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.
I made this powerful lawnmower myself for the village, there is always a lot of high grass, which is not rational to fight with the usual manual trimmer. This animal mows down everything, tough grass, small trees, levels of hills, covered with moles, and even turns old bricks out of the ground.
Today, instead of round guides, the printer received square, using a conventional aluminum profile tube with a cross section of 20 * 20 mm. Bearings roll along the pipe 623zz. All plastic parts were printed on the same printer before it was altered.
I need a tachometer to calculate some mechanisms. For example, to calculate the speed of a robot vacuum cleaner, you need to know the rotation speed of the electric motor and, based on this, calculate the gear ratio of the gearbox.
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.
