Design principles
Modix version 3.0 continue and strengthen the winning design principles:

Components Dream Team- Version 2.0 offered a balance of price and several premium key components, version 3.0 could be now classified as premium in almost every relevant aspect.

Easier and faster assembly – Assembly time was shorten dramatically. Our target is 1 day assembly and it might take more than one production batch iteration to get there but the new version design allows it. It is now symmetrical in all corners, no more left or right side specific parts. Print head assembly is much easier and overall more intuitive.

Modular design – version 3.0 provides wider hotend selection (V6, Volcano & Super volcano), easier to customize enclosure ACP panels that are easy to drill and cut for any integration need.

New look – version 3.0 design was about cleaning the look , more black, more industrial.

Electronics – Version 3.0 is now shipped with Duet3D, a 32bit electronics board with advanced features for the high end 3D printing. With Duet, changing printer configuration does not require firmware recompilation anymore, all you need is to change a configuration file and restart your printer. The duet is preinstalled with the powerful Trinamic motor drivers that can push a much higher current dynamically and on demand to the stepper motors. No more manual current adjustment, the new Trinamic drivers can dynamically increase power as needed. These drivers can also sense pick power demands that might point on stall such as generated by a clog in the hotend. There are many other features that allows better reliability. i.e. when the board senses a temperature error the print job is now paused instead of halted as compared to Marlin behavior before. With Duet also the power failure resume is available making the Duet upgrade an extremely important update. Duet is developed by Duet3D LTD, a respectable commercial company from the UK. They host an active support forum and many advanced user tutorials and guides on many advanced topics and optional customizations such as macros and hardware extensions.

User interface – With Duet there are new and modern types of user interface. First, is the availability of a large touch screen. It allows easier operation with a touch of a finger while a real time printer status data is being displayed. In addition, the selected default Duet is the WIFI version that allows a full web access from any mobile or desktop. There is an Ethernet version in case a customer needs it. Now you can load a file right from your computer and start your print without leaving your chair.

Motion System – Higher grade of motion system including:

Four Z screws – The Big-60 will now offer four Z screws instead of three. With four Z screws, the bed is much more stable during fast movement and accelerations, resulting in a smoother print surface than before. With four screws the tilt bed calibration is better controlled.

Standard Hiwin rails in Z – In addition to 4 Z Screws, we have now added 4 Hiwin motion rails to Z axis and replace the smooth rods. With the rails, the bed is now attached to the printer frame itself allowing higher print stability especially for very tall objects and fast accelerations.

Higher grade of Hiwin motion rails – For all axis, we are now serving a higher grade Hiwin motion rails. With version 3.0 we provide rails from the MGW series instead of MGN. Hiwin MGW motion rails are wider than MGN, the riding blocks are longer thus providing higher level of stability in all directions.

Drag chain assembly – On the Y axis, the drag-chain is now installed in a reversed position allowing the most of the drag chain weight, that carries the IGUIS cables, to rest on the Y axis profile. This reduces the load from the Y axis motor and also reduce the resonance on X axis as the whole structure is much more stable and tightly secured.

Removal of X shaft – We have replaced the long shaft and geared motor with a simplified dual motor configuration. Each motor is now pulling only one belt (one on the front and another on the back). This makes the assembly, maintenance and even the belt tension a much easier task than before.

All wires are now IGUS – Now also the X, Y & Z axis stepper motors wiring enjoy the same extruder IGUS shielded cables. This reduces electromagnetic noises of the motors to affect the rest of the printer.

Print Head – The new print head was redesigned to allow compatibility with the advanced E3D AERO extruders that eliminated the old long heat sink design. This family of extruders arrives with a much larger but shorter heat sink and a 40mm cooling fan instead of 30mm fan as before. This reduces risk for hotend clogs in a closed chamber printing and with higher temperature melting print scenarios. The latest E3D Hermes extruder is now being examined and will be our primary extruder offering once it will be available by E3D.

Dual direct drive – New dual direct drive setup for dual material printing. A direct drive provides more accurate print results for the support material.

Larger selection of hotends – The new print head configuration is now supporting all three E3D hotend configurations, the standard V6, The high flow Volcano and the new super volcano as well. You can simply slide the BL touch probe and hotend cooling fan up or down and set the new hotend configuration with ease.
