First the machine is not going to explode if FL gives the user more control. All we are talking about is spilling resin and FL could do better to mitigate problems should spills occur.
I can speak with firsthand knowledge of this having had two minor and one major spill.
First spill was all me as I was experimenting, as any curious person would. Cleaned it up and moved on.
Second was using bone stock, castable v01. and on my machine it will always spray over the lip of the tray when filling. This particular issue could be prevented with some minor design tweaks to the bite valve. Cleaned it up and moved on.
Third was by far the worst and also how I learned the most about the Form2.
Running bone stock again, Grey v02, started the job, walked away and when I returned to check up on the machine I found the bite valve swimming in the resin tray. The better part of a liter of resin had been released and overfilled the tray flooding the inside of the machine. The immediate problem was the leveling sensor was no longer reading correctly causing the job to pause.
After making sure FL was ok if I open the machine, I found, with no great surprise, resin covering the mainboard.
The other part that I found that was surprising was the previous two spills had also made it to the main board just not as significant of an amount.
Long story short after complete disassembly and a gallon of IPA it works again.
He is what I learned.
Spill containment protects the optics pretty well but nothing else, there is room for improvement.
Mainboard and microprocessor board are directly under the path spills will likely flow.
Conformal (may only be a solder mask) coating apparently does not protect liquid seeping under BGA chips. It took a lot of IPA and compressed air to remove the resin from these chips.
The electrical connections, are unprotected and also likely to be exposed to spills.
What really raised my eyebrow was the open frame power supply sitting under the front spill containment catch area with no shield to deflect spills if any occurred.
What would make the system even better.
Short of relocating electronics above the water line so to speak, Potting the PCBs or at the very least a conformal coating that prevents liquid ingress for all components.
Sealed power supply or at least guards to better prevent possible spilled liquid incursion.
Under the fill valve is a catch basin, routing liquid that falls into this basin outside the machine may have helped in my situation.
These improvements would go a long way to mitigating issues that could occur when giving the user control over their machine.
Edit: corrected typo. Level should have been leveling
