Bird Feeder - The DIY 3D Printed Bullet Feeder

[@superxxl]

I've just started printing & collecting all necessary parts :) Great project!

[@amats3]

Cool. It’s the 1/2” brake line protector by gravel guard for 9mm. I added a quick disconnect for the slinky connection, designed a printable flange, made the collator plates drop in, beefed up the mount, adjusted the sensor so that it doesn’t need to be bent, etc. The 100 rpm motor on the old model didn’t work for me but the 10 rpm worked like a charm. I ran a case of 9 through it and got 100% nose up. 👍

[@guillaumegras4814]

Great works man !! I printed 2 of the older model but I redesigned some stuff to fit my need better. Your new model is great !! I will make one for sure.

[@leandrocaricato3259]

Hi there! Your work it´s amazing. ¿Are you going to make the manual drive version of this one also? Greetings from Argentina.

[@FrankPichler]

Also made a version of the optic sensor housing that screws together, no more zip ties. Let me know if you're interested. Love both of these feeders, thanks for all the hard work.

[@zsdewitt]

Please do share. [e-mail]

[@kurtlippert1537]

Hello, could you please send the link to the sensor housing with screws design? Thanks!

[@HeliRCWorld]

Hi is it possible to share the link to the file. I'm interested thanks.

[@kgchrome]

are there plans for a 308 or 223 plate?? or is the system not able to do longer/rifle bullets?? great job all around. i love passion projects that get to exercise the noggin.

[@PeekEngineering]

I second this comment! I have solidworks and was thinking about just making the holes smaller haha. Would that work?

[@pewpew7001]

Super great project. Many thanks for it! I agree with both of them. I am also looking for a possibility for 223. @DeWZ Could you help us further?

[@michaelhenderson5098]

I have the original model together and testing it now. So far, so good. Like you mentioned, the limit switch is kinda finicky. And since I use the Lee Loadmaster, I made a bracket that would allow the hopper to mount on a piece of 1/2 inch pipe. seems OK so far. Thanks for all your hard work. I think this new model is a little over my head. :(

[@zsdewitt]

Glad to hear the original works well for you for the most part though!

[@johnstuhlmiller6317]

Ali express has springs that work great for 9mm I think they are 14mm compression springs

[@Hitstrekker]

Why does the manual say ABS ! Can it not be produced in PETG too?, the reason i ask is that my original ammomike version that i printed was in PETG been going strong for many years. Is there a structural issue that i need to be mindful of?

[@alannagel4381]

Mine was printed in petg and it functions well

[@morpheus6d9]

Welcome back

[@zsdewitt]

Thanks! Been a minute.

[@morpheus6d9]

@@zsdewitt I'm thinking about printing one for 300 BO

[@zsdewitt]

​@@morpheus6d9Do it! I don't have any on hand, but if there's anything I can do to help, let me know.

[@TheOneTrueStoney]

Hey, great update. Even though I already have a bullet feeder, I might take on the project for fun. I do have a request, however. Can you put a link to the mirror you have mounted above your press to assist in monitoring the casefeeder? That is the only part I would really like, and my searching doesn't find one like that. Thanks!

[@alessandrominuti7305]

Congratulations. Beautiful project. Can you tell me what filament you used, brand and color. I thank you.

[@tymkiwp]

Very nice, can you tell me the size of the PCB?

[@toddneis4504]

Great Job. How do i order a pcb main board? Thank You

[@spiveyt]

Do you have extra PCBs you can sell with a markup?

[@mrboostification]

Hi very nice, where can i find the bom file for parts placement at jlcpcb?? can you help please

[@FrankPichler]

How did you get the IR sensor to work without a 10K ohm pull up resistor between red and white wires? Without the resistor mine would run for a bit then stop for half a second then run for a bit. it would run about 75% of the time but status light would always blink. works great now with the addition of the pull up res.

[@zsdewitt]

Interesting, I haven't experienced that nor heard of anyone else having an issue. I'm wondering if it could be the particular version of the optic sensor you're using?

[@FrankPichler]

@@zsdewitt Figured it out. Some break beam sensor use an Open collector configuration requiring a pull-up resistor. first I soldered one to the board and it worked great. But after further research I found that if you configure that input as a "INPUT_PULLUP" it uses the on board resistor. works great. it's line 45: pinMode(breakBeamPin, INPUT_PULLUP); (must be in CAPS)

[@HeliRCWorld]

​@FrankPichler thank that solved the same issue for me of stopping and spinning.

[@buddaett]

is this a Arduino board ?

[@cutalpha]

Would it be possible for you to use the extra parts you have to build extra PCBs that you can sell with a markup?

[@heldersantiago6515]

Just finished building mine. Everything is working fine except that that the motor loses steps when I load a decent quantity of bullets. Not filled to the brim, just a decent quantity. Im using the same stepper as in the video and all the same hardware. Ive upped the RMS value to max (1500) and turned the trim pot on the Bigtreetech 2209 driver to max and it still stalls, altough it is better now. Am I doing something wrong or maybe I should redesign it for a Nema 23 motor?

[@marcelo8038]

Hello, great project. I have to outsource the 3D Printed parts. What remarks should I pass to them (about infill, layer height, wall thickness, etc.)? Regarding the PCB, is there any particularly reason it is not enclosured ?

[@cbhill1]

Forgive my ignorance, but are the files used to make the components compatible with a resin printer along with filament type printers?

[@zsdewitt]

Good question, unfortunately, I have zero resin experience and can't weight in.

[@TheOneTrueStoney]

I have both, and it would be difficult to get a build plate big enough for these prints in resin. You'd likely also have to use your slicer to cut the larger parts into segments for reassembly, AND I'd suggest an ABS-like resin should you want to try. Having said all that, printing time would likely be greatly reduced!

[@cbhill1]

Fantastic input! Thank you for the information!

[@ThomasAugustyn-y2k]

were did you get the pcb from china have no idea to go about ordering one

[@purplearrow47]

Why did you put the mount on the wrong side

[@zsdewitt]

I'm not sure what you mean?

[@purplearrow47]

@@zsdewitt Thanks for replying. The mount has the adjustment controls facing away from the user when mounted on the non handle side of the dillon press. ie when facing the dillon press im looking at the back of the bird feeder, i think contols facing the user would be better.

[@GerhardWiese-px8io]

Hi, nice project, just wanted to know if you can make to PCB schematics available for the PCB bord I would like to make my own bord 🙏

[@zsdewitt]

Everything is available at github.com/DeW-Z/BirdFeeder

[@johnstuhlmiller6317]

Really good design although the plates need to be changeable. With a clutch. I’d also create a box for the bottom or side that houses the pwn and other circuit boards

[@judd_s5643]

Well I think you pretty much defined YOUR next project. You can use this design as a bases (but make sure you give proper credit!)

[@usmcfiredog]

Great work. Any update on the manual. Can the plate work with other calibers? Any plans or know where to get other feeder plates?

[@zsdewitt]

Sorry for the delay. I'm still working on a revised manual, but have you found the original?

[@usmcfiredog]

@@zsdewitt you mean the one on your website?

[@zsdewitt]

@@usmcfiredog it's on GitHub and Printables only right now. github.com/DeW-Z/BirdFeeder

[@HeliRCWorld]

So almost done with it just having a problem. Where it spins real slow stops then spins slow again just does that over and over. Hoping someone here has had a similar issue and might have a solution.

[@zsdewitt]

Have you made any adjustments to the firmware file?

[@JasperSandhu]

I'm experiencing that exact issue. Attempting to troubleshoot and hope to resolve it somehow.

[@JasperSandhu]

After some troubleshooting, it looks like the beam sensor was getting tripped, which was caused by poor quality beam sensors. I suspect you may be running into the same issue. The faulty beam sensors were only sending ~0.7 - 0.8V and is nearly a logic low and occasionally a logic high.

[@cynx6456]

Do you sell them by some chance?

[@spiveyt]

Where can I find links to the parts that need to be ordered? Your website links appear to be for the previous version. Thanks!!

[@zsdewitt]

Check out the manual that is on GitHub, it has a list of materials in it.

[@eladsinay6914]

HELP. so i started with trying to print the collator plate for the 9mm. right off the bat i keep getting one spot that doesnt print. i took pics but cant show here. ill try to explain it. so as it starts and makes the outer border where eventually the bullets will feed in to, one of those doesnt print. i tried three times and two different filaments and had the same issue i the same spot. can anyone let me know if they had the same issue and what that means?

[@zsdewitt]

Send the pictures to [e-mail] and I'll take a look.

[@kaziwill]

Need more calibers. Also, a clutch in case a bullet gets stuck

[@zsdewitt]

There's an option to use StallGuard in order to detect jams. If that isn't used, the stepper motor has a low enough torque setting that it'll just slip.

[@kaziwill]

@@zsdewitt lolz. okaaayyyy..

[@BamaDad]

@DeWZ do you know the inner diameter of the spring tubing? I may have a source. If you could measure it and reply I'll be happy to post the tubing source!
