I recall seeing this and it immediately occured to me that the manner in which the complaint was being based upon a loose "interpretation" of the relevant claim, and rather lopsided i had een meaning to revist this myself and dig deepr, i have some more info collated on this and will be reading up soon.by Mutley3D - General
Quoteumdpru what kind of cable is used to drive the mechanism? Is it a small flexible shaft like a dremel rotary shaft or a larger diameter hollow shaft? Does the filament go to the hot end through the shaft or separately? Hi Umdpru It is a 3mm diameter 900mm long flexible driveshaft, it is supported within a PTFE tube and conduit assembly, Filament is fed into the top of the extruder body andby Mutley3D - General
QuoteMrDoctorDIV I would love to know as soon as you have a dual extrusion version, the only reason I don't have dual on my Solidoodle is weight and size. MrDoctorDiv I think when it boils down to it that is the same for everyone else, both pure users, and those that consider designing such items. At the end of the day for me, the sooner i get a steady ship by way of sales of the Uno, those peoby Mutley3D - General
Hello, Just a brief update on a couple of items id like to share with you that im quite excited about... 1. The website mutley3d.com is now live with a place to make purchase, there is a bit of a discount offered to first few buys through the site to celebrate the website and a place of purchase 2. Lots of all the background stuff you dont need to know about mostly sorted and back focused to asby Mutley3D - General
This type of thing MUST gain real momentum as just one facet to the KICKBACK that must continue to grow. Competition is fair game, Makerbot have something they can sell and have a very strong backer of course there is no doubt.....HOW....EV....A!

I have the equipment (CNC Beast) to cut wades gears from Aluminium, as a one off i wouldnt expect them to be cheap, as a batch would make more sense for resale, but i cant afford to invest in them for a one off. In all honesty, id probably call them a Wades equivalent as there may (not definately) be some slight change to the teeth profile, id have to investigate some. I would also ask the sameby Mutley3D - General
@ Repper Thanks for the post and pictures and good to hear your happy with it. Greatly looking forward to seeing others printing with Flex3Drive as this was the ultimate goal. It has been a lot of hard work and effort. If you need any features added or modifications (no matter how small or trivial) to the X car i drew up for you just let me know and i can do that too and then sign it off as a reby Mutley3D - General
Quotekarabas What is your retract settings? If f.e. Torsional Deflection = 6(12) degrees per ft per lb and effective diameter of hobbed bolt = 8 mm and stepper max torque = 4.4kg/cm for 900mm shaft and 40:1 reductor we get about max 0.125 - 0.3 mm e-feed error. I wonder if it is acceptable. It seems it's better than bowden. Hi Karabas, Id suggest using 6-12 degrees assesses a worst case scenby Mutley3D - General
Quotekarabas QuoteMutley3D Quotekarabas What is the exact weight? 39.22grammes without hotend Including flexible shaft? Hi Karabas, Perhaps i should have mentioned that the Flexible Drive Shaft effectively floats back and forth with the extruder and X carriage assembly adding very little weight if any (in the order of 10grammes possibly but little more if at all). I do intend to check this vaby Mutley3D - General
Quotesxt173 Thanks. I'll try a new Arduino. I don't have any on hand so I'll see if Radio Shack has any or it'll be a week or so. What is your location? If uk maybe i can help speed you up with a donor borrow?? Duh just realised "Radio Shack" nvm.by Mutley3D - General
Quotesxt173 Yup. I tried reflashing and no go. Is there an easy way to just check to see if the Arduino is still fully functional so that I can at least rule that out? I would suggest trying a different Arduino board flashed with the same firmware if you have one to hand (even if taking off another machine) otherwise buy a new one for spares and test with that. Not the "cheapest" way to eliminby Mutley3D - General

QuoteRalph.Hilton I'm building a second printer changing quite a few things as it slowly progresses. The new E3D v6 inspired me to to consider going for a Bowden extruder. I was wondering about optimum placement of the extruder motor and what people have had best results from. It would seem best to keep the tube as short as possible so was considering a swivel mount attached to the Z assembly thaby Mutley3D - General
Quotekarabas What is the exact weight? Karabas, thank you for your question and a very good point to raise... Mass of the single filament extruder assembly is... 60.61grammes with JHead Mkv-B 39.22grammes without hotend +-5% The dual drive version will be less than 80 grammes (+ hot-end) noting that the internal drivetrain components can be swapped from the single to the dual drive when itby Mutley3D - General
A Patent filed anywhere bound by the PCT (Patent Co-operation Treaty) will have UP-TO but not more than 18 months before it is made public. A patent application can be made to drag out over more than 5 years for a number of reasons, and this control is in the hands of the entity making the application. Publication will occur after a maximum of 18 months however. You can also push a patent throuby Mutley3D - General

QuoteMrDoctorDIV Here's another question: What's the horizontal distance that can be reache? It's a 900mm shaft, but with how things move and collide I can't imagine you'd get a movement range of any more than 5-600mm. Of course, I have no idea how in/flexible it is. Another great question....In the current arrangement 600mm is safely achievable and possibly a bit more. With some clever thoughtby Mutley3D - General
Quotejkoljo Nice and interesting design. What's the second moment of area for the drive shaft? I will endeavour to get this information from the shaft supplier for the second moment of Area. I can confirm the delta between in and out is Zero and why this shaft was chosen. My focus is on implementing and executing what is in the innovative minds eye backed up by nearly two decades of experienceby Mutley3D - General
I have thought about this too and arrived at the fact that you will essentially have an extruder with LM8s fitted to it. The Flex3DriveTM has the hot end sliding in from the front of the housing with a snug firm push fit into the groovemount so this would apply here. As for the bearings, the slide in from the sides, again with a firm push fit, possibly with a locking grub screw or a slight raisby Mutley3D - General
QuoteMrDoctorDIV What's the response like? What's the delay between motor movement and end movement? Flexing compared to bowden? Hi, I believe you are referring to something often described as "backlash". This can be caused in different ways depending on the mechanical element of the machine that has this "lash". Play between gears, toothed belt and pulley mesh, belt tension and so on. In the Fby Mutley3D - General
