Dynomotion wiki
Welcome to our wiki where you can find and share knowledge on Dynomotion's systems. To begin adding information to this wiki, simply create an account, verify your email, and start editing (click pencil icon). To make editing pages easier for everyone, we have installed a visual editor by default. This visual editor allows you to edit a wiki page much like you would a standard word processing document. For the seasoned wiki editors, standard MediaWiki editing may also be used.
Warning: Use at your own risk. Information is for example purposes only and may contain errors. It is up to the User to verify the information is correct and is safe to use. In no case will any contributor or Dynomotion be liable for incorrect information. Dynomotion reserves the right to modify or delete any contributions.

Editing and Creating Wiki Pages
Unintuitively, you first create a link to the page you want to make before you can make the page. To make a new page: while editing, right-click where you want your link to be, insert a link with a descriptive title and link text, save the page, click on the link you created, then click on "Empty Page" to begin editing your new page.
Here are a few other quick tips:
- You can insert links or images by Right-Clicking with the mouse on the line where you want the link or image to appear.
- For Spell Correction you can use Ctrl-Right-Click.
- To insert a YouTube Video use an EmbedVideo command such as {{#ev:youtube|xxxxx}} with xxxxx changed to the Video ID.
- Choose a descriptive page name and link text when creating a new page: e.g. Not "My Machine", but rather "Brand X Three Axis Milling Machine Retrofit"
- Create pages in an organized manner: Describe what the page is about, create clear sections that flow

Installation Topics
- Latest Production Release: Full release download page
- Latest Test Release: Released 08/29/2015: KMotion.exe V4.33q, See the release notes for this test version here: V4.33q release notes (pdf)
- How to install KMotion.exe and KMotionCNC
- How to update KFLOP Firmware - whenever a new version of software is installed, the firmware within KFLOP must be updated to match the new version
KMotion.exe Executive Software Topics
KMotion.exe is the main program that is used to configure settings in KFLOP, initialize axes, and to write C programs to configure and setup KFLOP to control your system. In this program you can plot step response, test movement, view Bode plots, monitor I/O, set filter parameters, and generally set the pertinent parameters.

KMotionCNC Software Topics
KMotionCNC is Dynomotion's CNC program used as a graphical user interface to your KFLOP-enabled machine tool. KMotionCNC has all of the basic functionality you need to run a machine of up to 6 axes, in addition to spindle control.

Customize KMotionCNC
KMotionCNC is written as a Windows C++ MFC (Microsoft Foundation Classes) program developed in Visual Studio. Source code is provided and may be customized using Visual Studio. MFC Support is a requirement.
- General Information
- Compiling KMotionCNC
- The KMotionCNC's Visual Studio Project Solution (\PC VC Programs\KMotionCNC\KMotionCNC.sln) is currently written for Visual Studio 2008 Standard. This version can be used for the simplest compatibility. Projects can be upgraded to newer version of VS with minimal effort. Including Microsoft's Free Visual Studio 2013 Community. More info on PC Example Applications.

PC Example Applications
A number of PC Applications using the KMotion Libraries are available in the Software download. Visual Studio should be used to modify/compile the applications.
Currently the projects are compatible with VS 2008 Standard but later Versions can upgrade the projects and can be used including the free Microsoft Version of VS 2013 Community. In some cases MFC capability needs to be added as a separate download.
KFLOP C Programs
C Programs provide a powerful and flexible capability to perform almost any sequence of operations within KFLOP. In most cases after you have tested and tuned all your hardware using the KMotion.exe setup program all the settings and initialization steps required for your system can be placed into an Initialization C Program so that your system can be fully initialized simply by executing the Initialization program.

Wiring Topics
Place links to pages on wiring inputs and outputs specific to your experiences and projects. Be descriptive with page titles and links.
MPG Wiring and Interface
MPGs (Manual Pulse Generators) should be connected directly to KFLOP for guaranteed real-time response (not USB based or connected to the PC). MPGs are handled by a C Program that monitors the MPG and creates motion based on the MPG Encoder changes and switch selections for axis, speed, and so forth. See the MPG C Program Examples. Here is a Discussion with other links.

Axes Servo Tuning and Trajectory Planner
Velocity, Acceleration, and Jerk
The KMotionCNC parameters are used for 2nd order (infinite Jerk) coordinated motion paths. These are GCode G1,G2,G3 continuous paths. The units are in Inches (or in some cases degrees).
Tests to find optimal settings for both types of moves should be made using the Step Response Screen. The Step Response Screen always performs 3rd order motion but 2nd order motion can be simulated by temporarily setting the Jerk to a huge value (1000X the acceleration value). In general reducing the Jerk value will result in longer times to perform motions, but often the improved smoothness will permit higher maximum accelerations and velocities to be used resulting in overall shorter motion times.
Make sure when testing the size of move is long enough for full acceleration and velocity are achieved. As a common mistake is to have Acceleration or Velocity Settings set to too high for your system but when testing a short move there is no indication of a problem. The plot mode of Velocity Output vs Time can be helpful to verify full Velocity is being achieved.
