3D Printed Solder Paste Dispenser with step Motor

grabcad

Preview: So far only a mechanical design because PCB is on the way from China. It's a remake of my 3D Printed Solder Paste Dispenser with a DC motor and gearbox.Motorized automatic solder paste dispenser. Easily printable on a 3D printer at home.Control with 32bit processor STM32F103C8T6, OLED display 128x32, Step Motor NEMA14 using motor driver DRV8825. Much more precise control of the pressure in the syringe gives better control over the amount of paste extruded.The buttons "PUSH" and "PULL" on the syringe ring are cut off from the back part of the control PCBIt is necessary to delete the extension "delete.txt" from the sticker files, otherwise the files could not be uploaded to the GrabCAD library.More work will follow soon, more on my page https://github.com/Jarins?tab=repositories, where there will be production documentation including video. That is, as soon as I publish it there. :-)
