Here are the links to the version 4.1 (provisional) in Automation:

And finally Automation also has a real documentation files:

The version 4.1 it's completely different than previous.
Ci sono i Breakpoint, i Watch, the FullsScreen, the Select-Case and many other new instructions.

This little program of automation should help, It produces random movements XYZ very similar to your example.
If you need to edit it to add the comparator location Call me and I'll help.
The idea would be to be able to get the error even without Theremino CNC and then delete a large part of possibilities from research.

v1 = 0 		' Random Minimum
v2 = 10		' Random Excursion

v5 = 1		' Counter start
v6 = 50		' Counter end

Label MainLoop
	Gosub WaitAllMotOrs
	Slot(1) = v1 + v2 * Rnd
	Slot(3) = v1 + v2 * Rnd
	Slot(5) = v1 + v2 * Rnd
	v5 = v5 + 1
	Print v5 & " of " & v6
	If v5 >= v6
		Goto End
	EndIf
Goto MainLoop

Label End
	Slot(1) = 0
	Slot(3) = 0
	Slot(5) = 0
End

Label WaitAllMotors
	Wait Seconds 0.1 ' ---- ensure motors really started
	Label WaitAllMotors2
		If Abs(Slot(2)) + Abs(Slot(4)) + Abs(Slot(6)) < 0.01
			Return
		EndIf
	Goto WaitAllMotors2
' End of WaitAllMotors

OK, for even answer me pleasure to some questions and shake some more’ the field of action (and forgive me if I repeat some questions maybe you've already answered, I have many things on my mind and I do not remember everything, and then it is good to repeat in different words).

1) Have you tried using a different machine to see if it does too?
2) You may even shorten codes, for example, making only ten lines that make 0.1 mm error one o'clock?
3) You could eliminate any line does not strictly necessary, eg X0 Y0 Z10 and G4 and M30) and only use the G1
4) Could (as I wrote to you) As an example also in automation that does exactly the same movements, and who is wrong?

And now let's focus on what we already know.
I tried your example XYZ and end slot 5 The Z was perfectly zero.
This should be totally excluded from the problem Theremino CNC.
So if we wrote a code in Automation (Three RND functions that drive x, y e z) He should also make mistakes

second step
The firmware of the Master is the three axes totally independently so it should not change anything if we move only Z or X,Y,FROM

Conclusion
I can not think of any possibility.
We must do other tests to isolate the problem better.
Please try another machine.
I would help with my cutter but it's too slow (700 mm/min) to run your code in a reasonable time and then I have little time.

What happens somewhere RESET the Master module caused by voltage drops?
But they should also make mistakes the other two axes…

You tell me that does not happen with automation…
could you please make a Gcode with only the vertical axis and that does exactly the same operations up and down an automation program and then compare them?
E (if one of the two causes errors and the other does not) then maybe you could send them to me that both of them I also compared.
(maybe there is something that you consider harmless and yet it is not)
