For the Wanhao duplicator4, you will need to print these files, already oriented as needed. Here are a few recommendations for printing:
This is your last print without Zimpure!
Unscrew the two screws of the plastic part which holds the filament guide and remove it. Place the FlashForge Suction Head at this place as shown on the picture below. Rescrew these two screws.
Insert the hose into Wanhao duplicator4 holder and plug the other side of the hose into Zimpure.
Here you go, your Zimpure is ready to filter! You need to turn it ON only after than your duplicator4 has started to print. Please verify how the beginning of the first layer goes. You are now all set up to print safely, without any toxic emissions. Happy safe printing!
