Z Calibration. Is this me or the Printer?
Okay, so I've had the MINI for awhile but not used it much because of time commitments to other things. Now I'm finally getting to use it but can't get the calibration right. I do the calibration and adjust the z until I get something that works. I make a print. Not a great print but it's the right shape and not too bad. Without changing anything I print the same print again, when it starts, the nozzle is now hitting the bed or is way above it. Am I doing something wrong? Is this a printer issue that has a fix?
Oh, and these prints are just the Prusa test prints that come on the USB drive.
Just wondering if I should throw this thing in the trash.

Sounds like your SPINDA is loose.

@redcanar
could you provide please more details?
What calibration did you, úincluding first layer calibration?) how did the calibration end.
Great help for helpaérs are the picture. I would not advice after the first trouble (challenge ?) to fill in the vaste basket.

Try to tighten the screw that holds the Super PINDA a tad. If it's loose, the PINDA may slide up and down just enough to get your Live Z out of whack.
But if you're considering throwing your Mini into the trash because of this hiccup, maybe you should because there will be others down the road, for sure. 3D printing is far from being a foolproof technology like a toaster. But if you're willing to put a bit of effort into it, it's going to be a greatly rewarding hobby. And the Mini is arguably one of the most robust systems in that price range, so you're pretty well positioned for success.

Have you updated the firmware and PrusaSlicer presets? There have been related improvements made in recent months.

Not loose.

@fuchsr
I don't think it has a Super PINDA? Isn't that a recent change? Do I need to replace the sensor?
RE: Z Calibration. Is this me or the Printer?
If you've had it for a while, it's likely to be the old MINDA. The SuperPINDA is definitely an improvement over the old model but I have a hard time trying to explain what you're seeing (good print followed by a print where the nozzle is way higher or lower) by anything other than a loose PINDA, so buying a new one may solve the issue only if serendipitously installing it corrects a mechanical problem.
