CamBam - Tutorial : Text Engraving
This tutorial describes inserting text into CamBam and genertating an engraving operation from it.
To insert text into a drawing, use the Insert->Text menu option, then change the text properties in the object browser.
Multiple lines of text can be entered by clicking the elipses [...] button to the right of the Text property.
The text properties are:
Creating Engraving GCode
To create some engraving gcode, select the text then select the CAM->Engrave menu option.
For shallow engraving (0.3mm), try these properties:
...And "blow my bike up!", as Grandad would say...it even works !!!
Not exactly high art, but the letters are quite small (3-6mm) and plywood isn't the best precision engraving material but at least CamBam and my machine are playing together nicely!
To create thin engraving, ideally a 'stick' font should be used, that is a font with no thickness. One that I am aware of is Camworks.ttf; this looks nice on screen, but the resulting toolpaths are pretty awful (using my awful non-optimised gcode generation code at any rate). Any recomendations for nice stick fonts, preferably in the public domain, would be extremely welcome.
NOTE: I tend to use Metric and CamBam was designed with Metric in mind, but it does support imperial units. For information on changing the drawing units, see the getting started section.
