Hi everyone

So I'm excitedly waiting for my Rostock Max v2 package to be delivered - still in the US according to USPS though

For the past year and a half I've been mad into building and then subsequently crashing quadcopters. To be fair there has been a small amount of flying inbetween the building and crashing too, however often this flying is held up by a lack of parts. All too often these parts are fairly basic but take weeks to arrive from China. Therefore my initial thinking was that I could aim to create some of these more basic parts at home and get myself back up in the air a lot quicker.

However. Once I started reading these forums as well as reddit (r/3Dprinting) I have just got generally excited about (a) building this thing successfully and (b) the challenges that lie ahead when it comes to successful 3d printing.

I can't wait to get myself to a point where I can offer useful feedback and help to newbies like myself in the forums, in the meantime, sorry in advance for my dumb questions

Cheers

Hello Didymus and welcome to the Forum!
First I would like to thank you for purchasing the Rostock Max and I know what it is like waiting for it to arrive!
Please download the assembly manual if you have not done that already and become familiar with the build.
The manual can be found here: https://github.com/seemecnc/RostockMAX
Happy building and happy printing!
If you can send us some pictures of your build and finished printer, that would be awesome!
By the way, there is no such thing as dumb questions.

Thanks for the welcomes

I now have hopefully all the bits and pieces required to build it (sadly had to purchase a set of imperial hex wrenches......imperial! Seriously....get with the now!).

Anyways all of it just sitting here with me on the net hitting F5 on the usps status page every 5 seconds.... so excited!

I've started playing around with Designspark Mechanical to get a feel for how difficult the modelling side is for my first real attempts (after many many cubes and tuning etc).

From a slicing perspective I downloaded KISS slicer which was able to load the stl I produced. Was quite shocked that even for small & basic parts the printing time is quite significant. Taking a design from thingiverse for a hex bit storage thing which looked quite small was up at 4+ hours.... does that sound normal or do I have the slicer misconfgured? I took the kiss configuration from these forums....

Without knowing the specific model and machine configuration, 4 hours could be anything from ridiculously long to hopelessly ambitious.

If you don't have fine details in the model, a large nozzle allows greater extrusion width and quicker printing.

Without fine details or a need for smooth surface finish on the near-vertical surfaces, taller layer heights up to just shy of your nozzle diameter will speed things up dramatically.

For various reasons, X and Y print faster than Z. If you can print an object multiple ways, the way that results in the shortest height will usually be faster.

From there, you're dealing primarily with the volume and complexity of the object and the density and complexity of the infill you're using.

Sometimes it's unintuitive. I had a model that was taking longer to print than I wanted on which I'd made thicker walls than I really needed. Redesign with thinner walls resulted in a lot more retracts and travel moves to do the infill and added about 50% to the print time.

Cool thanks for the info and tips around layer heights/xy>z. The model I was talking about was this one: http://www.thingiverse.com/thing:518107

Does that seem reasonable? Perhaps it is because of all the holes?

It seems a little long but not crazy. All those holes will definitely result in a lot more retractions and travel moves.
