Holy god. That was an impressive build before you added "Oh and there's an automatic drill and dust collector in here DONT WORRY ABOUT IT" Very neat. And yes, those tiny motor driver boards tend to handle a lot less than they say they're rated for. The rating in a lot of listing is peak current. I exclusively get ones with thermal shutoff and automatic restart nowadays. They're usually only a few bucks more, but will start working again quickly if overheated.
Excellent integration of the hydrocoptic marzlevanes with the x-y coordinate ambifacient waneshaft! Side fumbling in the cup's differential girdlespring seems to be effectively prevented.
This is such a cool a well done project. Good job! I've had problems with those red little motor drivers as well. And as someone who works in industrial automation I appreciate the Estop button.
It’s a great video, but there’s something I don’t get: Why not use peristaltic pumps and a simple flow sensor (if needed)? I love your explanations and ideas. You treat your viewers like we actually want to learn. I also love that you show us all the problems and your process of solving them.
The big thing that I found when researching peristaltic pumps is that the flow rates were somewhat low. I needed to dispense 250 ml of fluid in a few seconds. The upside, though, is the consistency of the flow rate. The machine that I saw used parastaltic pumps for the mixers it worked pretty well for the non carbonated mixers, just slow. Carbonated mixers, however, didn't have the best performance. As the fluid sat in the lines, the CO2 would come out of solution and stall the pump. Hope that sheds some light on my thought process. Thanks for watching!
You make one 10 minute video of project this size? Other youtubers would make 5 to 10 episode series even smaller projects. It would be awesome to see more detailed what you are doing. You spent so much time with these, why let people see so little?
A better way to pump drinks is to have the drink in a sealed chamber (such as a plastic bottle) and then pump air into the bottle, forcing the liquid out of a tube that is submerged in the liquid
Keep working on it! Replace the motor drivers with better ones, add a weigh scale to the cup holder, maybe make threaded adapters for different types of bottles so you can use the ones off the shelf instead of the plastic bottles. Maybe add a metal straw that goes all the way up to the top (bottom) to replace the air in the bottle. Try microstepping to make the motors quieter, find the resonances of your frame that make it rattle loudly and avoid those in your drive controller.
You applied so many things i could never understand to make the over engineered drink dispensers with way to many points of failure There was no need for tokens, big bright drink buttons would have worked, the cup did not need to move if you piped each bottle to dispense in same locations and how wasnt there a single solenoid valve on this build, you just need two cups on a scale one to be your measuring cup, counter balanced by an almost full measurement cup, when your actual mesurement cup it filled it becomes heavier then the counter weight cup lifting of a button triggering the solenoid to shut off the suplly valve moving this into a ready to tip state, all you need to do now is tip the mesured drink into a funnel into a small pipe or tubing to go to the cup once empty the counterweight will drop opining a valve to begin refilling. And buttons just tip all required drinks at the same time. The electronics would be simple all mesurement would be its own isolated piece per bottle, you could use a second button underneath where a full measured amount would be to check if it was ready then drink buttons would trigger check if required drinks are in ready staus then tip it
Hello, very cool video, I've wanted to build a machine like this for a long time, the dispensers are a cool idea. I can recommend the TMC2209 as a stepper motor driver, then the motors won't make such weird loud noises. Could you maybe publish the CAD files and a rough parts list. Thank you!
If you are really picky about motion accuracy, I recommend against the 2209. It only works properly if you turn off the fancy mode. When it automatically mode-switches (all the time without telling you) there is a motion error.
My imeadiate thought to the trilema would be why not just use an automated valve and flexible food grade tubing? Sourcing might be a pain but surely not more than making a Cartesian gantry system, not to mention lowering the points of failure.
Pretty cool Idea. I was wondering about your cost. Since the price of the alc. dispenser + the electronic and the servo are not that cheap. Especially if a foodsafe 500ml/min pump cost around 35€. And if your were concerned with the price of the build, why didn't you, or did you, try to use a servo for multiple dispenser?. I mean from a design point, I really like your dispenser design especially the locking mechanism and the contact plate. A cocktail machine is definitley also on my todolist.
Hey, genius. You don't need to move the cup with servos and you don't need pumps. Just dispense the liquids and let a large funnel bring it to the cup. Think smarter, not harder.
You would then get mixings of ingredients which wouldn't be good for kids getting non alcoholic drinks or potential allergy issues. Also that's nowhere near as cool or has as much showmanship as this design.
@@braedenhunt3677 Easy problem to solve. Since the machine is so much simpler, you can build a second one for non-alcoholic beverages and still come out ahead. And as for people with allergies, add a epinephrine option or simply tell them to drink bottled water.
@@braedenhunt3677 You could also have a rinse basin so after a drink is dispensed the funnel is flushed out with clean water. That's still less complex than moving the cups. On the other hand, I think it looks way cooler to have the cup go for a little ride. The rube goldberg aspect of it is what makes it interesting.
Thanks for watching! The big thing I found when looking at peristaltic pumps was flow rate. I was looking to dispense 250ml of fluid in somewhere around 5-10 seconds. I didn't find many 1500-3000 ml/min pumps that looked right for me. Parastaltic pumps do have the upside of consistent flow rate through so maybe if I found the right pump?
Interesting how far is the gap between "it works in my tests" versus "it works when it matters".
So true

I got the cheap ones and ran them at 40% of rated current. Lesson learned
@@BuiltDifferentDesigns And please consider some TMC2209's or other stealthchop driver, they're so much quieter.
Like self-driving cars, bartending robots are feasible if an “attendant” is present.

The lesson here is : always bring replacement parts ! (Although I have no idea how much these cost, that may have been too expensive)
Yea that was one thing that didn't make it into the video. I had replacement parts but I could not find them 😖

Congratulations on your marriage, hope all goes well.
This is pretty cool! I would love it if you were able to open source the design or even put it behind a paywall or something, so I could make my own!
Lesson learned: Drinks on tap
Stretch goal: Read datasheet on cooling requirements not youtube videos and diy 3d printer guides.
expensive food grade pumps not necessary. peristaltic pumps my guy. they are so cheap.
thats what i came here to say.
