FABtotum add-ons

Add-on IDs from 0 to 99 are reserved for FABtotum products. At present the following are recognized and officially supported:

ID	Name	Working mode
1	Hybrid Head	0 (Hybrid)
2	Printing Head	1 (FFF)
3	Milling Head	3 (CNC)
4	Laser Head	2 (Laser)
6	Printing Head PRO	1 (FFF)
7	Laser Head PRO	2 (Laser)

Third party add-ons

Third party add-ons can be identified with IDs from 100 to 255.

Add-on installation

FABtotum add-ons should always be installed by the UI to guarantee proper initialization.

In general the correct procedure to change add-ons is:

1. Disable current add-ons: M793 S0. All relevant IO pins will be disabled.
2. Possibly remove installed add-ons, head or bed.
3. Physically install new add-ons.
4. Set a convenient working mode with M450 Sxx.
5. Set an add-on ID with M793 Sxx.
6. Configure firmware.

Add-on documentation

For each supported add-on the following information is given. Developers of custom add-ons are encouraged to follow this layout when documenting their creation. Popular third-party add-ons may be included in FABlin wiki as a reference and as example of custom add-on development.

IO

Column	Meaning
#	Arduino pin number
FABlin pin	Pin name in FABlin source code
HW func	MCU subsystem enabled for the pin
dir	Pin direction (wrt MCU):
	← signal input
	→ signal output
	⇒ power output
HDB name	Pin name on HDB silkscreen
Application	Add-on function linked to the pin

Base configuration

Property	Value
Working mode	Working mode number
Add-on ID	Add-on ID

Hardwired configuration

For proprietary add-ons: Snippet of hardwired add-on configuration from firmware source code

Custom configuration

Additional configuration required

• For proprietary add-ons this is usally included in hard-wired add-on configuration and enforced or overridden by FABUI.
• For third-party add-ons this must be input manually or saved into a custom add-on profile on FABUI.
