Just a quick question.
On the lil G beam, should the factory 5mw green laser stay on the entire time -- and the mirrors deflect it, or does the cpu modulate the laser when the mirrors are in position?
From the manual flecom posted I assume it's 8 channels and no extra channel for laser control?

I'm hacking on two units. One has no laser output, and I figured out what was wrong with actuators (ground lead soldered across them all lifted off of one, bad solder job from factory.)
Second unit has slight hint of green laser output but the DMX RX light doesn't come on. I dropped a 2nd level IC on top of the first but still no go, scope is in storage so I can't see if it's being held high/low on output. Will socket it next time I bust out the Hakko.
So curious what the operation is. Going to modify them quite a bit.
Both of mine have scrubbed chips, and one of them has set screws for X axis on turrets and 2nd one doesn't. I like the set screws.

I also got a SC-100 scan controller analog modulation jibbie jank (but no scan head.) Up for trades, especially for 4 single mirror turrets or something.

-----[ potentially useful info for others below]----------
Chips in case someone hits one with scrubbed ICs:
U7 - SN74HCT245N
U2 - SN74HCT773N
U6 - CD4040BE
U5 - 74LS245N
U1 - SN75719 (DMX-512 level converter)
U3 - TEMIC P-098C31-16 (CPU)
Also there is a masked rom for program storage and some IC for laser diode current limiting or whatever.
