Can anyone help with what the tension should be for the y axis belt on a vls 6.60 (or a pointer to a service manual)? I have seen the guidelines at engravers network but the 175g recommended seems a bit off. Measuring the belts before changing them I got 230g, given the belts haven't been touched since the machine was installed then 175g seems a bit light.
Furthermore where are the screws to adjust the belt?
