X50 oil port Location

Hello, this may be a silly but I’m going through the oiling maintenance video and it says there’s an oil port screw on each of the y axis rails and one on the X axis. I have the X50 rail and cannot find the port. Is there something different on this, opposed to the 35 mm rail?

The following may be helpful.


I found that hole but there is no bolt in it. Is that how it’s supposed to be or is it missing?

The second link I gave - under the photo - is from a thread that discusses that. Seems some X50s shipped with a missing bolt, and 1F sent replacements in some cases. I would reach out to 1F support.

Thank you. I’ll do that.

Only one side of the block gets a bolt, the other doesn’t need it.
