Hi Sascha and Bernard, which drivers are installed ? So much changes, I don't know which programme I should use ? Thisone I already have or a newer version ... . I'm already on connecting things together since yesterday; not easy with my job; really busy in this time... .
Teensy PCB Ardumower (T-Mow)

Sorry i am not clear.
Test with.
Speed max PWM 100
Speed ODO min=5
Speed ODO max=120
Do the motor calibration at the bottom of setting motor , so mower can know the ticks/sec and compute the max state duration.
After motor calibration check the max RPM value and adjust to your need.
@LaurentS
But you can test it with the blue drivers first.
Have you also tested the MOW motor? Mine doesn't work with your cable assignment, the traction motors work well with your cable assignment, better than mine, much quieter.
You can used the last Software from Bernhards Github.
@Bernard
I will test it, but the Weather is not the best.

I have a few more attitude questions.
I think I have set the ticks per revolution quite accurately. But 1 wheel always turns about 20 turns more. I have no idea why, so at 1 revolution it has a slight offset, at 5 revolutions it is already clearly visible.
Driving straight ahead for 1 metre also fits quite well, but at 3 metres it only drives 2.80 metres.
Mathematically I have 7.95 ticks/cm (1136/3.1415*22=7.95), but that doesn't fit at all. When turning 180 degrees, it only turns 90 degrees. I have now increased this so that it also turns 180 and 360 degrees relatively accurately.

It's strange, i take a look on my MI-632
Speed ODO minimum =5 ????
Sorry again but Maybe it's not clear in my wiki i try to adjust it :
do by this way:
perimeter of wheel = 3.1415*22 cm = 69.113 cm (it's the distance for 1 revolution)
ticks/cm = 1136/69.113 = 16.43 ticks/cm
Test with this value and adjust until you have 3 ML in the test ODO
When the ticks/rev and ticks/cm are OK you can adjust the distance between the 2 rear wheel
It's the last odometry setting : Wheel Base in cm
Measure and adjust until the test is OK.
Take a look at :
AzuritBer Firmware (English) – www.wiki.ardumower.de
Sorry again but it's not what i want to say :
I want that you test with a speed ODO minimum low (5) to have a correct braking at the end of the wheel rotation.
If speed odo minimum is set to 50 for example the motor don't brake a lot and take time to stop and go over the ticks end.
If speed odo adjust correctly (minimum possible to have motor rotate on grass) maybe 5 (i set it to 2 on my MI-632) , the motor brake slowly and stop at correct ticks end.
On the test ODO you need to see clearly the motor accelerate on 1/2 rev and brake on 1/2 rev
BUT it's normal that on 1136 ticks the test go over 10 or 20 ticks to stop correctly.

Wie sieht es denn zur Zeit aus? Sind die aktuellen PCBs ausgereift oder stehen noch Änderungen an? Hat noch irgendjemand welche abzugeben oder plant jemand eine Bestellung?
Was brauche ich?
Power_PCB_v107 und Teensy_PCB_v1.01 und???
Gibt es eine Liste was man noch alles benötigt oder was man nicht auf den PCBs verbauen sollte?
Wie ist der aktuelle Stand? Bei Git steht dass Brushless nicht unterstützt wird?!?
Ich wollte gerne einen Matrix Mow 800 umbauen...

Hier ist eine grobe Übersicht, was du an Kleinteilen brauchst:
