First of all sorry to ask about A4988 calibration it seems this is a common topic and I should be able to solve it from research but I just can't.
I have setup for calibration per PololuPres_V3.pdf however I have since learned this is not an official Pololu document.
I am using an Arduino Uno, A4988 driver, this is my driver data sheet http://www.reprap-diffusion.fr/uploads/ ... -1684A.pdf
and I am using a 12vDC 5A laptop power supply.
I have set my multimeter in series to measure amps and cannot seem to get anything above 100mA from turning the potentiometer.
I have probably turned the potentiometer far too far in one direction or I'm doing something really stupid but I am worried that I am going to damage something.
The driver is also getting too hot to touch.
Thanks for reading
