This page attempts to make some sense, in general, of how all the pieces fit together to create a RepRap. However, if you want to skip all this stuff and get straight to getting your hands dirty then your best bet is to take a look at The incomplete RepRap beginner's guide and the build instructions category. In addition to those guides, you may also want to take a look at the links under the Models section below. RepRap Component Structure. That being said, to get a higher-level overview, we must start with discussing the different models of RepRaps, then go on to the four main components of a RepRap: The software toolchain. Models These days there are a growing number of many great and detailed build instructions for RepRaps! If you're steampunk or just like to get away without commercial kits, there are also RepStraps. Software Toolchain The software toolchain can be roughly broken down into 3 parts: CAD tools. CAD Tools Software Files There are very few interchangeable CAD file formats.

OFIS architects on Vimeo Upload User Stats Profile Images User Bio CAM Toolchains Java development THIS page is an extremely rough draft. You can help us improve it. (Someday this page will document many of the known-working systems. A few known-working systems are already documented at RepRap Options). This page has been flagged as containing duplicate material that Firmware/Alternative also attempts to cover.These pages should be merged such that both pages do not attempt to cover the duplicate topics.

Improved Analog & Digital Interface with Arduino « Analog inputs with Arduino and EMC | Newest entries | Generating HAL files from Eagle schematics » Building on my earlier work , I've now improved the interface between HAL and the Arduino board to have: 6 10-bit analog inputs 6 8-bit PWM "analog" outputs

Prusa Mendel Assembly Prusa Mendel Documentation Before assembling a Prusa Mendel, make sure you have all the parts necessary. For the bill of materials, see Prusa Mendel. ELM - DC Servomotor Controller This is an experiment on the closed loop DC servomotor control system (SMC). It will able to be used for practical use with/without some modifications. The closed loop servo mechanism requires real-time servo operations, such as position control, velocity control and torque control. It will be suitable for implementation to any embedded 32 bit RISC processors as a middleware. In this project, these operations are processed with only a cheap 8 bit microcontroller. Recently, most servo systems are using brushless motors called "AC servo motor" to reduce maintanance cost.

BIOS beep codes. I see many users to confused on BIOS beep codes, so ill create a new topic with them (i search the forum for a topic like this but i didn't find anything, but if this topic exists just delete mine.)

Nigel's PIC Tutorial Stepper Board Stepper Board This is the Stepper Board, it contains four transistor drivers for feeding a uni-polar stepper motor, such as those commonly found in old 5.25 inch floppy drives and printers. The transistors are fed via 470 ohm resistors, to limit the base current, and the eight diodes are there to absorb the back EMF (Electro Motive Force) from the stepper motor coils when they turn off - when you turn an inductor off, be it a motor or relay, it generates a high reverse voltage spike (which is how car ignition coils work) - this would be likely to damage the transistors, the diodes prevent it. The stepper motor itself consists of two centre-tapped windings, with the centre-taps connected to the positive supply rail, to make the motor move you need to activate the coils in a certain sequence, it then moves one step for each value in the sequence - a half-stepping mode is also available, which gives double the number of steps by using a slightly different sequence.

G-code This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The main target is additive fabrication using FFF/FDM processes. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications, too. There are a few different ways to prepare GCode for a printer. One is to use a slicer like Slic3r, Skeinforge or Cura. These programs take a CAD model, slice it into layers, and output the GCode required for each layer.

Make a solar-powered 24 hour greenhouse This cool project for a solar-powered 24 hour greenhouse comes from Instructables user and TreeHugger favorite, Joshua Zimmerman. Zimmerman has provided us with some great solar-powered projects before and you can check out even more at his site If you have some experience with DIY gadgets, you should be able to easily tackle this 24 hour greenhouse, which uses a solar panel to generate energy for providing a little extra light for house plants during the night. Included is also a 10-minute super easy version that uses a 2-liter plastic bottle and an old LED garden light that even beginners could handle. Zimmerman says:
