Then our search lead to an Arduino based 4-axis cutter developed by Marginally clever which used an arduino Mega2560 and the Ramps 1.4 CNC sheild. His page has codes for moving 4 independent axis and a Java based G-code sender application that could send the the G-code secquentially to the Arduino using the serial port. We tried this solution.

Now you made the base configuration for your RAMPS 1.4 board. If you transmitt this version to your board (klicking the button with the arrow to the right), then your display of your 3d printer should show the first signs of live. Ok, it's time to make the adjustments specific to your 3d printer. You might first check the setting for the amount.

The RAMPS 1.4 comes with 6 end stop connections (X Min, X Max, Y Min, Y Max, Z Min, Z Max). Rarely do you use all six. What you're really interested in is either the Max or Min. If you know one, you can limit movement based on it's location (0) via the software (if I can detect Min and know my bed is only 200mm wide then I can tell the software.

I am using two RAMPS boards, 1.4 and 1.6. I discovered that the V1Engineering dual endstop (and also default Marlin code) use pin 4 to PWM control the spindle speed. On my RAMPS boards that is the SECOND set of servo pins from the Reset button. But I also discovered that alone was not enough.

I've bought some stuff today in the hope to build a 4-axis CNC hot wire foam cutter. These are my parts: 1 x RAMPS 1.4 1 x MEGA 2560 R3 4 x A4988 driver 1 x USB kabel 4 x NEMA 17 The mechanical part is not my question. I know how to build the towers for the hot wire and I will control the hot wire separate from the CNC 4-axis electronics.

Hello all, Ive recently become interested in doing some cnc milling on my machine that uses ramps 1.4 electronics. everyone has sort of thrown things like mach3 and skeinforge at me, but im not sure where to start. as 3d printing you use the slicer to make the gcode and its very streamlined and hard to mess up or cause any damage to the machine. with milling though im not sure what to use to.

The H2 and H4 input to the laser driver support voltages between 3.3V and 36V. 12V from the RAMPS 1.4 will be fine to use and will turn the laser on. If you want power control, then use the PWM function. Most firmware for the RAMPS board have this built in with the M106 command. M106 S255 will be full power on.

When looking at the Ramps 1.4 board with the power-plugs facing left, the endstop-pins are located in the upper right corner as shown in the image. From left to right we have X-min, X-max, Y-min, Y-max, Z-min, Z-max. The top most pins are Signal pins, the middle pins are ground and the lower pins are 5v/Vcc.

Re: ramps 1.4 and external stepper driver. STEP and DIR are direct connections to output pins on the CPU. Your diagram indicates they're all opto-isolated, so I think you can probably connect them as you guessed with signal and ground.it will act like the PNP controller type in the diagram.
