Gcode for spiral circles.
I don't know this is the right thread to ask for this. I am looking for Gcode to draw spiral circles like this prefer in size about 24 to 36 inches diameter.
Thanks Rocky |

In CorelDraw there is a tool that does it for you. I took it with 15 rings and exported it to DXF file. Changed it to .zip extention as the forum did not allow me to post a .dxf file. Just rename it back to spiral.dxf..otherwise let me know and I can PM it to you...just tell me how many circles you want.

I will be using Mach3 for the controller software. I am hoping to get the machine test run early this week if everything as planned.
Thanks Gerald for the pointing the commend code and Kobus for making the file. |

Let's try again.
I know that my CorelDraw makes funnies with exporting .DXF files. The EPS version is 8Meg...bit big to post here, but here are the .AI and .svg files....again changed the extentions to get it on the forum. spiralsvg.doc spiral-ai.doc |

Probably too late, but you can cut a spiral in Mach3 using G2 or G3. Here's a post from Art that explains it.
Gerry Mach3 has a hidden feature that allows for spirals that aren't to large.. A G2/G3 command does not really need to be fully an Arc, its allowed to stretch about .5 inches in any domain, so a simple series of non arc G2/G3's is really a spiral.. for example, here is a spiral of a .5 stepout each line.. normally an illegal command, but Mach3 will allow it up to 12.5mm's or .5 inches.. g0x.5y0 g2x1Y0I0J0 g2x1.5Y0I0J0 g2x2Y0I0J0 g2x2.5Y0I0J0 g2x3Y0I0J0 g2x3.5Y0I0J0 g2x4Y0I0J0 g2x4.5Y0I0J0 g2x5Y0I0J0 Thanks, Art |

G-Code for spiral of different # of turns
Hi, Everyone
I am a newbee; I need to generate G code that I can use to cut several spirals, all 14" in diameter, however, with different number of circles. That is, one with seven concentrics, then with 6, another with 5, another with 4. What I am actually doing is dispensing instead of cuttink. I have a dispensing valve where the cutting tool is supposed to be; I have an actuated valve that opens and starts dispensing in a spiral. dpending on the tickness and pressure used, I need to make the cnc move from outside to the center dispensing in a spiral (fast, less concentrics, slow more). Thank you for your help. Dan |
