Introductions: - This filament run out sensor unit is designed to detect whether your printing is run out of filament. - During printing, if the unit detected that there is out of filament it will send a signal to the main board. - With correct firmware settings, the printing will be paused until the operator reload the filament and resume the printing. Features: - It works with all available materials;flexible,clear,opaque,filled,etc. - The unit can handle as many filaments simultaneously. As soon as one of them will be missing, the unit will send a message to the next one, up to - your main board. - Two screws are provided so you can install it where you want. - Works with almost any printer. - Durable injection modeling casing and industrial grade components. Specifications: Supply Voltage: 3.3-5V Operating Temperature: below 80￢ﾄﾃ Filament Diameter: 1.75MM(1-2MM) Filament Presence: low Filament Absent: high(equal to Supply Voltage) Primary cable: 80cm extension cable: 20cm PTFR tuble: 50cm Cable color: Red — 3.3-5V Yellow/Blue — Signal Black — GND 1. Install: Please install the unit after the spool and before your extruder. Fix it on your printer and along with the path of the filament is recommend. Pay attention to the direction indicated by the arrow on the body. Inserted the 4mm PTFE tube to both sides of the unit for guiding the filament and help to reduce the friction. 2. Connections: Servo pins always have the right pins:5V, Ground, and Signal. Most endstop pins will have the same 3 pins, and sometimes only Signal and Ground. If you only have these two, there should be a 5V somewhere else on your main board. In theory, you can choices any input pins on your mainboard for the signal. 3. Firmware configuration: Marlin: Make sure your firmware has the filament runout feature, you need Marlin 1.1.0-RC7 or newer. If you are using an older version, contact your 3D printer manufacturer or update your firmware configuration manually. 4. Expansion: If you want to install more than one unit on the same printer just connect the unit one to each other then connect to the main board at the end. They just parallel connection on the circuit Level. So the signal output can’t tell which one is run out actually but you can check the flashing LED on the unit to find out. Package Included: 1 x Filament runout sensor

Original JYETech 13805K DSO138mini DIY Digital Oscilloscope Kit SMD Pre-soldere Package weight: 0.13 kg DSO138mini brings in the following improvements: Better structure and smaller size. The bulky pin-headers connecting the LCD and main board in old DSO138 has been eliminated. The soldering of these pin-headers has being found problematic for beginners. USB or battery powered. This makes the scope much more convenient to be used as a portable device. New version analog board (PN: 109-13801-00H, aka "H version") can accommodate a battery charger JYE118 (see here) to make the device more practical. External trigger input. This input can accept a TTL or LVTTL signal as trigger source. Serial output of waveform data. This means captured data can be saved and displayed by PC. For example, this photo shows a captured single byte (0x35) sent from a serial port at 115200bps. This photo shows the same waveform displayed on PC using Gnuplot. General controller. The main board can be used as a general purpose control board with LCD display. MCU ports were brought to board edges for easy connection to the target system. There are a few optional parts that can be chosen to make the oscilloscope even more complete: BNC connector. The kit comes with a two-pin header for the simple hook probes (see the manual). This connector replaces the two-pin header and will allow you to connect to standard professional BNC probe. Standard BNC probe.

3D Printer Controller RAMPS 1.4: The RepRap Arduino-compatible MEGA Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino-compatible Mega with the powerful Arduino-compatible MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino-compatible MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Features: USB type B receptacle. SD Card add on available. Fits 5 Pololu stepper driver board. LEDs indicate when heater outputs on. Expandable to control other accessories. Heated bed control with additional 11A fuse. Option to connect 2 motors to Z for Prusa Mendel. I2C and SPI pins left available for future expansion. It has provisions for the cartesian robot and extruder. All the Mosfets are hooked into PWM pins for versatility. 3 mosfets for heater / fan outputs and 3 thermistor circuits. Fused at 5A for additional safety and component protection. Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs. Servo style connectors are used to connect to the endstops, motors, and leds. These connectors are gold plated, rated for 3A, very compact, and globally available. Arduino-Compatible Mega 2560 R3: Fully compatible with original Arduino MEGA 2560 R3, with this product, you are able to use all the Arduino open source platform to create or learn interactive objects. Compared with UNO R3, this is with main Chip ATmega2560, with more I/O Pins, and additional 10 PWM output, of course, the EEPROM is also with larger space. A4988 StepStick Compatible Stepper Motor Driver Module: A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and +- 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing. A4988 surface mount QFN package (ES), a size of 5 mm x 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation.

Perfect match with: (package does includes) Motor driver with 4.5A: MKS TB6600 3D printer motherboard: MKS-Gen Feature: In current 42 motor-driver of 3D printer on the market is that the direct primary IC connect to motor driver IC, the current consumed by each interface will not exceed 2MA. The MKS Gen motherboard that we design has signal port, which can output the signal from motor driver. We suggest using 4988, 8825 etc. motor driver. Generally, what 57/86 stepper driver inputs, is the optical coupling isolation, mainly to  prevent from interference. Each motor driver has 3 inputs. EN enable port controls motor switch. PUL pulse port controls the movement of the motor position or speed, DIR direction interface controls movement direction of the motor. The driver current of general optical coupling interfaces is around 10MA, one  driver actuates one motor. One driver consumes most of 30MA control current,  after X, Y, Z, E  connect to four general 57/86 motor driver that will need 100MA current at work. It is easy to burn the 3Dprinter IC control board if build connection directly but for not  enlarge current. Note: MKS CD expansion board can adjust the flow control signal, to avoid motor drive with optical isolation generate press on main IC, therefore, Ramps1.4, MKS Gen and other main board with five large motor drive can  operate  completely without pressure.   Usage: Insert MKS CD directly into the driver slot, leads the control signal from the above white card port. Please note the direction of the socket. Package includes: 3 x MKS CD 57/86 Stepper Motor Driver 3 x Cable
