Burr Removal

[BUTCHER]

I use the Tormek T8 with the standard stone graded fine and the leather honing wheel with cal cap angle calculator.
After setting the angle on the knives I remove the burr with the leather honing wheel at the exact angle. this worked well at first but now the honing wheel does not remove the burr at the exact angle or even 1 or 2 degrees higher. Any help on what the problem could be would be greatly appreciated.

Do you always put just a tiny amount of PA-70 honing compound right before you hone a knife ? I found that more efficient than putting a larger amount less frequently.

I haven't been putting any extra on for a bit which might be why it's not working as well.
Tried that this morning and it worked much better.
Thanks
