Maker of CamBam supports Workshop 88 makerspace!

HexRay supports Workshop 88 with a complimentary
CamBam site license & member discount!

Workshop 88 would like to extend a big thank you to HexRay for supporting the our CNC efforts by allowing us unlimited use of CamBam on club Windows and Linux computers plus a discount on CamBam to Workshop 88 members.

For more information about CamBam, check out their website: http://www.cambam.info/

From the website:

CamBam is an application to create CAM files (gcode) from CAD source files or its own internal geometry editor. CamBam has many users worldwide, from CNC hobbyists to professional machinists and engineers.
CamBam currently supports the following:

  • Reading from and writing to 2D DXF files.
  • 2.5D profiling machine operations with auto-tab support
  • 2.5D pocketing operations with auto island detection
  • Drilling (Normal,Peck,Spiral Milling and Custom Scripts)
  • Engraving
  • True Type Font (TTF) text manipulation and outline (glyph) extraction.
  • Conversion of bitmaps to heightmaps
  • 3D geometry import from STL, 3DS and RAW files
  • 3D waterline and scanline machining operations
  • Extendable through user written plugins and scripts

Be sure to check out their CamBam bundles with Mach 3 controller and CutViewer too.  Personally, I purchased the full CamBam + Mach 3 + CutViewer bundle; I couldn’t beat the price and I’ve been happy with them to this day.

As if that wasn’t good enough: “Unlicensed CamBam installations will continue to work after the 40 evaluation uses are up and allow editing drawings and viewing toolpaths.  However, g-code output is limited to 1000 lines, so another option is for people to work on designs at home, then bring them in to the group’s licensed computers to generate g-code.”

This level of support from HexRay is fantastic and something Workshop 88 greatly appreciates!


I have been using CamBam as my go-to CAD-CAM software for many years, to see a sampling of the kinds of things it can do, take a peek at some of my personal CamBam projects:

3D vacuum forming mask mold master for independent movie

Utility shelf for beverages and keys

Wall artwork – Wooden V

Engraved Bahr family crest

Atari Adventure engraved sign

Philosophy Custom Guitars engraved sign

Working miniature TV

Halftone portrait

Stay tuned to see CamBam powered Workshop 88 CNC projects!

…and on behalf of Workshop 88:

THANK YOU Andy @ HexRay!

Shapeoko plots!

Our shapeoko has produced its first output under control of g-code!  It’s taped up on the refrigerator at the space. 🙂

Inkscape converted a bitmap of the logo to a .svg, the  gcodetools extension generated g-code, and vi did the final modifications. 🙂 The .svg needs a little cleanup, but it was more than adequate for this first test.

We now have a profile that’s calibrated to within a few percent for X, Y, and Z, though there’s still work on max speeds and accelerations.  This plot was made with a ballpoint pen in a very crude holder.  The bitmap-to-path converter generated inside and outside paths for the lines, so the mismatch of the actual plotted paths gives us some insight into opportunities for mechanical improvement of the shapeoko/penholder system.  While the penholder is responsible for some of the tracking errors, we still have a lot to do to tighten up the shapeoko.  The plate joining the Y and Z axes wobbles surprisingly.  But it’s starting to work!

Update 10/2/12: Using the very convenient test facilities of the axis setup in linuxcnc’s stepconf tool, I maximized travel speed on all 3 axes.  The shapeoko1 profile is getting pretty usable.  Here’s a little real time clip of it plotting.  This one used a Sharpie, and even though it only stayed in one spot while the Z axis raised or lowered the pen, the paper bled the ink into very noticeable dots every time it stopped.
