Notes

The 'P' parameter is used tell the firmware about the hardware on which it is running, if RRF can't identify it. Should only be used in config.g, if you're having problems. If the P parameter is present then the integer argument specifies the hardware being used. The following are supported on first-generation Duets:

• M115 P0 - Automatic board type selection if supported, or default if not
• M115 P1 - Duet 0.6
• M115 P2 - Duet 0.7
• M115 P3 - Duet 0.85

The 'B' parameter is used on Duet 3 only, using RRF3. M115 can take an optional B (board number) parameter which is the CAN address of the board to be queried, default 0 (i.e. main board). Example:

M115 B1
