| Why so few low-end "manual" pick & place machines on the market? |

Wow so I'm a bit late in just discovering your awesome curio pick and place project! I wonder would you have any more information you could share on how you modified the curio to install the vacuum to pick up the parts and also what python tool you used to plot out the movements of the curio? |

Already 3 years ago I mentioned a pantograph in this thread. Today I bumped into the Panto Probe. I still believe it's best to combine these ideas. You use an X-Y gantry to get a big range, and you use the pantograph to d the final sub millimeter precision placement. Another way is to make the "storage area" of the raw SMT parts movable. I have seen several designs which put the SMT parts on a rotating platform. With this you can pick many different SMT parts from roughly the same spot. I do like the simplicity of using a (camera) ball joint, but moving your SMT part while keeping it vertical is also an advantage. This could be made by putting two pantographs on top of each other and connecting them with the right sort of linkage. And now for some fun Idea, * Start with a simple XY gantry controlled by stepper motors. You can buy these for around EUR 150 They are often combined with a laser and run on GRBL. * Connect the PCB to this XY platform, and then connect it to Interactive HTML Bom. Interactive HTML Bom is a KiCad plugin that helps with assembly, by for example highlighting all the places where to put 100nF decoupling caps (or any other part) * The X-Y gantry can now move the PCB to roughly the spot where the next part needs to be placed. (with forward / backwards buttons, use the mouse to select other things) * Make a rotating platform to store your SMT parts. This is 10mm or so above the PCB, so it can slide under it. * Now you have both the location to "pick" and the location to "place" in almost fixed locations. * For the rest, a pantograph type of movement can be used. |

I am interested in real user experiences how long you can use it and the muscle pain next two days. |
