The idea of using Gcode to drive the galvos was due to the fact it could provide better setup possibilities for this application; things like G50 (scale factor), G68/G69 (rotate coordinate system) and some other. Another great aspect of using Gcode is that many other path strategies could be...

Thank you. I'm junmping in this "adventure" for sure. Well, the base spot size would be something very tiny, like 0.25mm diameter, so, some variation is acceptable. If this variation gets to unacceptable levels, I could make use of f-theta lens in order to make the spot size constant. Good DLP...

There are several dlp printer projects on the web, but I have my doubts about the dimensional accuracy (not resolution) of it. There are optical distortions related to that.* Laser systems are being used since the 80's for this application, but the machines were very expensive, until...

Thanks for the response. I think that's not a problem, since what matters is that the laser cures the resin. So, no problem at all if the image blinks a little bit. It can even be displayed in a "scan line" fashion, like up/down projection. Can you tell me if it's possible to control the...
