This list is Pololu trillion rupiah , or ramps short. It was designed as a low-cost small package RepRap needs to accommodate the entire electronics . Oblique interfaces with the powerful Arduino MEGA platform Arduino Mega , and have plenty of room for expansion. On the stepper drives and a Arduino MEGA shield extruder control electronics for easy maintenance , replacement parts , upgrades and expansion capabilities , including plug-in modular design . In addition, some Arduino expansion boards can be added to the system , as long as the main ramp plate is saved to the top of the stack .
The board is mainly based on Adrian ‘s Pololu_Electronics and work Tonok ‘s . The proposed anti- Vick copper etching method . Vick is also inspired by the work of EasyDrivers . Adrian’sPololu_Electronics circuit design mainly based on Joaz RepRapSource.com provide initial pin definitions and many design improvements. Too much inspiration , advice, and from Prusajr, Kliment, Maxbots, Rick, and many other ideas RepRap community.
3D printers use LCD control panel, are ramps extension accessories. LCD control panel through which you can achieve spooling is the 3D model Gcode files are copied to the SD card, and then print the file via the LCD control panel. This version is an upgraded version of reprap smart controller.
Limit Switch Endstop:
Quality switching elements.
Customized high quality connection, using 22AWG wire, copper wire inside is very thick, can be resistant to current 2A, 300V voltage. An insulating layer over a wide range of temperatures, up to 80 degrees. Is the common connection of thin copper wire can not match. Not easy to pull off, plug it convenient, for ease of use, plug the other side to do the one, you can use the direct plug.
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 × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.
