Yikes is an understatement! The electronic boards where drenched in resin!
I opened up the case to get it cleaned out the best I could. I didn’t realize there was a substantial pool of resin inside the printer. When I was figuring out to get the case off, I laid it on its side - which caused the pool of resin to cover pretty most all the electronic boards!
I spent hours cleaning them the best I could with rubbing alcohol, let it dry overnight, and now I am back printing. If I had shipped it for repair with the pool of resin in there - it almost certainly would have ruined the entire machine.
To the best of my ability the cartridge was fully inserted. Peering through the bite valve hole, you will notice that below the hole, roughly half the of the area is the vat spout, and nearly half the area is the printer case. IMHO this area desperately needs a fluid catching basin. I don’t think I am going to use another cartridge until I modify the machine and install one myself; I came way to close to ruining the printer.
Short of a catch basin - there should be a prominent warning that improper insertion of the cartridge can cause catastrophic results. I had no idea it was so dangerous!
Engineering wise, another nice inexpensive thing to add, would be a plastic umbrella over the electronics sloping away from them.
