To use this Bondtech Extruder, you will also need to buy the following:
- a Mosquito Hotend or a Mosquito Magnum Hotend for higher material flow;
- the Boron Nitride Paste;
- the Mosquito Thermistor;
- the Mosquito 12V 50W Heater Cartridge or the Mosquito 24v 50w Heater Cartridge;
Optional items
- one or more Vanadium Nozzles;
- a Mosquito 12V fan or a Mosquito 24V fan to cool down the hotend;
- a 1.5Nm Torque Wrench to properly tighten the nozzle(s).
- standard CNC-machined 3mm aluminum mounts
Designed for Mosquito
This extruder is optimized for the Mosquito or Mosquito Magnum hotends (both not included) with and integrated torque lock system to make the interface very strong and makes nozzle changes a breeze. Mounting your hotend is simple, secure, and wobble free by means of just two bolts.
Build Quality
The housing parts are professionally SLS printed in nylon (PA12) for maximum strength and precision.
Nickel Coated Hardened Steel Drive Gears
The Bondtech BMG-M utilizes an internal gearing ratio of 3:1 together with precision cnc-machined Nickel Coated Hardened Steel drive gears to give you a compact powerhouse for all your applications. Whether you require high resolution prints with small nozzles or high-flow prints with big nozzles the optimized gearing ratio combined with our industry leading drive gears provides unparalleled pushing power and lightning fast retractions in a lightweight and compact package.
Multi-material capability
The BMG extruder feeds all material with high reliability, from slippery nylons and soft TPU/TPE filaments to highly rigid and sometimes brittle carbon-filled high-strength materials. The extruder is designed for 1.75 mm filaments, but has been tested to ensure performance of filament from 1.5mm up to 2.0mm allowing for high reliability regardless of the tolerance of the filament used. The filament path is fully guided throughout the extruder body and the housing maintains tight tolerances to the drive gears mitigating the chances of Filament Misfeed when the hotend experiences increased back pressure or highly flexible filaments are used.
Adjustable tension
The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament. This gives you the power to adjust according to your preferences and to optimize for the type of material you are using.
Quick-Release
To be able to do material changes in a snap, simply activate the Quick-Release lever to release the tension and pull the material to be changed out of the extruder, keep it activated and insert the new material.
Flexible mounting options
Standard mounting bracket: standard CNC-machined 3mm aluminum mounts or 3D printable mounts that you can download as CAD- or stl-file that gives you the dimensions you need in order to design your custom mounting bracket.
NOTICE: The extruder is delivered without mounts. If you need the aluminum mounts please remember to add them to your order. Or download a CAD- or stl-file and process/print one yourself.

About the E-Steps
The e-steps depend on:
- the stepper motor angle per step. The most common is 1.8°. Some printers use other kinds
>> And an inverse proportional relationship with angle per step: If the stepper motor angle per step is half, eg. 0.9, double the e-steps value.
- the mainboard micro-stepping setting. The most common is 16 bit. Some boards may use other bit settings.
>> There is a directly proportional relationship with micro-stepping bits: If the micro-stepping is double, eg. 32 bit, double also the e-steps value.
The value for the e-steps we present is the most common scenario: 1.8°/step motors and 16 bit micro-stepping.
