Oh hey- I had to find that serial number on the source, so I had to open it up.
Turns out you first remove the 3 bolts on top-front and 3 on top-rear and remove the top panel with the 2 small handles (not the 2 handles on the front panel that the MOPA source itself is lifted by). This allows the side panels to be slid upwards. It is not necessary to remove them entirely.
Meanwell 1500W 48V on top, 100-240VAC. There’s a couple of smaller supplies underneath. It might be able to plug into 240VAC without even flipping an internal switch but that depends on the other supplies. Meanwell 1500 auto-switches.
I do see the source has the DB9 port right there with nothing plugged into it. This is how you’d enable “Performance Mode” which enables 20% more power output, but within a slightly more limited room temperature range. I could do a DB9 extender on a flat ribbon cable, but I don’t see a convenient place to pass that through without cutting a new hole in the case somewhere.
Here’s the neat find, though! Despite the limited OEM cable length used between the source and galvo, there’s about 10 FEET of additional fiber cable stored inside here. This would really help me. The source is currently on the benchtop beside the fixture table and galvo and it’s keeping me from working on long stock. I was going to put it on the floor but saw the cable wouldn’t quite reach from the source to the galvo on my benchtop, and still be able to maintain the necessary large radius in the two 90 deg turns in that path.
The black cable you see from the outside is the fiber cable PLUS the galvo control copper cable. Galvo control is diff pairs for CLOCK, SYNC, CH1, and CH2, an X+ and Xgnd and Y+ and Ygnd, and power gnd with +/- 15VDC. Extending this is a little risky for creating signal probs for the high speed galvo but it should work.
Heck, that weird ideal I had about if it could be a different sort of cutter by running a circular “wobble” directly under the lens so occlusion isn’t a factor and moving the work on an XY table… the mobile XY table wouldn’t be necessary, there’s enough cable here to mount the galvo head on a modestly sized gantry machine. That was just the mind free-thinking stuff out- this does cut differently than a standard laser cutter as it seeks to ablate a track from the top by explosive impact off high energy pulses without melting while the traditional one cuts by melting a channel through and blasts molten melt clean through with an air jet. It avoids heat damage but would be slow and difficult to set up for a clean cut, and would seem to need notably different CAD/CAM and control hardware. Not sure what applications that might actually be useful for.
