How does the home position work on a Prusa i3 RepRap Printer?

By what process does the Prusa i3 determine it's home position? I have a feeling that it works like this, but I'm not entirely sure about it: If none of the end stops are activated; assume you are somewhere between Max-X, Max-Y, Max-Z and the…

What's the advantage of two z motors?

Some RepRap models use only a single motor for the Z axis, others use two. For example, there is the 3drag that has only one motor and a smooth rod on the other side. There are modifications that add a threaded rod on the other side that is…

3D printer stepper motors only going one direction and skipping in the other

I have built a couple of 3d printers now and I'm having a little trouble with one I'm currently on. I frankensteined this one with two of my other printers that I had built. I took the Arduino mega and ramps 1.4 out of the older one and wired it up…

Is the weather a problem for MDF frames?

I've acquired all the parts to build a Reprap Prusa i3 rework, the only missing part is the frame. I'm in doubt between a MDF cut (cheaper) or acrylic (more expensive), of course a cheaper one is my preferred option until I see any disadvantage on…

Connector Suggestion for Extruder and Heatbed

On my Reprap-like 3D printer, I routed all the wires to a spot near the base; for the motors, endstops, thermistors, etc, I plugged them all into a DB25 breakout board, and that's working great. For my Extruder (12v), and my heat bed (16v), I'm…

Using an Arduino Mega with burnt voltage regulator

Due to a not-given compatibility with Makerbot mechanical endstop wiring (and carelessness on my side) I ended up burning the voltage regulator on my Arduino Mega 2560. Now, powering the Arduino separately from a USB power supply, I can operate the…
