Thanks, I didn’t re-cover my OG steel sheet (it’s still working just fine), so no need to remove any glue, just clean up. I got some steel sheets cut up and covered them with some PEI purchased elsewhere, and this guide was perfect.
For me, this was definitely the most frustrating part of the entire build. As I look at it, it seems to me that the insertion of the nylon is really just to have it be held in place while you get the rest of the cabling under control coming out the back of the extruder assembly. Once past Step 39 the zip ties will assist with keeping the nylon in place. So yes, only a couple millimetres of insertion is enough here.
But, that is a tough couple of millimetres!
My suggestion would be to adjust the hole to be a wider diameter with a hook ridge around the circumference 10mm into the hole. Then with a notch on the end of nylon it would simply slide in and lock into place, holding it there while the rest is done.
M3x25 fits fine. When you put the nut in (Step 6) it says to put a longer nut in from the other side and tighten it up to pull the nut further in.
I used an M3x18 and that was enough to get the nut all the way in. If your M3x25 is not reaching, give that a try.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
