RAMPS 1.4 Board :
The RAMPS 1.4 is Mega Pololu Shield, or RAMPS for, design to fit the entire electronics need for a RepRap in one small package for low cost. RAMPS interfaces an Mega with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Arduino expansion boards can be add to system. As long as the main RAMPS board is kept to the top of the stack.
Arduino Mega2560 :
Mega2560 is an ATmega2560 as core micro-controller development board itself has 54 groups digital I/O terminal (14 Pin PWM outputs). 16 sets of simulation than the input side, group 4 UARTs (hardware serial ports), using the 16 MHz crystal oscillator. With the boot-loader, download the program directly via USB without having to go through other external writer. Supply part of the optional USB power, or as an external power using the AC-to-DC adapter and battery.
Driver DRV8825 :
The DRV8825 are perfectly compatible with the A4988, but you should be careful which have to be assembled on the contrary.
It is recommend that, both 4988 that the 8825, with voltage 12 or 24 Volts and no more. With 24 Volts maximum speed is slightly higher. The 36 Volt is best not to use them because the 4988 don’t hold them right and the 8825 would work too close to the limit.You should not use them at current greater than 1 Ampere. Maximum 2 Ampere, but with every dissipators on drivers and a single fan that cools them all from above.
LCD 128×64 graphic Smart Display :
LCD 128×64 graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 20×04 dot matrix LCD display. You can easy connect it to your Ramps board using the “smart adapter” include.
After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design store on the SD card.
Mechanical End stop switch :
We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruptors, we use a mechanical switch. If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. If you’re worried about reliability, you can sleep well at night. The switches we use are rated for 1 million operations before failure. Since we only use the switches once per print, that means you’ll be able to do one million prints before having to replace the switch.
MK2B PCB Heatbed :
The LED and resistor are soldere, good compatibility, support 12V, 24V power.If you use 24V, this time the current is very large, MOS tube heat seriously, it is easy burne because of the high temperature.
In addition, also consider the adequacy of power supply, power up to 576W of power is very expensive, if power shortage may affect the normal operation of other equipment such as motor.
Also note that because of the wire is not enough thick and cause burning hot and soft.
Nema 17 4.2 kgcm Stepper Motor :
It is also a suitable motor for various robotics applications. This motor is the most preferred motor used by the rep rap community. A stepper motor can be a good choice whenever controlled movement is required. They can be used to advantage in applications where you need to control rotation angle, speed, position and synchronism. Because of the inherent advantages listed previously, stepper motors have found their place in many different applications. Some of these include printers, plotters, high end office equipment, hard disk drives, medical equipment, fax machines, automotive and many more.
J-HEAD V6 Hot End Extruder :
E3D v6 has kept their acerb thermal transition that gives the high quality printing performance users have come to expect from E3D hotends. A acerb thermal break gives better control over filament output so you get more immediate start and stops when extruding as well as retracts that are more effective in combatting ooze
