Wiki ▸ [Z-Code Documentation](Z Code Documentation) ▸ Command Overview

A list of all the commands I was able to find. "?" means that I was able to find the commands in .zcode files, but I don't know what they do. "??" means that I was not able to find the commands and I don't know what they do.

01

move to, extrude and nozzle fan2 speed

01 type bitfield [unknown coordinate] [x-coordinate] [y-coordinate] [z-coordinate] [e-coordinate] [fan2 speed]

Table of parameters:

name	Type	Content
type	uint8_t	seems to be the line-color for the preview in Z-Suite. 01 - blue (object), 02 , 0A-0D - grey (raft layers), FD-FF - invisible (new layer), ...
bitfield	uint8_t	sets which parameters will be changed in the command
unknown coordinate	int32_t	only appears in conjuntion with the z-coordinate. Maybe it is the z-coordinate for another mechanical z-axis design(M200 v3)
x-coordinate, y-coordinate	int32_t	position of the x- and y-axis. 65,536 seems to roughly correspond to 10cm
z-coordinate	int32_t	position of the z-axis. 65,536 seems to roughly correspond to 8cm
e-coordinate	int32_t	extruder position
fan2 speed	uint8_t with 3 empty bytes following	speed of fan2 (fan that cools down the print surface at the nozzle)

Note: All parameters after the bitfield have a 4-byte length. The first byte stores the first 8 least significant bits, the second byte the next 8 bits and so on.

Examples

set speed of fan2 to full power:

command	type	bitfield	fan2 speed
01	FF	20 (00100000)	FF 00 00 00

move 10cm (~65,536) on the x- and y-axis and extrude:

command	type	bitfield	x-coordinate	y-coordinate	e-coordinate
01	01	0B (00001011)	00 00 01 00	00 00 01 00	00 D0 00 00
