Re: OctoPrint on MK3?

Sun Nov 12, 2017 3:48 pm

I am going for the “official” Pi camera

https://thepihut.com/products/raspberry ... o_s=gplauk

But i have seen a Rev1.3 on eBay which looks very similar but does not have a Sony sensor, so i dont know how it will perform.

I do think its a shame that these cameras use a flat ribbon cable and no-one has come up with a round version to make routing it a littler easier and neater.

Simple question...

What size and speed SD card will be "optimal" for a octoprint implementation?

How fast does a micro SD card need to be? The RepRap Wiki seems to indicate:
>SD-Card (it should be fast, so go for a Class 10)

Will a older slower card be appreciably slower, enough for this application "in use" (not just setup) to be worth locating a fast card for?

Currently, based on a tutorials recommendation for a 8GB card, I have a 8GB SDHC class 6 card slated for installation. Too old and slow for the task?

Strangely I only have the correct amount needed for all my various devices requiring them, and simply purchase a new large one when needed, shifting all smaller cards down the chain like a hermit crab exchange https://youtu.be/f1dnocPQXDQ?t=76

I saw on a tutorial video that a minimum of 16gb was recommended. You can pick up a good 32gb class 10 card for less than $12 USD, assuming you live in the states. Why not pick up a better card if you're dropping $$ on a good printer?

FYI, if you use the pi zero, get the adapter cable for it... I just found out the hard way.

Can yo expand on that? What adapter cable? Is this for the camera? Or do you mean the one for the Mini to full sized USB?

Edit.. I worked it out:

https://www.raspberrypi.org/blog/zero-g ... connector/

So clearly there is an adaptor to convert to the original "course" cable, to the fine pitched one used on the Zero. Thanks for the tipoff.

Here is what we need

But 30 cm might not be long enough, and I haven't found a long cable for it. Maybe if you mount it on the left side, but the bed is 21 cm + length to camera and to board... I have to do more research. I may be repurposing another pi3 for this in the meantime.

This should help, use the small cable and this adapter/joiner to allow you to use the longer cables. At least that's my plan...

There are also hdmi adapters. So one can use round hdmi cables.

Hi There,

My first 3d Printer and I choose the MK3. I am waiting for it to arrive and plan on installing the octoprint Zero W board. I would like to add the camera as well so I was looking for extended flex cables to work. I found these ....

https://www.amazon.com/Makerfocus-Raspb ... TTZ7M&th=1

These should be long enough to place the camera in a good spot. Maybe someone will make a shielded round cable version as well. To long of cable and you may induce noise into the video.

I assume that you can use the 8Mb pixel camera on this Zero W, MK3 system?

Looking forward to the MK3 printing experience!

Cheers,
Rob
