To test the setup and installation of my new Revolution rotary unit I mounted a rectangular piece 1.25 x 1.35 x 11 inches. Using the rotary option in my Vectric software I set the project up to simply round the spindle using the Rounding Gadget toolpath with the target diameter 1.25. I used the MASSO Wrap Y2A PP with Z zero at cylinder axis. The work piece homing was easy enough except that the Y axis was at the center of the work piece while Vectric XY Datum was left front corner. To resolve this I used a -1.964 (1.35/2) to recenter the datum position and used a 0.25 EM bit. The carve went well except the final diameter was 1.16 rather than 1.25. Has anyone else seen a Z cut about 0.1 inch deeper than expected? ![Screenshot 2025-04-27 150916](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/6/4/64f6b37f59371155d26ae89cdd20a6458ff10266.png) ![IMG_2819](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/d/e/de2d1f3e82c40f66fce73dbaba732cf819efed0f.jpeg) ![Screenshot 2025-04-27 150916](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/6/4/64f6b37f59371155d26ae89cdd20a6458ff10266.png) ---

Correction: The -1.964 was half of the unwrapped Y value NOT 1.35/2 ---

So I checked my practice rounding toolpath pieces. They were supposed to be 3" in diameter. They actually measure 3.1145 " in diameter. I did use the tool probe block for the Z height. Maybe there’s a calibration for the probe that can be adjusted? Or it’s leaving a finishing pass allowance? I’m not sure ---

So… how are you controlling the dust collection? ---

Word to the wise, never leave a chuck key in a chuck when you finished. Bad things can happen. ---

This was my first run. Have not addressed dust collection on the rotary yet. It looks as if 1F may have a new option that could work on the Rotary. Now that I know the Revolution actually works I will begin researching. ---

Absolutely, I knew someone would mention that when I posted the picture. 🙂 ---

I have done some more test runs. The Z is consistently 0.09 too deep. I was thinking of changing the offset but will do a measurement from the center point (using a pointed router bit) to the surface of the touch-off platform. ---

Not the correct way but an easy work around would be be to use the touch-off plate to set Z zero, then manually set Z zero off the touch off plate with a .09 feeler gauge, then reset zero ---

Could you guys explain the process you use for G code co-ordinate? I’m not an expert with how you use those settings. Thanks ---

The measured off-set is 0.045 inches greater than that stated in the instructions. That difference would account for the 0.09 diameter difference. Likely manufacturing variances. I adjusted my off-set to accommodate. ![IMG_2820](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/6/b/6b977c7efb6ed5426c528259e89f7ec826f0701e.jpeg) ![IMG_2822](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/5/0/50469dddc73f60148b133eef5de8a14d4bf8ff33.jpeg)
