  • Be aware of your electronics. Please don't work on your printer while it's turned on. We advise disconnecting from the mains during installation and maintenance.
  • During use and cooldown, there is a potential to burn your hands.
  • Please read and make sure you understand the firmware requirements before attempting to print.
  • Please check that the components' voltage matches your printer's voltage. Double-check the polarity of connections where appropriate.
  • Your HotEnd and printer are your responsibility. We cannot be held responsible for damages caused by our products use, misuse or abuse.
  • The Revo High Temperature Hotside must be kept clean to reduce off-gassing. It's advised that gloves are worn when handling.
  • The Revo High Temperature Hotside is intended for polymers with high processing temperatures. Low-temperature polymers such as PLA or ABS can cause fumes if processed incorrectly.
  • Similar filaments may differ in specific polymer compositions. Always refer to the filament manufacturers' material datasheets for printing guidelines.
  • Do not overvolt the fan or heater cartridge.
  • E3D parts are intended for indoor use only, we cannot be responsible for issues caused through the operation of our products outside.
