I don’t know if this is something anyone else has had but I noticed the y-axis extension cable doesn’t screw in all the way to the control panel. The thumbscrews bottom out before the connector does. I don’t know if it’s a problem or not but I fixed it with some washers. Here are some pictures of before and after. Notice the difference in depth of the connector.
langmuir, supplied some replacement screws came in one of the kits, can’t remember what kit, I believe the screws came with the control box
Oh nice I didn’t see those, maybe I missed them. No matter now anyway I think the washers work well enough.
