pin header for connecting DueX5, DueX2 or Duet Breakout Board, for additional stepper motors, heaters, temperature sensors, endstops, probes, fans etc. Pins can also be connected to individually for various additional functionality The following changes were necessary due to component availability issues, they do not result in functional changes to the design:. The Duet 2 WiFi has a WiFi module, the ESP8266. This is another 32-bit microcontroller with its own flash storage area, which is where the WiFi connection details are stored. It runs its own firmware, which occasionally needs to be updated. The Duet 2 Ethernet has a W5500 TCP IP processor on board which handles the low level Ethernet networking functions. Installation of both the WiFi and Ethernet modules on the same board at the same time is not supported.

Whether you're looking for a dual laptop monitor for everyday personal use or for completing school work on the go, the Duex Lite attachable monitor for laptop is a lightweight, slim, portable solution for a double laptop screen. The VFAN voltage can be selected by a jumper as VIN, 12V (internally generated) or 5V. ONLY ONE JUMPER SHOULD BE FITTED. Using more than one jumper could cause permanent damage to the DueX2/5 and/or the Duet 2. Stepper motor connections. Z MOTOR has two 4-pin KK headers, wired in series, for convenient connection of two Z axis stepper motors to ZA and ZB. If you only have one Z-Axis stepper motor, connect it to ZA connector and ensure jumpers are installed on the ZB connector; without a second stepper motor or the jumpers in place on ZB, ZA will not function. The DueX5 is an expansion boards for the Duet 2 Wifi and Ethernet. It provides up to 5 additional stepper, heater etc channels to allow for 3D printers or other machines with more axis, multiple drivers per axis, tool changers etc.Giuliano Moschini has created a model based on the Duet 2 WiFi model for the Duet 2 Ethernet available here ¶ Physical connections ¶ Wiring diagram ¶ Revision v1.0 and later It is also possible to mount the two boards side-by side with power connectors next to each other, but in this case the 50-way ribbon cable needs to be at least 200mm long instead of the standard 100mm. ¶ Cooling For these revisions forward the only difference between the DueX2 and DueX5 is only two stepper drivers are populated on the DueX2. The maximum recommended power input voltage is 25V. This is a permanent limitation, because the TMC2660 drivers are rated at 30V when supplying power to motors. ¶ Firmware notes The PWM channels for servos or other uses are shared with the heaters. DO NOT HAVE A HEATER PLUGGED INTO A CHANNEL YOU CONFIGURE PWM. Doing so will cause the heater to heat in an uncontrolled manner and potentially cause a fire.

Up to 7 additional stepper drivers, of which up to 5 can be TMC2660, as offered by optional DueX5 expansion board

The Duet 2 WiFi and Ethernet are the 2nd generation of Duet 3D motion control electronics. They are an advanced 32-bit controller for 3D printers and other CNC machines. ¶ Features Changed to a resettable VSSA fuse. Now if the thermistor inputs are connected to VIN, the VSSA fuse should reset rather than needing to be replaced. The MCU driving the Duet boards has considerably more inputs and outputs than are used on the main board. Many additional lines are available on the expansion connector. Powerful Connectivity – Features two USB-C ports with pass-through charging, so you can charge devices whenever and wherever you want. For legacy reasons, the pins on the Duet 2 and Duex PCBs and wiring diagram are labelled in a manner similar, but not exactly the same, as the RepRapFirmware 3.x pin name format. For example:

Caution! On early production (v0.6, v0.7) DueX2 and DueX5 boards, the VIN and GND markings on the underside of the board are incorrect and should be swapped over, so GND is the terminal that is also marked -, and VIN is the terminal that is also marked +. Caution! The signals on D7, D8 and D9 are all at 3.3V. The Step, Dir and Enable signals are an extension of the signals coming from the Duet over the 2x25 expansion header, with no additional voltage translation or protection. The Stop signal is a duplication of the one found on the corresponding endstop connection on the Duex. If you want to use them take the same precautions as if you were plugging directly into the expansion header of the Duet. • Switch to DueX2 mode The Duet 2 WiFi and Ethernet supports power distribution to and control of three heaters: a heated bed (assumed to be the highest current draw with a maximum of 18A) and two extruder heaters. These are fed from the 12/24V circuit, but the PWM switching is carried out by MOSFETs on the ground, so if necessary they can be run off different voltages. Very high power bed heaters should probably be supplied independently and switched with a SSR. Port (non MDIX). Connect to an Ethernet switch, hub or MDIX enabled laptop port. If connecting to a non MDIX enabled port use a crossover cable. Orange LED on Ethernet port indicates Ethernet enabled, green LED indicates network activity. Heater channels 3-7 are available as 5V active-high signals on the PWM1 - PWM5 connectors respectively. On the DueX2 versions before 0.8a, only heater channels 3-5 are available on PWM1 - PWM3. Caution: the heater output terminals will also be driven by the PWM signal or servo pulses.The maximum recommended power input voltage is 25V. This is a permanent limitation, because the TMC2660 drivers are rated at 30V when supplying power to motors. ¶ Electronics power consumption We’re an online magazine dedicated to covering the best in international product design.
