I use Inkscape 0.46 to generate my gears--see my post from Tuesday. Here's a screenshot of the menu Terry talks about.

Dana--Thank you for your definition of runout and notes on HDPE.

I don't post here very often, and it feels great to still get the great feedback that you guys are giving me. I feel privileged...

I'm getting somewhere. I adjust 3 motors to take as much slop out as I can. I also adjust the lower bearings on the YZ car--one is loose enough to turn over by hand, and the whole car wobbles up and...

Khalid--I have all these old CDs lying around, I'm trying to come up with /some/ use for them. I am toying with the idea of making a grandfather clock out of them. I like the irony of using a...

Scott--I use an Amana Tool 45190, 2-flute straight bit, 1/16" diameter, 3/16 length, 1/4" shank. Different speeds from 3,000RPM to 15,000 yield similar results. I hesitate to push it beyond 0.75"/s...

24, 45, 64

Dana--I use 20° and .22" pitch. These numbers aren't particularly important to me. I want the smallest gears I can make out of this material on the Bot.

You can also try my DXF a couple of posts...

Jerry--you may be looking at a pixelization artifact.

Gary--thank you for your suggestion. The first file (red on black) is a bitmap export of the DXF. I see no problem with it, furthermore I see no problem with the .art file or the .sbp as it appears...

Thank you guys for jumping in o this one. I am grateful for all your feedback.

Ken--the defect moves as you say. The tool cuts the inside of the large gear counterclockwise. The artifact is on...

I am cutting involute gears from polycarbonate sheet. I start with a DXF, import it into PartWizard, and generate inside and outside toolpaths. The curves look fine in PW. I use a 1/16 straight bit. ...

Thanks Bill

Bill, thank you for the explanation.

The reason I'm asking is that I'm working on a Z adjustment program to allow engraving on uneven surfaces. I think I mentioned it to you when you were in...

Thanks! So C#X sets system variable X from the custome variables file?

I see this command in .sbp files sometimes. What does it do? I can't find a reference to it either in the Command Reference or the Programming Handbook.

I like Marvin's "work airplane" on his site!

Lonnie,

Now I know who to go to when the time comes to put a prop on my MiniMAX! I'm quite impressed with your operation. Seems like the business is good, which is great! Let me know if you need...

Andre:

I wrote my own software to generate ShopBot part files from images. Email me a photograph and I'll send you a preview image. If you like the preview, I'll send you the .sbp file to cut...

Looks very nice! Is it a parallax effect, or are the Alpha and the Omega not in the center? Or are the left drawers wider than the right?

Ari.

The program does the math, you don't need to worry about it.

Are any of you guys coming to San Mateo from the South Bay? I have an 8-foot piece I'd like to bring with me (along with smaller pieces), but I can't fit it in my car. If any of you have space in...

Not as good as yours, but I have a photo. This is how far the 2'x8' Flatiron Building mosaic went in my car when I brought it home from the shop. I really need to buy a truck.

Ari.
