Just realized something. The otherwise very comprehensive manual for the Form 4 does not have a map of the UI commands. It’s very possible my ADD scan of the manual didn’t see it. In particular, I’m looking for the setting that enables preheat. This is the setting that maintains the resin at a certain temperature at all times. Very handy when working with thicker resins that may throw a ‘debris detected’ error when starting a print.
Let me know if I’m missing where this is documented.

Hey @SteamFactoryLLC!
I will pass this onto the documentation team. In the meantime, the preheat function can be found in Settings\>Configuration\>Resin Preheating. This won’t keep the resin at a certain temperature **at all times** , but it will predictively begin to heat your resin when all pre-print checks are completed (Resin Cartridge, Tank, Build Platform), or if you begin to prep a print on PreForm.
Additionally, (I also mentioned this in [another thread](https://forum.formlabs.com/t/how-hard-or-easy-is-it-to-print-with-tough-1500-v2/44604/29), but just for posterity) the most recent release of [PreForm 3.48](https://support.formlabs.com/s/article/PreForm-Release-Notes?language=en_US) includes a new field in Print Settings Editor, which slowing it down should help with this error if you’re getting it repeatedly for a specific resin.
**Preprint mixer speed setting in Print Settings Editor:** Control the speed at which the mixer moves before a print.
We’ve also adjusted some settings for some of our more viscous resins that were more prone to falsely triggering resistance as debris, so if you’re still encountering this issue please let me know and I will take a look and see what we can do to improve further. (It would be the fastest and most helpful to submit a bug ticket in PreForm’s feedback box and upload your printer’s logs so we can see what’s causing it.)

Fantastic!
