New simulation mode (video tutorial)

The attached video demonstrates how to turn a 2D model (given as an SVG file) into a GCode toolpath.

Most importantly this video shows the new simple simulation mode. It is basically just a fast motion visualization of the toolpath progress over time. You can adjust the speed of the simulation. The visual result is quite similar to an EMC2 simulation. Just the path control mode (G61/G64) is ignored, thus you will not see potentionally rounded corners due to speed optimizations. Read more »

Bei der ersten Einrichtung der Software für einen RepRap mit Generation6 Software und Sanguino Board gab es einige Hürden zu umschiffen. Details dazu sind hier im Howtowiki unter RepRap festgehalten.

Engraving with single-line fonts

Text engraving with single-line fonts

Engraving text is a nice additional feature for all kind of woodwork or processing of thermoplastics. It is always possible to just use regular True-Type fonts for this (e.g. by importing an SVG model file from [Bad Link]). But these outline fonts cause problems for small engravings, since the graver will probably remove too much material from of inside holes of the text. Thus the outline of the engraving will be ok, but the inner features of the fonts will be barely visible or they just look broken.

The upcoming release of PyCAM v0.4.1 will include support for single-line fonts (also known as stroke-based fonts) to overcome this shortcoming. Read more »

Configurable parallel und distributed processing settings

Multiprocessing settings

PyCAM v0.4 started to support parallel and distributed processing. This basically means that the calculation of toolpaths will use all available CPU cores of your machine automatically. Additionally you can also use some commandline arguments to connect to remote worker servers. This leverages your local CPU resources to process even huge models with the help of remote PyCAM servers in a timely manner. With the new upcoming release v0.4.1, PyCAM will also allow you to configure these network connections via the preferences dialog of the GUI. Read more »

Visualize tool moves to safety height

Submitted by lars on Sat, 11/13/2010 - 00:14
Tool moves to safety height

The latest release of PyCAM (v0.4) displays the cutting paths and the “safe” moves (at safety height) in a quite simplistic way. Basically the “safe” moves are visualized as direct connections between the previous and the next cutting move. Thus some users were confused by the “line” going through the material. It was not obvious that this move occours at safety height and thus will not touch the model.

The latest development code of PyCAM improves the visualization by adding the moves up to safety height and down to the next cutting location. Thus the visual result is now quite close to the view used by [Bad Link]. Read more »
