Unfortunately I only made one and I reduced the diameter per our previous conversation so won't help to measure now. I used a new 1/8" mill bit, but don't know if it is accurate to spec. I think the problem is on my end. I previously made a 28 tooth pulley with a .25 mill and that was too large of a ...

The longest I was able to measure without cutting the belt was for 23 lugs measured out to out at the base of the lugs. That measurement is 8.4 inches. The belt is a D and D Syncro Power Belt, 270 L. This belt fits the factory made 270 L pulleys I have perfectly. Would there be any chance that ...

Thanks again Art, I have been pondering how I can do the set up wrong. My assumption has been that once I enter that I want to start from the center of the pulley, all of your math takes over and all movements should then be based on the very center of the 0 start position. The only input I thought ...

Thank you Art. I will go back to the setup and see if I specified that wrong. I know I previously did a 14 tooth and it seemed exact other than using a .25 mill which was too large for correct profile fit.

OK, I went back to the tutorial and paid attention to the instructions on settings and found the place to set the origin to be at the center of the pulley rather than the lower left corner. Now I am wondering if anyone has had trouble with L pulley (timing belt). I just machined a 49 tooth and the ...

I have a Pulley blank cut to size for L type pulley. Is it possible to change the start location to be the center of the pulley so the machining location will be concentric to what I have ?
Thanks,

Thank you Art,
And I did figure out changing the dp for different sizing.

Art,
I viewed the video and see how it should look. That is not what I am getting. The first move for the A axis rotates a little beyond the profiling area and makes a full depth of cut pass that wipes out that side of the tooth profile alltogether. I did as you suggetsted and ran the roughing cut ...

I will try this out over the weekend and see what I can learn. Thanks for your patience and help.

I did reverse the rotary direction but it did not solve the problem. It still cuts wrong at the first rotary movement. I will double check that it is moving 360 degrees on the corresponding command and double check my gear blank sizing.

Thanks for your help.
