BobCAD-CAM is a developer of CAD/CAM software for the CNC metalworking and manufacturing industry. Based in Clearwater, FL, BobCAD-CAM has a staff of approximately 85 employees. Since opening in 1985 they've developed a reputation in the industry as having one of the most powerful and affordable CAD-CAM software available.
History[edit]
BobCAD-CAM was created by Bob Twaalfhoven, who graduate from MIT in 1978 with an engineering degree. Twaalfhoven created the software as a means of bringing CAD/CAM technology to the personal computer. Before then, CAD/CAM software was not generally accessible to the masses.[1][2]
Twaalfhoven originally sold his BobCAD-CAM software from the trunk of his car. He sold to manufacturing shops that wanted to automate their programming process but couldn't afford the massive price tag that accompanied traditional CAD/CAM Software in the mid-80's. Twaalfhoven opened his first office in San Jose, California in order to service the local manufacturing market. In the early 90's, BobCAD-CAM expanded to the East Coast where the company's second office opened in Clearwater, Florida.
The software was continually developed throughout the 1990s, adding 2.5 axis milling toolpath features, 3 Axis Planar machine toolpath capabilities for solid models and CNC lathe programming capabilities. This proved to be a wise development move as machining STL models became more popular in the CAD/CAM field. In early 2002 the most significant developments to the software were made by adding Design Surface & Solid Modeling technology, releasing the first Artistic CNC software add-on as well as introducing the first ever training video products for customers to learn CAD/CAM from the comfort of their office. The San Jose location was closed due to expansion of the Florida office; one office was now capable of servicing the global markets easily. In 2007 with the organizational structure of BobCAD-CAM in excellent shape Twaalfhoven began primarily focusing on the development of his CAD/CAM software and rebuilding the product from the ground up. This led to the release of the Version 22 CAD/CAM software, the addition of Lathe, Nesting & Sheet Optimizing and a joint venture with Predator software to offer high level editing and simulation to his customers. Between 2007 and 2014 BobCAD-CAM software technology has taken the largest strides in its company history in the development and implementation of CNC machining technology. The company became a SolidWorks Gold Partner [3] with the release of the BobCAM for SolidWorks CAM add-on for SolidWorks users to be able to program their parts right inside of their design product, saving them time and increasing the workflow efficiency for SolidWorks customers. Recently releasing CAD/CAM software programming technology for 4 and full 5 Axis CNC milling hosting the first ever High Speed Adaptive Roughing strategy for multi-axis CNC milling ever.
CAD/CAM Modules[edit]
It should not be assumed that all features on any given model of machine are supported by BobCAD. It is the users responsibility to determine, prior to sale, if particular features of a given machine will be used by BobCAD, and what additional effort may be required to do so. For example, it is possible to draw a turned part with tapped holes situated perpendicular to the main axis, however; what is meant by 'supported' is subject to interpretation. While it may be possible to make some machine functions operable with some effort, such as live tooling on a lathe the degree of difficulty varies, and technically, live tooling support for lathe is not provided. Industrial robots can be used for non-conventional milling for example.[4] BobCAD-CAM software is modular. Meaning that a CNC business can implement a core 2 & 3 axis milling software and 'add-on' to it as the business grows and needs higher levels of machining tool path capabilities. The 3 Axis CNC Software has a Standard and Professional version. There are also Standard and PRO versions for 4 Axis CNC Milling as well as the 5 Axis CNC Milling CAD/CAM. The 2013 Multi-axis CAD/CAM Software offers the first High-Speed Adaptive Roughing tool path strategy in the world for simultaneous 5 Axis CNC Milling. SWARF Milling along with 7 Surface-Based cutting toolpath machining strategies have also been developed into the Multi-axis CAD/CAM Software. The latest release of the CAD-CAM modules uses CAM Wizards for each machining strategy which is a planned series of dialog pages that pertain directly to the machining strategy that the user selects. Recently Dynamic Machining Strategies™ were added. DMS™ functionality requires the user to use a single or multiple machining operations for a CAD Feature that was selected in the process. This basically allows multiple machining operations to be used based on a selected CAD feature. CNC Software modules are available for:
- Mill Turn
- Art (Raster-to-vector)
- Nesting
- Machine Simulation and Predator CNC Edit
BobCAD-CAM also offers 2 other unique products for the Design & CNC machining world. The DXF ClipART series with over 6000 individual DXF files and the Machinist Toolbox software calculator.
Compatibility[edit]
BobCAD-CAM CNC Software is compatible with the following file formats:
- .DWG (AutoCAD)
- .SLDPRT (SolidWorks)
- .3DM (RhinoCAD)
- .X_T and .X_B (Parasolid)

Frequently Asked Questions
Open tabWhat operating systems can the E4 CNC router use?
The E4 comes with an Arduino based microprocessor using grbl that is connected thru a communications port thru a USB connection. We recommend the Universal Gcode Sender Platform Version which is a Java-based software that will run on Windows, OSX, Linux, and Raspberry Pi.
Can the E4 be run from a laptop? If so what kind of port is needed on the laptop?
Yes, you can use a laptop as long as you have a free USB port. The E3 CNC router uses GRBL firmware on the microcontroller. The microcontroller uses a USB to connect to the computer. Open source software such as UGS - Universal G-code Sender can be used with GRBL to operate the machine. Both GRBL and UGS have good documentation on the internet. The assembly manual can be downloaded and reviewed here.
What bits, or bit sets, on Amazon would you recommend for this?
The E4 CNC router DeWalt spindle comes with a 1/8' and 1/4' collets. Straight, vee and rounded bits will all work. They need to have a 1/4' or 1/8' shaft size. Search Amazon for “1/8' in router bits” or “1/4' router bits” and select the bits for the material you plan to use. Small end mills will also work.
What software will I need to buy to run the E4?
There are several choices of software. Most of them are open source and are free. The one I am currently using is the Universal G-code Sender (UGS). The firmware loaded on the microprocessor is also open source and is named grbl. There is lots of information on the internet about grbl I suggest using the search terms “Using grbl.”
The E4 CNC router, is like most CNC machines, as it uses g-code files. The g-code files are text files that can be computer generated or written by hand. There are several open sourced software packages that generate g-code.
You will need a computer with a free USB. Once you download the software, discussed above, to generate and interpret the g-code, you will be ready to create your projects with the E3 CNC Engraver.
How thick of wood can it cut through?
The E4 CNC router gantry height from the table is 3.3'. The maximum height from the bottom of the DeWalt collet from the table is 4.5'. Without a tool change, you would be able to cut 1.2' into a 3.3' thick stock or cut all the way thru a 2.25' (or less) thick stock. With tool changes, you would be able to cut thru a 3.3' thick stock.
Calculations for the answer.
4.5' -3.3' = 1.2' bit available to cut
4.5' = 2.25' of bit + 2.25' thick of stock
Can you make signs longer than 24' in multiple steps?
Absolutely. Yes, you would be able to put a couple of small marks (one at X0, Y 0 and the other at X0, Y23) with a small V-bit before you release the clamps. Then you could reference these marks in the next setup with X back in the zero position.
Another method would be carefully measuring the placement of the workpiece for each setup. This can be aided with jigs or material stops.
The maximum width that will fit in between the sides is a little less than 26 inches. The front and back are open for shifting the work as much as needed
The maximum width the router can cut is 24' inches, but it can cut unlimited lengths using multiple setups.
Does this unit come with the controller and motors?
Yes, the E4 CNC router kit comes with the controller, motors, and power supply. The assembly manual can be downloaded from our website. The appendix at the end of the manual has a complete parts list. You will need a computer with a free USB.
What is your refund/return policy?
The refund/return policy can be found here.
What is the accuracy of the machine?
The accuracy is highly dependent on how hard the bit is pushed thru the material. The theoretical accuracy is 13 microns (0.0004'). However, there are several things that add to error.
- bit deflection
- belt stretch
- micro- stepping
- lead screw error
- frame rigidity
- bit size configuration in the g-code
- backlash
With all of these, the well maintained E3 CNC router will still be able to hold accuracy within a few thousands of an inch. (0.002' to 0.004'), or 50 to 100 microns.
The best way to hold tolerance is to make light cuts on the final pass. This reduces bit deflection, belt stretch, and frame flexing.
How technical is the assembly process?
The E4 manual can be downloaded and reviewed on the link above. We recommend that you download and review the assembly manual. You can also research grbl (the firmware), Universal Gcode Sender ( the g-code sender software), and F-engrave ( software to make the G-code). All are free and can be reviewed before you buy.
How loud is it?
The E4 CNC router has a DeWalt router. Routers are loud enough that you will want hearing protection. One reference I read online quoted 103 dB.
Is the controller 2-1/2 or 3-axis?
The E4 is a full 3 axis machine.
How are the pieces clamped on the table bed? Does the unit come with hold down clamps?
The spoil board bed has 1/4'- 20 inserts. The kit comes with 1/4'-20 screws and wing nuts along with 8 clamps for mounting the workpiece. The assembly manual can be downloaded and reviewed on the link above.
What type of material is used to make the frame of the machine?
The E3 CNC router frame is made from 6 mm 5 ply Baltic birch. The spoil-board is 1/2' MDF.
Can this run on Windows 10 and would I need to install a software?
The E3 is a CNC router that uses an Arduino microprocessor to interpret the g-code file. The firmware is called grbl ( is pre-installed on the microprocessor and uses a USB port to receive serial port information (G-code) from software on the computer. I recommend UGS Universal G-code Sender software to send the g-code text file to the controller.
GRBL and UGS use standard g-code text files to operate. Both have good documentation on their websites showing their capabilities.
Yes, you would be able to run with Window 10 as well as many other operating systems.
