I understand and study the situation.
But I'm not sure because with automation vibration tests I performed at high speed even where I saw the steel table in obvious difficulty much to try to hold it with my 95kg. Yet he is always returned to zero.
The tests carried out with CNC Theremino were sweet in his movements so as to make almost imperceptible different dates settings.
Certainly I would not rule out the Master and his whole system because it works to perfection.
Then XY I do not lose steps and are coupled in the same way the structure.
I think… and if the position relative to the central core of the earth is different… If you rotate the machine on its side… Z will be fine and will lose X steps? (almost always the brain flips in and out of strange thoughts).
The engines have the encoders and according to the manufacturer performs and controls with precision the number of inputs received even under excessive strain.

“…The engines have the encoders and according to the manufacturer performs and controls with precision the number of inputs received…”
My intuition tells me that the problem might be in these encoders, that they are not simple stepper, and that under certain conditions mistaken.I had regular stepper before and the problem was the same.
I run another load test without trying with all those I have available.
Now it is also a whole new wired, with separate power supply.
I update you.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)Ciao,
on email Theremino there are gcode file.
I ran the test with movement only in Z.
tests carried out both at high and low velocities with precise positioning on the micrometer (nothing errors).
The XYZ file instead after work also marked a shift of .7mm.
even only by executing the last line xyz it is positioned on micrometer with .1mm error
The test was performed in a festive day with all the activities of the firm zone. A silence broken only by the CNC.
inverter , electrospindle and recycling cooling water turned off.
Greetings
Vincenzo
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 mistakessecond 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,FROMConclusion
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.
