I have something weird happening. My switchwire is using a skr 1.4 turbo, 12vdc, sensor-less homing on X and Y with a probe on Z, other than that its normal. I just finished it and did the setup. I have one thing that is not working quite right. When I home I have to do one axis at a time. When I home X the gantry will go up a bit and that is all. If I move the head to the end manually and hit home then home Y and Z then all is fine and it words as expected. It prints fine and X is never a problem except when I hit home, it just sits there. I have adjusted the sensitivity to very all the way to not sensitive at all and it makes no difference when trying to home with the head anywhere on the gantry but at the end. When the head is at the end my sensitivity is 140 and there is no sound on end stop and it prints fine. I tried changing the driver, changed the stepper, using a different position on the card (tried the E0 and E1 slots to test if it might be the controller) and still got the same behavior. I am at a loss. Need some help on this one.

About normal for belt tension. I have tried replacing steppers, drivers, different sensitivity settings different slots on the board including E0 and E1 and X is just behaving badly for homing. So instead of fighting it any longer I just put in a end stop and moving on. Took 10 minutes and problem is solved. Thanks for the help.
