I like the large airline fittings, P? I'd have to go look

One of the tool truck guys said you can wreck air tools by not giving them enough air, I do not know if that's true

I made a couple adapters and for small tools that don't need extra air I can still run them

But now everyone is going cordless, too

Yes. Quick-n-dirty:

The amount of energy in a compressed fluid is a function of the mass of the fluid and the volume of the fluid. Picture an air cylinder - when you feed it compressed air, the piston moves, the cylinder rod extends and the active side of the cylinder increases in volume. If the compressed air supply is flow-restricted, as the cylinder extends its volume increases, but the mass of air can't increase at the same rate. So the volume goes up, but not the air mass. Pressure drops, less energy is available to move the piston, so it stops moving until the pressure builds up again. Cylinder stutters and jams. An air motor will do the same thing - stall and stutter, causes a lot of wear.

Best analogy is a garden hose - a 10ft 3/4" garden hose will do a good job of washing your car. A 300ft 1/4" garden hose will deliver as much volume as one of us old guys with prostate issues.

New-Line Hose for the win!!!
I needed some 8mm, 4mm and push to connect fittings to set up the coolant for the mill so I dropped by New-Line at lunch yesterday. They had the 8mm but not 4mm or the fittings.
Just got a call that the 4mm and fittings are ready for pickup.

Absolutely excellent service.

Pic's when you can please David.

Of the coolant setup I presume and not the hose and fittings

What, films too expensive ?

 

[David]

Fittings. Wrong size unfortunately.

Spent some time working on the CNC router tonight.
I bought a new mini PC as the my Lenovo M900 just didn't have the horsepower to run the software. Best Buy had a decent mini PC for $199 so I went for it. Doubles as a decent shop computer.
Upgraded the UCCNC software to the newest production release.
Also added a new screenset that enables:
• Z axis Auto Zero macro
• Semi Automatic tool change macro that automatically zero's tools after a manual tool change.
• 3 Park Positions - Available from onscreen buttons, and can be called from MDI or g-code
• XY Probing Operations.

Yes but does it work????

Well we shall see. I have the toolsetter but I haven't wired it in yet. 3D probe is inbound.
Oh and I reconfigured the axis so X0, Y0 is front left corner.
And set a Park position to X0, Y330, Z0

Where is Z0 in the machine coordinate space? At the highest point the router can go? Then all movement down is minus?

 

[David]

Yup. Z0 is the top of the Z axis. Mill is the same.
Router has 168mm of travel from Z0 to Z-168 where the collet nut is on the table.

Yeah see at least your mill head goes up and down. Where your Z moves up to Z==0 my milling machine Knee moves down to Z==0

 

[David]

That totally messes with my head...
So for you Z travel up is a negative move because the spindle nose is getting closer to the table.

Yes. Knee moves up and Z gets smaller or more negative. On the CNC router Z moves down and Z goes negative as the distance to the table or work becomes less. Never really worried about it with the CNC router because I always used a 0.062" piece with a clip lead on the router bit. At that point MACH3 sets Z to 0.000 and after that all router actions go negative to cut.

But it's watching that bloody knee go what feels like the wrong way...

100% That would mess me up no matter what.

 

[jcdammeyer]

I have enough problems remembering why I walked into a room and what I was going to do. Much less thinking about whether the knee going up is a negative or positive direction.

BTW, @David, Yours isn't the only machine where the spindle nose doesn't reach the table. This is the HAAS VF-1

Travels	S.A.E	METRIC
X Axis	20.00 in	508 mm
Y Axis	16.00 in	406 mm
Z Axis	20.00 in	508 mm
Spindle Nose to Table (~ max)	24.0 in	610 mm
Spindle Nose to Table (~ min)	4.0 in	102 mm

Thanks! The Mill and I no longer feel inadequate!

And you don't need 220VAC 3 phase 70A service.

The old vf5 was the worst of the vf series at 7" nose to table. Didn't realize that until it was on the floor, and made it almost impossible to do any plate work. 4" isn't too bad when you factor in holder lengths etc, 7" was just unworkable.
