Affordable Camera for Prusa Connect - ESP32 Camera - Chris's Basement 2024

[@mbdulka]

No clue why Prusa doesn't make this an accessory (at least) to buy out of the box, but great video thank you.

[@ChrisRiley]

Thanks for watching!

[@corwyn33]

I finally got this working with my Prusa Mini+ with the base attachment. Took me a while to modify the arm assembly to integrate with the base.

[@ChrisRiley]

Nicely done!

Now I have a project for the weekend, Great work as always!

[@ChrisRiley]

[@SoulacroupLesCombes]

Beautiful. Very accessible explanation. Thank you so much for your effort.

[@ChrisRiley]

You're very welcome!

[@eugene3d875]

Awesome walk through, thanks for detailed explanation!

[@ChrisRiley]

Glad you found it helpful!

[@herr_rossi69]

I've been using the Esp32 cam for a few months now. It works perfectly most of the time and is perfectly fine. Only sometimes I have problems with the WiFi even though the router is close by.

[@ChrisRiley]

Nice, great that it's mostly working. I am going to be testing antennas for sure.

[@herr_rossi69]

@@ChrisRiley The problem is re-soldering the resistor so that the external antenna works. Damn small that thing.

[@Michi_84]

Thank you for the video. When I read about it on the Prusa blog, I thought it was too complicated at first. But it seems to be quite simple when you look at it that way. I also ordered an ESP32 Cam with USB and the 6 resistors. I hope I can get it to work, then I can watch my MK4 printing via PrusaConnect! :)

[@ChrisRiley]

Glad it was helpful!

[@markrussell9719]

Fantastic Video - Just what I was lookin for, Thank you.

[@ChrisRiley]

Awesome!

[@tg_73]

Try to get one with a wide angle lens, I suggest at least 90 degrees. Most of the modules come with something around 68 degrees I think. I've had one for many months using an early version of the firmware. The narrow angle is annoying, particularly when the default print location for an XL is front left. You can also buy an additional wide angle camera module (just the camera with it's tiny ribbon cable), then swap it, if you have good eyesight and dexterity. Super cheap on Ali.

[@ChrisRiley]

Awesome, I would love to try that. Do you have a link to the wide cam?

[@andrewmoore5712]

Just got my XL and this worked great, Thank you Chris

[@ChrisRiley]

Great to hear!

Thanks so much!

[@TerryGilsenan]

I have these on all my Prusa's. both MK3S+'s and MK4's. All running PrusaLink, and all PrusaLinks connected to PrusaConnect. I also installed neopixel and jq and I am showing printer state by querying the PrusaLink API, parsing the result and driving a ws281x LED strip accordingly..: Blue heating, White printing, Green Cooling, Orange paused, and red flash for ERROR.

[@ChrisRiley]

That's a great idea! Those are handy little cameras!

[@grininventor]

I really like the color coding for the printer state. Do you have a more detailed explanation (GitHub or something like that) ?

[@icenode]

Appreciate the video! I built one of these a few weeks ago but the wifi connection was unusabley poor. You can add a wifi antenna, but it involves some really fiddly soldering that I don't think I got right. It's frustrating Prusa still don't have an official solution available for such a basic thing.

[@ChrisRiley]

I hear you, I am hoping they will release something that works out of the box soon.

[@icenode]

@@ChrisRiley They mentioned in a blog comment that they are working on one, it's just taking a frustratingly long time. :) I should have added, an ESP32 camera is still a great, affordable solution, just as long as you have a good wifi signal near your printer - mine's sadly in the attic!

[@mrbilky]

This was great I did start out following another youtube vid not saying it was wrong just saying it did not work for me this was straight forward and to the point not sure what I'll use it for as I am currently happy with my cam setups on my 4 machines but like the option of another angle from the stock locations!

[@ChrisRiley]

Awesome, hopefully this one is helpful.

[@HReality]

This is great! I have a handful of these lying around. Now all I have to think of is an alternative, maybe using a 5v Buck converter and wiring it to the Prusa PS so it’s not relying on outside power. I just checked.. I got the 4 resistor model so won’t be ‘exactly’ like this but I’ll still make it work :)

[@ChrisRiley]

Awesome, yes, it can be done but there are extra steps I have some as well. The guide does a pretty good job at explaining it.

[@Defiance85]

Since a lot of people have issues with detecting the wifi, I also had the issue and a more powerfull USB charger solved the issue.

[@ChrisRiley]

Yes, thanks for posting, more power has solved most of the problems I have encountered.

[@craigrogers8182]

Thanks! I've been waiting for you to do this. Now to find Mac instructions...

[@ChrisRiley]

Glad I could help! Mac is always a struggle for me. Maybe Bryan Vines can help us.

[@MakerMindNexus]

Another great video good sir.

[@ChrisRiley]

Thank you kindly

[@Chris0612]

I think you can grab 5V from the board somewhere, need to look it up tho

[@ChrisRiley]

Let me know, I couldn't find a good source.

[@Chris0612]

@@ChrisRiley I think the best way is to the 24 outputs and a step down converter.

[@UnlistedChannel932]

Very nice guide, thank you. I had some trouble where the camera didn't want to respond to the ip when connecting for the first time, but eventually using the prusa-32cam.local address worked after a few reboots. Question: How do you hang the external antenna? Mine is in the garage and doesn't have good signal, and I'm using the XL enclosure, which complicates things in terms of where to hang the antenna. Right now it's dangling out a hole in the top of the enclosure but that just looks like it's going to knock free from the pin inside the esp32 camera soon.

[@ChrisRiley]

I have the antenna wire running out one of the holes as well. I just made a quick L bracket to hold it in place.

[@fail_fast]

ngl I don't even attempt to figure this stuff out on my own anymore. I just wait for your videos 🤣

[@ChrisRiley]

Awesome! Glad the videos help!

[@earthman2005]

Hey Chris, Thanks for your outstanding work but after following your instructions and purchasing your recommended parts, I can not get the thing to connect to a wifi even though it's right beside me. I've tried different versions of the firmware but no go. Could you put a direct link to the firmware that you know works for sure please? I feel that might be the issue or Amazon sent me 3 duds.

[@ChrisRiley]

Sorry to hear that, these are the exact 3 files I use and haven't had any problems with. github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/download/v1.0.3/ESP32_PrusaConnectCam.ino.bin github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/download/v1.0.3/ESP32_PrusaConnectCam.ino.bootloader.bin github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/download/v1.0.3/ESP32_PrusaConnectCam.ino.partitions.bin Please let me know how it goes.

[@lukerogers3394]

Just make sure when your done and looking at the cam that you don't drop it. A new one is on the way

[@ChrisRiley]

Great tip! 😊

[@aModernGirlMakes]

Of course this has been updated on the GitHub since you published this. I can only find 1 of the 3 files. Do I not need the bootloader and the partition files?

[@ChrisRiley]

github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/tag/v1.0.3 Looks like they are flashing with the IDE now, you can always start with this version and the 3 files, then just upgrade to the new versions with the upgrade button on the web UI.

[@hectormontes123]

I still think that it is easier to install a VCR camera if you already have a closed circuit or a Wi-Fi camera on the market, which cost the same or less than these ESPs without complex configurations and you can monitor it from your cell phone or PC without having to be connected to have power or signal, this ESP camera seems to me more like a complex solution to a simple problem that Prusa did not know how to include in the XL, which for what they cost could have been included from the beginning for a few dollars more.

[@ChrisRiley]

They now sell a very inexpensive camera to do exactly that, I hope to see more of them come on the market.

[@WildcatCustom]

Awesome video and idea! It looks like the file have changed (new release) and they are no longer named anything close to the ones shown in the video. I am speaking of the .bin files. There is still a ESP32_PrusaConnectCam.ino.bin but the others are gone or named differently. How can I be sure I'm getting the correct ones and the order they should be in?

[@ChrisRiley]

Thanks! Check the previous repo, then you can use the interface to upgrade later if you need to. github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/tag/v1.0.3

[@GrahamDodd-l6e]

Hey Chris, great video as always. I was wondering how good the stream is when using WiFi. I know with my Pi's I get the occasional flicker and it's not so good when the bed is moving fast. I really need something good for my Mk3.9

[@ChrisRiley]

Thank you! They are a little slow, if you get flicker with the pi, it would probably be a bit worse with these. They are really only good for snapshots.

[@williamerskine6035]

Great information Chris (which you always deliver)! I'm inspired, but can the firmware setup of the camera, etc. be accomplished on a Mac as well?

[@ChrisRiley]

Thank you! I'm sure it can, I just don't know anything about mac, I wish I knew how to point you in the right direct. My friend Bryan Vines does all that good Mac stuff.

[@robertbaum4541]

Hello, I'm pretty new in this topic. I have a question. Which files do I have to use? There is just the "PrusaConnectCam.ino.bin". The other files a not there. Do I have to use some of the other files? I have the ESP32-S AI-Thinker

[@ChrisRiley]

[@Michi_84]

I have set up the ESP32 Cam so far. But I occasionally hear a whistling or sometimes a scratching or rattling noise from the circuit board (like an old hard drive). When I click through the menu in the CAM's web interface, the noises get louder. Is this normal or is the hardware I bought just bad? Bought on Amazon from diymore. If I set the resolution to 1600x1200, I also get extreme image errors when I click on "Start Stream" via the web interface.

[@ChrisRiley]

I haven't heard any interference from mine like this, but I'm not surprised. I wonder if you tried to ground the antenna if it would go away?

[@bigtony1313]

Great vid! I tried to update my drivers on my 6 resistor unit, but it doesn't appear to be taking. It just says it is "pre-installed". Any idea what I'm doing wrong? I've tried multiple cables, with no change. Still shows up as a generic USB Serial Port

[@bigtony1313]

So, for those who see this later on and are using Windows 11, it appears the drivers may already be there. It only shows up as just a generic "USB Serial Port", and it won't take the drivers as described in the video (it shows the "Pre-Installed" message), but you CAN flash the firmware to it through the same method as shown (the correct COM port should still come up). So don't get hung up on it showing CH340 in your device manager. Also, the module takes longer to update than the cuts in the video, so give it a couple minutes before you give up and refresh/restart. Anyway, great vid! Definitely helpful, and worth the effort!

[@ChrisRiley]

Thank you! Looks like you found the answer, thanks for coming back to post it.

[@Sergiodj453]

Very detailed explanation! Even I can do this LOL😂

[@ChrisRiley]

Lol! Thanks Sergio!

[@jericho347]

Can you hook more than one camera up with this method? Would like 2 camera angles for my xl

[@ChrisRiley]

Yes! Just configure 2 of these, then you can add them both in Prusa connect.

[@TheSoundsOfSirens]

I tried but there isn't much guidance for Mac OS? I can't flash the firmware onto the board

[@ChrisRiley]

I wish I could help, but I don't know anything about mac.

[@PatJones82]

Hey Chris, Thanks for the video. I used your links to purchase the 6-resistor model with the power board as a set, so I know I have the right items. Followed your directions and the PDF to the letter and all seems perfect...except no wifi. After I flash the firmware, it does not broadcast the SSID to connect to the camera module after flashing firmware. I tried a 2nd camera module set with the same result. I triple checked to make sure I have thee CH340 driver installed, using the correct Com port, and that I've downloaded the correct bin files. I've tried the entire process sever times with no success. Just not getting any WIFI broadcast from the camera module. Any ideas?

[@ChrisRiley]

What version of firmware are you trying? I was using this one, give it a try if this isn't the one you tried. github.com/prusa3d/Prusa-Firmware-ESP32-Cam/releases/tag/v1.0.3

[@PatJones82]

Thanks for taking the time to reply. Yes, that is the firmware version I’ve tried. I’ve tried others as well. I’m wondering at this point if I got a bad or counterfeit batch of esp32’s. Two of the three I got don’t ever offer an SSID. The last one occasionally provides the SSID after many tries, but even then, after joining my home WiFi and using it, I power it off and back on again and have to join the eap32 SSID and then rejoin it to my WiFi network again. It doesn’t save it for some reason. I dunno. I’ve programmed many ESP32’s to control led’s and never had an issue. Not sure what’s going on.

[@RenatoYamamoto481]

same here followed the tutorial 3 times to make sure i was doing it right even the firmware i got the one he used but no wifi

[@PatJones82]

@@RenatoYamamoto481 Sorry to hear you have the same issue. I finally figured out that I NEVER see the wifi on my home PC. But after about the third or 4th firmware upload attempt, I might see it on my iPhone. But only one time out of 3-4. I would then connect to the ESP using my phone, set the home wifi settings and get the camera working. Then I was happy... until I shut the damn esp32 off. When turning it back on, it sometimes connects to home wi fi and sometimes not. It's about 4 feet from my router so the signal is not the issue. 3-10 reboots later and it MIGHT connect to my home WIFI. So frustrating. I gave up on mine. Tossed all three in the trash. I'm hoping I got a bad batch, but still, I'll think twice before ordering more from Amazon. Give another device a try like a tablet or phone to see if you see the wifi there.

Is this camera suitable for printer enclosure? Because I’m worried for high ambient temperature in the enclosure during printing. I’d really appreciate if someone can help me answer. Thank you

[@ChrisRiley]

These should be good to run up to about 60c, it should work fine.

[@awilliams1701]

I seriously don't understand why prusa doesn't support a USB camera. I figured USB is USB and so I bought a USB-C camera from day one and it just collects dust. I might give this a try especially since I'm about to move the mk4 upstairs into the printing room. I'm almost done with my first MMU3 project. It's a diorama of Senko. It was definitely never intended to be FDM printed. LMAO So it's been a challenging print. After that I'll be moving the printer along side the mk3. And the mk3 needs to get the MMU upgraded as well. I might consider getting a mk3.5 now. The mk4 kind of makes me ignore the mk3. The 3.5 is a lot faster. I'm hoping it's higher quality too. Quality is the main reason why I don't bother. I may have my 2x sunlu S4 dryers side by side. And then a printer on either side of the dryers. That will give me 4 colors for each printer or 3 for 1 and 5 for the other. lol I'll probably never need to use my other dryers again. I can't imagine I'll ever need 10 colors at the same time. lol But with the printer upstairs, I won't be able to monitor it anymore. (unless I want to go upstairs all the time, which I don't)

[@ChrisRiley]

We might still see them be able to support a USB cam, you never know what updates they will come up with.

[@ethancohen6005]

I don't understand why prusa doesn't just build a camera into the printer. Plenty of other companies do, and from sourcing these parts ourselves, we know how affordable they are

[@ChrisRiley]

@@ethancohen6005 I think we will see them work that in at some point, even just one that does snapshots.
