I just came off a bunch of travel and just too much going on where I neglected the printer somewhat. I've been trying to setup a better area/desk to work with the printer and needed to dedicate a computer to it in the process.
So, I literally finished a print, took the build table off and soaked in IPA, left the remaining resin in the VAT in the machine, covered the machine with a dark towel/cover, and walked away from it. For about 5 weeks! I came back to it this weekend having fixed up the computer to run it and setup a bigger work area. I looked and the resin had the pigment settled out pretty good, but no curing or anything weird looking so I proceeded to simply stir it back up (in the vat, carefully with the sweeper), top it off, and print.
I rebuild an older laptop with a fresh new Windows 7 install for the printer and installed all the needed software. I didn't even re-calibrate the z! I printed 2 items that came out well (enough) and used it as a data point. I don't plan on neglecting the machine on a regular basis, but was very impressed with the results having just let it sit....
Now that I have a better area setup, I'm planning on doing some 1:1 Cherry/Red Mix and see how that goes with everyone's input from the board (which i still need to catch up on a lot...).
Just thought I'd share!
