Sensorless homing on V-MiniON, limits show 90mm instead of 180mm on X/Y
Hardware configuration:
- V-MiniON, Sensorless X/Y, SKR 3, RatOS 2.0 Beta 2
Behavior: Homing all axes works fine, but after done, X/Y values show 90mm instead of expected 180mm. When I try to move X/Y axes to zero, they stop at "0" at the middle of the bed, instead of expected left/front of the bed.
Which configuration entries should I change so that it would behave as expected?

Then homing doesn't work 🙂 The axes are supposed to move to the center after succesfully homing. (that's why it saying 90mm, ie 180/2).
Either tweak your sensitivity/current settings or post a video of the homing procedure if you can't get it to behave
Sounds like it triggers instantly due to too low current or too high sensitivity. It's a quite common error to make.
I have made some experiments, it seems to always move exactly 90mm towards the end, then stops and lies to me saying it's done.
If I shut it down, then move the print head and the bed manually all the way to 0/0, X and Y move 90mm (which means in this case exactly to center), then says it's done.
If I shut down, then move the print head and bed manually to, say, two thirds, the motors will move and push against limits until they think they traveled 90mm, then says it's done.
They never move back to center.
Like i said, it’s triggering instantly. You need to tune current and sensitivity
It goes
1) home x
2) move to center
3) home y
4) move to center
5) home z
If that’s not what’s happening you’re getting bad triggers as in 1) and/or 3 happens instantly with no or little movement, because your settings are wrong
Indeed, X/Y are always triggered. Do I need to play with stepper jumpers on the SKR 3? I left them all as the default instructions detail.
Solved. The little jumpers on the board were not there.

Ah yes, sorry i should've started by covering the basics. Good you fixed it, I'll close this 🙂
