Thread: y axis belt tensions for VLS 6.60 laser

    y axis belt tensions for VLS 6.60 laser

    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?

    For anyone wanting to know, the adjustment screws are at the back of the y rail, 1 each side of the belt. You do not need to disassemble anything to get access to the screws. They are just counter sunk screws that wind the spindle of the pulley out as the top of the screw is wound down. I'm still waiting for Universal to get back to me for the belt tension, I have been given 3 different figures (100g, 150g and 200g) so decided to ask Universal and get it from the source.

    Thanks for that, you wouldn't happen to have the y axis files?
