Err, Roland, if "it is fresh in their mind", why fullquote my entire
post in your reply? Does that not completely deny the freshness thesis?

And is it not far more user-friendly to juxtapose pro and con in-line,
as here, without relying on unreliable wetware memory?

That problem arises only when there is excessive quoting. When, as here,
only the germane point is quoted, there is nothing to scroll past, and
the minimal quote establishes the context of the response. And there's
no need to read backwards.

Granted, excessive quoting is too common on most lists. A good MUA does
much to ameliorate the issue, though. In mutt, 'S' skips quoted text to
the next block of reply in a flash. I also have mutt display quoted text
and reply in different colours, so not only the "> " quotation markers
differentiate.

Are we now conflating the sequence of reading separate posts in a thread
with the order of reading the lines in one of the posts???
I'm at a loss to see any connection.

It would surprise me if anyone does. We reply in-line in order to make
the post intelligible to those who do not read backwards - first, second,
or nth reading.

[Emc-users] Posting order

[Roland Jollivet]

I've thought about this, and don't agree. If people are following this
conversation, then it is fresh in their mind, and it's very easy to read
this post. It irks me to have to scroll down to find where someone actually
posted.

So emails should be answered 'reflexivly'. If, however, if one searches and
finds a thread that is two years old, then you would scroll to the bottom
and start reading upwards. Why should everyone post according to the chance
event that someone will read the post at some later date. A discussion for
for people participating, not for possible latecomers.

If everybody top posted, it would make life easier for all. But it needs to
be consistent..

Couldn't agree more. This ancient wisdom encourages consideration for
the reader - and so may admittedly seem strange in this century. In-line
replies, like this one, add a reply to a context. A top post is an
answer without a question or context - good for skipping as impenetrable
ass-backwards nonsense, IME.

Or ... is it the custom in some quarters to read from the bottom up?
It's the only thing which makes top posting intelligible, one has to
admit.

You're too generous there, I think. Catching up on a week's¹ mail right
now, there's nothing more useless than fullquoting, before or after.
A considerate poster chops out the stuff he's not answering, leaving a
"..." to indicate there's someone else's input left out of this part of
the discussion. The shorter the quoted text, the better. It is after all,
repetition of list traffic, and unnecessary verbiage to read through is
an unkind theft of other people's time.

I didn't check delivery, because amazon.com don't deliver to me anyway.

The point is that they exist on Amazon. From many vendors.

I went looking on their site for SSR's since I was there. But I have the 
relay, so I'll use it.  It also mounts on a din rail. And can be 
directly controlled by the 7i76D.  The idea is to leave the computer and 
interface on, and power down everything else with an F2.

Which Alliexpress SSR are you talking about?  The units I posted a link to are 
only circuit breakers and voltage/current monitors.  No external control to

Does exactly what I want. Thank you very much  Now to get that power 
relay hooked up to motion.motion-enabled.  But I also mowed the back 
yard, what I can get to with the rider, and my back doesn't feel like a 
fight to get the weed eater started to finish it yet today. I might be 
able to get started on the relay, but its also about time to change hats 
for my chefs hat.

That Alliexpress SSR looks good, even mounts on a din rail, but I got 
burned a bit on my last purchase.  Cheap enough but a 60+ day delivery? 
nuh-huh.

Thanks Andy.

And that reads like precisely what I want. VOLATILE_HOME in all 4 axises 
should do what I'm looking for.
Then I had better start the mower, its overdue and and I can feel rain

Routed it back to use the edge's true output, but didn't restore the 
output net, tried the setp while it was enabled, got told I can only do 
that while disabled, disabled machine and tried the setp true again, 
worked. Lets see what happens when I restore the net. Nothing, not even 
an error in the terminal screen. Signal is getting to all 4 pins, but I 
notice from halscope that I can't make it longer than 2 milliseconds. Do 
I need a delay for the disabling to get thru the system and tell 
everything so its delayed enough to work? Or would moving the edge.0 
addf to the bottom of the list, just before the 5i25 writes be enough 
delay? I'll go give that a shot but its looking like a pair of edges 
might be needed, with the 2nd one triggering on the recovery edge of the 
first one.

I just did some testing (latest master) and there is a message:

halcmd: setp halui.joint.0.unhome 1
halcmd: must be in joint mode or disabled to unhome

Pressing F2 then toggling the pins 0 to 1 has the anticipated effect.

But, there is probably a simpler way to achieve what you want.
Look at the INI option "VOLATILE_HOME"

setp wasn't allowed till I commented unhome1's out the the hal file, it 
was true till then. false when those nets were enabled.  So I did a setp 
halui.joint.0.unhome to true, no errors, no effect. * marker in dri 
unaffected. setp back to false, no errors, no effect.  Beginning to be a 
puzzle.  Your turn & thanks.  In the meantime I'll go setup the relay. 
But since with/out the net, its false, I'll go back to a plus out at the 
edge.0.out & recheck.

Halui runs in user-space, so you might have simply got unlucky.

I would try setting the pin from the command-line first, if you are
unsure of its operation.

Unfortunately, or maybe because I told the edge detector to only outout a 
2000 ns pulse when machine.machine-enabled goes false, but while its 
applied to halui.joint.3. unhome, neither polarity of the edge output 
resets the home status of axis 3, the rotary. Other that lengthening the 
pulse, am I doing it right?

.hal file snippets:
# now unhome when motion is disabled.
setp edge.0.in-edge TRUE
setp edge.0.out-width-ns 2000
net unhome0 <= motion.motion-enabled => edge.0.in 
net unhome1 <= edge.0.out-invert => halui.joint.0.unhome
net unhome1 => halui.joint.1.unhome
net unhome1 => halui.joint.2.unhome halui.joint.3.unhome

doesn't work? docs don't say which polarity to apply to the halui pins to 
accomplish the unhoming. I'll go make the pulse longer but it seems 2 
servo thread times should be enough.  halscope says its getting there.

I haven't ever had to change batteries in the caliper scales.  That's because I 
made little disks with capacitors and these are wired to the power supply and 
sit where the batteries were.  So the scales run from the Shumatech DRO.  I 
also have a spare DRO-350 and two of the newer 550s.  One built and one still a 
kit.  But the first one and the scales have been running for so long.  It's 
really the DROs that have lowered the urgency of the CNC for the mill.  Working 
from a drawing, which needs to be done regardless of whether G-Code is the 
ultimate product, I find other than for arcs the DRO gives me 0.0005" accuracy 
for drilling holes.

The Shumatech can do bolt circles or I use a rotary table for repeatability if 
the part is round.  These photos show that.
http://www.autoartisans.com/mill/XAxisBearingClamp.jpg
Now this could have been done on the mill with a  boring bar.  Even the outside 
could have been brought to the right diameter.  And CNC is a no brainer there.  
But with the ELS setting the depth I had the time to grab the camera and shoot 
it while it was boring without worrying about bottoming out and breaking 
something.
http://www.autoartisans.com/mill/XaxisBoringClearanceHole.jpg
The holes that match the bearing clamp drilled on the rotary table were done 
with the Shumatech.  Tedious but workable.

I will add an LED lamp back into the housing of the original lamp.  Project 
#42.  I use a Nikon D800 for photos and Video.

Probably.   The X/Y motors are KL34-180-90 with 3200 RPM max.  With 5 TPI 
screws that's 0.2" per rev and with 3:1 for the X and 4:1 for the Y I'd 
theoretically see 0.2"/3  (0.06667"/rev) for the X can go 213 ipm.  The Y has 
4:1 (0.05"/rev) or a max of 160 ipm.  But it doesn't have the same travel as 
the X so end to end time will be roughly the same.  And it has to move not only 
the X axis assembly but also the rotary assembly since this mill could have a 
horizontal mill attachment.

I either case, unlikely I'd be milling anything at those speeds.

Here's the drawing of the original G3616 electrics along with the extra ESTOP 
relay added and use of the second set of NC contacts.  Since these relays are 
all 24VAC it was easier to bring the second contact to the PC to signal ESTOP 
and use the ENABLE out from the PC to control the ESTOP relay.   Any additional 
big red buttons can also be DPST (NC) and put in circuit with the RD/GN/BK/WH 
wires.

As long as I have a jumper or switch across the RD/BK it runs like it did from 
the factory.

It's just a fancy circuit breaker that shows voltage and current.

My mill came with coolant but I've yet to use it.  I will also mount one of 
those misters.   I'll probably put a relay in series with the coolant switch 
and for CNC operations leave the pump switch ON.   However an ESTOP requires 
the coolant switch be mechanically set back to off before power is restored 
(see drawing posted above).  So I don't know yet what I'll do with all of that.

Where "selected" is replaced with the joint number I assume. Yes. Still

You bailed me out again Andy, thanks.

Homing is a joint thing, not an axis thing, even in 2.7.

[Emc-users] disappearing pins?

[Gene Heskett]

Greetings all;

One of the things I need to do is to unhome everything when motion has 
been disabled. I intend to us the motion-is-enabled to control all the 
external power, meaning when motion is disabled, the power to the 
steppers is shut down by either turning off the SSR's or disabling a 
relay to shut off the motion power all over the system. I am only doing 
this on the sheldon ATM because powering down a stepper driver also 
makes it forget which microstep it was on when it last stopped, slightly 
invalidating any stored home definitions motion may have stored. So 
obviously I'd like to force a rehome.

I know there is, someplace, a pin or pins to unhome an axis, or all 
axises, but can't seem to find it in a halmeter list or in a man 9 
motion.

Am I going blind, or has it been removed?

Cheers, Gene Heskett

Once cnc is running it, you'll never note the quill caliper needs a 
battery. My quill has been locked tight on the G0704 for years. Its just

Nice shadow, right where you need it, not!

I light from the side with a gooseneck, as I've found the head-on leds in 
most colonoscopy cameras do nothing but add detail hiding glare to the 
image, when I can get the ^%#& camera to work at all.  My camera  mounts 
on a dovetail for remove and reinstall repeatability, on the bottom of a 
spindle lock I made from 1/2" plate.

You'll be able to lessen the belt reductions I see, by large amounts once 
the ball screws are moving it.

Neat, but I've no casting stuff except for bullets. I cut that stuff from

I've not addressed that yet. Do have a big red & yellow switch though. 
Haven't found my round tuit since I was living in Rapid City in

Neat John. What SSR's contain that display?

I have a din-rail strip screwed to the rear edge of the 2x4x3/4 shelf 
hanging off the ceiling to hold the electrics. Currently has a relay for 
the spindle coolant pump mounted, and will have a 2nd relay to control a 
2nd power strip that everything for the mill is powered by including a
