I can attest to F2’s near-sentient attempts to thwart the wringing of every last drop of resin from a cartridge. But other than a personal sense of thriftiness or other victory, what positives do you get from doing it? Maybe this is a “choose your battle” situation.
F2 tells you when the resin is low before the bad behavior sets in. You KNOW you’ll have to buy more resin sooner or later, so simply why not sooner rather than later? I get if you don’t want to pay the extortionate prices until absolutely necessary, but when is that? After you pull your hair out fighting the uphill battle of forcing the F2 to act clearly contrary to its capitalist programming? And then you STILL have to buy new resin, at the same high price, but now with an extra helping of resentment and lost time/hair added on.
Trust me, just buy the damn resin when you know you’ll need it. That’s the system, they call the shots, you can’t game it, you can’t rig it. Buying Formlabs resin always hurts. Don’t Sisyphus yourself into making it hurt even more. As objectionable a system as it is, we all agreed to it when we clicked “Buy Printer”.
