servo pins in Duet ethernet

Hi to all

Like in ramps board they are any servo pins in Duet ethernet board?

The pins for controlling additional heaters on the expansion connector can be used as servo control pins. They have 3.3V signal levels, but most 5V servos seem to work with a 3.3V control signal. See https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins for how to configure them. You can also get +5V for servo power from the expansion connector.

The DueX2, DueX5 and external stepper interface boards have servo connectors with 5V signal levels.

Caution: large servos sometimes feed large power surges into the 5V power rail. Therefore we recommend that you connect a 200uF or greater capacitor between the +5V and ground terminals of the servo, to help absorb these surges.

Hi dc42,

its can be use for tool change using servo?

Yes, by putting appropriate M280 commands in the tool change macro files.
