  • y u no make delta robot?

  • @aradioactivedonut Speed is important but positional accuracy is more important. Cartesian wins in terms of cost and size.

  • @alansawula How difficult would it be to fit an extruder for solder paste and have the suction/extruder share the same pump?

  • Very nicely done! Do you have a plan for how parts will be transferred from reel/tape to the needle? Can't wait to see how this project develops.

  • Does anyone know you get the timing belt pulley from? (The one that is directly mounted to the servo on the Z axis) I'd really like to know.

  • Ha, I definitely need to subscribe to this channel!

  • put more videos of it in full speed. it is great!

  • Very nice. Elegant solution. Can the machine place a component on a board? Does it understand the orientation of the chip? I would like one of these myself.

  • @burkina07 Thank you! To answer both of your questions, yes it will, but the software is not yet written, I will post a video when it is presentable. I would like to be able to sell kits in the future since sourcing many of these parts costs a fortune in shipping from many different locations, and bulk discounts make a big difference on final cost. Will keep you posted.

  • Very nice. If you need any small 3D printed prototype parts in ABS send me a CAD file and I'll print and mail the part to you. I'm building a combo 3Dprinter/PaP and I keep going back and forth on using hobby servos, but I think your video "talked' me back into it.

  • @billyzelsnack Thanks! Hobby Servos are great for the short stroke axes, but I wouldn't be able to use them for x or y due to limited range of motion. Continuous servos would give you the range at a loss of positional control which is why I am using steppers. Best of luck with your build, send me a link when you can.

  • Alan, seriously, that has got to be the one of the coolest things I've seen all month. I'm going to have to build myself one of these... :)

  • @philpem Thanks!

  • awesome project dude,,,,wow it's impressive

  • @sigi199191 Thank you! Just wait till i finish the rest of it..

  • @alansawula can't wait to see the final version of it :)

  • wow great job.

    Is the webcam used for calibration?

  • @electrodacus Thanks! Yup the webcam is for calibration and correcting position and angle after picking up a component. It isn't integrated in the system yet but I have run tests with the machine and openCV and it seems promising. Very dependent on lighting so I will need to build a ring light for the camera.

  • @alansawula You can try to remove the IR filter on the webcam the camera is more sensitive to IR usually the filter is on the lens on the side with the sensor is usually a square piece of glass that looks purple at light or it can be on top of the sensor. and you can use some IR LED if more light is needed.

  • Great job. I have been thinking that it's time for people to start exploring a DIY PNP. Let us know when you start a site for collaboration on all the pieces that will make this functional. (software, etc)

  • @EdEstes Thanks! Will do!

  • Very, very nice job. Beautiful use of low cost design. What are you using for drive electronics? If you wanted a really simple board that could do 2 axis of stepper and up to 7 RC servos, check to the EiBotBoard, sold by SparkFun for $50.

  • @brianschmalz THE BRIAN SCHMALZ???!! :) You will be happy to know I am using two EasyDriver boards for this machine, thanks for making that board! I will check out the EiBotBoard, I have heard about EggBot but not looked into the EiBotBoard yet. Currently I have an Arduino decoding serial messages and signalling the stepper driver boards and servos, so I will need to move everything to one board. Thanks for the positive feedback, it goes a long way.

  • @alansawula I am VERY happy to hear that you're using my EasyDrivers. Very sweet. The Arduino works just fine too - I have nothing against it. Did you start with any Arduino code for your stepper control, or was that something you came up with all on your own?

  • @brianschmalz The code is all from scratch although I am using the servo library. I didnt show it in the video but It will rapid from any coordinate to any coordinate, moving all axes at the same time, that was a bit tricky to figure out but I used micros() to make a pseudo-scheduler loop to adjust the step timing during the move so I could accelerate the stepper motor.

  • awesome project. At the end of the video when it goes pick the small component, it's very fast, it's really really fine speed

  • Awesome work man! Is there a (English) forum that people are going to that are working on DIY PNP's?

    THanks!

    gg

  • @GeorgeGraves Hey! Thank you! I came across your brass etched stencil on the adafruit forums earlier today and I am very impressed! I can't wait to try that out. As far as I know there isn't a DIY PNP forum, it would be great to have a place to bring together some of the people that are working on this kind of thing. Thanks again.

  • Great aproach, great idea for the double bearings, etc. Setup a blog or collaboration website, I can help with professional plastic parts, etc.

  • @aherrera63 Thanks! I was originally going to use aluminum angles like buildyourcnc(dot)com, but I wanted to simplify it and I thought v-groove bearings would be too expensive (>$8), I may switch to v-groove later if i can justify it. The bearings in this video are very common and can be found for $0.50 on ebay in larger quantities.

  • @aherrera63 I appreciate the offer of help, I'll let you know when i have a blog/wiki set up or have designed a plastic part that's ready for professional production.

  • Great work! Do you have a build log somewhere?

  • @FPCoA Thanks! I don't have a build log at the moment but I have been keeping a record of the rationale for design decisions. I'll put it up someday soon,

  • I like it man you are about to make it I would like to get in touch with you for some chat and yet I wish to build one of those
