Mach4 General Discussion / GSim Mach4 Material Removal Simulator
« on: January 24, 2015, 04:01:11 PM »
Hi All:

    Ive decided to release a Mach4 plugin thats not a motion driver, but one that will work on any Windows
install of Mach4. GSim is a simulation that shows the material removal and displays some other statistics that I find
helpfull about a job I may be about to run. It can be used to experiement to see the effects of various tools on
more artisitc carvings, and is simply a good way to see if your really about to cut the right thing. :)

 A video is here

  and the plugin will be posted here as soon as the next update of Mach4 is out ( 2192). Should you find bugs
or wish to see features in this beta release, please drop comments here. Hopefully it works out well, only I have run it so far.

Hello Everyone:

   In this thread I will post any information or bugs with the Darwin Printer Port driver for Mach4.

A video for configuration Darwin in Mach4 can be seen here for those testing the driver.

GearoticMotion Preliminary testing / Gearotica testing
« on: July 28, 2010, 10:21:28 AM »
Hi Guys:

NOTE: [ Test ended. Thanks to the 20 people who downloaded, please post your experiences. ]

   Gearotic motion could use a few testers to play with it for a few days. Id like to know if the program exhibits technical difficulties on various cpu types.

Some things work, some dont.  . The program can save projects you make, and if you send me the project file I can send you dxf ( 3d and 2d) of your
projects as a reward for testing this for me. This test will likely last only a little while so I can see if there are size/openGL issues and such.

If you do something you like, and woudl lilke to actually cut it, just send me a project file you save and Ill make the outputs for you, the output section is not yet
in the program and is a separate utility at the moment.

Here is a (bad) description to get started...

To use:
 Youll be presented with the main screen. Hit the "Involute" button or select the Involute tab. Youll see two gears on the screen.
Hit the "Add Master to Project" button. Press OK on the resultant dialog without changing anything.The screen will flick to the project screen and about 2 seconds later a gear will appear. This is the master driving gear. Now select the involute page again. Select again the "Add Master to Project".
In the resulting dialog, check the "4-bar linkage" checkbox. The screen will flick to the project screen again and the Master will be lit up in blue. Click it with the mouse and your new gear will rotate around the master till you click again. Then, moving the mouse will move the linkage around. Click when your happy
with position. The gear is now set and linked.  Press Simulate to run it. Using the mouse with ctrl or shift key pressed will zoom and pan.
   In general, when placing a gear, you can click a screen gear to select the one you intend to place to, OR select a gear from the project list by hovering over it when in placement mode. Clicking on a gear will select it as the gear your going to mesh to. Once clicked on the selecting gear, it will either place it,
OR a message will appear in the top coordinate line to explain why it wont.
  Some notes. ...
  To use 4-bar linkage the gear you link to must be smaller or equal to be linked. You can link to a larger gear, but if you do you should ensure that gear does not rotate 360 degrees as the master does. If you violate the rules like making a link gear turn too much thus being in violation of the rules
of 4-bar linkages, the gear will blank out when rotating beyond its capability. If this happens, delete the gear and replace it with a larger one.
To delete a gear, right click it in the Project tree and select "Delete train..", this will delete any gear and all gears attached directly to it.
To Turn a gear.. ( Like rotating a gear on a shaft with a setscrew), select a gear on a shaft by clicking it from the project list. Then use the CCW and CW
buttons to change its primary orientation on the shaft. This is usually only desired with ellipticals on a shaft with a linkage gear to set the "sweet spot" of rotation for the elliptical. ( Youll get what I mean as you play.. ) , thi sis th eonly way to rotate an individual gear in a larger train of gears.
   Some gear types do not yet do output, or place on the project screen. ( Planetary configurations do not yet work for example. )
  Save or load project with the buttons on the upper left screen. A test project is included so feel free to start by simply loading that project. There is
not yet a progress bar so be patient while large projects load.

Thanks, Enjoy and PLEASE post your comments..


Show"N"Tell ( What you have made with your CNC machine.) / My Clock
« on: November 10, 2009, 09:57:39 AM »
Hi Guys:

  I figured someone might like to see my clock.. soemthing I decided to try and ended up spending 3 weeks obsessing on. :-)


Hello All:

   This board, when open to public use, will be used to allow members to discuss , test , and provide feedback on the "Tempest" planning system.
Snapshots, explainations, and test evaluations will be topics of this group to allow the development of the planner to proceed into testing phases
as the theoretical models and algorithms are being completed.

  The Tempest planner is a proposal for the next generation of planning module. Its code is nearing completion and testing phases and builds
will be posted here for evaluation. Its specifications are as follows.

 Tempest is a 9 axis, 5th order planner with optimised segment blending and velocity control. It uses 6th order blending between lines of any length,
and 3rd order blending between arc/line junctions.  Orientation axis include a,b,c and u,v,w. In its end form it will allow task space or joint space control
and will include kinematic control extensions for a wide variety of configuration capabilities. It's planning order while set only by a jerk limitation factor, will
control both Jerk and snap through most of its trajectory with the exceptions of blends involving arc's. All blends ( or CV moves ) are set by the user
as a spherical tolerance where-in the blend will occur in an isoscelese triangle of the entrace and exit to the user defined sphere. This means a setting of
CV to 10mm will result in blending arcs of no more than 10mm at corners. Speeds are limited by the calculated acceleration constants involved with arc's
of various radii or in blends of various polynomial lengths. Arc involved blends are tangental matched for c2 continuity, joined with Hermite curves , while
line/line blends are joined with 6th order polynomial additions of 1st order linear equations.

  It is hoped the Tempest model will eliminate the problems involved in the Quantum experimental SCurve generator, and Tempest will reach speeds
orders of magnitudes higher than Quantum in small segement control and concatenation. Algorithmic modeling is near completion and this board will
be opened as soon as the first preliminary test builds are available to achive motion for user feedback testing. I will use this board for posting notes and
explainations of various features and options as well as to document its usage and any limitatiosn found in testing. This is a highly experimental module,
and while the math and graphing functions show high promise, only true machine testing and time evaluations of CPU usage in the calculation of the
real time motion waypoints will tell us if this may yet be used by cpu's of today or if more optimisation is required to the central calculation routines.

  So if your reading this, please feel free to download any test programs, and report any findings or opinions you may have. hopefully "Tempest" will
be the start of the next generation of CNC control. In theory, almost any machien will benifit from the incredibly smoothed motion and acceleration
control it offers.

Good luck, Thank you for testing.


LazyTurn / LazyTurn
« on: February 13, 2008, 12:39:09 PM »
Hi Guys:

  As you probably know, I tend to futz about form one project to another. But Turning is something I had intended to do for
some time. SO while I can't promise this will come to full development, I am working on a replacement for the turning mode in
LazyCam. When complete, Turning will be removed from LazyCam and will be replaced by this program.
  Turning is pretty hard to do for most people. Im really looking for an easy way to make my own profiles. This program is a DXF
or other vector file loader, which then will assist is creating a turning Gcode. It is planned to do boring, facing, roughing, grooving
and finishing from an imported profile. Presently, all thats done is the input and display sections. But Id like to have any input from
Turn people on what exactly makes a program easy to use in terms of generating a Turn profile.

  This program is a raw begining. Dont expect fancy menu's and such till I get there, each step along the way I am analysing just how
easy it is to use and create profiles. This program will , in the end, also allow for profiles to be drawn. At the moment, all you can do is load
pre-existing dxf's, hpgls, or other vector format data. In your mach3 folder under examples, is a "ainsideprofile.dxf" and an "aoutsideprofile.dxf"
which you can use to test this program, and subsequent releases.

  Any comments are welcome as to ease of use, or ideas you may have for the graphical display of whats going on.

 As I said, this is raw, it will allow loading, display of the profile, stock, and measurements of various things in the loaded profile.

The next post wil show a screnshot, have a download link for the program as it stands, and a short description of function.
We'll go from there. This is being done because Ive always felt a bit bad about not supporting lathe users to the levels I had always hoped,
and also as an experiment as just how to make LazyTruning, truly lazy. From the users perspective at any rate.
