#### M665: Set delta configuration

**Parameters**

**Lnnn**Diagonal rod length^{2}**Rnnn**Delta radius**Bnnn**Safe printing radius**Hnnn**Nozzle height above the bed when homed after allowing for endstop corrections**Xnnn**X tower position correction^{1}**Ynnn**Y tower position correction^{1}**Znnn**Z tower position correction^{1}

**Examples**

- M665 L250 R160 B80 H240 X0 Y0 Z0

Set the delta calibration variables

**Notes**

^{1}X, Y and Z tower angular offsets from the ideal (i.e. equilateral triangle) positions, in degrees, measured anti-clockwise looking down on the printer.

^{2}In RRF 2.03 and later, multiple L values can be provided, for example **L260.1:260.2:260.0**. The values are the lengths of the rods to the X, Y and Z towers respectively. If more than 3 values are provided, the firmware assumes that there are as many towers as L values up to the maximum supported (currently 6). The XY coordinates of the additional towers must be defined subsequently using the M669 command. If only one L value is provided, the machine is assumed to have 3 towers with all rods having the same length.
