thanks, 6 core PC with one isolated = 5 available so that's right. i5 should be fine
What network card? is it Realtek?

I've been researching this today. Here are a few more obscure settings that may help where eno1 is the NOC name from ip a

Its an odd looking voltage plot.
I would look at the time after arc ok the THC is activated. To me it looks like it needs to be 2 seconds. I just can't see the setting I'm looking for.
Early activation could be disabled by the big fluctuations in voltage.

Use the 'Add a comment' box at the end of the 'Conversation' tab in the PR page:
github.com/LinuxCNC/linuxcnc/pull/3877

The discussion should occur on the PR. its up to the dev team, not forum users so you neet to convince the gatekeepers. Personally 80 files in one commit is too much to clearly understand and debug build errors.  Perhaps the component is in one PR and the sim in another.

No, it didn't

What aspects of Andy's carousel.comp have you identified as needing improvment, and/or what other features/funtions are you adding with this comp?

Do you have a github repository, or just keeping the current version of code uploaded to the initial post in this thread?

My Schaublin tool changer is extremely simple, with just a single input to open the tool change pneumatic valve, for a fixed duration, and then checking the next feedback pin went high. Cycling through until the target position is reached. I don't need much of the code like tool unlock, tool lock as that is all pneumatically sequenced.

I am not sure what to do about motion to a tool change position. Given the excessive size of my carousel, relative to the lathe envelope, and wide variety of tool geometries, tail stock etc I suspect it is safer to not automatically move to a tool change position. Do you have thoughts on that?
Cheers

PCW: Thanks for that, I'll consider changing kernel, or maybe trying with another pc.

rodw: processor: Intel(R) Core(TM) i5-8400T CPU @ 1.70GHz, echo $(nproc) prints 5.

pos is of course the number of rotations since zeroing on index. This is the main driver for
the synchronized move, the z-axis is being forced to follow pos.

Rotational speed isn't mandatory, but convenient to have.
You use rotational speed for the at-speed pin and is displayed in the gui.
I guess enc-frequency-scale should be set to 1/2000, so 0.0005, for rps.
For rpm 1/(2000*60) = 8.333333e-6.

Hello,
Is the Forum where discussion of new hal comp takes place?

On Github, on my fork there is a Discussion button
On Github in LinuxCNC.linuxcnc there is no button.
Google said the Forum was the main location for discussion.

Where is proper place to discuss?

My case is
  problems with package creation and a new comp.
 My comp builds and runs fine locally,
but a PR fails during package creation.
I hope a new push will fix the packahe creation error.

I'm not sure on that. pos = position so it implies reading a linear scale when you have a spindle, you want to measure RPM or RPS which a frequency resolves to with appropriate scaling. 

Hi All, 
The ohmic enable gets randomly triggered when laser is enabled. The wiring is as follows to the 7c81 board: 5v from bob , signal to 7c81 encoder pin direct, pins 3 and 4 to gnd of bob. Please help!

doesnt enc-pos provide an accurate speed.

I have these:
www.ti.com/product/LM331
but i never bothered to use them as the time is worth more than the price of THCAD.
Easy to use and can be plugged to parallel port with a single optocoupler.

Yes, inverting and decoupling. 
Wouldn't be surprised if there is a similar isolated SPI component.
Best if the ADC has some kind of free run mode. Otherwise the reading of a value can take too much time.
Was looking for a new value every millisecond, with as many bits of resolution as possible.
Have also used ADS1014 with similar good result.

Some clarifications before this goes sideways:
-COM0/COM1/COM2 are referred to serial ports, be it RS232 o other, usually.
-LPT0/LPT1/LPT2 and sometimes only P0/P1/P2 are referred to parallel ports, usually.
What are you referring to with COMn ?
Serial ports are pretty much useless with LinuxCNC, except for some stuff.
Parallel ports, also known as IEEE 1284, are used for machine control still, are perfectly usable with LinuxCNC, but have limited pulse rate capabilities compared to Mesa board.
Reasonable pulse rate or encoder pulse rate for parallel port would be 10000-20000 PPS, sometimes can go to 50000 PPS with a bit of luck/tweaking the BIOS.
At 3000 RPM, that is 50 RPS, so for a 100PPR encoder ends up 5000 PPS, and for a 1000PPR encoder it is already way to fast for most PC setups, see above.
Now convert that to mm/m, as you gave us no info about drive/gear/reduction.
After all that, yes, you can use a parallel port, yes it will work with encoders (2 max normally per port), and yes, you can lower the speed if you have higher count encoders.
But first, fix the wiring and get rid of interference/bad grounding.
