You should be able to see the metal build plate through the bottom of the petri (by looking into the mirror). Does that help?

Starting to print.]]> I am a new owner of the littleRP a got a lot of problems by calibration the z axis. Do you have a tip how to calibrate the dishes and the object holder. whats the exact space between the dish and the z axis and is there a possibility to save it.

Thanks for our help

Kai

Have you used the 10mm grid projection image to test your projector distance/focus?

Boy I love windows 8. For some reason my laptop loves to change the settings when it restarts and this time it decided to turn off my monitor after 10 minutes of inactivity so I wasted some time this morning. I printed the following test from the LittleRP site. Again, the dimensions are slightly off but the surface finish on it is amazing.

Printing with funtodo resin industrial blend. My initial settings were too high and the resin stuck to and ripped the pdms layer. I changed my settings to the following: 4500 for first 8 layers, 800 for rest of layers with 50 micron z resolution. This seems to be working out fine although I think I may be able to decrease the time a little bit. I printed the calibration from the littlerp website and then printed a dental model. Measuring them they are both slightly oversized. The cylinders should be 2mm (as measured in netfabb) an they are about 2.2-2.3 mm. They are mostly round and straight. The dental model that has the cylinder should be 2.2mm and it is closer to 2.8. Otherwise the prints all look pretty good.

So where do I go from here? I am thinking I need to reduce the exposure time and work on making sure the projector is in perfect focus. I will grab better photos after the weekend, my dslr/macro setup is at my office.

Got my LittleRP yesterday and assembled it during work. Hope to start printing tonight. Build was fairly easy, probably would have taken 2 hours straight but I did it in between patients.
