We continued constructing the outer box. The frame had already been set up last week, so we began drawing laser-cutting diagrams(used acrylic board) for the box and plate holder. To draw the diagram, 2 of us measured the framework, confirmed the coordinates of screw holes. The other 2 modeled the plate holder.
We got our circuit boards we designed back , and we used high temperature soldering iron along with soldering tin to weld pins, resistance, etc. onto our boards. Now we saved ourselves efforts for connecting the boards ! We no longer need those crazy wires and tiny step motor driver.
We also learned to use Inkscape to draw laser-cutter diagrams. Red represents cutting through the line; blue represents vector engrave, and black represents raster engrave.
We got Seeduino board, motor, step motor driver, and a bunch of wires, and we researched to find each product's design drawing and data sheet. Due to a lack of knowledge about different pins' functions and crisscrossing wires, we made many mistakes without noticing.
