I've added a Fogbuster system to my Avid CNC Router. In this video, I show you the overview of the system and how I'm using a small airbrush compressor in place of a larger compressor.

I've not got any CNC stuff, but the mention of airbrush compressors brings back some happy memories. Long before anything digital existed, long before Gimp and Photoshop and Inkscape, airbrushes were THE way to produce cool graphics. Incredibly hard to do well, slow and frustrating, but with a few years of practice (and a great deal more skill than I possess) you could get some astonishing results. I wasn't a professional artist and haven't got much talent, but I've still got my old Iwata HP-B (independent double-action) brush and a pretty decent silent compressor (ultra-smooth delivery of dry, filtered air is vital). I still paint the occasional weird Dali-esque landscape populated by little squiggly amorphous blobby bio-creatures. It's fun, but a bored 10 year-old kid with a PC could probably produce similar images in 30 minutes. But it wouldn't be the same. I ought to do something for KZfaq, but I'm too busy watching KZfaq.

We use the Fogbuster on our Tormach at work. It's critical for cooling and evacuating chips when using endmills 1/8" and under! I like your idea to use the airbrush compressor!

Just out of interest, how come you don't use flood coolant?

@@samuraimachinetools We didn't like the mess it made regarding cleanup and the machine rusting afterward. I suppose we could have looked harder for a better coolant that didn't cause rust. For now we just use a concentrated water-based solution.

what was the rough tube lengths? I am going to do a similar setup, but guessing fogbusters default 5' hose lengths will be too short. (4x10 avid pro). And... is the AL table necessary - can you not mount the vise directly to avid table, assuming you add additional cross members?

nice work! just wondering if you have tryd ethanol and if so how you find it compared to the isopropyl. i have the later and although most seem to use ethanol, id rather use what i have if its the same same but different type of scenario. thanks

Do you have any issues with getting the coolent on the MDF? I have a completely MDF bed and am slightly worried that it will cause the MDF to swell up.

@RobertCowanDIY 4 жыл бұрын

That's why I have a hybrid bed (1/3 aluminum, 2/3 MDF). But I'm using isopropyl alcohol for coolant, so it's less of an issue with the MDF. There's very little 'moisture' after the cut. The chips are dry and it evaporates quickly (which is why it's good at cooling off the chips and cutting tool).

I use Kool Mist 77. It's OK I guess. Not bad enough for me to consider switching, and good enough to get a decent quality finish.

Very nice video, many thanks! I am now looking at the schematics diagram for AVID's CRP850-00E breakout board. The FogBuster's solenoid switch requires 110v (default) but it is also available in 24v, AC or DC, 220v. So, I would imagine I need to take the 5V digital output line from AVID's breakout board (Relay#1, terminal 17/18) and send it to an external MOSFET (between AVID's board and the solenoid switch) for controlling the solenoid switch at 24v. Or use solid state relay instead for AC control of solenoid. Please could you let me know if I understand this correctly, and if this is the setup you have? Any advice will be much appreciated. Many thanks. AA from England

@RobertCowanDIY 2 жыл бұрын

I just used one of the AC outlets on the unit. That was the easier way, since using 5V logic to control a relay to control a solenoid is a lot of extra steps. There are two controllable outlets on the bottom of the main control unit and I just used one of those.

I use isopropyl alcohol. It works more as a coolant rather than lubrication. Works well for aluminum, I haven't cut steel on the machine yet.

@@RobertCowanDIY I'm building my Avid Benchtop pro 2X3 right now and just ordered a fogbuster thru the Tormach site. Tormach says not for use with alcohols. Have you run into any long term issues using IPA? I'm wondering if there is a materials compatibility/lubrication/corrosion issue or if they are worried about fire hazard. They also say no pure water so that sorta leans toward the former.

Nice video Robert. After doing a little research it looks like IPA does have a pretty large benefit for cutting aluminum, and I really like the idea of something that evaporates because I also have an AVID CNC machine that I use mostly for woodworking and I don't want cutting oil all over the place. I tried to find info on the flammability risk of this. I also have a large dust collector (1200 CFM) on a dust boot and I am kinda assuming that the low amount of IPA fumes in the very large flow of air makes it non-flammable. I was wondering if you have any data or information to back that up? I don't want to burn my shop down :-)

@RobertCowanDIY 3 жыл бұрын

This is not scientific, but in very low concentrations, it should volatilize enough in the dust collection system that there wouldn't be enough to actually ignite to cause a problem. You'd be mixing a VERY small amount of it in a large volume of air, moving at high velocity, I just don't see it causing an issue. I run it into my dust collector, and I have yet to have an issue. YMMV!

@@RobertCowanDIY Thanks Robert. Thats what I figured too. Just like everyone getting exited about static electricity causing an explosion in their dust collector pipes just because grain elevators blow up....very different concentration levels.
