How to connect a stepper motor to the driver, color coding of wires
The eternal problem, which wire to connect :)
1A - green
1B - black
2A - blue
2B - red
A + black
A - green
B + red
B - blue
A SPECIAL CASE
There are such motors Nema17 , whose wires do not have the same color as all :)
Marking for such wires I write in brackets:
A + black (red)
A - green (green)
B + red (yellow)
B - blue (blue)
I decided to update the old, already charred stand for the soldering iron. Simple and does not take up much space on the table.
The 3D model of the fan is very simple, easily wound on a collet clamp. I put it on my CNC machine. The first launch proved to be very good, all the chips are scattered to the sides, clean under the cutter.
The idea of assembling a homemade CNC machine appeared long ago. Lack of knowledge and necessary details. Today there is everything!
I made this CNC machine myself in 2015, videos of the same year. For a long time I was asked to make a video on the assembly of this machine, later my hard drive broke, by some miracle I found some materials on this machine on another medium. After almost 4 years I will publish the materials, as I did with my own hands a CNC machine tool from the available materials.
This is my first CNC machine assembled with my own hands from available materials. The cost price of the machine is about $170.
