Bed level not scanning whole bed on first print only.
In the video I was controlling via octoprint, but I tried it with the usb drive and it does the same thing. I went back to the default printer profile in prusa slicer (using 2.3.0) and am on the latest mini+ firmware 4.3.1.
Whenever I turn the printer on and start a print, it does not scan the whole bed. The resulting bed level is really bad. If I cancel that and immediately start again with the same g-code, it scans the whole bed and everything runs great. Every print afterwards is fine. If I turn the printer off and on again, the issue pops right back up. Any ideas? The printer is useable, but this is super annoying!
Edit: I tried to insert video, but it doesn't appear to be working. Maybe just copy and past the link.

I cannot see the video. You could upload to youtube and post a link.

I have been working with prusa support on this and took another video for them.

Were you ever able to resolve this? I'm having the same issue, and haven't gotten a successful resolution.
On my machine the X-Axis self test also fails. Does yours do that?
Bed level issue
My left axis test never failed. Eventually after a lot of tech support time, I RMAed the main board. A new one came in, and everything has been perfect ever since. I would go through tech support with your issue.
Bed level issue
Just to close the loop, I did get my printer working again, and my process is detailed below. Of course, this happened at almost exactly the 13 month mark for my printer, so there was no warranty available. Ultimately, I suspect that in my case this was a cable management or connection issue. The gory details are below for those who are interested.
I worked with Prusa tech support, and they recommended the following:
1. Tightening the grub screws on the X-axis gear. - This was also my first thought, so I performed a tear-down of the axis, and verified that the gear was properly aligned, and that a grub screw was secure against the flat surface on the motor axle, and that both screws were tight.
This did not solve the problem.
2. Replacing the X-Axis bearings. - While the X-axis felt tight when I moved it by hand, if I removed the print head assembly, the carriage moved as smoothly as I've ever seen. This seemed to contraindicate a bearing issue. I replaced them anyway.
This did not solve the problem.
3. Replace the MINDA probe with a Super-PINDA. - I'm not sure what this was supposed to do, and my MINDA passed every test I could think of. I did it anyway. Initially, the printer still failed X-Axis self checks, but the mesh bed levelling seemed to work normally.
After the install of the Super-PINDA, I readjusted some of the cable management that was a little disarrayed from the install.
After that, all self tests passed, and printing is working normally.
If I had this to do again, knowing what I know now, I think I'd cut the zip ties holding the X-Axis cables in place, remove the fabric sleeve, carefully repack everything in the sleeve, and replace the zip ties with less snug ones.
In the end, the actual solution is unclear, but my Mini is working. Hopefully this will help someone else who encounters this.
