avoid skipped steps without over heating

many company's make small self adhesive heat sinks for computer RAM and after having some trouble with skipped steps and over heating from turning up the current to prevent them i found that the heat sinks stuck to the makerbot steppers work wonders and keep the motors cool. they allow you to run the steppers with more current and avoid overheating.
