Change Head in UTM

I brought a very initial version and installed for months already. I always have probem to change head from UTM tool, the reason is the head change requires high accuracy of X, Y,Z position stored in memory but the physical movement will shift position.

Would like to know if there is same problem from feedback and if there is improvement in V1.4. I am interested to order V1.4.

Could you please elaborate a bit more on your detailed problems so we would be able to help you…?!
