Oh Moai... #Flex3Drive #2in1Duo you got this. Thats the Cura (3.2.1) profile proper dialled in. I wont be at #MRRF2018 in person, but my DNA will be there in trace amounts on a 2in1Duo near the Atomic booth. Go check it out.

My UM2 (with Flex3Drive) print quality wasnt what it used to be. Got tired of endless investigations and replacement parts (belts, bearings, nozzle, driveshaft etc) to fix it, all made very little difference. Was sure it used to print better. Reference print on the left.

Decided to fit TMC drivers to it as a last resort. Remapped some pins onto external carrier board. Result is on the right. Fixed at last! Given the difference I might have had a board based driver or component issue (but same on both my UM2 machines??), hard to tell, but I can now safely say it has never printed this well. Super smooth !

Now using prerelease Flex3Drive #2in1Duo for production prints. Its the nice little touches. In this instance we are doing a simple colour change on our tensioner arms for these G3 Flex3Drive extruders. No retract, purge or waste block/tower and no priming. Simple straight forward gcode command to switch between one or other filament. Using our gcode post processor we simply instructed it to make two sharp unblended colour changes in the gcode equidistant based on print height.

Interestingly the unit in the centre, is using blue PETg and Black ABS. Not too shabby! What do you 3D folk think?

The new PrintBite+ improved in every way. Thinner but tougher, more adhesion at lower temps, available in clear or black, with matt or gloss finish. supplied with adhesive applied. Possibly the most versatile universal print surface on the market today performng well with basic filaments right through to PC's and Nylons aand other exotics. It took a lot of work getting this new PrintBite+ right.

A couple of simple 2in1Duo test prints with Gcode post processed to assess uniformity of mixing and compatibility of app with gcode from different slicers. So far the app has been tested with S3D and Cura generated GCode.

A couple of images to show size and form factor of the 2in1Duo. It certainly is the smallest lightest 2in1 mixer solution in the market today, and potentially the only solution of its type, with the Extruder and Hotend designed to work together.

The unit is shown here fitted onto a mounting plate for the Tevo BW. The 2in1Duo is planned to be sold as a complete turnkey mixing extruder solution. Fully assembled with wiring harness and hotend installed means it will be one of the easiest installations possible. A range of simple carriages can be printed for various printers. Nozzles are also changeable.

The hotend is mounted directly onto the extruder base, as is the integrated cooling solution. Four M2.5 bolts will mount the whole assembly onto a carriage or gantry quickly and easily.

Filament loading and unlaoding is simple and straight foward, with PTFE guide tubes integrated into the quick release tension arm. Simply flick the lever up to unlock, remove and reload filament without fuss or fidget.

More info coming soon.

Heres a close up of a more intense print created with the 2in1Duo. The print had an error in the slicer settings but its often too late when you realise, and then it is a case of "hmmm should I restart or let it carry on?". In this case the error turned this into a 40 hour print, I would have expected 20 hours max. In any case it turned out rather well for an initial shakedown/torture test print. Sliced with Cura, printed with FormFutura's Black PETg and Blinded Green PETg. Started with Green and and single fade to black gradually over the course of the print. Standard GCode post processed with the Flex3Drive mixing app. I think this has turned out rather respectably with all things considered.

Here's a looksy of what I have been getting up to recently, the Flex3Drive 2in1Duo - a dedicated Extruder/Hotend mixer combo where the two elements have been designed specifically to work together. Its very small and compact.

Have run all sorts of material through it, ABS PLA HIPS PET Flexibles, Nylon etc, and all without issue. Some torture tests have also been done including heat soak and standing hot starts.

Works easily as a "two colour switching extruder" without having to retract filaments, my focus has been on testing the mixing capability along with a couple of other nuggets soon to be revealed. The results are however pleasing.

Takes up less room than most other single filament whilst also mixing nicely, Black and Gold has been coming out a treat as do other metallic or trnaslucent colours:) It is based on Flex3Drive tech gives plenty of power and precision.

Shown is the printed version. There is also an injection moulded design which would make this far cheaper, but cost of tooling is the obvious hurdle. A shave under £20k from a local quality toolmaker its an option worth serious consideration. Only the main housing elements need to be tooled as I already have the geartrain tools and other parts.

Thoughts and comment appreciated. Why have a single filament extruder, when you can have dual filament in less space :)
