Improved Version With Filament Tension Adjustment This new version of the BMG-HT allows for the distance between drive gears to be adjusted. Two screws on the side move the secondary drive gear carriage allowing to adjust the BMG-HT to more filament types and hardness. A Professional Upgrade Kit The BMG-HT is a high temperature resistant, rigid, strong, lightweight, and good-looking extruder. BMG-HT becomes our first Professional upgrade kit that will improve reliability and performance of professional and industrial grade 3D printers. Lower Weight Load For Increased Performance By using our 3:1 gearing ratio, we increased the available push force and resolution although using a pancake high temperature stepper motor. The lightweight stepper motor and the Aluminum housing lead the overall weight of the print-head down. Comparing the parts replaced and added in this setup for the Funmat HT, we lowered the weight load from above 400g to less than 260g. An over 35% weight save that will have meaningful and positive impact on the printer’s performance: Less wear and tear of the linear motion systems; Better surface quality; Ability to 3D print faster. Direct Dual Drive Extrusion Like in all other Bondtech extruders the BMG-HT also uses our award-winning Dual Drive Gear Technology. You will experience effective and consistent extrusion no matter what material you are feeding to your printer. Our Dual Drive system will keep on going to help your Funmat HT laying down perfect layers and make your prints shine with a bright you didn’t think to be possible. Stepper motor must run below 1A. We recommended to set current to 0.7A. Different Funmat-HT versions come from factory with different stepper driver setups. Be sure your machine is running the extruder stepper motor at 0.7A by checking the driver DIP switches configuration. In case you don’t know how to perform this check, please contact our Customer Support. Thank you.
