-1! Should be getting close to surfacing the plate soon…
Got the extra windows installed on the doors. Wow, this will be much better to keeps the chips and water out of the windows. I cant remember who came up with the idea for the added window panes, but kudos to you. We got the wash down hose, motor, and line installed as well as the lights installed. Thanks to #Bigdaddy2166 he helped me troubleshoot one of the lights that was not working and we got it going. Got all the drain covers finished 3d printed and all installed… Its coming along pretty well so far.

Very nice 
No issues here, just means more stock to take off. It’s not uncommon to need to remove up 0.060" in some areas.

This works just fine, and in conjunction with something like this: ASI IMACP02 Duplex Three Prong Modular Outlet, AC Receptacle, Din Rail Outlet: AmazonSmile: Tools & Home Improvement you would have your own controllable outlets

Do you have part numbers or a thread link to the added coolant pump and plumbing as well as the led lights?
Here you go.
