Hello everyone

I have 30Kpps Galvo Scanning motors and drivers like the photos I need to drive it with arduino but I don't know how can I do it ? If someone help me I will be happy.

Thanks a lot
Best Regards

Ie this [www.aliexpress.com]

There are some pinouts on that page

control is analog -v and +v voltages... arduino is only 0-5v, you will need some sort of interface to change voltages or accept much less deflection. and probably a higher resolution DAC

see [www.instructables.com] for some more info...

and a bunch of stuff here [reprap.org]

Thanks a lot for replying. I will try to DAC circuit with MCP4725 and tl082 opamp then drive with arduino. I hope I can do this.
