Rostock Max FlexiDrive Extruder [worklog]

Post by brent » Mon Apr 21, 2014 8:36 pm

*thread updating as I progress*

Bought one of the beta units from a #reprap irc user named Mutley today. I like this design and I'm planning on testing it with the rostock max.

hmmm... not sure that will work for the rostock max... are you planning on buying 3 of these to mount to your 3 aluminum extrusions..... I dont see a benefit of having that on there... rostock max already has a bowden extruder.. the drive mechanism is similiar to what the rostock has already for axis movement. Am I missing something here.?

The extruder is on the hot end, while the stepper remains on the machine - it uses a flexible cable to power the extruder - kind of like a flexible extension for a rotary tool works.

Ic... I was seeing the different x axis setup on his mendelmax and thinking that was the flexidrive the op was referring too... that makes sense now..

Now that's an interesting idea... Direct drive without(?) hysteresis?
I loved my Rostock so much I now sell them in Oz :)

Yes. According to the designer, there's no hysteresis in the system.

He removed the Video from YouTube for some reason. It is an interesting idea.

off-topic but I built an enclosure for my romax with the misumi free150 promo today. I'm holding off on completing the max until the v2 upgrade comes out as I feel I'd benefit from it.

That looks like the beginnings of a great enclosure. I wonder if the local home depot or lowes has clear panels that large?
I bought a bunch of the extrusions also during the free150 sale so I am going to watch your enclosure closely because it
looks like a nice way to use some of the extrusions.

I'm hoping that either Grainger or home depot has large clear panels. Otherwise, I'm going to have to improvise with a black garbage bag or a lot of clear bag wrap.

Your answer made me think. I would prefer the expensive clear panels but as an alternative that plastic they sell for windows that you heat shrink in place would work but
I question its durability.

As long as I can vent it and heat it...
