Hi, I recently started using Polymaker Polycast filament for lost pla casting. The frame is fairly large(9in x 7.75in) and I keep getting 'ErrD' which might be due to the size. On top of that I was wondering what went wrong with this burnout, came out dark/ashy/brittle and I'm wondering what would remedy this, thanks for reading
Update: Figured out the ErrD issue but now there's intense cracking in the investment... Gonna let it sit longer after the mix/pour before going into the kiln. Using r&r ultravest investment with de-ionized water
