Limit switch connection loose?

Continuing the discussion from Limit Switches when manually moving the machine from easel:

@ChrisWundram

Especially the little molex pin connectors for the limit switches, those can easily come loose.

Any tips for improving those? I thought my crimping skills were just terrible, but your comment makes me think it’s not just me. They work, but they’re very loose.

I just post about what I think you are asking about here:

Screw Terminal - Header Pins Alternative

Maybe it’s a little strange, but I’m incredibly excited for this small, but important upgrade! I just received my order of screw terminals from AliExpress. It’s been a long wait since no one in my city sells these and Amazon.ca doesn’t seem to have them for a reasonable price. [image] Now I haven’t installed this yet, but I thought I’d throw this up here. I’M JUST SO EXCITED!! I’ve crushed a limit switch and stalled out my spindle all because I accidentally knocked the stock header connector…

I had the same problem. The “L” pins coming off the g-shield are too short. For me this was because the pins provided to be soldered onto the board had the black connector on the wrong side. I didn’t realize I could have moved it around. So, if that’s your situation, you have a few options:

1. Ask inventables for a replacement g-shield
2. Pick up one of those green connectors ( maybe inventables could provide these for people with this problem?)
3. Try resoldering the pins by removing them and flipping them so the longer pins extend from the board.

Once I had the pins in correctly, the black connector with the limit switch wires held on firmly.

I need a new limit switch connector and crimp terminals. The Inventables SKU is 30209-12, but other than it being a rectangular 8-pin, single-row female connector with 2.54mm spacing / pitch, I don’t know what connector it is. It seems similar to a Molex, but so does any rectangular connector. If I were to buy a Molex connector, I would need to know the pin-size on the header connector for the Arduino. Any advice would be appreciated.
