Streamer

Hello...

I just seeking for possibility to use LinuxCNC to be something like printer.
So basic Gcode just make scan left to right and to advance Y every pass.
Now how to drive head? There are no Gcode to do that as I know.
But there seems to be nice component called STREAMER.
The idea is to make print data to file, and then load that file to streamer.
The problem is that streamer doesn't have right pins to control it properly.

The idea is to sync the step signal from X to be clock for streamer.
So each step pulse the streamer update own pins from file.
And that is perfect to be used as printer.

So what do you thinks.
Is it possible to use streamer in this manner? (It should run in base thread)
And of course they need another pin to act as clock(or just use enable pin),
and add parameter to describe how enable/clock works.
(Rising edge, falling edge, stop, continous)

None seems to be finished.
But I look into code of streamer and I think that syncing the stream with X step is good solution . (well it doesn't work with mesa but just plain stepgen on printer port.

Actually theres some preliminary firmware for "painting" from a FIFO buffer based on encoder counts, this could be ported to stepgens relatively easily (this was done for a Mbit output rate application)
