I guess it depends on the needed video bandwidth
(which would be limited by the servo thread rate currently)

There is firmware for high frequency motion synchronized modulation
but no driver /hal support yet

Hello.
I have a galvo scanner without documentation.
How can verify if it is xy2-100.
Also how can identify what is each wire from 7 wires has for each axis?

I would expect a XY100 interface to have 8 or 9 wires total for both X and Y

X Data +
X Data -
Y Data +
Y Data -
Clock +
Clock -
Sync+
Sync -
Status

The 7 pin connections look more like an analog interface, maybe
directly to the coils

Scanner has manufacturing year 2016 (analog scanners usually are before 2004)
The galvo driver pcb it is the same as this
www.ebay.com/itm/264285622376
seems to be made by novantaphotonics/cambridge technology (product code 1‐002‐3006170 )
novantaphotonics.com/wp-content/uploads/...tus-February-2022.pd

Label outside of scanner writes voltage +-15V.

The interface has 7 wires for X and 7 For Y (7 wires for each axis)
So can this be?
X Data + / X Data - / Clock + / Clock - / Sync+ /Sync - / Status
and
Y Data + / Y Data - / Clock + / Clock - / Sync+ / Sync - / Status

or

(without differential signals)
-15V / GND / +15V / X Data / Clock / Sync / Status
and
-15V / GND / +15V / Y Data / Clock / Sync / Status

I don't think so, XY2-100 combines X and Y so that is not a match

The +-15V suggests an analog interface

I have send email to novantaphotonics for manual they answered me with the manual of galvo scanner.
It is analog..
Can use this galvo interface with linuxcnc ?
Which mesa card is suitable ?
