... month of study in vision system algorythm ... finally see a real utilizations ....

If the device does not have a built-in watchdog, I guess you could remove its logic
power with a watchdog controlled device.

When i set an out pin to TRUE after shutdown linuxcnc remains true
how can fix this except setting signals to 0 in shutdown.hal file.

very glamour design .... Real Tempered Glass is a touch of class .... with that pc you can really go to Mars.
Good work.
Bravo.    

Yes, that looks OK hardware wise. LinuxCNC will only enable the output when running
and any loss of communications will disable the output.

hello to all .... i read these pieces of code generated from gtp .... is valid or not??

--enable-qt6 flag exist??
 

do you or does anyone have any recommendations for a suitable pcie parallel port card which can support 9 input pins?

also, if i were to change the data transfer mode of the pcie parallel port card from say EPP to SPP or ECP or Ps/2 , how to acheive that?

I work on Windows 11 with Visual Studio Code, I haven't cleaned it, I don't even know how to do it.

Is the axis actually driving a chuck?

Analog will not change anything.

Why do you require such extreme acceleration?
It will lead to inaccuracies when cutting.
This is multiple Gs of acceleration at any significant
part radius (if this really is a normal rotary axis)

If you want to tune the axis, you need to setup halscope
with commanded joint velocity and following error, then tune
FF2 and I (FF2 will be in the 0.0002 region)  Too little  FF2
will cause a positive following error for acceleration in the
positive direction. Too high FF2 will cause a negative error
for acceleration in the positive direction.
'I' probably in the 50000 to 100000 region.

You will likely need to increase the following error limits
for tuning.

Here is a tuned A axis with 40000 degrees/S^2 accel and
10000 degrees/S velocity:



 


Note that the peak errors are about 1/10 of a step.

Failed on an image paste here, so trying again with an attachment.

I'd like to confirm that I'm connecting up my 7i77D correctly.
The I-J3-2 terminal here went originally to an optical isolator that was kept switched on by a watchdog timer that only runs when the operating system is loaded and running. The COR relay is enabled  by the On switch, and until this happens, nothing on the machine works, eg the servos relay cannot be enabled etc.
I am proposing to connect this same terminal to IO Output pin 0
mesact has written io.hal line as saying 
net estop-loopback => hm2_7i92.0.7i77.0.0.output-00
From my reading of the manual, the 7i77 will only enable this pin, when linuxcnc is up and running.ie the same as the original system.

Does this all look good?

Thanks

That looks perfect. Thanks for telling me about it!
