GearHeads Corner

I am getting a number of G03 lines in my code which are generating the circles seen in this gcode output image. I am using version 4.710. I have turned off the "Rounded Corners" option. When these lines of code are edited out, the gear looks fine. Am I doing something wrong?

Hi:

  No, its a bug. Youll find that if you change your point distance setting ( up or down depending on the tool used) the circles will go away.  Its a hard to find bug in the pocketer that creates entire circles when the small arc created is so small it reaches epsilon proportions and is then interporeted as a circle. This is a bug I hope to have fixed soon in GM and will not be present in GT at all in the recode.

Art,

Thanks for the quick reply. I tried adjusting the gear point distance variable up and down, but it didn't correct the problem. I should point out I'm using inch units, and my tool diameter is .0625. Is there a recommended setting I should be using?

Russel:

You can try lowering the number of spokes by 1 or increasing by 1. Its a very strange numerical problem that causes it. Ive always been able to make it go away by modifying one thing or another to stop the rounding error. Ill see if I can get that fixed withiin the next couple weeks fr the next release. It usually shows up on circular or damper type of spokes.

Thanks for the suggestions. For this project I'll just hand edit the files and will look forward to the fix.

Russ:

  Do me a favour though, save your project and post the file here. I know your tool is .0625 , Id like to run some tests with your settings. Also, let me know what you have set for point distance. If your in Inch it shoudl be around .001

Thx

Russ:

  Just a followup, Ive found the problem and Ill release it this week. Should make the Gcode much more reliable and wit no circles.

Thx
