3mm with a 0.5mm Nozzle is great. But when you get down to 0.35mm Nozzle, people seem to get a lot more jamming problems when using 3mm. Understandable, as you are trying to force a wider diameter filament through a smaller hole. But in order to push out the same volume of plastic, the 1.75mm extruder needs to turn a lot faster, depending on whether your extruder is geared or not, and the limitby ShadowRam - General
End Stops are SOURCING inputs. Meaning the mechanical switch should be wired to S (Signal) and G (Ground)by ShadowRam - Reprappers
Fold the belt over and use another clamp? Stack three or more clamps as you interweave the belt through them?by ShadowRam - General
Thermistor is a voltage sensor. Very susceptible to noise from high-power sources. (like a heating resistor) This is the mostly likely reason you are seeing the temperature jump around.by ShadowRam - Controllers
Maybe, CNC requires strength, meaning you will need some beefy Steppers. RAMPS by default uses <2A Steppers. The reason I say maybe, is because if you go with screws instead of belts, you may get the torque you need for CNC milling.by ShadowRam - General

Connect to the Arduino via the USB without the 12V and see if you can connect to it. Make sure you pay attention to what COM port the Arduino Software is attempting to communicate on, and that you have the Mega 2560 selected.by ShadowRam - Reprappers
Is anything else have COM6 open?by ShadowRam - Reprappers
Yup, more cooling is needed on the layers before the next layer is printed.by ShadowRam - Reprappers
Quotecould not open port COM6 The problem is listed right there. Is your mega 2560 really on COM6?by ShadowRam - Reprappers

How's your Z-Steps/mm? If the first couple layers are ok, and they the layer adhesion gets worse and worse, it sounds like a Z-Step problem.by ShadowRam - Reprappers
If you can move the axis with the power and software on, than the motors are either, Not getting power or Not enabled.by ShadowRam - Reprappers
The wiring on the Stepper could be incorrect. Switch pin 1 and 2 or 3 and 4.by ShadowRam - Reprappers
Someone should respond to this 3D Printed gun mess with a 3D Printed bulletproof vest.by ShadowRam - General
Have you checked your power supply? (Check it with a meter) Are the motors getting any power at all? With your original software and power on, can you move the axis by hand? (You shouldn't be able to)by ShadowRam - Reprappers
You could try the RAMPS 1.4 test code. It just outputs to all motors to move back and forth a small bit and flash some LEDs. Not sure if it will work on the RAMBO, but since the Rambo says it accepts RAMPS firmware, it should work.by ShadowRam - Reprappers

Not a bad idea, Not to hard to to wire up either. But I'd be worried that a bit of extrusion stuck to the nozzle would prevent the tip from making electrical contact, and drive the head into the copper plate.by ShadowRam - General

Stepping AND Direction pins need to be closely timed. If the Arduino spits out a direction high and stepping signals, and there's a delay of the direction pin, there will be a few counts by the Arduino assumed in the wrong direction. Seriously, you already saved yourself stepper motors and stepper drivers, just get a proper Arduino with more IO. The few bucks you spend on it will save you so mby ShadowRam - Controllers

Guys, seriously don't bother with the Pi, It's I/O is laughable. If you want something to replace the Arduino and be the computer at the same time look at a lot of the Pi's competitors. BeagleBone would be a good example. http://beagleboard.org/Products/BeagleBone%20Blackby ShadowRam - Controllers
I'm not talking about permanent flexing. The mass and movement of your system will cause major inaccuracies at your hotend tip. For a frame that larger you should be using Structure Framing So the fact you can swap out parts of the frame is irrelevant. The reason full step isn't used on stepper motors is because they create a lot of vibration. Since your frame isn't very rigid, that vibratioby ShadowRam - Reprappers
