Revision as of 22:26, 23 September 2021
This is the new default extruder as of Oct 2021. (It is named after Caltrain.)
Specs
- Orbiter Extruder
- Aluminum Metal Tool Plate
- ?? [grams] without wiring harness
- accepts V6 and Phaetus Firefly Groovemount-based tools
Software Configuration
Here are the general operating conditions:
- 681 [steps/mm] (aka: "Esteps")
- 450-500 [mA] Peak Current
- 0.03 - 0.05 [sec] Pressure Advance
- 0 [mm] nominal X offset from carriage
- 36.62 [mm] nominal Y offset from carriage
Duet Configuration
Note that the items shown in < > signs are placeholders and should be replaced with the values you actually have. (Remove the < > signs too!)
Finally, note that the order of these commands inthe config matter. You cannot refer to sensors or heaters in later lines of the config if they have not been created in previous lines of the config
Define a Temperature Sensor
The Duet ecosystem assumes that each extruder has a single temperature sensor. Define this extruder's temperature sensor index.
M308 S<sensor_index> P"1.temp0" Y"thermistor" T100000 B4725 C7.060000e-8 A"<sensor_name>"
Note that the Y"thermistor" can be other types of sensors, which may have different B and C settings--or none at all! The above settings apply to a generic E3D thermistor, usually the default in a hotend setup. There is a strict syntax of name choices that can be found in the M308 documentation.
Define a Heater
The Duet ecosystem assumes that each extruder has a single heater cartridge. Define this extruder's heater index.
M950 H<heater_index> C"1.out0" T<corresponding_temperature_sensor_index>
The C"1.out0" string encodes the Canbus board address followed by the output name. The example above creates a heater and assigns it to expansion board 1's output 0.
Define a Motor Drive
The Duet ecosystem assumes that tools are connected to single motor drive. Motor drives are numbered starting from 0. Define a motor drive with:
M569 P<motor_drive_index> S<1 or 0>
Motor direction can be set to S0 forwards (default) or S1 backwards.
Define a Tool
Tools are numbered starting from 0. Define the tool index, tool name, and assign a corresponding motor drive, heater, and fan:
M563 P<tool_index> S"My Chocolate Extruder" D<motor_drive_index> H<heater_index> F<fan_index>
Nominal Offset
Define the tool's XYZ offset from the ZProbe's trigger location. These can be set to the nominal value and adjusted later when you align tools.
G10 P<tool_index> X0 Y32.75 Z-1.23
Pressure Advance
Optional: define this extruder's pressure advance value. This can be omitted (implying a value of 0), but a value of 0.1 seems to be a good starting point for this particular extruder.
M572 D<motor_drive_index> S0.03
