Cannot get it to draw anything resembling a box about brachiograph HOT 7 CLOSED

OK using the bg2 object from bg.py gives much better results and points me in the correct direction. It might be worth adding a troubleshooting section. I assumed that since I bought the exact servos and made my arms 8cm each that it would be close.

I think that your issue is that one or both of your motors are going in the wrong direction.

In d945017 I fixed an issue where I had forgotten to account for the need to handle this.

You could try initialising the BrachioGraph with servo_1_degree_ms and servo_2_degree_ms, as described in https://brachiograph.readthedocs.io/en/latest/reference.html#the-brachiograph-class.

Also, unless your clothes-peg and the other objects in your photo are exceptionally tiny, I don't think the arms you made really are 8cm long - they look more like 8 inches!

Try initialising with:

bg = BrachioGraph(inner_arm=8, outer_arm=8, bounds=(-6, 4, 6, 12), servo_1_degree_ms = -10, servo_2_degree_ms = 10)

I have:

• added a new section to the getting started guide https://brachiograph.readthedocs.io/en/latest/get-started/drive.html#check-the-movement
• corrected the default values in the code

I hope this fixes it for you.

Thank you for addressing this so fast.
