Dremel 3d45

[garyriet]

Question, will the plugin work withe 3D45? Just picked up a brand new one for 500.

[Mrnt]

That seems like a good deal!

The plugin does not have the USB product ID for the 3D45 right now, although it does have the one for the 3D20. You can either edit the code in init.py so that

0x8889: "Dremel IdeaBuilder 3D20"

becomes

0x8889: "Dremel IdeaBuilder 3D20", 0x<newproductIDhere>: "Dremel IdeaBuilder 3D45"

or upload the ID and I can add it.

If you feel comfortable adding the code, it would be helpful because you could go ahead and test with it and see what works.

[garyriet]

I dotn feel comfortable changing code. Lmao. I’ll look into
Thanks

Sweet it works!
"Dremel": {0x8889: "Dremel IdeaBuilder 3D20", 0x888d: "Dremel IdeaBuilder 3D45"},

[garyriet]

I still have to set the other settings for OctoPrint

[Mrnt]

Nice! It’s a pretty chatty little thing isn’t it (looking at the response to M119)

[eduncan911]

There is a PR already open for this issue: #9

Just needs some final testing. I am going to try this over the next few days/week, as I finish testing the 3D20 changes of late.

[eduncan911]

So about that Camera in the 3D45... It appears to be a an M-JPEG stream. I found this URL when directly accessing the printer:

http://[ip-of-printer]:10123

It immediately brings up a default web server landing page of "M-JPEG streamer":

^- Notice a small screenshot of the camera at the bottom of that image? Hehehe...

Why they want the extra overhead of running an embedded Java, and encoding individual JPEG images, is insane. First thing that pops into my head is, "how unsecure is this free-standing java web server on a printer with no security?" Good thing I run these printers on a dedicated Untrusted VLAN for IoT crap. I would never let this thing on my regular wireless.

Clicking on the Stream, clearly shows a simple <img src="/?action=stream" /> HTML code that one could embed to show the camera.

And it streams the JPEG images, with just that img!

As a matter of fact, hitting the url directly brings up a browser-window of what i think is around 800x640 resolution video of the camera feed: http://[ip-of-printer]:10123/?action=stream. Note no "HTTPS", just plaintext HTTP - and no security.

That URL is also compatible with VideoLAN video streaming:

There's also snapshots built in! So you can easily use it for time lapse prints:

http://[ip-of-printer]:10123/?action=snapshot

The final interesting fact is, we have camera controls!

---

So about OctoPrint and cameras... It got me thinking, can it stream the streaming URL?

YES IT CAN!!!

So in summary, when we get the 3D45 working with this plugin, we can clearly document how one would add the Camera to their octoprint instance by saying something like:

To display the camera, go into OctoPrint's settings for Webcam & Timelaspe, and enter the URL: http://[ip-of-printer]:10123/?action=stream

Nice!

[Mrnt]

@eduncan911 Nice job on the camera!

This made me chuckle:

Good thing I run these printers on a dedicated Untrusted VLAN for IoT crap. I would never let this thing on my regular wireless.

Yep, me too, along with the wifi security cams of questionable security...

I have a Dremel 3D45 if you need to test/troubleshoot.

udev rule needed and was added; connection sucessful.

[eduncan911]

@Ve2mrx Take a look at this PR: #9 (comment)

That's basically where we stand. The plugin needs to be tested.

Note, right now there are some "work arounds" for the 3D20 built into the codebase. The 3D45 seemed much more forgiving of regular Gcode in my previous tests, whereas the 3D20 has caused several lockups and reboots that were worked around (and now works great with).

Hopefully we don't need to do that.

Also, someone needs to pull down the codebase and get it updated with master branch, in that PR.

I have access to a Dremel 3D45 if this gets picked up again.
