Step 23: Driver Part 4This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend
purchasing a kit that is very stable from our wide range of machines available.
The driver is almost to a completion! We have installed all of the tiny components. Now to the big components. This is the logical process of putting together any circuit kit. The small components are difficult to insert if the larger components are installed already. Believe me, I've tried. Especially if there are jumper wires or resistors needed underneath chips and sockets.

A very important process of this part of the electronics assembly is the testing. You have seen me test various components. First, for seeing if components are damaged or not. Second, to determine if solder flowed around the lead correctly and there is good contact. Now we will do a much more important test. The circuit, after the large capacitors are installed, needs to be tested to make sure that there is only a range of 5 to 5.2 volts. If it is higher, the driver chips can get damaged. After this, the driver chips will be installed which will conclude the driver assembly. What's remaining after the driver board? We will need to get into the wiring of the motors to the driver. Then, the power supply will get built (very dangerous). Somewhere in there I will build the router mount in which we will get into some mathematics (perimeter of a circle to find the radius, very simple stuff).
