Tool Definitions
This guide will explains the default tool definitions for the QuadFusion and explains how to change tools. This can be useful to create complex mixing and switching prints. This guide is not for beginners
Default Tool Definitions
QuadFusion Tools:
T0: Top LeftExtruder Drive 0
Heater 1
T1: Bottom LeftExtruder Drive 1
Heater 1
T2: Bottom RightExtruder Drive 2
Heater 1
T3: Top RightExtruder Drive 3
Heater 1
As seen above, the QuadFusion has four different extruder drives and two heaters. The current configuration is set-up to make all tools heated by Heater 1, while the Bed will be heated by Heater 0.
Tool Definition Command M563
M563The M563 command allows you to define a tool, it has the following parameters:
Pnnn: The tool numberS"toolname": The tool nameDnnn: The assigned extruder driveHnnn: The assigned heater numberFnnn: The fans mapped to the tool.
The extruder drive numbers start from 0 and immediately follow the X, Y and Z axes stepper motor drives on the Duet Board. You can configure the order of these drives with the M584 command. If you were looking at your tools in the config.g, they would look like this:
Defining Your Own Tools
Defining your own tools is useful to create prints that switch colors in the middle of a print. To define a new tool enter the M563 command in the configuration file, then follow it with the extruder drive and heater number that you would like to use. Such as:
Mixing Ratios
To enable mixing rations for ta specific tool. Enter the M568 command with the tool number (Pnnn ) and the enable parameter (Snnn ). For example, if I wanted to enable tool mixing for tool 3 I would enter the command M568 P3 S1 .
To configure the actual tool mixing ratio, use the M567 command. This will tell the firmware to use one stepper motor drive to move more than the other one when handling an extruder move. M567 Pnnn Emmm:kkk:llll:iii where nnn represents the tool number. And the rest of the letters the tool ratios of the specific extruder drives. The total of the mmm, kkk, llll and iii parameters should add up to 1 in order to produce a normal and expected extrusion flow rate.
