A screw fell off the Shapeoko some time ago, I believe from the gantry. Does anyone recognize it?
I looked under the gantry but couldn’t find a likely spot it might have come out of.
What should I do?
Cheers!

Looks to be an M4 panhead used as an oil port cover:

Thanks! I’ll check. This video was helpful. The top screws are in place. I’ll check the bottom tomorrow.
You have now joined a very large group of people ( myself include ) that saw that screw laying of the table. Congrats ! Welcome

Refer to my 10+ times saying they’re being lazy not using PTFE threadlocker to account for cheaper manufacturing on the blocks. Never seen this happen once with hiwin.
Same thing happened to me. I couldn’t for the life of me find a place where it could have come from. I finally gave up looking. Then it happened again, and so I opted to take the HDZ off and found the now two missing slots for the oil port screws. A bit annoying, but unless you disassemble the HDZ or have a neck and back that can bend in the most unnatural ways, it’s very hard to find/see. Glad to learn I’m not the only one who had this issue.
