Hi Andy, I hope you're doing well :)
Thanks for the insight. Didn't think about using an STL file to determine
the bounding boxes. I was just thinking about plain HAL logic because it's
not that I need to cover a very complex geometry. But it's a pretty nifty
solution and a good way to improve my
I'd really recommend not using copper sulphate. It is corrosive to many
metals, especially aluminium.
In my laser and tig welder I use 20 - 30% propylene glycol in
deionised/distilled water. Propylene glycol is the active ingredient in
most RV antifreeze, without the dye and other additives.
I have been running normal green automotive antifreeze diluted to about 25%
with distilled water, for our liquid cooled spindles. (But we've only had them
for about 5 years.)

Not too bad a price once Amazon breaks up the 6 pack minimum. OTOH, it
does read like nasty, dangerous stuff. I'll see how well todays cleanup
works, first.

The color is a dye to identify what kind of additives are added. In general,
green is the older concoction and is designed for steel and copper, whereas the
yellow or orange stuff has additives that are better suited for the plastic and
aluminum coolant system parts in modern vehicles. I don’t
Once biologics get into a system, clean out is the first step. However, no
amount of filtration can remove them all, if you don't kill all the
bacteria it will come back.
Just passing along what I learned from a Rustlick rep many years ago.

I bet the coolant made for Toyota Prius engines and power inverters would be
ideal for a CNC spindle motor. It only comes as a premix, and is only available
from Zerex or Toyota. It's made with distilled and deionized water so it's
completely non-conductive.
What might be a strike against it is
