<span>Hi dear All,<br></span><br><span><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">
I have noticed a problem with the rotational axis of the USB 4D-Stage.<br>
<br>When the motor is driven without the belt that transmits the movemente to the sample holder, it<br>
works perfectly. The problem is that when I use the belt to transmit the movement from the motor<br>
to the sample holder, there is a shift in angles between the axis of the motor and the axis of the sample<br>
holder, and every time I perform an angle movement the shift increases. At the same time the position of the<br>
motor axis is affected causing no repetability when using the belt. So, I
can't position the sample to the exact angle I desire. <br><br>I don't know if the problem of this situation is because the belt is not so tight. I would like to know if some<br>
of you have had this issue and how could you solve it.<br><br>I have thought to solve the issue replacing the normal pulleys and belt for timing pulleys and belt or</span>
