Delay between THCarcon_emulation and start of the motion

[cncdrive]

This is the short video.
https://www.dropbox.com/s/6ym4uw1vkqfbwpl/TestPauseBeforeMotion_edit.wmv?dl=0
In this cutting pierce delay set to 0.3 second, but the delay occurs after the pierce. It is clearly seen that the controller has already passed in the cutting mode, but the motion has not yet begun.
First cut is correct because in my opinion there is a delay between M3 and THCarconsignalon_emulation (time for initial Height sensing procedure).
On the next cuts was Skip IHS function and torch moved on the cut height immediately after M3.

I've checked the video, but the g-code view is too small and video quality is too low, so I can't see what's in the g-code lines.
Could you please post a small part of this code? It would be enough to post a few lines only where the pause happens and also please let me know the number of line where the pause happens.

Thank you Balazs!
This is the video from my customer. Tomorrow I will try to send code to you.
it is not clear for me why this problem issue very rarely on my PC and constantly on the my customer PC.
I understand that this problem is very difficult to identify and solve.
I will continue testing tomorrow.
One question - buttons 536/537 are momentary or triggered? I mean if I am push on the 536 button and hold - ArcOK emulated and if I am release button - ArckOK stop emulated? If yes, what is the best way to call this buttons for start/stop emulating - repeatedly or one time when need to make emulation?
Thank you!
Also can you check - Cyrillic font (Russian) does not display correctly in the G-code editor and in the GCode box.
The name of the program was "Крепление двигателя 6 мм"

Hello Balazs!
I am make the video on my CNC PC. For the purity of the experiment, I remove the Neuron plugin from plugin folder. https://www.dropbox.com/s/q6qvzfem57zd0q2/Test.wmv?dl=0
On the screen there is a rect BLUE LED "ArcOnEmuLED" number 237 "THCarcon_emulation". This LED lit when I am push on the 536 "THCarconsignalon_emulation" hotkey button and turn off if I am release this button.

I am load program and start with THCON. You can see pauses between LED ON and start of the moves. On the hole I am any times release and then push on the 536 button. Motion was stopped and then continued without pauses.
But pauses always present on the start of the every cut (M3 command). Also if I click on the 536 button in 2-3 seconds after then M3 issue - no pauses.
Interesting fact:
This video was captured with program CamStudio. If I try to use to capture another program (FastStone), rendering of the ToolPathView slow down during program execution, but the pauses disappear. They appear again after then I am turn off capture and restart the UCCNC.

This is the program:

Andrew,

Thanks for the infos.
I've tried to reproduce the issue on my system, but it seems I can't, I mean there is no pause on my system with your code.

Can you try one more thing please is to configure the THC arcon emulation signal (code 536) to a hotkey and press that hotkey button down and keep it pressed and run your g-code,
so the THC arcon simulation signal will be always on, because you will keep that button pressed.
And check if the M3's still causing a pause this way?
What I would like to see from this is if the M3 causes this pause, because if it will still pause with the THC arcon simulation signal is always on then the M3 itself is causing the pause and not the THC arcok simulation signal.

And I've asked this one already, but could you please verify that the spindle on M3 time is set to Zero?
I've attached a printscreen and marked that setting, because that setting is by default 1000msec and with that the M3 waits for 1second before reacting to the THC arcon emulation signal,
so please make sure to set this to 0.

No changes. I am constantly pushed on the 536 button. Look on this video. Delay value ~ 3 seconds

One thing I do not see yet and forgot to ask about, sorry is could you place a SpindleCW LED (LED number:50) on the screen next to the THC emulation signal LED.
And also place a LED with LED number:21 which is the dwell to see and make sure the issue is not that a dwell is going on.
I would like to see if the spindle goes on slowly or if the controller waits after the spindle already went on.
Could you please make this and shot a video?

I am added LED 50 and 21. Now from TOP to Down - ArcONEmulation Led - SpindleCW LED - LED number:21 which is the dwell
https://www.dropbox.com/s/nt5dqzrcfsvb09c/Test3.avi?dl=0
CpindleCW Led turned on on the M3.
No dwell time - led 21 always turned off
As I said, this problem occurs intermittently on my CNC PC, but always on the my customer CNC PC.
I am just start FastStone Capture program for prepare capture and after that all works fine. I am not understand why????
Look: https://www.dropbox.com/s/w1ws3ps79xedlst/%D0%92%D0%B8%D0%B4%D0%B5%D0%BE_2016-11-26_181927.wmv?dl=0

Balazs, this is the video how I can solve this issue. This is a Magic.
When I am start capture via FastStone problem gone. (It just was found out by accident when I wanted to record video of the problem)
https://www.dropbox.com/s/9p9v79h93yddo4u/Test5.avi?dl=0

Also Pauses issued when THC future disabled.

Andrew,

Wow, that is strange.
I've talked to my API developer collegue and we agreed that this looks like somekind of timing issue.
I mean what could the capture software change for the UCCNC is basicly nothing, but the capture software probably loads the CPU,
so what could happen is that something happens slower than without the capture software running.

My collegue asked if you could add also the idle LED (LED code 18.) and the Buffer field (number 884.) on the front screen?
He said it would be useful information for him to know what is exactly happening, if the controller went back to idle and if the motion buffer is empty or not when the system is pausing.

Hello Balazs!
The video ready https://www.dropbox.com/s/41ed89b1pab392w/Test6.avi?dl=0
Bottom LED is IDLE (code 18) and on the right Buffer field.
As always when I am start capture program issue gone, when I am close capture program the issue is back.
