If you’re trying to build a fiber laser, at this point in time, I don’t know how reasonable that is.
There is no pwm control to a fiber laser and the galvos seem to have a different interface than stepper motors, labled similar, might be power, they don’t need much.
There are limited controllers out there that Lightburn supports as far a using galvo, but some are appearing using grbl gcode, but I’m not familiar with them or how they’re implemented within Lightburn …
I have a BJJCZ USBLMCV4 EZCad2 board in mine. You can check this link for a couple of the new boards that are supported.
EZCad3 and it’s new board isn’t supported yet, which includes a Z axes control. This is the manufacturer of mine.
I don’t think I’ve seen any of these that are supported for <$400, this is just the controller.
What kind of galvo are you attempting? Welding, 2d/3d?
Laser source?
