Posted on May 17, 2011 at 10:19have you checked the microcontroller receives the 5V supply voltage? If this is ok and you have the ST7 programmer, you can try programming the uC with the stepper.s19 file that comes in your C:\Program Files\PractiSPI...
Posted on May 17, 2011 at 10:16Microstepping technique consists in positioning the stepper motor rotor in an intermediate positions between two ''full step'' positions. The ability of this positioning is given by providing two different current inte...
Posted on May 17, 2011 at 10:14The only difference is the size of integrated power mosfets (i.e. maximum current). Choosing between L6235 and L6229 and the package type (SO, PowerDIP, PowerSO) take into account power dissipation more than rated curr...
Posted on May 17, 2011 at 10:14Hello, Since the driver gets damaged after some time and not immediately, it looks like to be an effect of high current/temperature. Try using 5.6nF instead of 68nF on EN pins. This should lower the r.m.s. value of the...
