Nice.
Do you have a triumph or BSA to go with that Amal? :D

Keep us posted with your thoughts.

Tried a bit more and I some scans are very striped.

Tried different shutterspeeds from 1/60 down to 1/27. No change.

Any Ideas?
These scans are without any changes in the settings at all.
Just pressed the scan button a few times and the scans turns out good sometimes and bad sometimes.

I got similar defects.
Tried once, but got less problems over 160 (ms?)

Make sure you are not shaking the table with the carb on it or the cameras.

@Mading, What setting are you referring to ? The 160ms.

@µ - nothing moves :-)

The number you see when you select "advanced" Above the cameras.
I got no data unless I increase above 160 (or whatever I don't remember).
If you press "Estimate" Gives you the theorethical syncro delay (I guess). Gave me 60: no data, only occasionally. If I increase the parameter data progressively appear.

Thanks Mading!

The text is missing on those figures. Seen them in the manual.
Button "Estimate" gav me different numbers frpm 50 to 170. Can't say I saw any effect.

Made a new calibration panel and was a bit more thorough when calibrating and now it seems to work.

Any one had the energy to look at a DIY rotary table solution?

I'm researching that right now. No clue when I'd have something actually useful to share though...

@Alonso

What is yor aproach to the rotary table?
I see three scenarios:

Use one of the existing plugins and new Arduino code
Make new plugin from example
Make new plugin from example AND new Arduino code
