The environment dictionary, env — Fabric 1.5.1 documentation A simple but integral aspect of Fabric is what is known as the “environment”: a Python dictionary subclass, which is used as a combination settings registry and shared inter-task data namespace. The environment dict is currently implemented as a global singleton, fabric.state.env, and is included in fabric.api for convenience. Keys in env are sometimes referred to as “env variables”. Below is a list of all predefined (or defined by Fabric itself during execution) environment variables. Note that many of these may be set via fab‘s command-line switches – see fab options and arguments for details. abort_exception Default: None Fabric normally handles aborting by printing an error message to stderr and calling sys.exit(1). Give it a callable which takes a string (the error message that would have been printed) and returns an exception instance. abort_on_prompts Default: False all_hosts Default: [] Set by fab to the full host list for the currently executing command. always_use_pty Default: True cwd
winder/Universal-G-Code-Sender: A Java based GRBL compatible cross-platform G-Code sender. Repository Structure and Python This opinionated guide was written for my best-practices guide, The Hitchhiker’s Guide to Python. It is based on the recommendations of the Distribute project, personal experience, and good intentions. It’s Important. Just as Code Style, API Design, and Automation are essential for a healthy development cycle, Repository structure is a crucial part of your project’s architecture. When a potential user or contributor lands on your repository’s page, they see a few things: Project NameProject DescriptionBunch O’ Files Only when they scroll below the fold will the user see your project’s README. If your repo is a massive dump of files or a nested mess of directories, they might look elsewhere before even reading your beautiful documentation. Dress for the job you want, not the job you have. Of course, first impressions aren’t everything. Sample Repository tl;dr: This is what I recommend. This repository is available on GitHub. Let’s get into some specifics. The Actual Module Location . . . License . How?
Firmware Configuration Tool 0.92.8 Path planning makes your printer moves more smooth. Have a look at the above picture. It shows a print of three lines. Move Cache Size (default 16) That is the size of the buffer for currently processed segment and following moves. Minimum time per move when cache is below (default 10) The path planner has some tricks to prevent empty buffers. Assumed ticks per move computation time (default 250000) The minimum time in processor ticks, each segment must need if the cache is low.
Django at a glance Because Django was developed in a fast-paced newsroom environment, it was designed to make common Web-development tasks fast and easy. Here’s an informal overview of how to write a database-driven Web app with Django. The goal of this document is to give you enough technical specifics to understand how Django works, but this isn’t intended to be a tutorial or reference – but we’ve got both! Design your model Although you can use Django without a database, it comes with an object-relational mapper in which you describe your database layout in Python code. The data-model syntax offers many rich ways of representing your models – so far, it’s been solving two years’ worth of database-schema problems. Install it Next, run the Django command-line utility to create the database tables automatically: The syncdb command looks at all your available models and creates tables in your database for whichever tables don’t already exist.

3D Printing Apps - GCodePrintr, GCodeSimulator, GCodeInfo & more How to Get Started with PAnt Follow these steps to to get started with PAnt: Download Jython. Note that as of right now Jython 2.5 is somewhat slower to initialize than 2.2. You only need 2.5 if you want to be able to use decorators to create Ant targets. Unzip jython distribution. Note: you need jython.jar and all files under Lib. Download PAnt. Now the prep work is done and you can begin developing your build logic in python. That's it, the rest of it is simply writing your build logic in python using Ant tasks as documented here.
CraftWare Overview CraftWare is a FREE, fast, easy-to-use slicer software that converts your digital 3D object into a .gcode toolpath format understood by most 3D printers. CraftWare primarily works as a slicer for solid 3D digital objects, but it is also an excellent tool for many other tasks. You can interactively manage your prints, thus reducing build time and finding the optimal build supports. CraftWare utilizes dual channel communication for real time interaction between the software and the printer -just another great tweaking option. Our slicing algorithm effectively supplies the best possible toolpath for your CraftBot, providing the utmost quality as soon as possible. Strengths Open multiple .stl, .obj files and arrange them on the build platform. Modeling CraftWare is not a 3D design program. Help us test it out CraftWare is currently in the Beta stage, so feel free to download it and let us know what you think!
Python Multithreaded Programming Running several threads is similar to running several different programs concurrently, but with the following benefits − Multiple threads within a process share the same data space with the main thread and can therefore share information or communicate with each other more easily than if they were separate processes.Threads sometimes called light-weight processes and they do not require much memory overhead; they care cheaper than processes. A thread has a beginning, an execution sequence, and a conclusion. It can be pre-empted (interrupted)It can temporarily be put on hold (also known as sleeping) while other threads are running - this is called yielding. Starting a New Thread To spawn another thread, you need to call following method available in thread module: thread.start_new_thread ( function, args[, kwargs] ) This method call enables a fast and efficient way to create new threads in both Linux and Windows. Example #! When the above code is executed, it produces the following result − #! #!
eclsnowman/HercuLien: HercuLien - Large Format, Dual Extrusion, Bowden/Direct Drive Modular, 3D Printer. Inspired by many... Created by me. Django REST framework - APIs made easy Online 3D Converter Convert 3D models between file formats (i.e. FBX to OBJ or OBJ to STL for 3D printing, DAE to JSON for use with WebGL, ..). Supported input file formats include 3DS, FBX, Blender, OBJ, DXF, LWO, STL, PLY and more than 25 others. Output formats include Collada, 3DS, X, OBJ, PLY, STL (Text and Binary), JSON (Assimp2Json) and more. Tweet Some tips on conversions that this tool does not support (and frankly never will): Press Start to begin the conversion. Please wait while your files are being converted.
