I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

It does a pretty good job, but I've learned some tricks to help improve the print. For example, I will add supports on surfaces that are parallel to the print bed. The software can also optimize the position of the part so that it has the best print quality with the lest amount of supports. Don C 24-Mar-20 18:54 Do the supports hold it off the sheet, or do o have to cut it out of the sheet? This is really interesting, but I'm one of those "old dogs". I can learn, but not sure if it is worth the investment. edtherenderman 25-Mar-20 09:41 Don, Yes the supports keep it off the sheet. The sheet is really a "pad" that holds everything onto the print bed and is printed along with all the parts. When it is done, it is one big object. There are two reasons for the supports: 1) The resin shrinks slightly as each layer is applied. The supports allow the print to flex as it shrinks, and 2) because this is printed one 50 micron layer at a time, some parts of the print need supports so that they can start off the object and "grow" back to the main object as it is printed layer by layer. The software figures all of this out for you. I use its recommendations, but add my own where I know that I've had failures in the past. It really is a lot of effort, time and money. For me though, it combines four of my favorite hobbies; 3D modeling, 3D printing, balsa models and plastic models. Perfect storm, so I'm very willing to do it. I love being challenged too, and this is a way of keeping excited about all the hobbies. Don C 25-Mar-20 11:11 Thanks for the explanation. It's really a neat thing.
