Been printing happy after replacing the parts that were damaged after the nozzle got pushed out until yesterday a new problem popped up.

Whenever the Z calibration or gantry leveling is started the printer start measuring all four corners like it should, but I see a lot of retries and eventually an error in the log of the printer.  
I’ve checked belt tension with the gates app and adjusted where needed but sadly that wasn’t the solution.

Can the bed be warped of the motor driver be an issue ? Z-sensor maybe ?

You may have to pre heat the bed before running the bed leveling. If that fail rerun it just after, that should works. If that continues to fail, contact the sovol support.  
If you fixed it but that continues to fail too frequently, there are more advanced parameters… But firstly make it works with regular features to exclude any mechanical damages

Last week I did some more diagnostics and I printed an M12 probe holder to try that.  
When switching the probe I noticed the sovol probe made a rattling noise. I opened it up and found that the ferrite core around the spools has snapped in half. This is probably caused by the nozzle crash I had earlier.

 ![IMG_20241011_090037](https://canada1.discourse-cdn.com/flex030/uploads/sovolforum/original/2X/f/f9a59d361e25fa6a56c81927791df1772ca6b317.jpeg)

This explains the varying reading as the resonance of the coil was changing with the loose piece of ferrite moving around in the casing.

With the M12 probe the problem disappeared.  
I got in contact with sovol and they will send me a replacement.

Hi. I know it’s been a while since you posted this, but was hoping you could give some input. I recently made a bunch of changes to my SV08. I went mainline klipper, Eddy USB, and Mandala Rose Works bed. It’s working pretty well, though I wasn’t that impressed with Eddy…yeah, it’s fast, but I have to set Z offset way too often. Until someone releases an Idiot’s Guide To Eddy NG, I’m going back to an inductive probe.

Thing is, with the stock probe back in, I’m now seeing a whole bunch of retries, like you did. Mine’s sorta funny…seems only to affect the QGL, and not the pre-print bed mesh so much. I’ve edited my config to allow more retries, and so far it hasn’t stopped any jobs. But I suspected that in my fussing with the hardware, perhaps I messed up the probe, and it’s on its way out. So, I’ve ordered a couple M12 probes that should be here in the next day or so. I’ve already printed the mounts. I was wondering if you were still using them, and even if not, do you feel they worked better or worse than the stock probe?

With the new bed, I’m getting some great results, so I think I could be happy with the stock probe, especially if I could get rid of some of these retries! Thanks!

</div>

the M12 probe is working ok-ish. I do a manual PROBE\_CALIBRATE after a heat soak of about 5 minutes from time to time and that seems so work better than the automatic z calibration.

Do you use the Mandala bed with the magnet inserts ?

Since I think Eddy relies in the magnetic field that is conducted by the material it probes ([Eddy Current](https://en.wikipedia.org/wiki/Eddy_current) I can imagine that the magnets and steel screws produce a different result for the eddy sensor than the pei plate on aluminium alone. This could in my opinion create small differences in the probe offset.

Maybe try probing a mesh on areas that definitely have alumium as a backing and no steel or magnets near it.
