Form3+ Castable Wax 40 cleaning mesh?

My resin is full of particles from a failed print. Tried to use the Cleaning Mesh and got the dreaded “Material is not supported” error. Using Firmware 2.5.1-2345.

Per some older articles I tried powering off and powering on. The first time it gave me an “unknown error” rebooted again and now I still get “Material unsupported”

Can you print a mesh using Castable Wax 40? if not… Why Not?
Are there any alternatives other than filtering the resin the hard way?

Thanks in advance!

I’m sure you’ve already figured out a solution by now but we filter our resin through disposable paint cone filters.
