SV07 Plus Z-Tilt problems and having to retry a print 2-4 times before it prints

When doing the z-tilt before a print. I’m having problems with getting the “Retries aborting: Probed points range is increasing.” It does this 2-3 times before it finally completes and continues. Here is a sample of the output from starting a print. Bed is level, z-offset set correctly, mesh is there. OrcaSlicer! Any ideas? This is a new machine to me, and my first foray into Klipper. I previously had an Ender 3 Pro that I had just outgrown and gave to the kids. I had to do only one restart this time (it’s normally 3 times):

Did you have any luck getting this fixed? I am still seeing the same issue. I can get one thing to print, then starting the second, it takes several hours to get the bed leveled again. What am I doing wrong?

I had similar experiences with mine and ultimately it came down to loose wheels on the z axis and loose Allen head screws on the bracket attaching the anti backlash nuts.

Once I got everything tightened up, my z axis troubles pretty much disappeared.

Hope this helps.

Greg

How much should I tighten those screws?
