Hey All, just stumbled upon Gearotic the other day and am looking forward to using it more to generate some 3D printed clocks.  I've always been fascinate d with horology and have worked on a few clocks, but could only lust after clocks with some of the more exotic escapemen ts.  Brian Law's 3D printed clocks site (https://www.3dprinterclocks.com) was an eye opener for me on the possibili ty of designing my own clocks with some of these other escapemen ts, the grasshopp er and gravity escapemen ts specifica lly being of great interest to me.

Ken Kuo's SolidWork s models that he puts on YouTube (https://www.youtube.com/channel/UC2h07cGBpJs8bF3OkgtJICg) are a wealth of possible escapemen ts to try.  I wish I could take a stab at modeling them like he has, but $4k for a SolidWork s' license is just a bit too much for me.  Gearotic's simulatio n capabilit ies seem like the next best thing comparing other options at the moment.

Anyways, much to learn!  Looking forward to it.

Welcome the the group Dan.

   Nice site that one, he does nice escapemen ts..

Yell if and when you need a hand, or if the software confuses.

It's been a while since you've added any new escapemen t types, Art Smiley

Kirk:

  Smiley, yes it certainly has. Unfortuna tely Im scared to dig in to Gearotics
code base too deeply. It was written under VS2013 and XP, runs well under Win7, but
I fear to do too much in there anymore. Most of my developme nt is now
in making a backgroun d architect ure in Vexx that will hopefully allow me to do
things like escapemen ts in there. Im aiming toward a specific goal, but never
really know if Ill get there.  So much is changing in the CAD world its a moving target..

Same as it ever was...  I read articles that said the computer business relied on massive annual growth and if the change level went down that a good chunk of the business would self destruct.

I suspect you could rebuild with the latest Visual Studio after you figured out the latest option revisions, but then it probably would only work on the latest Windows 10 destructo rs version.  At least the current GM works on my latest windoze insider preview laptop, or at least did when I cut the unexpecte dly oval gear on the Maslow CNC (it's fault, not GM's) last fall.  Will revisit after the snow mountain melts, many new firmware releases since then.

Kirk:

 I find the problem mainly in the libraries used for things like a menubar, the old ones are hard to convert
to new standards, theres lots of weird interacti ons. I try not to use such things now for future compatabi lity
but gearotics interface is kinda strange in its interplay with dialogs. I may pull its code snips into vexx one day and make easier to use gear generator s.. be easier then to add things like escapemen ts..

Hi Art,
It sounds like I should give up waiting for a "club footed" escapemen t.  That's too bad a couple of these have been my most reliable escapemen ts - I guess I have to continue "arm stronging" them.

Hey All, just stumbled upon Gearotic the other day and am looking forward to using it more to generate some 3D printed clocks. 


I too stumbled upon Gearotic within the last week. I hope to use Glowforge, Shaper Origin and other older tools to make some tickers. I went through the PDF manual and watched Art's first two YouTube videos on Gearotic Thoughts, and then noodled around with some gears to export. I exported as DXF - finding them was the first trick. I'm an architect by day so opening them wasn't an issue, but they were huge files for a DXF seemingly because in one gear the entity count was 15,780. Every curve is made up of a bunch of tiny segments. I tried printing as a PDF and opening in Illustrat or to save as an SVG. The result is the same with thousands of bits that I need to join. Is there a check box for exporting as curves that I'm missing?

Also, there was documenta tion or something in the video that said the DXF export location could be set in Global settings, but I didn't see that anywhere.  All-in-all very cool program, but the export is a huge problem. Having been a user for all of two hours, I hope I'm missing something simple.

Hi Rick:

   In the global settings is a setting for the data folder you wish to use. By default its in the Gearotic Motion folder and labeled as GearData. That folder can reside anywhere though,
mine for example is on the desktop, I just created a folder of that name there. Use global settings to point your data folder to there. Your gears will show up in a subfolder by the name of the project name. The global settings are in the small gear icon, top left of the applicati ons menu bar.

   The DXF's from gearotic are large, mainly due to keeping the curves as accurate as
possible, gears have been made from these dxf's up to 4 foot in diameter, so I try
to keep errors down by not producing them as equivalen t curves.

  However, you can control them and put them out as curves or at least as simpler
dxf's by running Vexx after you put your gears on the project screen. Run Vexx and
it will have a menu called "Gearotic" in which you can "Get Gears" from Gearotic
as vector data, modify as you wish, then export in Vexx as DXF, or STL. The DXF's from
Vexx are supported by Fusion 360 as well as most DXF programs.

  Vexx has tools to convert line segment vector contours to curves as well, but take
note that creating a bezier form of a gear may not be as accurate as the line segment
 form. All depends on requireme nts in the end. Yell if you run into trouble, we're usually around..

Thanks Art. Figuring out what Vexx was took me a little noodling, but thanks to a forum search I got there. Add to that what you wrote about getting gears. It's actually quite interesti ng to be able to offset, add slots, array, etc. of the gears. As far as exporting as the lines from Vexx as a DXF, it doesn't work, (For me). AutoCAD says "Missing Default entry 0 in SymbolTab le:LAYER
Invalid or incomplet e DXF input -- drawing discarded ."

BUT! I don't care - because.. . I can export to an SVG from Vexx. This is what I need anyway and thought I needed the DXF as a stepping stone. I see what you're saying about the Bezier curves and segments. It messes with the joints. It's a much cleaner curve with all the little bits. I'll see if my laser or Origin care. I may just be overthink ing this.

Hi Rick:

  In the option settings for vexx there is also a setting for DXF output type,
you may have better luck with the secondary option. If you dont see that option
make sure your using the developme nt version, it has a dual type dxf output setting.

Glad its working out.. Smiley
