Galvo - Galvonometer Discussion
I don't want to make do with a Filament Extrusion machine. I want something a little more accurate and industrial, which means SLA (Stereo Lithography) or SLS (Selective Laser Sintering).
Both of the above ideally require the use of a Galvo system. Two mirrors, each positioned by a motor/driver setup, to direct a laser onto a bed containing a substrate material.
There doesn't seem to be much information on how to control such a system. My main goal at present is to figure out what signal is required by a standard or even a disco lighting galvo, and whether or not I can use what I already know (Stepper signals, and Mach3 etc) to control such a device.
Any thoughts on the above would be greatly appreciated.

Hey, somebody please suggest me a software for SLS 3D printer with galvo scanner.

There is another galvo scanner controller on the market that is custom made for SLS and SLA 3d printers. BeamConstruct. Here is the site "www.lasermarkingsoftware.com". You can fiind there controller's and software perfect for 3d Printer's.

If i understand it the right way.
A 12Bit DAC uses pwm signal like for cnc spindle control.
Then it converts its 0-5v pwm( digital sine wave ) to 0-10v analog ( plain voltage).
So if you have a breakout board that supports a addon card like the cnc4pc C6 spindle control.
you should be able to get one axis working.
Just cant figure out how you would do the second one.
Cause if am right mach 3 or 4 does not support 2 or more spindles or am i completly wrong here ??
