About 12 u-s.  Worst I ever recorded was 200 u-s after pokig around the 
planet with firefox for about an hour. But that is not as important as 
you might think as both x and z are now 3 phase stepper servo's so they 
haven't much to worry about even with bad latency because of the rubber 
between the stepper drivers, which are in the mesa 7i90HD interface 
card.  So the servos are the coupling between the stepper driver and the 
stepper itself. The advantage is that it only uses enough amps from the 
supply to keep it running smoothly. So the steppers run zombie cool, and 
with near total silence.  Watching it run a program is a bit like 
watching Casper The Ghost, its so quiet.

I acquired this lathe with a broken compound, it fell over long before I 
got it and landed on the compound crank, bending the spindle a few thou 
from the sudden stop with a bison 3 jaw chuck mounted, which I've since 
reground and it all runs true now. So now a QCTP is sitting on a couple 
pounds of cast iron. I cut from the sprue of a white truck wheel, we 
make them here in Weston, holding the TP a its normal height. It is so 
solid there's very little tool chatter either. I don't miss the compound 
since Linuxcnc IS a better compound than it ever had, doing far more 
accurate angles.

So this is a position servo. Very similar to mine currently.
I have an idb module which does an Inverse Dead Band between a-output and 
the pwmgen.value, with the amount at 9.5, about 2 short of making it 
hunt.

That idb gives an offset in the currant value according to the direction, 
which helps to cancel the brush and bearing friction. The pwmgen is 
still pinging the driver about 7% when the motor has stopped. From 
either direction. I need to set the DEADBAND accordingly, as the idb 
module, when in balance would then shut the pwm off completely. That's 
the theory anyway.

Thanks John D.
Stay safe and well.

Mine is PMDC with a 24 volt Estate gate motor that has a quad encoder on 
its butt, fed by a pwmgen in mode 2 driving a teeny little board with a 
pair of BTS 7960's on it for a full H-bridge. Rated at 27 vols and 43 
amps, this 100 watt motor generates zero heat in the BTS 7960's

I doubt if its anything like the Bergerda's to drive. Are you configured 
as position or velocity? If velocity, I'd be interested in your .hal 
file.

Thanks John D.

I don't have a pid loaded in either of my machines that are running a
vfd. The vfd is stiff enough it doesn't need fawncy controls.

The only reason I have an encoder on the sheldon lathe is for G33.1 and
G76 support. Both of those slave the z travel to the spindle, what ever
its running at doesn't change more than 2% under cutting load for G76,
and maybe 5% for a big tap doing rigid taping. G76 also slaves the x to
the programmed G76 cutting depth. On the sheldon, a pwmgen feeds a
spinx1 which controls the vfd. Not even an d/a except the spinx1 because
I run the pwmgen at a rate thats above the bandwidth of the spinx1.

You get far better results by properly tuning the vfd. OOTB they suck
huge dead toads thru soda straws. With a pwmgen getting the speed
signals from motions spindle output, that pwm fed to the spinx1 along
with the dir signal, and a bit of hal sequencing, my Sheldon, turning at
100 revs in high backgear, and low belt position/speed, I can do a rigid
tap move, and measuring the overshoot at the bottom of the G33.1 move,
is .25 turns. That's with a nearly 40 lb 8" 4 jaw chuck mounted. Who
needs a pid?

That .hal file is attached. Cherry pick with my blessing. Sure its a
rpi4 file, but its running a Sheldon lathe that after stripping the
stuff linuxcnc doesn't need, and putting in decent ball screws,
still weighs around 1350 lbs.

Stay safe and well, John.

Which VFD  is it? In some cases the LinuxCNC ModBus drivers let you do
all that the OP panel would allow. Though sadly in some cases you
can't enable Modbus without the OP.

I've got 2 speed pulleys on mine 2000 and 4000rpm. Just want to try and
fine tune the rpm and see if there's a way to soften the acc/dec without
messing with the vfd (don't have the removable programming panel). Plus, i

Hi Gene, 
In this reply I've pasted the 3 axis HAL information below.  I realize now I'm 
not the john you were referring to but maybe this will help?

Hi Gene,
Not sure if you are asking me but below your message are three axis.  
The Y is step/dir to an HP_UHU DC Brushed Servo Drive.
The Z is the step/dir to Bergerda AC Servo drive
The A axis is a harmonic drive 4th axis AC Servo driven with step/dir to the 
STMBL drive (just like Andy's).

[Emc-users] Q for Big John Thornton re your servo tuning doc

I'm still having tuning problems with this thing.

Reading thru your doc it finally dawned on me that you are tuning a 
velocity mode servo, while what I had cobbled up was a position mode.

Trying to fix my hal file to work with velocity has been an even bigger 
headache.

So here I am, hat in hand, wanting to see your .hal files section showing 
how its hooked up to be a velocity mode servo.

Thanks John.

Cheers, Gene Heskett

My response to your question is the last line of my post but here's the 
background.

If you've ever had the experience of working on an IBM 360/370 series and 
written programs using PASCAL you'll have discovered an interesting problem.
The PASCAL statement 
if ch in ['A'..'Z'] then begin ... end; 
won't work right.
That's because the compiler generates code that does the following test 
(written now in C for example) .
  if ((ch >=0xC1) && (ch <= 0xE9)) { ... };
Needless to say the PASCAL is easier to read when you understand set notation.

Trouble is, the IBMs used EBCDIC for character representation, not ASCII.  To 
write this in PASCAL and in C is done correctly like this:
IF (ch IN ['A'..'I']) OR  (ch IN ['J'..'R']) OR (ch IN ['S'..'Z']) THEN BEGIN 
... END;

In C (or in PASCAL) to use the hex values you would write it like this:
if (((ch>=0xC1) && (ch<=0xC9)) || 
((ch>=0xD1) && (ch<=0xD9)) ||
((ch>=0xE2) && (ch<=0xE9)) ) { ... };

Yikes eh?  Notice the gaps.  If the ch had a value 0xE1 then the all inclusive 
test from 0xC1 to 0xE9 would pass even though the ch variable has an invalid 
character.

No move forward in time and Embarcadero changed the OBJECT PASCAL (Delphi) 
language in one fell swoop breaking thousands of programs and who knows how 
many man hours were required to fix it.

The type CHAR was always 7 bit ASCII and as programs became more international 
the WIDECHAR was introduced to handle 16 bit character sets and special 
characters or symbols like the German umlaut.

And then suddenly a char was 16 bits and an ANSICHAR was 8 bits.  Every program 
out there that expected CHAR to be a 7 bit ASCII character broke.  Most  of the 
time it didn't matter much because if it was a desktop screen application the 
OS took care of a lot.  If you dealt with weigh scales and serial ports or any 
other hardware device that sent 8 bit characters over a UART based serial port 
it was serious.  Or reading a text file created by a different OS.

And with the advent of 16 bit characters we can now have all sorts of values 
for what to the average eye looks like a '-'.

And the locally-compiled version is yet a third variant:

s32 out shows the current scancode without keyup / keydown markers.

That's a plain ASCII 0x2D minus / hyphen.

I wonder if asciidoc or dblatex that's munging the HTML output.  Maybe some
new version that needs a new qualifier to generate the minus sign rather
than the hyphen.  Looks like there's already a conf file that doesn't allow
replacements for the arrows.  Maybe there's another qualifier that has to
be used with the possibly updated software?

Looking at the source HTML on the server by ssh:
sendkeys.N.currentevent
s32 out shows the current scancode without keyup / keydown
markers.

Looking at the delivered HTML:
sendkeys.N.current−event
s32 out shows the current scancode without keyup / keydown
markers.

So, the  is being delivered as a dash...

Then that is converted to asciidoc (I think) and then to HTML using a2x.

But, it all works on my local machine, so doesn't seem to be inherent

Re: [Emc-users] HTML Help

2021-03-05 Thread Mark Wendt

What is being used to generate the HTML output?  Perhaps a character code
in the application is not set to generate the hyphen but instead generates
the dash?  Maybe someone changed the character set being used?

What screen resolution is the laptop screen?  Some laptops 
have really ODD screen dimensions and not all drivers can 
handle those. I've run into this before, a long time ago.  
Some online research might show that others have run into 
this issue on that laptop model.  Possibly forcing X11 to 
use a default (x)VGA driver might get rid of the issue.

[Emc-users] HTML Help

It has become evident that the online LinuxCNC docs in some cases (but
not all) are displaying en-dashes in place of hyphens in HAL pin
names.

ie, what should be a 2D is an E2 88 92

For example: http://linuxcnc.org/docs/2.8/html/man/man1/halui.1.html

has: halui.tool.length−offset.a float out
But should be: halui.tool.length-offset.a float out

If I (and others) generate the HTML locally we get the correct output.

Has anyone any idea what might be going on? It is more than just an
æsthetic problem, it means that copy-pasted hal snippets don't work.
