That support is only for resting the assembly when in the down non playing or non clamping position when you turn off the player or open the tray. The re-greasing is more of what helped.

Unfortunately the issue with the Laser assembly/carriage sticking going from Side A to Side B is occurring everytime again - it seems to struggle and stick when transitioning between going from the 'white' plastic track to the 'black' plastic track and transitioning at the same time from the fixed metal guide to the rotating metal guide.

Guides have been thoroughly lubricated.

At the moment Im thinking its wear and play in the rotating carriage..causing the rotating metal guide to be misaligned.

Ive a workaround in place - on the opposite side of the laser carriage I had noticed a lot of wear in the metal frame from where the laser assemblies white plastic wheel travels....especially noticeable where the transition occurs between the guides and from the white to the black track segment.

Took a punt and cut a small piece of material to use as a wear/grip strip..only an inch long by 1/4 wide..and installed where the wear is evident near where the laser assembly transitions...this worked first time and has worked since so far... how it works...it could be raising one side of the assembly or/and just gives a little more grip at the right position.

Will monitor how this goes...so far it works perfectly.

That's funny. I just posted about something similar I did & yours was the next post I read. In my case I replaced the entire rack, but I also had to build a little ramp like you just described. What material did you use? I used 1/16" double stick foam tape.

It was cut piece of Velcro like material - the soft side or loop side -

Still working like a charm.
