The coolant pump is the same one that is used in computer cooling systems. It is a Syscool PC cooling pump available on Ebay for about $14. If your system is brand new, I noticed that they changed the cooling pump and it has a larger tank on it. I have not seen that pump, but if you go to any computer store, they probably have them in stock. Otherwise, just give Chad a call and he can fix you up.

Mr. Geg,
Do what Steve said: Call Chad. Your question will be quickly and efficiently answered.

geg: I am sure Chad has the pumps available. These pumps are not industrial rated, they are just used for cooling overclocked pc's. If Axiom doesn't have one, and you are near a actual pc store they could probably fix you up. I'm not talking about a Best Buy, but a actual computer store.
Just a thought, did you take a coolant line off and then turn the machine on to see if the pump is working?
Just take a line off at the spindle and put a tray under it so you don't spill coolant all over the spoil board.

Yes, my coolant pump and fan went out over a year ago. I was in dire straits because of a paying job (which I don't have a lot of) so I went down to Lowes/Home Depot with a sample of hose and got a 5 gallon bucket, a fountain pump, and various fittings and hose to make a coolant system like some of the other cheaper systems come with. I put 2 gallons of coolant in the 5 gallon bucket, and it worked well enough all through last summer that I got lazy and never bought the computer fan and coolant pump that would be the replacement. I couldn't get metric tubing for a replacement, but I was able to find a standard size that was close enough that I could put on with no leaks. I keep thinking I should fix it, but only think about it when I turn on the fountain pump.

geg: The system traindriver is now using has been used on many cnc machines for a long time and work quite well. The Laguna's use that system, and uses the same Rich controller used on the Axiom machines. The fountain pump will actually circulate more coolant than the pump Axiom uses. In fact, there would be no radiator needed when using the larger pump because of the volume that larger pump has. The Axiom simply has a more compact and closed loop system that is sufficient for the spindle.

You guys were absolutely right. I not sure what I was thinking but I finally called Chad and he had me one the next day! I should have realized after all the times I've called him in the past over stuff that he'd come thru, again. My Bad!!!

One other thing to consider: Bubbles. I had bubbles in the line and after reservoir replacement (mine had a huge crack in the side from something - very weird) I could see them enter the pump...but not exit. I knew it wasn't circulating properly. One of my son's friend who build a lot of computers with liquid cooling systems suggested I set the spindle speed to zero, pull the spindle OUT of the holder and turn it sideways, then turn the spindle "ON" using the hand controller (still with 0 speed). This will activate the pump and allow the bubbles to be pushed through/around the various baffles in the pump. After a minute, I slowly rolled, pitched, and yawed the spindle in all three axis to ensure there was no chance anything was stuck (all motions produced more bubbles).
I actually think this could be something happening in transit and part of the setup process should be to "burp" the spindle to make sure there is good flow...or install a flow meter from the factory (hint hint).
Good luck!

My question is: How long can the spindle on the Pro-8 Pro run without coolant? Apparently, all the coolant leaked out some time ago and I didn't notice. I could see that it was a slow leak as there was slightly damp sawdust inside the heat exchanger. Most of the jobs of late have been light duty, but a few involving heavy cuts over several hours at a time. Does anyone know if there is a high temperature cut-off either in the spindle or the controller unit? Last night, I was running a 3-D job, 1/8 ball nose and .02R tapered ball nose (both really light loads) followed by a 1/4 EM profile cut (5 minutes at most). The clearing pass took almost 3 hours and the final pass about an hour. I was noticing the spindle getting pretty warm, but not hot. I felt the hoses coming from the top of the spindle and they seemed cool. Also, did not notice any heat coming from the heat exchanger fan outlet. But the job was running late into the night and the next day I looked into it. Reservoir dry, damp sawdust, but no drips. Pump motor not running when spindle engaged. Couple things for me to check tomorrow:
Machine is 24 vdc. Pump I ordered is 12 vdc I am hoping to check voltage at pump connector tomorrow and find 12 vdc. If 12vdc found, then not sure it is even necessary to check function by applying separate 12 vdc supply and see if pump runs.
So, question remains: How long can the spindle last without coolant? Thanx

Until recently, there had been numerous vendors on Amazon selling the SC-300T Cooling Pumps with shipping within just a couple days.
Unless their supply has dwindled much like our own...in which case, they'd have to come from Syscooling directly in Taiwan or China. While there are both 12V and 24V items on the machine...the cooling system should be running on 12VDC only.
With regards to the spindle health: As long as you are not purposely pushing the machine, the spindle should be fine. We had designed the system using a thermocoupling which is intended to shut the spindle down and provide an alarm code...if the system reaches an specific temperature.

Thanx Chad. Re: over-temp sensor: As I expected, you guys have everything covered.

I just finished a 12 hour job tonight and noticed that my spindle was running warm and it did occur to me that maybe the pump had gone out (AR 8 Pro - purchased a couple years ago). The job was too loud to hear if the pump was running, but after reading this, I'm going to take a closer look at it tomorrow.
