Macros are snippets of saved code which can be called with the click of a button instead of having to be typed repeatedly.

The Macros of the Controls pane section is where the user creates and stores these macros.

Macros Pane

Macros pane containing example macros for the Rostock MAX V2
Once macros have been created, they will appear under the Macros title.

The screenshot to the right shows an example of several macro buttons for the Rostock MAX V2.

Macro Editor

By default, the Macros section has no buttons.
To access the Macro Editor, click the pencil icon (Pencil-edit.png) next to the word Macros. This will open the Macro Presets window.

Macro Scripting (Starting in version 1.7)

Macro Scripting allows for the use of advanced functions in macros. These functions are called by using commands.

Syntax

To use a macro scripting command, begin the line with the following function:

; host.:

Then add a command and any applicable parameters.

; command([parameters])"

The result should look something like this:

; host.show_message(title:"Waiting for extruder to heat to [temperature].")

Commands

ding()

Play a bell sound.

show_message()

Shows the specified message.

Optional parameter variables (content must be in quotes):

  • title: [main text to show]
  • image: [a url of the image you wish to show]
  • wait_ok: [script execution will wait for the user to click 'ok']
  • repeat_gcode: [gcode to repeat until expire time reached (separate lines with a |)]
  • expire: [the max amount of time to run repeate_gcode or show this message]
  • count_down: [show a timer counting down from this time]

choose_material

Shows the choose material window.

Optional parameter variables (content must be in quotes):

  • title: [main text to show]

Example Script

The following is an example of a script used for loading filament:

; host.choose_material(title:"Choose the material that you are loading.")

M104 S[temperature] ; start heating up the extruder

; host.show_message(title:"Trim the end of the filament to ensure a good load.", image:"https://cdn.instructables.com/FSW/FEGA/HN4ZL57T/FSWFEGAHN4ZL57T.MEDIUM.jpg", wait_ok:"true")

M302 S0  ; Allow extrusion at any temperature
G91                 ; Relative positioning
; host.show_message(title:"Put filament into extruder and click Continue.", repeat_gcode:"G1 E.1 F150|G4 P10", expire:"90", image:"https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/5035400628/original/20150903_115628.jpg?1441307271")
G90                 ; Absolute positioning
; host.show_message(title:"Loading filament...", count_down:"28")
G92 E0              ; reset the extruder position to 0
G91                 ; Relative positioning
G1 E100 F1200       ; extrude the filament 
G1 E100 F1200       ; extrude the filament 
G1 E100 F1200       ; extrude the filament 
G1 E100 F1200       ; extrude the filament 
G1 E100 F1200       ; extrude the filament 
G4 S1               ; wait for move to finish

M302 S150  ; Set cold extrude temp back to reasonable
; host.show_message(title:"Waiting for extruder to heat to [temperature].")
M109 S[temperature] ; heat up the extruder

; extrude slowly so that we can prime the extruder
; host.show_message(title:"Click 'Continue' when filament is running cleanly.", repeat_gcode:"G1 E1 F300|G4 P10", expire:"90")

G4 S1               ; wait for move to finish
G90                 ; Absolute positioning
G92 E0              ; reset the extruder position to 0

M104 S0             ; turn the extruder temperature off
