This might be a long shot, but can anyone help me get my galvo working? I’m testing it using a single point in lasershowgen for a stable XY voltage, which I measure the +X-X at -3.5v out of the Helios DB25 - the Helios output light does show when running so I know the dac is doing its thing. This tracks over to the CN8 pins on the driver, but the heads don’t respond at all. I’ve tried python too but no luck. The kit I bought is a PT30Kpps. Thanks in advance.

I’m working on a bench prototype, but I don’t have thousands laying around to throw at Thorlabs or the like - so I bought an A1 Mini and started designing my own system.

I started with a high density modular breadboard using my own design of diamond interlock connector (for tight hold but easy wiggle release) and m6 untapped interweaved for mount stability. 4 of them covers 320mm2, not bad for around $10 and a few hours of my time! And I can just print another and a few more fasteners if I need more room.

I’m working on simple lens mounts now, quite happy with how it’s going. I am thinking of developing this into a full ‘OpticsKit’ project with parametric control, kinematic mounts etc too. Would there be interest in that?
