PrintNC Project Part 4 - Y Axis Work

Показать описание
In this installment, I cover installing the linear rails on the Y axis supports and getting the BK12 block locations ready for later installation.
My audio problems are still ongoing, so please bear with me. There's traffic noise on and off throughout the video. My apologies!

Super useful to anyone building a PrintNC (or similar) machine! Successful punching, drilling and tapping are so important!

A huge thank you for documenting your build in such detail. Like you, I've watched many videos but it seemed that omissions we're in each.

The one thing that caught my eye was the lack of orientation marks for the 3D printed parts. It's implied that there's an arrow on some but it's just the shape of the holes. Yes, the holes form some semblance of an arrow but an unambiguous orientation marks would help.

Nice work Gene, strictly speaking those are called center drills. They are used on a lathe to drill holes in the end of stock so that it can be supported by a live (or dead) center.
Lots of folks assume they are used as pilot drill but the angle is completely different from a 118 degreee metal drill bit.

FYI, You DON'T need to drill every hole. Every other is more than sufficient.
