-
-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.
-
-## Differences and additions to the already good Sprinter firmware
-
-### Look-ahead
-
-Marlin has look-ahead. While sprinter has to break and re-accelerate at each corner,
-lookahead will only decelerate and accelerate to a velocity,
-so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity.
-This is only possible, if some future moves are already processed, hence the name.
-It leads to less over-deposition at corners, especially at flat angles.
-
-### Arc support
-
-Slic3r can find curves that, although broken into segments, were ment to describe an arc.
-Marlin is able to print those arcs. The advantage is the firmware can choose the resolution,
-and can perform the arc with nearly constant velocity, resulting in a nice finish.
-Also, less serial communication is needed.
-
-### Temperature Oversampling
-
-To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.
-
-### AutoTemp
-
-If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
-Usually, higher speed requires higher temperature.
-This can now be performed by the AutoTemp function
-By calling M109 S<mintemp> B<maxtemp> F<factor> you enter the autotemp mode.
-
-You can leave it by calling M109 without any F.
-If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec].
-The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax.
-If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change.
-Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode.
-
-### EEPROM
-
-If you know your PID values, the acceleration and max-velocities of your unique machine, you can set them, and finally store them in the EEPROM.
-After each reboot, it will magically load them from EEPROM, independent what your Configuration.h says.
-
-### LCD Menu
-
-If your hardware supports it, you can build yourself a LCD-CardReader+Click+encoder combination. It will enable you to realtime tune temperatures,
-accelerations, velocities, flow rates, select and print files from the SD card, preheat, disable the steppers, and do other fancy stuff.
-One working hardware is documented here: http://www.thingiverse.com/thing:12663
-Also, with just a 20x4 or 16x2 display, useful data is shown.
-
-### SD card directories
-
-If you have an SD card reader attached to your controller, also folders work now. Listing the files in pronterface will show "/path/subpath/file.g".
-You can write to file in a subfolder by specifying a similar text using small letters in the path.
-Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".
-
-### Autostart
-
-If you place a file auto[0-9].g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu.
-First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.
-
-### Endstop trigger reporting
-
-If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port.
-This is useful, because the user gets a warning message.
-However, also tools like QTMarlin can use this for finding acceptable combinations of velocity+acceleration.
-
-### Coding paradigm
-
-Not relevant from a user side, but Marlin was split into thematic junks, and has tried to partially enforced private variables.
-This is intended to make it clearer, what interacts which what, and leads to a higher level of modularization.
-We think that this is a useful prestep for porting this firmware to e.g. an ARM platform in the future.
-A lot of RAM (with enabled LCD ~2200 bytes) was saved by storing char []="some message" in Program memory.
-In the serial communication, a #define based level of abstraction was enforced, so that it is clear that
-some transfer is information (usually beginning with "echo:"), an error "error:", or just normal protocol,
-necessary for backwards compatibility.
-
-### Interrupt based temperature measurements
-
-An interrupt is used to manage ADC conversions, and enforce checking for critical temperatures.
-This leads to less blocking in the heater management routine.
