Example: M304 P1 I2 D3
Sets Proportional, Integral and Derivative values for bed
M420: Set RGB Colors as PWM
Usage: M420 R<Red PWM (0-255)> E<Green PWM (0-255)> B<Blue PWM (0-255)>
Example: M420 R255 E255 B255
Set the color of your RGB LEDs that are connected to PWM-enabled pins. Note, the Green color
is controlled by the E value instead of the G value due to the G code being a primary code that
cannot be overridden.
T: select tool
Example: T1
Select tool (or in older implementations extruder) number 1.
The sequence followed is:
1. Set the current extruder to its standby temperature specified by G10 (see above),
2. Set the new extruder to its operating temperature specified by G10 and wait
for all temperatures to stabilise,
3. Apply any X, Y, Z offset for the new extruder specified by G10,
4. Use the new extruder.
Selecting a non-existent tool (100, say) just does Step 1. above. That is to say it leaves all tools in
their standby state. You can, of course, use the G10 command beforehand to set that standby
temperature to anything you like.
Note that you may wish to move to a parking position before executing a T command in order to
allow the new extruder to reach temperature while not in contact with the print. It is acceptable for
the firmware to apply a small offset [by convention (-1mm x tool-number) in Y] to the current
position when the above sequence is entered to allow temperature changes to take effect just away
from the parking position. Any such offset must, of course, be undone when the procedure
finishes.
If the Z value changes in the offsets and the head moves up, then the Z move is made before the X
and Y moves. If Z moves down, X and Y are done first.
After a reset extruders will not start heating until they are selected. You can either put them all at
their standby temperature by selecting them in turn, or leave them off so they only come on
if/when you first use them. The M0, M1 and M112 commands turn them all off. You can, of
course, turn them all off with the M1 command, then turn some back on again. Don't forget also to
turn on the heated bed (if any) if you use that trick.
Extruder numbering starts at 0.
