I have been using belt calculati on feature to determine the combinati ons of component s that would work for my applicati on. I love the feature, Thank You. I also use the    https://sdp-si.com/eStore/Catalog#    website to purchase GT2-5mm pitch Timing Belts and Pulleys. Noticed that Gearotic has a 8mm pitch but no reference to the 2mm and 3mm pitch's SPD/SI supply, and they no reference to the 8mm you have.

It all got me to wondering, what other sites have different component s and different gears and where your "goto site" is to reference your selection s you have chosen?

If others here have good sources of component s please post, Thank You

(Note: Choose METRIC option, then using the Part Index; It was under Belts & Cables / Timing Belts Trumotion)

A programme r with a conscienc e 
Your a real find, and a very impressiv e gentlemen .
Thanks for sharing your loves & interests with us.
I'm sure I speak for many, that without your generosit y we would never know what is possible for us hobbyist & hackers.

Nice clean HiRes file lines, loads fine now.

Did have quite an issue getting Assimp to install and work but did manage finally, that's a cool tool too. Exports a very nice .obj file.

The major issue was the DirectX 9 installat ion. Had to extract the dxwsetup. exe to a folder and then run as admin.

Thanks again.

What is asimp? could not find it on google.

I tried Rhino 4, Rhino 5, ArtCam, Autodesk Inventor Fusion, Solidwork s & DeskProto 6
nothing works to import the stl file

mine came up 4.87?

Slight error, when you use the up/down step arrow buttons both rotate at the same time.

Could these be programed to cut on a 4th axis, linear travel cut using a ball nosed tapered end mill?(Gearotic)

Or if you could provide a solid stl, could then use a CAM program with rotary axis Post.

Would be an interesti ng project to watch cut.

with cutter offset should be able to create the tooth profile for the zero backlash.

I changed tool diameter to .0325 and got a change in locations of the loops.
Has something to do with tool diameter because I tried .015 and it worked fine.

Sweet Job, Thanks for the added control. 

Why is it that when I use the Rotate on/off in the GTA that it always jumps back to the default/start location? It does not stop and hold position. There is no way to step forward or reverse. and I thought you were going to use hot keys along with using button icons. I would like to be able to zoom in and step thru gear tooth interacti ons.

Very Nice work 
Do like the looks of the rounded tooth profile.

Have a question on accuracy, It looks like it might be off by a couple of seconds per minute based on the video. How accurate are these type of builds and can they be adjusted easily?

FWIW: update on the linux "gddrescue" program:

5 days to complete the bit by bit transfer of one bad usb drive to a new larger usb drive. Showed 783 errors, 3735kB error size and thou the disk would not boot because the operating system needed repaired. Used the Win 7 install disk and choose the repair option. System is back up and running. Whooo!

I had tried the linux "dd" bit transfer program but due to physical disk errors it would not work.

Just letting others know that the gddrescue program works for saving a lot of grief.
I am sure there are option I could have used to make this work faster and more efficient . But for the first time use, I just wanted to save all the programs I installed with the data they create and use. Happy Computing .

sudo ddrescue /dev/sdb /dev/sdc
 

I am surprised Norton did not give you issues. Had to address the problem when I upgraded Gearotic and tell Norton it was safe every time. When the subscript ion ran out I uninstall ed norton, about a week later the hard drive puked. (now I am attemptin g to get gddresuce to save the bad disk to a new drive, hope it works) Think I will use Linux for internet access now. These hacker programs are getting out of hand. Not sure the reason people feel the need to create Malware.

Is there an option to add the rotate by step CW/CCW buttons on the other tabs that only show rotate on/off? Or are there hot keys that we can use to step?

Your program just keeps getting better

Also dxf files created by Artcam and Rhino also works, Thanks.
