I have an NM135; I also bought a rather large aquarium air pump to blow chips, because my air compressor was shaking the building. The aquarium pump works pretty good. Anyhoo, I'm getting tired of plugging and unplugging the 120VAC air pump all the time, so I want to connect it to my mill such that it'll turn on and off with M8/M9 commands.

I can hear a relay clicking on and off inside my CD300 controller whenever an M8/M9 command is issued under mach3 - so that's good. But a quick survey of all the unused electrical connection blocks in the back of the mill itself using a voltmeter yielded no changes with relay clicks. So where does one connect the flood or mist pump?


Asked a simpler way: for anyone who bought Novakon's flood coolant system - where do you connect the pump?

There's a 110 outlet in the back of the machine that should respond to the M8 and M9 commands.

I can't find it. Attached is pic of my mill. Can you steer me to where your outlet is? And what is your outlet connected to?



PS: I'm going ahead with building a tap attachment for the NM135 - I'll let you know how it goes.

Oops... forget it. We have different controllers, so the back of my mill is a little different than yours.

A little off subject but is the Novakon coolant system a flood system or just a mist system. Are all of the steppers sealed?

Thanks,

It's just a liquid pump. Mist systems are "air" powered. You will need a compressor to do mist. You can purchase a number of mist systems ranging from $20 to $200.00 depending on your needs and pocket book.

Personally, I like mist better than flood on the 135's because, unless you have a watertight enclosure it can get real messy real fast. Also, I don't see how you could keep from damaging the electrical components like the exposed micro switches and possibly even the rear circuitry.

Maybe someone else has solved the problem that could comment on this.

Here's my partially-completed NM135 enclosure. I plan on it being near-airtight when complete, mostly for noise reduction.
Still to do:
- door & seals (door is front & roof)
- ventilation
- cable egress
- caulk inside joints
- Al angle over the edges
- maybe a sheet metal insert to guide coolant back to the tray.

gleas, I can't see how any coolant can get inside the back, so I'm not worried about that. As for the limitswitches, I planned on a flimsy cover.
