Ramps PLus2 is suitable for all kinds of 3D printers, such as UM, Reprap, Detla and Kossel, CoreXY and HBot, SCARA and so on.
Four layers of exquisite workmanship, from millions of automatic patch production line. Functional characteristics: A) fully compatible with the IO of the Ramps 1.4, the name is very similar to the name, on the market, the Ramps 1.4 less than 20 yuan of Sheild board, in the field of 3D printers have an absolute position, a large number of Marlin and Repetier code can be used free of charge. When configuring a single extrusion, two boards can wear a pair of pants, and nothing can be changed to work. Even the LCD interface, the two 10P Niu seats are all compatible with Ramps1.4 Reprap LCD12864 (note that MKS LCD12864 and LCD2004 are incompatible because they are incompatible with Reprap). B) when configuring double extrusion, Ramps1.4 has a drawback, which is to take Fan as a second extruder, so that when double extruding, there is no fan to control, Ramps Plus 2 has been improved, D7 is used as a second extrusion heating, and the fan is still using D9, so that there can be a double extruder heating, and there is also one. A controlled fan (Pin9). C) the most important thing is that Ramps PLus2 can be expanded to three extrusion. Compared with more than five hundred yuan for the three extruded motherboard on the market, the price of Ramps Plus2 to three is only more than 200 yuan, and it supports a variety of LCD, touch screens, etc. D) added a Laser port, Laser port output 5V or 12V, two selected one. E) add a LED lamp that can be controlled by instruction. F) retained the automatic shutdown interface PS-ON. G) retained the I2C interface. H) retained a set of steering gear interfaces. I) reserved two sets of 12/24V xh2.54 terminals, which can be connected to fixed cooling fans, such as extrusion heat dissipation, power dissipation and so on. J) use the XH2.54 terminal as the main interface. K) the automatic leveling function can be used L) is compatible with Ramps1.4’s LCD12864 and LCD2004 interface. As long as it is Reprap standard screen, the firmware on the brush will be lit up. M) the power chip is switched to 2596, which greatly reduces the calorific value and does not need to heat the radiator without heavy load.
N) the rudder power supply and the laser power supply 5V part L5V can be connected and can be connected, it is decided by the jump line next to the PS-ON, the jumper cap is short connected with VCC and L5V, it is the internal connection, and from 2596 for 5V, and after the direct common GND, the access L5V is used by the external 5V to supply the rudder and the laser, so the design is because of the work of the rudder and the laser. The rate is too large, causing too much fluctuation to the chip power supply.
Matters needing attention： A, brush firmware when, to pick up the 12V to be able to, because our USB chip is transferred through the 12V through the 5V to power, not to take USB power supply, not like Arduino 2560, the same as the power supply in parallel, the circuit causes a lot of unstable influence, professional control board, should be used with 12V, so stable It’s sure to be reliable. B, the power to pay attention not to reverse, pay attention to watch the power terminal – and 12/24V, after the reverse, the circuit can only be short time protection for 1 second, and then the component will be burned. After the power is connected, a red LED lamp will appear behind the power outlet. Firmware downloading: please consult customer service!
