Another rostock max build

Very well done and I am jealous.
Now we need to see what kind of prints you can do with that miracle of technology.
It looks like you have 4 points of attachment on the Mic6 heat bed, is it adjustable, like on springs?
That's one big chunk of metal!
Please let us know how she prints with some pictures. Great job!

sorry i missed this question.
it takes quite a bit of time to heat that massive piece of metal, took me 10-15min with the onyx to get to 95c even with my upgrades, but holds temperature quite well; too well, takes a long time to cool down also..
I just have it sitting on top of the onyx not bolted down at the moment. I'm going do some more tinkering to see what i can do to cut that time down.

Cambo,
Have you had a chance to run the magnetic arms and compare with the trick laser arms? They both seem like pretty good solutions.

I have xnarons mag arm mod sitting on the shelf at the moment. I don't know if I'll ever try it out. Rostock is printing pretty good at the moment with my trick laser arms for now.
My magnetic arm mod I was working on was put on hold and I don't know if I'll continue working on it.

Holy crap dude, you're a badass. I'll probably end up with a rig like yours here soon.

Bump for update!

I haven't been using my rostock much lately. New job takes up most of my time..... traveling.
Although I've been looking off and on for a replacement geared stepper motor for the extruder. Just did a quick search on ebay and found this.

I could probably make an adapter plate so the the ezstruder mechanicals will fit onto it. ahh more projects...no time..

You might find that stepper doesn't work well with the pololu drivers at 12V, the "important" spec is 4.5mH inductance, that's pretty high, and you may not get anywhere near the rated torque.

Thanks....hmmm. know of another geared extruder that might work??

sorry for the confusion. That's not what im looking for.. i'm looking for an geared stepper motor only.. not an extruder. Meant to say geared stepper motor.

geared stepper motor which is what i was looking for. bonus also comes with all metal bowden setup. (im a sucker for cnc machined parts. Just take my money.. )

gonna give this a shot and see how it works out.

Expensive but it should last a lifetime with that all metal extruder. The first all metal extruder I've seen.
Let us know how it works out for you.

Finally got around to picking up my new extruder from the post office.
Looks a lot bigger in the photos than in person. It uses a nema 11 kysan stepper motor with a planetary gearbox. Quality and machine work look excellent.. although I'm not sure I like the design of set screws as an adjustment point for roller the bearing. May replace those with something else.. will see.....

I'll post my thoughts once its all setup..
