Custom Tool Setter Position

This documentation is for a in-development feature, and may be incomplete/inaccurate. Please proceed with caution.

The location of the tool setter can be customized using the configuration elements coordinate.probe_mcs_x and coordinate.probe_mcs_y. Normally the location is set by way of reference to the toolrack but setting these two configuration keys you can use a specific MCS location.

The easiest way to set the coordinates is have a tool in the collet, and jog the spindle down so that it's above but not touching the tool setter. In the Controller take note of the MCS X and Y locations. These are the positions in small grey text in the tool bar.

Highlighted is the MCS Position of the spindle as shown on the Controller in small grey text

Store the settings running the below commands substituting 123.123 with the actual x and y position values. Do note that as these will be in the MCS coordinate space, so the values are expected to be negative.

config-set sd coordinate.probe_mcs_x 123.123
config-set sd coordinate.probe_mcs_y 123.123

reset the machine to apply the setting, and perform a tool calibration to check the location. Make small adjustments by eye as required.

Details of the current tool setter position configuration can be viewed using the command M493.4:

M493.4
current tool offset [-67.880] , reference tool offset [-67.880]
no one-off tool setter position offsets configured
Tool setter position (MCS): X[-3.300] Y[-14.900] Z[nan]

Off Center Tool Measurement

Large tools such as face mills with cutters that are not in the center can be probed off-center by using the parameters X/Y/Z on the M491 command.
