Can you provide a link to what you bought?
I bought a very small stepper motor with a controller from ebay, but when I regulate the speed down, it became very jerky. So I now need to know if there are any ways to make microstepping by adding a small electronic circuit.
Are ther anybody here who can help me?

stepper motor is not good, try high torque hybrid servo or servo motor
Those round tin-can steppers are OK for turning a flag around. They are no use for a CNC.

I think you need to buy a microstepping drive.
Like this TB6600 Single Axis 4A Stepper Motor Driver Controller 9~40V Micro-Step Module | eBay
and a pulse generator something like this
5V 10A Stepper motor driver controller Speed Regulator Pulse Signal Generator | eBay
or like this

I'm pretty sure that the above pieces would work with your motor, you would only have to set the maximum current correctly on the driver.
OK, given the application I don't think my solution above will work. It is possible that the U1 chip on the board that you have is programmable for micro stepping. You should do a bit of research on that part number and see what it will do. A PIC micro computer might be capable of doing it also.
Yes, that chip is a microcontroller and is programmable. There is proabaly a programmer unit available for them, but I can't help you there.

A PIC or anything similar, with some FETS, would be fine. You may be able to find the SW and circuit on the web.

You could use an arduino. Try sparkfun or adafriut. There are many tutorials available
