* fix spacing
* Support BABYSTEP_XY in M290
* Not just Z
* Extend M290 for BABYSTEP_ZPROBE_OFFSET
* tweak
Changes to support NEOPIXEL LED strips
- Support for different NEOPIXEL as defined in Adafruit_NeoPixel.h
- ability to setup startup brightness
- ability to define sequential/non-sequential transition of color change during heating-up
- additional parameter to M150 P<brightness>
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.
* 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.
