The Asus MB169B+ is not strictly a sliding monitor. However, it’s one of the better options if you are in the market for a portable monitor that connects via USB-A. So, just if you have one of the older laptops, this portable monitor will do just fine. You can mount it on its cover and prop it up next to your screen. And the good news is that it’s not as pricey as its counterparts above. Up to 7 external stepper drivers when not using Duex expansion board. Signal levels are 3.3V. A 5-channel expansion breakout board is available to level shift them to 5V.
DUEX Max features a 14.1” full HD IPS display with an 85% screen-to-body ratio, perfect for 14” and larger laptops. DUEX Plus features a 13.3” full HD 1080P display that’s perfect for 13-14” laptops. Lightweight and with an ultra-slim profile, users can easily carry the DUEX and their device around without it weighing them down. For sporting applications where rebound is not a prevalent such as tennis standard Duex Panels maybe preferred. IAE are experts in sports mesh systems, the most commonly supplied is our Duex® Sports 868 Rebound. The rigid twin 8mm wire design has additional horizontal wires in the bottom 1200mm section of a panel. These additional wires reduce the panel apertures to 50 x 66m creating a robust ‘rebound’ surface, strengthening the bottom of the panel that receives the most impact. This dense double wire pattern can be continued throughout the full height of the panel if necessary creating a rigid wall of rebound mesh. The Duet 2 WiFi and Ethernet also provides connectors for several fans, some always-on and some PWM-controlled. These can be supplied with 12/24V or with 5V, or (since again the switching is by MOSFETs on the ground line) if necessary from user-supplied power inputs. DueX5 and DueX2 have undergone a number of minor PCB revisions, from the original release (v0.6) to the current (v0.11). All DueX revisions are compatible with all PCB revisions of the Duet 2 Wifi and Duet 2 Ethernet. • PCB revision v0.11If you have a slightly bigger laptop, the Trio Max sliding laptop monitor might prove to be the best option out there. This one is 14-inch and, like its counterpart above, mounts on the laptop lid. The primary advantage that it brings to the table is that you can attach an additional monitor, thereby upping the display count to 3. Cool, right? Important! The cables must be oriented as shown in the image in the Power wiring section, below. If you have a white pre-production Duet 2 WiFi then the 50-way expansion connector may be fitted the wrong way round, with the keyway on the side next to the edge of the board (wrong!) instead of away from the edge (correct). To fit the cable, you will need to file down or cut off the protruding key on the cable end. ¶ Power ¶ Power distribution I've had this thing for about 2 years now and have actively used it for 1, so it's doing well for the number of drops its had. It's never fallen more than 6", but even still the corner of a screen hitting a hard surface can easily break it. The Duet boards run on two basic power circuits. The digital electronics are supplied by a 5V circuit, which is internally converted down to the 3.3V levels that drive the MCU. This circuit also drives all the LEDs and sensors, and can be configured to feed the fans. The high-power devices, specifically the stepper motors and the heaters, are powered by a higher voltage, typically 12 or 24 V. This 12/24V circuit can be switched on and off through the PS_ON pin, if the power supply supports this (it may be a good idea to add such support through a relay, for safety reasons, if it doesn't) without interfering with the MCU at all. Alternatively, the Duet boards can draw power from this circuit to power the 5V circuit. The DueX2 and DueX5 expansion boards add 2 and 5 extra channels respectively. There are 2 more channels available on the CONN_LCD header, giving a total of 12 stepper channels.
When you need the screen to be extended, all you need to do is connect the monitor to your laptop, pull it towards yourself, and get going. Moreover, the display quality is quite decent, and the lightweight form factor means that it doesn’t add much heft to your laptop bag. Sounds exciting, no? 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.There are two modifications to do, both of which use jumpers on the DueX5 v0.11, but use drillable/solderable jumpers on the DueX5 v0.10 PCB. The first change is to change the board ID so that the Duet 2 thinks a DueX2 is attached, and the second is to disable the onboard drivers so that external drivers can be used.
RRF 3.x - Pull up resistors on Duet 2/DueX5 inputs should be configured for connecting a digital input (like a switch, BLtouch, etc) only on inputs not labelled "n"Stop (xstop, ystop etc). Easily pair your DUEX Max with any laptop or device, including a Nintendo Switch and select Android phones, via USB-C or USB-A connection. The boards all support connection to a computer over USB, using any standard 3D printer host control program. The Duet 2 WiFi can also connect to a secure WiFi network, while the Duet 2 Ethernet has an Ethernet port. The primary way to control these boards is with a web interface controlled through the network. Although they have removable on-board SD cards, the network interfaces provide fast enough file transfer that it is generally preferable never to remove the on-board SD card.RepRapFirmware 3 uses pin names for user-accessible pins, rather than pin numbers, to communicate with individual pins on the PCB. In RRF 3 no user-accessible pins are defined at startup by default. Both Duex® 868 and standard Duex® can also be supplied in a lighter 6/5/6 configuration, however IAE would always recommend using heavier 8/6/8 panels in a sporting environment. RRF 2.x - Logical pin numbers for RRF 2.x are not the physical pin numbers on the expansion header, or the internal pin numbering within the firmware. When on external 5V power with no connected devices drawing power from the 3.3V or 5V supplies, both the Duet 2 WiFi and Ethernet draw about 200mA average from the 5V supply with the network interface enabled. For the Duet 2 WiFi, the peak current when transmitting may be in excess of 300mA. ¶ Firmware notes
