I have a RGB laser using DT-40 PRO galvos.
There was some bad noise on the galvo output, after a connection from both X and Y signal into GND it was better.
But I still have some trouble on the scanning, it seems that it worse at one side ?
Any advice how I should approach this problem?
Here is a video:

I would also like some advice on the output settings
Cheers
