Centering Issues x Mechanical adjustments
I´m constantly experimenting issues when it comes to center the image right onto the piece to be engraved.
Its the third time I get the engraving positioned a little bit ( 1,5mm in average) to the right. I realized that one of the possible reason to that, is related to the belts tension adjustment. In the very first time this issue was presented, I adjusted the belts a little bit tighter, in order to make both of the axis get to the base plate at the same time, as the procedure described in the manual.
Apparently the issue went away...
The problem is that from time to time, the belts turn to get loosen again...and the image goes out of center one more time.
I would like to know if is it possible the belts are defective, or any other mechanical issue that could be repaired with spare parts or any kind of adjustment?
This time, I tried to do the opposite. instead of tightening one of the belts, I loosen the other one, to the point of both black plastic pieces got to the base plate at the same time. Consequently I had to redefine my x0,y0. Did I do right?
