Hey all. So yesterday was my first handful of prints. Id say im off to a decent start, though I’ve already made a few mistakes, and im hoping not to make another major blunder when cleaning my vat. First i accidentally printed the 4 moai instead of the 4 clyinder test, and wondered why it was taking so long. Then, when reading the leveling guide, i failed to realize the build layout in cura is flipped to how I look at it when it comes out of the machine, so all my #s i wrote down were backwards, and my adjustments were all wrong. Finally, since my adjustments WERE wrong, i eventally had C and D failing to print and didnt remember to try and clean them off the bottom of the vat before printing again. SO i had 2 failed prints go thru C and D and stick to the bottom.
So, now i have quite a stuck-on blob on the bottom of the vat. Finger pressure (with nitrile glove) wasnt enough to unstick it, and since i WAS aware of how delicate i keep reading the PDMS layer is, i just put the vat in a zipbag, with the resin, and left it overnight.
I did a bit more reading last night and this morning, so this is my plan based on what I’ve read…
-use a squeege to get most of the resin out.
-Filter it with something to get out any small bits.
-Use a paper business card or a “plastic razor” to gently try and remove the resin blob at the bottom of the vat.
-Clean the vat with denatured ethanol (is this stuff ok? it was all i could find as far as ethanol goes), and some baby wipes. Im thinking baby wipes because they have a much softer texture than paper towel. I was unable to find any large containers of IPA. All i have is the bottom of the bottle in my medicine cabinet we use for cuts and scrapes… and its only 70%.
-air dry, refill, adjust my backwards tightening from earlier, and reprint
any potential bad ideas there that i should avoid?
