Printed bolt threads are wrong direction CoreXY

Well it is occasionally handy to be able to home the X axis without having to first home the Y axis to get it in position.

Before I put the switch on the frame I thought the same thing. In the year or so that it's been that way I haven't missed being able to home the X axis independent of Y.

It is a good point, I am thinking about to stick it to the frame. May I ask you that tunnel switch, is there any advantage compared to normal switch?
I assume you're referring to the optical switch. The ones I used have an LED on board that indicates when the light is blocked and that can be handy for making adjustments without having to check the display connected to the controller board. The type of snap action switches I was using always have some hysteresis that can make adjustments a little tricky, especially setting the Z=0 position in my sensorless printer. The optical switches have much less hysteresis. I'll be converting the Z axis endstop in my printer to optical next, now that I have figured out a way to make very fine adjustments.
I'm have mixed feelings about the optical endstops. The snap action switches I was using are extremely reliable. I don't know how well the optical switches will hold up at 50C. I haven't done any testing to see if the switches are affected by ambient light. These type of things are used in industrial machinery all the time so it's probably not an issue.
