| There are many things that can go wrong with a device like this. Things can get too hot, or too cold; things can move incorrectly, or not at all; things can move too far and jam against things they should never touch. | There are many things that can go wrong with a device like this.

| As mentioned above, it is critical that the thermistors and heaters are wired correctly, otherwise the heaters will not work properly. Things might stay cold, or get much too hot and cause damage. | As mentioned above, it is critical that the thermistors and heaters are wired correctly, otherwise the heaters will not work properly.

| An infrared thermometer is a handy tool for checking temperatures. These can be found for as little as US$20. Some of these have a laser pointer to help you aim the sensor. | An infrared thermometer is a handy tool for checking temperatures. These can be found for as little as US$20.

| - | If you tell it to move 1 cm in some direction, and it moves 2 cm or more instead, you may have one or more missing jumpers on the Azteeg controller.

| - | Not mentioned above is the universal failure mode, which is a failure of the Azteeg controller or a bug in its firmware (or even a bug or incorrect setting in the host software that is directing the controller through its USB port). This can result in a wide variety of symptoms, including all of the above and many more. | + | Not mentioned above is the universal failure mode, which is a failure of the Azteeg controller or a bug in its firmware (or even a bug or incorrect setting in the host software that is directing the controller through its USB port).
