Thermwood G-Code reference / new CNC carving software

Postby Daniel Carr » Fri, Aug 05 2005, 1:51AM

Greetings,

My company has developed a 3D CNC sculpting/carving program called VS3D. I'm looking for documentation on the G & M codes accepted by Thermwood routers so that I can add a Thermwood-specific post-processor to VS3D (if necessary).

Any information on where to look or how to obtain such a reference would be appreciated.

PS:
VS3D has similarities to ArtCam Pro, but at a significantly lower cost.
The VS3D web site can be viewed via the link below. Thanks.

Hi Daniel,

I've attatched a zipped file containing two word documents that have descriptions of the M & G codes supported by the Thermwood controller. Hope this information is helpful.

Thanks for the info !

I have a couple questions.

What is the expected file extension for G-Code files (\".cnc\", for example) ?

Are there any characters required at the beginning of the file (some systems expect a \"%\" and/or \"01\" at the beginning) ?

Do you have an example of a simple Thermwood G-Code file that includes a tool change operation ?

% Will make the controller by pass particular line of code, as will putting parenthisis around a particular line of code.

Sample 3 axis header:

G90 (SET MACHINE TO ABSOLUTE DIMENSION MODE)
SET ZSHIFT =.75 ( MAT. THICKNESS, USES DAYLIGHT, SETS Z OFFSET)
G51 X# Y# ( X AND Y Fixture Offset )
S18000 (SPINDLE SPEED)
T1 M3 (TOOL CALL, SPINDLE ON)
G0 X# Y# (INDEX TO FIRST CUT POSITION)
M31 (Check for spindle to be at full speed)
G0 Z# (Z PLUNGE TO POSITION JUST ABOVE PART)

Thanks, Ryan.

I've just released version 1.55 of VS3D which now has additional flexibility on the G-Code output to accomodate Thermwood routers.

Details about the program can be seen here:
