Yes, and the velocity output from an encoder module to tell this 
controller how fast the spindle is turning.  Its the feedback signal to 
the PID module.  The actual lock step that drives the z axis is 
determined from the position output of this same encoder module.

There is a spindle speed limit when doing the coarser threads, in the 
form of the z axis MAXVEL. But I'm not sure it squawks if you exceed it, 
so don't exceed it.

The speed command is an analog voltage, so a simple 
optoisolator won't work.  There are isolated spindle speed 
controllers that use a PWM scheme on an optoisolator and 
then convert to voltage on the isolated side.

Since I saved them on this  machine and have not made sshfs live yet, 
Thats best done by bringing the card in, plugging it into a reader to do 
the transfers.

I have had it working a time or three with the buildbots old 2.8.0-pre, 
but its quite fragile, never crashing at the same point twice.

I've rsync'd that out to a backup drive from the card that was in it for 
the last 4 or so days, then when this new finally booted to a usable 
screen, rsynced it back in order to get the most recent edits in place. 
ANAICT, everything works, but its very, very fragile, freezing up at the 
drop of a 4-40 screw 10 feet away.

I was going to print the README.md, and build according to that, but 
found that while the package manager says cups-client and friends is 
installed, its not usable as there is no /etc/cups/cups-client.conf.

I haven't sorted that basket of rattlesnakes yet, been sitting on the 
rider, trying to find my yard.  That, by the time I loaded the 3x5x1 
foot deep 2 wheeled wagon full of hedge trimmings stacked about 3 feet 
high, to haul it to the burn pit wrote a ~30~ to my back for the day, so 
the weedeating around the edges will wait till another dry day.

And its time (17:45) to round up something for dinner. So thats the 
status for today.  Thank you Bertho.

Cheers, Gene Heskett

As long as that controller is passably real time, which with an scr 
controller might be a problem since itr can't react any faster than the 
lines power frequency, I don't see why not. I have one with an 
opto-interruptor setup thats effectively a 268 counts per spindle rev, 
driving by a PID control setup, reacts fast enough to rattle the gears 
between a brushed 1 hp motor and the spindle of a Grizzly G0704, so the 
speed is fairly well controlled. But that has very little to do with 
rigid tapping as the 268 steps per revolution is what the (normally Z) 
axis follows quite accurately.  

I've a similar setup on The Little Monster, a 7x14 mini-lathe, similar 
horsepower but moving a 5" chuck, which has buckets of mass to reverse, 
so the turnaround time at the bottom of the hole can be considerable, 
particularly in terms of overshoot, so I have to drill the hole at least 
4 tap turns deeper, else the tap hits the bottom of the hole, followed 
by the sickening crunch of yet another broken tap.

I have a hall effect encoder ( 240 steps/rev) on an 11x36 sheldon I am 
just now bringing to life, and again, that nearly 8" chuck, and the 
turnaround ballistics of the vfd driving the 1 hp, 3 phase motor will 
also make me keep track of how much deeper I need to drill the hole to 
keep from hitting the bottom of it as its slowing, having reached the 
depth you gave the G33.1 in the call. I've developed some hal code that 
will tell me how much overshoot I have, but on that 3/4 ton machine, I 
don't expect to be able to tap at anything over 250 revs. Those are the 
gotcha's, but if the tap doesn't break, the rigidly tapped hole will be 
tapped nicely.

What I'm trying to say is that a common  A/B/X quadrature output encoder 
(it must have an indeX once per rev) even with much larger slices of 
rotation per step than what I am using, can and has done rigid tapping 
for several folks here. The quadrature gives linuxcnc the direction 
information on the next pulse output as it hits zero speed and starts 
the reversal.

Re: [Emc-users] tach/generator/encoder

[Greg Bentzinger via Emc-users]

The way I read the manual page 24 section H. It is saying the tach is a better 
option for fine motor control, but not required.

If you are using a spindle encoder as a tach source to have LinuxCNC control a 
+/- 10VDC connected between terminals COM and SIG (see figure 14).

As Jon stated you will need a spindle control board that is isolated on power 
and ground - This is not just talking about opto isolators.

That is a Cadillac of KB controllers as most will accept speed control - but 
not allow reversing without using an external physical switch/contactor and 
that is sensitive to switching under load.

Be careful - no magic smoke! - bad for your health and painful in the wallet.

Greg - Out yonder in Yoder.

Big problem with KB drives is they are NOT isolated from the 
power mains.  So, your source of the speed command must be 
isolated.  Tach generators are really just DC brush motors 
wound to be free of voltage ripple.  Maxon makes some nice 
small motors that make excellent tachs.  You can often find 
them surplus for under $10.

Re: [Emc-users] RPI saga continues - SPI probably solved

No, you need to pull the most recent source-files (hm2_rpspi.c and
spi_common_rpspi.h) from the mailing list (or the forum).

Login as pi user and put them in
~/linuxcnc-git/src/hal/drivers/mesa-hostmot2/

Then do:
$ cd ~/linuxcnc-git/src
$ make
$ sudo make setuid
$ ../scripts/linuxcnc -v ../../linuxcnc/configs/sheldon-lathe/7i90-axis.ini

That should run your sheldon lathe config. You may need to update the
config as needed.

Does the image I downloaded Saturday and wrote to an sd card yesterday 
have this stuff in it? I got sidetracked today, doing a poor man's 
set-true to the chuck, and getting it under a thou. Can't go any farther 
w/o reaming the bolt holes in the backing plate a wee bit. Thats pretty 
close, and I've no reamer kit.  Yet. Just one of several items I need to 
acquire, like a live center which I didn't get with it.  And of course 
more tooling, never have enough.

Back when I bought the ER-40 kit, someone said I couldn't use long 
workpieces with it, but it clears several feet of nominally 7/8" OD 
stock, so as long as the OD is no more than that, I don't see a problem, 
but I'll have to make a spider for the left end of the spindle, easily 
done if I can find some brass acorn nuts.

I'll see if I can pull the cover tomorrow and try the new sd card, 
Bertho.  Depends on the weather.

Cheers, Gene Heskett

Re: [Emc-users] tach/generator/encoder

[jeremy youngs]

Good day folks. Im waiting for ebay to drop this at my door
https://www.google.com/url?sa=t=web=j=http://spectechind.com/Documents/KB/KBMG-212D-manual.pdf=0ahUKEwjM6aSAtqnUAhUG3IMKHcT_CUgQFggqMAA=AFQjCNGFBaUXQadurcokpyECREPoUQtv-A=Pi3K5iam1Y-9UdVNt5mrew
. It calls for a tach/generator my google foo shows them to be very cost
prohibitive. I have so far only setup stepper system. I am using this as a
spindle drive on my mill 90 v treadmill motor. I want to be able to rigid
tap. My question is can I just use an encoder and have Linux cnc control
the position ? I think so but before I order an encoder I would like to
know . Thanks
Jeremy

Re: [Emc-users] Programmer for a serial EEPROM?

[Rene Hopf]

Hi,
for programming I can recommend the TL866 minipro, available from ebay or 
aliexpress.
works great, programs almost everything, and there is open source software 
available for it.
