+## Matrix Transforms
+
+A wrapper class, [GMatrix](../api-reference/mecode.md/#mecode.main.G) will run all move and arc commands through a
+2D transformation matrix before forwarding them to `G`.
+
+To use, simply instantiate a `GMatrix` object instead of a `G` object:
+
+```python
+# Replace this line
+# from mecode import G
+# with this one
+from mecode import GMatrix
+import numpy as np
+
+g = GMatrix()
+
+# set print speed
+g.feed(1)
+
+g.toggle_pressure(1)
+
+# save the current transformation matrix on the stack.
+g.push_matrix()
+
+# rotate our transformation matrix by 45 degrees.
+g.rotate(np.pi/4)
+
+# generate a serpentine path of length 25 mm, 5 lines, and 1 mm spacing
+g.serpentine(25, 5, 1, color=(1,0,0))
+
+# revert to the prior transformation matrix.
+g.pop_matrix()
+
+g.toggle_pressure(1)
+
+g.teardown()
+
+g.view('2d')
+```
+
+
+!!! Note "The transformation matrix is 2D instead of 3D to simplify arc support."

+## Multimaterial Printing
+
+When working with a machine that has more than one Z-Axis, it is
+useful to use the [`rename_axis()`](../api-reference/mecode.md/#mecode.main.G.rename_axis) function. Using this function your
+code can always refer to the vertical axis as 'Z' or whatever you provide as an argument. You can also dynamically rename the axis. For example, if you run `g.move(A=3)`-- this would correspond to a gcode command addressing the `A` axis: `G1 A3`. The latter approached is illustrated in the example below.
+
+## Example: Hollow Cylinder
+
+The following is an example wherein a hollow cylinder is printed, where each layer is composed of a different material.
+
+```python
+from mecode import G
+
+g = G()
+
+# COM1 = Pressure controller for material #1
+# COM5 = Pressure controller for material #2
+com_ports = [1, 5]
+colors = [(1,0,0,0.5), (0,1,0,0.5)]
+axis = ['Z', 'A']
+
+# offset distance b/w axis `Z` and `A`
+offset = 10 # mm
+
+# radius of cylinder
+R = 10 # mm
+
+# Print height
+dz = 1 # mm
+
+# number of layers
+n_layers = 20
+
+# set print speed in mm/s
+g.feed(10)
+
+# move nozzle to initial printing height
+g.move(z=dz)
+
+# move axis `Z` to starting position
+g.move(x=R)
+# g.set_home(x=0,y=0)
+
+# Print path strategy
+# 1. print first circle with material #1
+# 2. stop printing w/ material #1
+# 3. move material #2 axes to starting location
+# 4. start printing material #2
+# ...repeat for n_layers
+# turn pressure on (e.g., to start printing)
+
+def switching_strategy(j):
+ '''this function contains the logic for moving from one axis (nozzle 1) to another (nozzle 2)'''
+ # move active axis up and away
+ g.move(**{axis[j%2]: 50})
+
+ # move other axis to starting position
+ g.move(x=-offset if j%2==0 else +offset)
+ g.abs_move(**{axis[(j+1)%2]: (j+2)*dz})
+
+for j in range(n_layers):
+ g.toggle_pressure(com_port=com_ports[j%2]) # ON
+ g.arc(x=-R, y=R, color=colors[j%2])
+ g.arc(x=R, y=-R, color=colors[j%2])
+ g.toggle_pressure(com_port=com_ports[j%2]) # OFF
+ g.move(z=dz)
+ switching_strategy(j)

+## Direct control via serial communication
+
+With the option `direct_write=True`, a serial connection to the controlled device
+is established via USB serial at a virtual COM port of the computer and the
+g-code commands are sent directly to the connected device using a serial
+communication protocol:
+
+```python
+import mecode
+
+g = mecode.G(
+ direct_write=True,
+ direct_write_mode="serial",
+ printer_port="/dev/tty.usbmodem1411",
+ baudrate=115200
+)
+# Under MS Windows, use printer_port="COMx" where x has to be replaced by the port number of the virtual COM port the device is connected to according to the device manager.
+
+g.write("M302 S0") # send g-Code. Here: allow cold extrusion. Danger: Make sure extruder is clean without filament inserted
+
+g.absolute() # Absolute positioning mode
+
+g.move(x=10, y=10, z=10, F=500) # move 10mm in x and 10mm in y and 10mm in z at a feedrate of 500 mm/min
+
+g.retract(10) # Move extruder motor
+
+g.write("M400") # IMPORTANT! wait until execution of all commands is finished
+
+g.teardown() # Disconnect (close serial connection)
