So … z-offset calibration drift with the factory inductive sensor is sometimes a little … unpredictable. So I’ve been looking for alternatives. However, for every method I have come across, e.g. Eddy, Beacon, etc there also seem to be challenges and imperfections. So … after watching many YouTubes … I have decided that simple is best for now. And that’s to do it manually. So … in case it helps anyone else … here’s my workflow.
Turn machine on.
Home All
Set bed temp to whatever is required by the print to be done
Set nozzle temp to whatever is required by the print to be done
Leave to soak for 10-15 mins
Quad Gantry Level
Use the Mainsail console to do a ‘probe_calibrate’ … adjust until a piece of paper under the nozzle experiences resistance.
Use the Mainsail console to enter the ‘save config’ command.
Wait for the restart.
Kick off your print.
It’s the best I’ve come up with so far anyway …
Yea the stock SV08 inductive probe is absolutely awful. Fot me it drifts up and down up tp 0.5mm which is not a matter of first layer quality but a matter of destroying the build plate, the nozzle and probably even the hotend. #rant
Which is even more disappointing given that I get no issues with my SV07 inductive probe - it just works perfectly, or at least within the range that I don’t even notice any variation.
It’s terrible that we should have to pay good money and then need to mess around like this. I’ve never know such an inexact and unreliable piece of kit.
Thanks for your ideas, I may try them if I can summon up the energy to fight with this thing for yet another day!

This is an interesting concept … and one I intend to explore. Thanks ever so. As others say … this is a disappointing situation … but it is what it is … and if there’s a ‘reasonable’ workaround … then at least we have a good starting point. My Creality CR10 has a clicky … and never had a single problem with that.
It’s a bad situation when we are left to sort out this stuff for ourselves. Thank heavens that Sovol don’t make cars or aeroplanes.
I’m wondering if anyone has tried using a BLTouch for these machines? I’d be surprised if no one has tried. I’ve not found anything on the dreaded “MeTube” about this, but I know the BLTouch was a nice device in my Ender 3 days.

In my opinion you should not expect a flawless product for this price, or expect not having to tinker with it a little like other (way more expensive) brands also need some tinkering before everything works like it should.
Out-of-the-box experience also varies with the users expectancy and experience level
It’s easy to complain about everything you find and expect sovol to solve it for you, or maybe you could fix it yourself and share the knowledge on this forum and/or other platforms
I mean, have you noticed how many improved or replacements parts there are for Bambulabs printers ? That shouldn’t be necessary either in that price range right ?
Even the just released and waayyyyyy more expensive new one from Bambu has it’s flaws according to clough42
