* G76: calibrate probe and/or bed temperature offsets
* Notes:
* - When calibrating probe, bed temperature is held constant.
* Compensation values are deltas to first probe measurement at probe temp. = 30°C.
* - When calibrating bed, probe temperature is held constant.
* Compensation values are deltas to first probe measurement at bed temp. = 60°C.
* - The hotend will not be heated at any time.
* - On my Průša MK3S clone I put a piece of paper between the probe and the hotend
* so the hotend fan would not cool my probe constantly. Alternatively you could just
* make sure the fan is not running while running the calibration process.
*
* Probe calibration:
* - Moves probe to cooldown point.
* - Heats up bed to 100°C.
* - Moves probe to probing point (1mm above heatbed).
* - Waits until probe reaches target temperature (30°C).
* - Does a z-probing (=base value) and increases target temperature by 5°C.
* - Waits until probe reaches increased target temperature.
* - Does a z-probing (delta to base value will be a compensation value) and increases target temperature by 5°C.
* - Repeats last two steps until max. temperature reached or timeout (i.e. probe does not heat up any further).
* - Compensation values of higher temperatures will be extrapolated (using linear regression first).
* While this is not exact by any means it is still better than simply using the last compensation value.
*
* Bed calibration:
* - Moves probe to cooldown point.
* - Heats up bed to 60°C.
* - Moves probe to probing point (1mm above heatbed).
* - Waits until probe reaches target temperature (30°C).
* - Does a z-probing (=base value) and increases bed temperature by 5°C.
* - Moves probe to cooldown point.
* - Waits until probe is below 30°C and bed has reached target temperature.
* - Moves probe to probing point and waits until it reaches target temperature (30°C).
* - Does a z-probing (delta to base value will be a compensation value) and increases bed temperature by 5°C.
* - Repeats last four points until max. bed temperature reached (110°C) or timeout.
* - Compensation values of higher temperatures will be extrapolated (using linear regression first).
* While this is not exact by any means it is still better than simply using the last compensation value.
*
* G76 [B | P]
* - no flag - Both calibration procedures will be run.
* - `B` - Run bed temperature calibration.
* - `P` - Run probe temperature calibration.
