    Its a bit slow isnt it? How long to do a 10mm part?

    The speed is adjustable through a few variables. The exposure time (time the slide displays on screen) The dwell or delay between the up & down movement of Z (set at 2 seconds in the video) and the feed rate (which is controlled in Mach or set in the macro)
    Of course the exposure will depend on what works best for the resin used. The feed rate & delay between the Z moves can also shave a few seconds per slice off the time. Either way, this is not a fast process. a 10mm object will take anywhere from ~ 15 to 20 min. This is at .1mm slice thickness & 10sec exposure time.
