@Zax correct, it never dropped even with quite a heavy pen attached. I know wd40 isn't a lubricant but it's all I have on hand at the moment and I thought I might as well give it a go. Do you have any suggestions for how I can get it moving?

Pen holder rail is very stiff
The rail that the pen holder mounts onto is very stiff. The carriage definitely doesn't fall under gravity, and is even quite hard to move when I push it with my fingers. I've tried scraping the inside of the track to remove any grit and spraying some WD40 on, but that doesn't seem to have helped.
Is there anything I can do to make it move more smoothly?
