ID where Grub Screw belongs

I found a grub screw laying in my t-track that appears to have fallen out of my OneFinity Elite Foreman’s heavy duty slider or the PwnCNC Spindle. However, I don’t know from where, so hoping someone can help identify.

I reached out to OneFinity support but they told me “It won’t affect the machine…until it does, and then you’ll know for sure where it goes?” True, but I am hoping to address this before there is an actual issue :grinning:

Thus, I want to also rule out if it might be a part of the spindle so if anyone has any ideas I would appreciate it.

The little grub screw has a slot and measures approximately 2.8 mm. It is too small to be from the rail bearing. I think it is from the right side of the heavy duty slider as there are two holes there and I tested and it would fit - neither hole appears to have a screw on the right side but the left side does have screws. Can someone confirm for me if they have a screw like this on their Z-20? It has a straight slot on the ‘head’ of the screw.

Thanks,
Chris

Hard to tell from the pic if it’s the exact same grub screw… but I had the same thing happen to me, found it laying on my spoil board under the spindle one morning. About four days later, I figured out it came from the silver connector on the spindle cable. I attached a pic.
