Half a mm seems like a lot, for a m4x.7x6mm screw.  Thank $DIETY the 
screws aren't that sloppy.

No doubt true Chris, but thats why, needing a few more than 50, I bought 
3 boxes of 50 ea. So they'd all be a good chance of being the same size. 
So far, those I've measured have been from one or 2 red ones under 
7.00mm. Crossed fingers at my age can be painfull, but I think I've got 
this one covered now.  But I didn't say that in front of Murphy. :)

Here is the 3rd one of those R8's I've made a key slot in. It fits the 
head of a m4 socket-head bolt, with a couple thou of clearance.

The Merican SC 1/4" 4 flute up spiral walked right thru it, at creep 
speeds of course. And of course pulling the tap out of the collet, crept 
out about 1/4" on the last of the 3.

Now I can have 3 taps of various sizes all ready to go for a given 
project. But I made 52 of the brass slugs, so it looks like I'll have to 
get with it and make a new box to keep my mounted taps in.  And stamp 
the face of the slug with the tap thats in it of course. Then the 340 
million dollar question is where the heck do I put it... :(

Re: [Emc-users] Korean R8's arrived

[Chris Albertson]

More accurate if you turn down the screw heads to make them 0.5mm
smaller.In fact if you want all your screws heads to have the same
diameter you have to turn them yourself.   I looked up tolerances a
while ago and it is abut 0.5mm on the head diameter.  Likely within a
batch they are all the same but if you buy more they high be
different.  So turn them to the minimum allowed head diameter.  I was
surprised the tolerance was so wide.

Way did I bother to look this up?  I printed a plastic part and the M4
cap screws did not fit in the counterbore.  Debugging the problem
found the ISO screw standard and the fact that plastic changes as it
as it cools.  One must allow for both.

Got the braces glued on, gave the titebond III an hour to get a grip and 
finished the Grizzly 7/8 R8 so its usable, but when I switched it out 
for the first of the Korean ones it sounded different when the tool 
touched. Went ahead and drove the machine with what should have cut a 
7mm wide "key", but when testing for fit, the screw head was half a mm 
bigger than the cut. Stopped the spindle, and the leading edge of the 
flutes of a 3 flute, very high twist SC mill I had sourced from ebay a 
few months back as part of a 2-4-6-8mm kit for about a $20 bill, were 
all shattered away for about a mm back from the edge. I can finish the 
cut with a dremel, but these things are HARDENED. And I only have US 
sourced 1/4" 4 fluter's left. I'll go waste one of those.  Or finish it 
with the die grinder, then try one of my 1/4" 4 fluter's on #3.

Which just proves that nothing is ever as simple as it appears...

EDM maybe? I can do that too, on the little mill.

Re: [Emc-users] One servo system

[Chris Albertson]

The comment to use psocketbeagle and MK if Linux is required is good.
I just looked up psocketbeagle and I don't see any network interface.
 Likely if you want a Linux based controller it is so you can access
it remotely. You might get a USB/Wifi dongle to work but it would
be better to buy a board with built-in networking if networking is
important.   But the pocket beagle could always use a serial line for
networking if all you need is a text window and a few file transfers.

If you don't need Linix then it can be much simpler (An Arduino would
work) but remote access is a very nice feature to have.  Nice enough
that I'd go with a card that has built in wifi.

Re: [Emc-users] One servo system

Hi Alexander
I decided that this is the way to go. I did see that there is some talk 
that not all kernels are supported on the board.
Is there a place where I can go look to see how to get this board setup 
with MachineKit please?

I think a simple real-time component should also do the trick in case
the ladder logic component (it's also RT right?) does not work for your
application.

The PocketBeagle also has a PRU like the BeagleBone, so step generation
or encoder feedback should be fine.

 It will have to be headless so I would imagine that I will be using
 ladder to control the system with.

 The track length is 6m, a button is pressed and I accelerate to 8m/s 
and

 stop at the other end waiting for a command to do the same in the
 opposite direction. Machine must home in the one axis on demand as 
well.


 Would the ladder logic route be good enough or are there some other

Word wrapping broke the link, I think I fixed it.
Note the arrows now surrounding it.

Or, once I found it, pasted from pale moon:



Thats the same price I paid. But I see this sale claims .0005" TIR. The 
sale I bought from claimed .00016" TIR.

I've made mounting pillows for the ER-40 adapter I bought for the lathe, 
an r8, chucked in an er-40 collet, with a 7/8" slug in the r8, and 
pulled about 50 thou into the ER-40 collet, seems to be a good grip.  

The pillows, made from Mahogany, cut into end grain, but before I clamp 
it down, I'm going to glue on some oak or ash strips under the cutout to 
help prevent the mahogany from splitting because it will have a tight 
grip. Hopefully that will allow a carbide tool to make the slot for the 
m4 socket head bolt that should lock the brass tap carrier slug from 
rotating in the R8. The one I tried prior, the whole thing slipped on 
the table, but it looks as if the carbide tooling can cut it once I get 
it mounted firmly. I cut into the end grain because that direction 
should offer the best crush resistance when I tighten the rest of the 
clamps down. Theoretically.  And a heck of a lot easier than carving up 
a huge block of more $ alu.
