- G38.2 straight probe now supported. Rough draft. May be tweaked more as testing ramps up. - G38.2 requires at least one axis word. Multiple axis words work too. When commanded, the probe cycle will move at the last ‘F’ feed rate specified in a straight line. - During a probe cycle: If the probe pin goes low (normal high), Grbl will record that immediate position and engage a feed hold. Meaning that the CNC machine will move a little past the probe switch point, so keep federates low to stop sooner. Once stopped, Grbl will issue a move to go back to the recorded probe trigger point. - During a probe cycle: If the probe switch does not engage by the time the machine has traveled to its target coordinates, Grbl will issue an ALARM and the user will be forced to reset Grbl. (Currently G38.3 probe without error isn’t supported, but would be easy to implement later.) - After a successful probe, Grbl will send a feedback message containing the recorded probe coordinates in the machine coordinate system. This is as the g-code standard on probe parameters specifies. - The recorded probe parameters are retained in Grbl memory and can be viewed with the ‘$#’ print parameters command. Upon a power-cycle, not a soft-reset, Grbl will re-zero these values. - Moved ‘$#’ command to require IDLE or ALARM mode, because it accesses EEPROM to fetch the coordinate system offsets. - Updated the Grbl version to v0.9d. - The probe cycle is subject to change upon testing or user-feedback.
