M114

Example

• M114

This reports the X, Y, Z (,U, V, W, A, B, C if configured) and E coordinates to the host. The coordinates reported are those at the end of the last completed move.

For example, the machine returns a string such as:

C: X:10.000 Y:20.000 Z:5.000 E:51.000 E0:51.0 E1:0.0 Count 800 1600 2000 Machine 10.00 20.00 5.00 Bed comp 0.00

The first E value (without an extruder number) is the current virtual extruder position, and is included for the benefit of GCode senders that don't understand multiple extruders. The E0, E1 etc. values are for each individual extruder. The Count values are the microstep positions of each individual motor or motor group. The Machine values are the machine axis coordinates, which are calculated from the user coordinates by accounting for workplace coordinate offsets, bed compensation, axis skew compensation, babystepping and Z lift.

Note: there is no agreed definition of what the response to M114 should be. We try to keep the M114 response compatible with other firmwares as far as we can, but this is not always possible. Users writing applications which need to fetch current positions from RepRapFirmware 3 are recommended to use object model queries instead.
