M202 - Set max travel acceleration
in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
M203 - Set maximum feedrate
Sets the maximum feedrates that your machine can do in mm/min.
Example: (M203 X200 Y200 Z300 E10000)
Note: this should be in units/minute, just like the F code.
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
M205 - Advanced settings
minimum travel speed S=while printing T=travel only, B=minimum segment time X= maximum
xy jerk, Z=maximum Z jerk, E=maximum E jerk
M206: Set home offset
Example: M206 X10.0 Y10.0 Z-0.4
The values specified are added to the endstop position when the axes are referenced. The same can
be achieved with a G92 right after homing (G28, G161).
With Marlin firmware, this value can be saved to EEPROM using the M500 command.
A similar command is G10, aligning these two is
subject to
discussion.
M207: Calibrate z axis by detecting z max length
Example: M207
After placing the tip of the nozzle in the position you expect to be considered Z=0, issue this
command to calibrate the Z axis. It will perform a z axis homing routine and calculate the distance
traveled in this process. The result is stored in EEPROM as z_max_length. For using this
calibration method the machine must be using a Z MAX endstop.
This procedure is usually more reliable than mechanical adjustments of a Z MIN endstop.
M208: Set axis max travel
Example: M208 X250 Y210 Z180
With Marlin firmware, this value can be saved to EEPROM using the M500 command.
The values specified set the software limits for axis travel in the positive direction.
With Marlin firmware, this value can be saved to EEPROM using the M500 command.
M209: Enable automatic retract（Retraction）
Example: M209 S1
This boolean value S 1=true or 0=false enables automatic retract detect if the slicer did not support
G10/11: every normal extrude-only move will be classified as retract depending on the direction.
M220:set speed factor override percentage
Example: M220 S80
S<factor in percent>- set speed factor override percentage
M221: set extrude factor override percentage
95
