- Making a probe work
Experiment
The 20180811a experiment showed that it's possible to get some echoes from a probe. It yielded some echoes:
Let's see if we can make it move
Yes!
With an update of STEP on a DRV8834 pololu driver, it moves. However, the motor is to be plugged in a specific way.
It seemed the bobins of the stepper where:
- Grey (2) + Purple (1)
- Blue (4) + Green (3) (as per images below)
To have it move, the setup needs to be as follows
- A1: Green (3)
- A2: Gray (2)
- B1: Blue + Purple (1) + (4)
How it was plugged
