| If you are powering Pixy through the Arduino cable instead of through the USB cable, or the [[wiki:v1:Powering_Pixy|power connector]], the servos are not going to get enough power. This is because the Arduino typically can't source enough current for the servos (1 Amp), and the Arduino cable tends to drop significant voltage. There are more details [[wiki:v1:Powering_Pixy|here]] on using the power connector, which is recommended in this case. | If you are powering Pixy through the Arduino cable instead of through the USB cable, or the [[wiki:v1:Powering_Pixy|power connector]], the servos are not going to get enough power.

| + | One way to check if you have a power issue: if you connect only one servo - that is, try unplugging one - does the issue persist? | ||

| + | If unplugging a servo solves it, that would point to current draw beyond the capabilities of your USB port or cable. | ||

| - | This should exercise the pan servo first then the tilt servo. The movement should be smooth and rapid. If not, make a note of which servo is acting strange. and send us an email describing your experience (<support@charmedlabs.com>). | + | This should exercise the pan servo first then the tilt servo.

| - | From PixyMon, bring up the [[wiki:v1:Configure_Dialog|Configure Dialog]] (the gear icon). In the "Servo" tab change the "Servo Frequency" to a lower value, from 100 to 75 or 60 and see if that improves the behavior of your pan/tilt servos. This suggestion is somewhat experimental, so please [[mailto:support@charmedlabs.com|send us a note]] if this helps! You can select **Action➜Restore default parameters** to get back if it doesn't help. | + | From PixyMon, bring up the [[wiki:v1:Configure_Dialog|Configure Dialog]] (the gear icon).
