Join us on GearHead forum to see what we've been up to and what were presently working on. (email support for membership). Also beware of some Antivirus programs triggering warnings with this site or while installing Gearotic software, we urge that you contact your antivirus supplier and relate the issue to them. however we have found that problem is generated from the letters "otic" in Gearotic giving false warning.

Non Circular Gears
Cage Gears


 Gearotic is a CAD/CAM 3D software package aimed to assist with your geared mechanical creations. It was primarily designed as a gear template generator, but developed into a utility package we hope you'll find useful.   Gearotic will generate gears individually or combine them to create a moving gear train. Software allows you to simulate, animate,  create toolpaths for cnc mode or iexport as 3D models. Inside, you'll find a variety of gear types such as spur, cage, non circular, planetary gears, sprocket, timing pulley, bevel, root blower, geneva, racks, escapements and more. Our spur gears may be done in a helical or bevel form which can then be outputed in Straight, Helix or Zerol formats. These outputs include STL files for 3D printing, 2D DXF format for most Cad programs, 1:1 scale printouts for woodworking patterns or G-Code for CNC users.

Gearotic can provide statistical data about the gears and it also comes with a gear train calculator. Everything about Gearotic can be utilized as an easy to use, drag and drop designer front end that will simplify many processes to create your masterpiece. We do hope you enjoy using it and welcome your input on our support forum. 
 Our licensing model is simple:  once licensed, always licensed.  Upgrades are free and development is usually based on user suggestions. We feel Gearotic is more of an interest group and therefore we welcome you to join us on GearHead forum.  We ask that any support questions be done on Gear Head Forum,  however should you have any access issues, please contact us at or via link below. You need not be licensed to use Gearotic or to join our forum, we welcome everyone to the discussions. Project samples may be downloaded to build your own, these are located below inside the projects gallery by clicking "more"

Have fun..

 Please note that once software is downloaded and installed, it becomes our DEMO version, however when a license gets installed, the software automatically reverts to a fully licensed version without any special software required. Licenses are liftime activated and will stay installed during any future upgrades.
Gearotic offers two version to choose from when downloading.The first is called Gearotic3 which is our latest tested and stable version, while the other is called Gearotic3 Dev. Version. Both are identical with the exception of Gearotic3 Dev Version includes the newest bells and whitsles we have to offer and currently working on. At this point of Gearotic's life, my suggestion is to download our Dev. Version, however if you feel the tested and stable version is right for you, then go for it.

About Us

Gearotic was begun in 2010, by Art Fenerty and Bob Landry.  The program is an evolving work by Art Fenerty, the original author of the Mach3 controller program. Its content grows with whatever Art writes as he continues to explore various utilities in the world of Motion Control for hobbiests.  Our passion towards CNC machines as a  hobby and our own needs for machine utilities continues to drive us forward.. Our current project focuses on a motion controller to add to Gearotics capabilities.
