CNC router software and training
« on: December 02, 2012, 06:59:15 PM »
What software is needed for design and application for the CNC router at the lab? Is there a tutorial one can use to get "prepped" before actually turning it on? Am using linux currently. Does an inkscape file work on the router?
Thanks in advance!

I don't know the details, but I believe they are using Cut2D from Vectric for the toolpath. http://www.vectric.com/WebSite/Vectric/cut2D/c2d_index.htm

You start with a vector format (not sure what the import formats are), and then you have to tell it material thicknesses, tools used, etc. and it generates the GCode...

Thanks. Inkscape for Linux has a gcode add-on that i've installed. Anyone have experience with that?

Scott, you can use the "trial" version of vectric 2D and the files it exports are still full-fledged files.  You can then bring them with you to the lab and utilize them that way.  There are tutorials on youtube provided by the company that teach you how to make pockets, etc.


It's an easy software to learn.

I've used the Inkscape Gcode-Tools extension for generating g-code for the mini Zen CNC. I was glad to be able to work in Inkscape, which is very familiar to me, and the output easily registered with LinuxCNC.

I could never figure out how to get the offsets to work correctly, so each of my gcode files were like 1"x1" off from the origin. I wound up using another program that generates gcode. From what I've found, I think a lot of people write their own tools to generate gcode.

These folks have had a lot more success using cut2d with the cnc, so I'd probably suggest that.

Thank you for the responses! I wanted to use a linux based software but can see the ease of use with the window's product mentioned.
Thought I was done with windows after installing ubuntu 12.10 but guess not. Oh well.
Maybe i'll meet some of you at the open house tuesday.
Cheers!

Scott, the system we use for the CNC is Linux.  Cut2D works perfect under Wine.

There are a bunch of open source home brewed gcode generators out there for various purposes.

http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators

That page links to a DXF to GCode generator, http://www.christian-kohloeffel.homepage.t-online.de/dxf2gocde.html
Inkscape is supposed to be able to convert from SVG to DXF, so that tool might fix the niche in your toolchain.

Another dxf to gcode generator: http://www.dakeng.com/ace.html

Are there written instructions for using the CNC router? I've dl the vetric 2d but can't save my work at home. there are nuances for setting up the router that I havent learned yet. Do you guys just experiment with the machine on scrap wood to learn it? Like how to move it to the rear to reset it quicker. Do you set the cut deeper to keep from splitting the bottom of the cut? Etc etc. I have lots of questions but not many answers yet.
Thanks for letting me rant here. Maybe someone can help me with it before the meeting tonight.

I'll be there before the meeting, hopefully. If I am, I'll gladly run over these questions with you.

Thanks to  responders. Success! I did the groundwork by using the cut2d tutorials and because they didn't save in the trial version I replicated the steps on the cnc router computer. Is it to be left on at all times? Had one mishap shown on the pic enclosed when the tabs were cut too deep and didn't hold the center piece. The second time worked out well. What a great resource this cnc router is! Anyway, Happy Hollidays to all.

Very cool! Yeah, just leave the computer on. It draws very little power, just the CNC needs to be off. Also, don't hesitate to add more tabs, if I'm worried, I generally just throw another two on. I'd say about one per foot of piece circumference with two minimum is plenty. Tabs are easy to fix, just take a chisel and hammer to them, really easy to get the piece out no matter how many you make. There's a screwdriver/chisel on the pegboard, or I might have left it near the CNC.


Looks awesome!
