Now, i’m sure that each one of you has some stepper motors laying around and wanted to test them at a given time but never had the time to build a driver or to buy one. I had the same problem until i decided that is the time to build that cnc machine that am [...]
A while ago I started working on a CNC machine (milling machine or 3d plotter), something very simple, very cheap, something that can be built with the stuff you find at local stores, without using very expensive and complicated parts.
The frame of the machine is build from wood and use furniture rails as guides for [...]
this is a simple test for a driver for stepper motors it uses a l298 IC and runs great, i’ll post more details later.
and here is a unipolar motor controlled by the driver.
Also in this second video i use different sources for powering the circuit board and the power source for the motor.
