I reached out to Formlabs to ask for a sample of official resin in order to see if our issues were resin-specific or mechanical. They responded with very relevant information (and a coupon offering)
Thanks for reaching out! I’ll be happy to help as best I can.
OpenFL is actually a Form 1±exclusive tool. The Form 1 does not have the laser power required to use OpenFL. Resin manufacturers will sometimes have a “recommended setting” for printing with their resin that is already hardcoded into PreForm— you may want to ask the manufacturer of this resin for such a setting.
This is a bit of a tight spot to be in—we haven’t supported the Form 1 for many years now (since the introduction of the Form 1+,) nor do we sell resin compatible with this printer any longer. The last resin we sold compatible with the Form 1 was Clear v2. This resin is nearly identical to Clear v4, but I can not guarantee that v4 will perform as-expected.
Because you’re in a tight spot, I’d be happy to do what I can—I’d be happy to provide a coupon for half-off a cartridge of Clear v4. Let me know if this would help, or if you have any questions!

So on the bright side, that explains some of the mysteries we were trying to solve (why OpenFL was having issues, and possibly why our prints are failing if the resin isn’t preset-compatible). On the other hand, it sounds like getting it working will be pricey and potentially not even work if there is no compatible resin out there that will work with our hardcoded settings. From here, I think it’d be worth making use of the half-off coupon and giving it a go with their clear resin or trying to find a resin that we know works with the Form1 presets.
