Revision to Duet 2 Maestro Hardware Overview

Ian A-S

}
-== Firmware and interface features ==
+== Firmware notes ==
* Compatible RepRapFirmware versions: RRF 2.x, RRF 3.x
-* Connect via PC, tablet or smartphone on the same network to the [[Duet Web Control v2 and v3 (DWC) Manual|Duet Web Control]] web interface. There is no need for an app install, internet connectivity or cloud service to sign up for yet you can control your printer, upload and start prints from the browser.
-* Setup your printer and update the firmware through the web interface. No need to compile your own firmware.
-* Most printers supported: All common 3D printer geometries are supported, with easily modified configuration templates for popular designs. Along with 3D printers a wide variety of CNC machines and laser cutters can be controlled.
-* Firmware support for multiple tools and mixing nozzles
-* Advanced Calibration Support: Use any of several types of Z probe combined with advanced firmware features for true bed levelling, delta printer calibration, and/or mesh bed compensation.
== Operating limits ==
|! Z probe connector
| IN pin is 30V-tolerant
+|--
+|! 5V current limit
+| 2.0A total on 5V and 3.3v, including the internal current consumption (around 200mA), any PanelDue or other display, and any endstops/Z probes that draw significant power.

+== Physical properties ==
+
+=== Dimensions ===
+
+There are four 4mm clearance holes at the corners of the board. You can use M4 screws to attach the board to a panel or an enclosure, make sure to use nylon washers under the screw heads. The mounting centres are 115mm x 92mm, full dimensions are shown in the diagram:

+
+The diagrams show the mounting hole points in the format X,Y so the bottom left hole is at X=4mm, Y=4mm, the top left is at X=4mm, Y=119mm and so on. The board has 1 additional holes at (63.4,64.3) for mounting the temperature daugherboard.
+
+=== 3D model ===
+
+A 3d model of the Duet 2 Maestro has not yet been produced.
+
+=== Mounting ===
+
+The mounting holes are isolated and not plated through.
+
+Please note:
+
+* If you mount the board on a metal surface, use standoffs to ensure that the back of the board cannot short against the plate. A minimum standoff length of 5mm is advised, however larger is preferred for better cooling.
+* '''Do not use metal washers under the mounting screws''', or screws with large heads (e.g. button head). Nylon washers are recommended. With a metal washer there is a risk of creating a short.
+
+=== Cooling ===
+
+The PCB is designed to transfer heat from the stepper drivers and power mosfets to the underside of the board. Therefore your mounting method should encourage good airflow underneath the board.
+
+If you mount the board vertically, make sure that cool air can enter at the bottom of the board, flow upwards behind the board, and escape at the top. Convection cooling will usually be sufficient, but if you are using high stepper motor currents then you may wish to add a fan below the board to encourage the upward flow of air. Make the spacing between the back of the board and the panel or enclosure large enough to allow a good flow of air.
+
+If you mount the board horizontally then a cooling fan is recommended, especially if there are other heat-generating components in the vicinity such as power supplies, SSRs or stepper motors. Position the fan to blow air underneath the board (optionally along the top as well), especially along the row of stepper driver chips and between the power input and bed heater terminal blocks.
+
+'''Important'''! The higher the motor currents you set, the more important it is to cool the board.
== Connectivity ==
The Duet 2 Maestro also support the [[PanelDue]] colour touchscreen. Connectors for a 12864-type mono graphics display and rotary encoder are also provided.
