If you add coordinates, only coordinates added will be homed. For example "G28 X0 Y72.3",
only X and Y axis will be homed, no homing for the Z axis (numbers after X and Y will be
ignored).
G29-G32: Bed probing
G29 Detailed Z-Probe
probes the bed at 3 points.
G30 Single Z Probe
probes bed at current XY location.
G31 Report Current Probe status
reports whether Z probe is triggered. G32 Probe Z and calibrate with FPU
probes the bed at 3 points and updates transformation matrix for bed leveling
compensation.
Immediate G command
The below commands will be buffered and be responded only after all the previous buffered
commands are executed. So the main machine will wait until all commands are executed (latest
respond). These temporary stops will not affect the normal function of the machine.
Teacup Firmware
buffers G20, G21, G90 and G91.
G4: Dwell
Example: G4 P200
In this case sit still doing nothing for 200 milliseconds. During delays the state of the machine (for
example the temperatures of its extruders) will still be preserved and controlled.
G10: tool offset
Example: G10 P3 X17.8 Y-19.3 Z0.0 R140 S205
This sets the offset for tool (or in older implementations extrude head) 3 (from the P3) to the X
and Y values specified. You can put a non-zero Z value in as well, but this is usually a bad idea
unless the tools are loaded and unloaded by some sort of tool changer. When all the tools are in
the machine at once they should all be set to the same Z height.
Remember that any parameter that you don't specify will automatically be set to the last value for
that parameter. That usually means that you want explicitly to set Z0.0.
