* Heater power reporting. Useful for PID monitoring.
* PID tuning
The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.

* M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
* M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2 also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
* M220 - set build speed mulitplying S:factor in percent ; aka "realtime tuneing in the gcode". So you can slow down if you have islands in one height-range, and speed up otherwise.
* M301 - Set PID parameters P I and D
* M221 - set the extrude multiplying S:factor in percent
* M400 - Finish all buffered moves.
Temperature variables:
* M301 - Set PID parameters P I and D
* M302 - Allow cold extrudes
* M303 - PID relay autotune S<temperature> sets the target temperature. (default target temperature = 150C)
Advance:
* M200 - Set filament diameter for advance
* M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
* M205 - advanced settings: minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
EEPROM:
* M500 - stores paramters in EEPROM
* M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).
* M502 - reverts to the default "factory settings". You still need to store them in EEPROM afterwards if you want to.
* M503 - print the current settings (from memory not from eeprom)
