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 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:
Ask inventables for a replacement g-shield
Pick up one of those green connectors ( maybe inventables could provide these for people with this problem?)
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.
