Strange motor mix values resulting from Quatos

[DUKE40]

Hi,

I have measured ma Air Fram geometry and entered it into the quatos tool for calculation of the parameters.
The resulting values were imported into QGC and transmitted to my nanoHexa, but this is resulting in strange motor mix values, the sum of all values for toll are not equal to 0 and a warning is displayed.

How can this happen?
Attached my XML file

M4_NanoHexa.xml

(1.74 KiB) Downloaded 808 times

and the resulting parameters.

M4-NanoHexa-Parameters.txt

(5.47 KiB) Downloaded 757 times

Any help would be appreciated. Currently I am a little bit reluctant doing the maiden with these parameters.

Why do they not look right?
A is Port M2
B is Port M5
C is Port M6
D is Port M7
E is Port M8
F is Port M4

So it should be OK, or do the number 2, 4, 5, 6, 7 and 8 have different meaning in the config file than M2, M4, M5, M6, M7 and M8?

The rotations (+/- 1). You have 2 CW and 2 CCW next to each other.

Hi Max,

could you please elaborate?
Do you mean the file should look like:
<port rotation="+1">2</port>
<port rotation="-1">5</port>
<port rotation="+1">6</port>
<port rotation="-1">7</port>
<port rotation="+1">8</port>
<port rotation="-1">4</port>

If this is the case, this should not be a problem changing it, and having the parameters calculated again.

The order of the ports in the XML matters and should match your physical configuration. First one should be front or front-left motor (depending on if "+" or "X" layout), then continue in a CW direction to the other motors. So yes, based on what you've said so far, the new version looks more correct.

Did use the new order of the ports for calculation, but the result is exactly the same.
So there must be something else which influences the calculation of the Motor Mix as well.

For a pre-defined configuration you do not need the motors parameter in the first line.

Try this.
<craft id="NanoHexa" config="hex_x">

OK, I will try it this evening and let you know if it solved the issue.

Just changed my XML configuration file, got the parameters calculated, but again Motor Mix looks odd:
summ for Roll, mmRoll and Yaw is not equal to 0 and a red cross is displayed in front of the sum and warning when transferring the data to the M4 is shown.
Attached the new XML file I used:

I have no idea where I should look now, and what might be causing this, whihc is really meking me uncomfortable for the maiden flight.
