Printing wood, metal, soft filaments

Has anyone successfully printed with wood or metal filaments on their Max v2? I have tried the wood several times, but it ended up jamming and it broke in the extruder. The new e3D Titan extruder is out and looks like it may be at least a better solution, so I am looking at that, but if possible I would prefer to not spend extra to get this to work. Maybe my settings are just not good. Any suggested settings from someone where it worked?

Ive done it with a redesign of the EZstruder mounted on my printers arms, but an airstruder with the EZstruder should help you. The main problem is the hysterisis that comes up (flex in tube and filamemt) because its so long. A geared extruder would do a lot but shorter tubes go a long way

That Air Struder looks super interesting. I am quite tempted to give it a go, and maybe then upgrade to the Titan. All the videos I see of it are the Max v1 though. How would I go about attaching those bungee cords? It looks like they are attached to the skates but the injection molded skates of the v2 would be harder.

Thats the trick isn't it. I'm not sure, I don't have the new carriages, the older ones are much easier to worry about. Perhaps you could design a bracket that clamps onto the existing arm mount with a hole to attach a strap to? Thats sort of what the fly-n-strude from trick laser does.

Any thoughts on the Bondtech QR? Might it be better? Ideally a plug n play solution like that would be ideal, but I can see it still being a problem as that doesn't change the length of the tube.

You're also fighting loosing torque, and the stock EZstruder doesn't have much torque to give in the first place. The QR should help, also the fittings are a lot better (thats where most of the tube flex comes from on a stock MAX). Its a lot more $$$ though, might be cheaper to try the airstruder first, and if that doesn't eliminate all problems the QR should.

I took a closer look at the carriage and I think it would work. I wasn't home before to actually see it. I think the bungee cord could easily be attached to the white arm that is screwed on the new carriage. [img]
http://www.tricklaser.com/images/Thumbs ... MAX-02.jpg[/img] It looks like it should be able to wrap around it without interfering with the belt and should be in there pretty solid with the screws. I will try this first as yes it is much cheaper! Thanks for your help, I'll report back with results later on. I am still interested in that Titan extruder so may do that anyway, it is much cheaper and seems like it will help in the same way as the Bondtech.
