G-code

G-codes are commands that we write and send to the printer in order to execute the movements of the axes and the extruder.

One of our first few G-codes

Below are a list of commands we regularly use:

  1. G0 – movement of linear axis
  2. G1 – movement of extruders
  3. G28 – homing of X, Y, Z axes (X0 Y0 Z0 position)
  4. G92 – set absolute extruder position (extruder, in this case, is our stepper motor which allows the drawing in and dispensing of liquid)
  5. M203 – to overwrite the maximum feedrate of the axes (in order to increase speed beyond the original settings
  6. T0/T1 – tool change for pipette plunger and eject plunger
