Versatile Solution
4 different units available. Standard (right handed) and Mirrored (left handed) orientation, for both 3.00/2.85 and 1.75 mm filament diameters.
Build Quality
The housing parts are professionally SLS printed in nylon for maximum strength and precision. Included 700 mm cable with quick-connectors, as default equipped with a JST-PH6 to PC2510 connector, an XH4 or Dupont connector is also available.
The Bondtech QR-M utilizes an Nema17 stepper motor with in integrated planetary gear reducer with 5:1 ratio together with precision cnc-machined 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.
Bondtech Dual-Drive
Our unique Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions. Bondtech users the world over will attest that even in prints with thousands of retracts our extruders perform flawless, with unmatched precision, and zero damage or degradation to the filament.
Multi-material capability
The QR-Mextruder 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 or 2.85/3.00 mm filaments, but has been tested to ensure performance of filament with a wide spread diameter 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.
Feeding direction
The QR-M feeds material with equal force in both directions so it is flexible when it comes to integrate it in your application.
Each unit comes assembled, tested and verified for optimal performance.

About the E-steps
Important notice regarding e-steps
The value for the e-steps we present in the description tab is the most common scenario:
1.8°/step motors and 16 bit micro-stepping.
The e-steps depend on:
- the stepper motor angle per step. The most common is 1.8°. Some printers use other kinds;
- 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. 32bit, double also the e-steps value.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.
