Theoretically the procedure is as follows:
- Set the oven on it's lowest setting to force the moisture out.
- Have something to absorb the moisture. I was going to use rice.
- Prop the door open to allow the moisture to escape... I forgot this step.
- Let it cook for a couple of hours.
Set the oven for "warm" and forget it for several hours.
1.77mm. Mission accomplished. I'm just going to save the rice for next time, but it worked great. Now I can use the last of the white with the black filament I have for dual printing and not worry about diameter differences.
