*Look-ahead:*
|
|
||||||
|
Differences and additions to the already good Sprinter firmware:
|
||||||
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.
|
*Look-ahead:*
|
||||||
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.

Slic3r can find curves that, although broken into segments, were ment to describe an arc.

It leads to less over-deposition at corners, especially at flat angles.
|

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.
|
*Arc support:*
|

Also, less serial communication is needed.

To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.

*AutoTemp:*
|
*Temperature Oversampling:*
|

|
|

If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
|
To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.
|
||||||
Usually, higher speed requires higher temperature.
|
|
||||||
This can now be performed by the AutoTemp function
|
*AutoTemp:*
|
||||||
By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
|
|
||||||
|
If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
|
||||||
You can leave it by calling M109 without any F.
|
Usually, higher speed requires higher temperature.
|
||||||
If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec].
|
This can now be performed by the AutoTemp function
|
||||||
The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax.
|
By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
|
||||||
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.

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.

Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".

First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.

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.

First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.

This is useful, because the user gets a warning message.

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.
