Expected behaviour: while (auto)extruding the new filament, the nozzle should not move. It should move (from filament replacement position to printing position) only after the user has confirmed the successful filament replacement and extrusion.
Actual behaviour: while (auto)extruding the new filament, the nozzle moves from filament replacement position back to printing position.
So the extrusion step is mixed with the movement required to go back to the printing position.
The provided code seems to be working but probably a better fix is required.
Sanity Check for LCD_FOR_MELZI would fail with "Please select no more than one LCD controller option" any time #define LCD_FOR_MELZI was enabled in Configuration.h, even if there were no other LCD options enabled.
Ideally, it should be calculated based on Z steps per unit so that each
babystep corresponds to around 0.025mm. Smaller than this is largely
insignificant for typical layer heights.
* Add MAX7219_DEBUG to Travis CI testing
* Tweak config and use standard pin naming for MAX7219_DEBUG
* MAX7219: Apply coding standards, use macros, etc.
* Make code work...
* Add Max7219 LED Matrix Debug Support
The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.
The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.
* Try to keep Makefile up to date.
When M405 is used it changes 'volumetric_multiplier[FILAMENT_SENSOR_EXTRUDER_NUM]' value. When M406 disables M405 it leaves the value unchanged.
This PR applies 'calculate_volumetric_multipliers' in M406 instead of resetting it to 1.0 because M200 may not be compatible with M405 hence I'm sure to restore anyway with correct value.
