And as for the 4 decimals that rhinocam outputs, i just went to postprocessors edit and changed there the number of decimals to 1, that fix it

I just have noticed that the problem of the extra spins may be the negative degrees, i just remove the - in a couple of lines and it went fine, i just dont know why that - are there

Thanks Greg it worked now, i was just doing it wrong. Just another thing:

I made a code with rhinocam for testing the 4 axis, I just made a 30mm radius cylinder and a finishing operation, so its just basic, just a constant Z height, but rhinocam outputs lots of decimals, like 29.9994 and then 29.9998 so it goes like steps, becuase it has to move the Z and then rotate the A a bit,  also its strange, cause the A axis goes to lets say 43.636 and then for the next that is 47.273, it just doesnt go the 4 degrees up(the short way), it takes the long way and spins more that it should, i dont know if it was that i made a bad code, dont you know where i can find a 4 axis test code ?

heres a piece of the code:

G21

i didnt knew that Greg, i have activated it and seems that nothing happens. I went to config ---> toolpath and then check the box use diameter for feedback and A-rotations enabled, then over the settings tab--> rotational diameters i change the value for the A, and the jog the A axis with the hotkeys, but it runs always at the same speed. How is this supposed to work? i thought that if i put a big diameters it will slow the speed and with little diameters it will spped up, but i change this and dont see any chage, im doing something wrong?

Thanks olf im going to check the link right now.

Greolt: but if you set the speed and acceleration of the X, Y and Z axis similar to the rotary A axis, the will move to slow, im having this problem and dont know how to fix it

Hi spacecat, i think i have the same problem, where you able to fix it? i think i could be the acceleration
