Y-Rail Female Plugs - Press fit in tube?

#onefinitycnc

How do the pieces of plastic that hold the female connectors for the Y-Rails mount in the end of the tubes?

Are they just a press fit?

I have a pin on a Y connector that is pushed in a bit and I want to repair it. I have a dowel going all the way through the tube and I have tapped lightly but I don’t want to break anything.

Thanks!

This should help …

Perfect! I called myself searching the forum. I did a text search but I guess I didn’t use the right search terms.

In the meantime I took an old pair of needlenose and ground them down to reach up in there and pull on the pin. It didn’t budge! I am wondering if it has always been slightly recessed.

I connected everything and - this may not be good - tested each Y motor seperatly by unplugging one and moving the gantry. I did this for both motors and both seem to move the gantry in the Y direction.

Considering how much work it would be to disassemble this entire thing to get to the bottom of the Y rail I may just let it be and test thoroughly.

On a side note… I just discovered that the Z cable does a crossover at the end of the X rail. I checked the forum and sure enough… dang. Now I have to re-do one of my plugs. Oh well. :slight_smile:

Depending on how much you love your table… You can drill a small hold directly under the bolt and access it that way.

That is how I did it. :sweat_smile:

I gave it one more try with my home-ground pliers and it popped back into place! Yay!

I’ll post pictures of my build when it is completed and you will see why your suggestion - while a great and logical one - would have made me cry. :slight_smile:

the internal wires in the x and y’s also have a cross over.
So: x, y1, y2 and z curly cable all have a wire cross. If these get put in differently, they will blow a motor driver in the controller and render your machine inoperable.

I may have dodged a bullet.

I was using the controller to move it 1cm at time. I noticed the motor was trying but not moving. Then I investigated and discovered the cross-over. I may have tried it 3 times.

Once I re-did my plug it worked fine. Hopefully it didn’t weaken the driver. Solid State components usually are OK until they aren’t. So maybe it will be OK.

Essentially, the way I made the cables is I put each end on the original cables side by side and made a map of the continuity. Then I made my cables to match. Since I was using the Z cable from the controller without the curly cable I didn’t discover that two pins were different going from the curly cable to the straight cable.
