galvo head - protocol xy2-100

Hello everyone,

I am currently considering building a metal fused bed printer.

I currently have a 500W fiber laser with a wavelength of 1064nm.

I am looking for a galvo head for printing.

I would like a printing range of 300x300, so I am considering a laser beam expander to output 18–22 mm and an SL-1064-300-420 type F-Theta lens.

As far as I understand, the ideal solution for the head would be to find one with an xy2-100 protocol to use xy2mod.
And I am aware that I need to find a computer with very low latency.
I have a Mesa 7i97t, but I assume that it is not compatible because the protocol expects a PWM. What is the best card for galvo heads?

One last thing, is it possible to calibrate the galvo head? If so, how?
 

These guys got it working with mesa and it seems  the pktuart so your 7i97 should do it..

Thanks for the link. I had already looked through the thread and stopped at mesa 7i96.

However, I didn't see anything about optical correction. Is it possible to calibrate the laser with LinuxCNC, or do you have to use the manufacturer's software? 

XY2-100 needs at minimum 3 differential outputs
(X data Y Data and clock) so you would likely need some
kind of daughter-card like a Mesa ENC422 that converts
single ended TTL level signals to differential signals.
in conjunction with the 7I97Ts parallel expansion port

(The converter is really just one chip (26LS31 equivalent on a small PCB)
