    Good to know. What issues did you have with the larger size?

    Hey! Great project! I was planning on building something like this next spring, and this would work perfectly. The difference with my build would be the size. I want to print custom clothing patterns, so I want to have a ~1m * ~2m draw area. How difficult would it be to change the STL's to spread the bars out to minimize racking? Could it be done in Thingiverse's Customizer?

    Nice build! What just struck me is how easily versatile it would be if it used a 'pulley stack' -like drill presses have- in each arm. That way, you could have shots that focus on one close point to 360 degree panoramic shots, just by adjusting a belt or two.

    Love it! Here are a few ideas that popped in my head while reading (YMMV):1. If you pour the resin into a spinning 'mold', it will form layers on the sides of it. The RPM will change the angle of each layer, from a slight depression in the middle at low speeds to completely parallel to the axis of rotation at high speeds. (I'm not sure if slower RPM's will cause the layers to be thicker on the bottom or not.) The highest RPM's should cause bubbles to evacuate completely, as the resin will be pushed outwards with a lot more force than gravity. Obviously, removing debris while it is still liquid will no longer be possible.2. Rapping the piece on a table should cause at least some of the bubbles to detach and escape.3.

Obviously, removing debris while it is still liquid will no longer be possible.2. Rapping the piece on a table should cause at least some of the bubbles to detach and escape.3. If you DIY a vacuum chamber and set the piece in it as soon as you level the resin, the air bubbles will all evacuate quickly and easily. It doesn't have to be anything fancy; a tube with a rubber piston that has a foot loop attached to it should create enough suction when you step on it.4. I don't think that you would be restricted to flat layers. For example, if you make your first layer contain the sky, your second, third, and fourth layers could be tilted left/right/up, and be angled buildings for the first two and the street for the third, leaving the center clear all the way back to the first layer for more flat/angled layers.Hope this helps!Keith
