Yes! She keeps me honest and has a very effective "Malarky meter".

Short time yesterday, but work continued on the interior side walls. Got the Living Room first floor side completed. And I did put some artwork over the fireplace. Just noticed that the trim is short on that far right window casing. Oh well... I may have to reprint the smaller casing and I can redo that... or not. Since it's so far over it may not be visible.

Got a good start on completing side two (dining and kitchen).

For the second floor windows I may go less elegantly. I'm thinking that those windows should be obscured by drapes and/or shades so very little will be seen. I may put the wall paper directly on the outer surface and not spend the time to pack it all out so the window casing overlap the window frames like I'm doing on the first floor.

Based on a suggestion on the Elegoo Mars Facebook Group I downloaded and tried using the PrusaSlicer, a free product that is more comprehensive than ChiTuBox which is included with the Mars and must be used to feed the Machine. While PrusaSlicer may be more elegant, I was dubious about the support array in the auto setting. It looked insubstantial for such a massive object. BTW: I redrew the kitchen unit to solve some of the problems with the previous print (warpage, detail obliterataion).

The processs to use the PrusaSlicer with the Mars is two-step. First, you import the STL file into PrusaSlicer and let it set up the supports. Second, you export this supported part as another STL file into the ChiTuBox to slice for the Mars. Here's how the imported STL looked sitting on the Mars slicer.

Like I said, this scheme seeme a little light. And it most certainly was. This is what greeted me this morning.

PrusaSlicer Fail

Total BUST! And will require a significant clean up to remove the cured blob that most certainly is stuck to the FEP. That EPAX film is getting a bit tired anyway so it will give me an excuse to replace it. Since I already printed this part successfully using the ChiTuBox support setting, I know the part is printable, so I'm now concerned about PrusaSlicer. Like ChiTuBox, Prusa has a lot of customization (even more) so I could have added more supports. Next time, I'll use my intuition and my 1.5 years of printing experience. If it looks skimpy, it probably is. Considering how long the supports are, the part may have broken free later in the print when more mass was hanging on the supports.
