Deselect any unneeded geometry like the inner and outer circles. Select all splines making up the outside of the pulley by dragging the selection rectangle around these parts. This profile cambzm made up of a number of spline segments, so the next thing to do is convert them to polylines and join them together. Select the root of the file tree on the left where it says 12t-htd. With a few edits, these drawings can be used as is, but for simplicity I delete any unneeded objects and layers.Īs with many DXF files, there is insufficient or ambiguous information in the above example to get the drawing units correct, so the first thing to do is to change the drawing units to Metric. These drawings contain much uneeded information such as side, elevation and isometric views. When prompted for format, select Autocad 2D. Thanks Terry for the source files as well as CamBam beta testing. This example is based on the efforts of cambwm friend Terry aka MrBean.
Cambam tutorials software#
The main place for CamBam video tutorials is here: CamBam CNC Software – Video Tutorials There are also a number of user created videos. This tutorial describes inserting text into CamBam and genertating an engraving operation from it. Thanks Terry for the source files as well as CamBam beta. This example is based on the efforts of my friend Terry (aka MrBean). For information on changing the drawing units, see the getting started section.CamBam – Tutorial: D Profile. NOTE: I tend to use Metric and CamBam was designed with Metric in mind, but Any recomendations for nice stick fonts, preferably in the public domain, would be extremely welcome.
Cambam tutorials code#
(using my awful non-optimised gcode generation code at any rate). One that I am aware of is Camworks.ttf this looks nice on screen, but the resulting toolpaths are pretty awful To create thin engraving, ideally a 'stick' font should be used, that is a font with no thickness. Precision engraving material but at least CamBam and my machine are playing together nicely! Not exactly high art, but the letters are quite small (3-6mm) and plywood isn't the best And "blow my bike up!", as Grandad would say.it even works !!! To create some engraving gcode, select the text then select the CAM->Engrave menu option.įor shallow engraving (0.3mm), try these properties: NOTE: Bottom is actually the baseline of the text.Īs per DXF I may add other options to differentiate absolute bottom and baseline. Top, Center or Bottom (relative to Location). Left, Center or Right (relative to Location). To enter multi line text, click the button after this property. I'm not convinced this is correct yet, but it is on the list ofĪngle in degrees to rotate the text about the alignment point (Location). I have used height as relative to the height of a font capital (ascent?). I have had some issues with this and at the moment, This is the text height in drawing units.
For a bit of fun, try clicking on this option, selectĪ font, then use the up and down arrow to try different options.
This is the font name to use for the text.
This scales the distance between each text line. Would double the space used for each character (but not the character itself). This option scales the width used for each character. The intention is to use it to defineĪlignment options that evenly spread the text between two points, or perhaps as an alernative to the Rotate option. The TextAlignmentH and TextAlignmentV options are all relative to this point. This is the first and at the moment, only alignment point. Multiple lines of text can be entered by clicking the elipses button to the right of the Text property. To insert text into a drawing, use the Insert->Text menu option, then change the text properties in the object browser.
