M574 is "invalid M code" - why?

Noob to RepRap Firmware here. I'm setting up a Duet 0.6 for a Monoprice Mini Select because I fried the OEM controller. (FPGA closed source. Bah.)

At this instant I'm starting my way through the Duet commissioning process, interactively through the through Arduino Serial Monitor. I downloaded the SD contents from RepRapPro, though it appears that the same version is available on RepRap directly. (Which seems to be what was already on the SD card.)

Entering M119 shows me the current endstop state correctly, but M574 (endstop config) gives me "invalid M Code: M574".

M115 shows "FIRMWARE_NAME:RepRapFirmware FIRMWARE_VERSION:1.09 ELECTRONICSuet (+ Extension) DATE:2015-04-21".

What have I overlooked?

You are using a very old version of RRF that doesn't support the M574 command. See [forums.reprap.org].

RRF is currently V1.17. Maybe it's time to update the firmware. There had been many new and rewritten M-commands in the mean time.

Thank you both! Much better so far. (In fact, the endstops work as needed - no need for M574 now! )
Cheers!

You may find it easiest to generate the configuration and homing files using [configurator.reprapfirmware.org] if you are not already.
