have to adjust living Z on each printed object

hi guys,

since the last two firmware update a got problem with my printer.

For each printed object i have to "Live adjust Z".
My first print is ok (after firmware update), my second print (not necessary on the same day) i have to "live adjust Z", arround -0.900mm , my third print ... have to add again -0.900... (-1,800mm) and again and again and again on each printing stuff... it's endless. Reset, reboot, etc... nothing fix this bug.

firmware 3.2.3

Hi, You seem to have misplaced your question. MK2 is old and definitely not supported by PrusaLink and Connect, at this moment and probably never. I don't really know the printer and so can't help :/ sorry

due the price of a prusa printer, can we really use the word "old" ...

I am a PrusaLink dev, I do not and did not own an MK2 ever. This is not a unique occurrence in the company. From this point of view, your printer is too old for me to conceivably help you. Please post in the appropriate forum category: https://forum.prusa3d.com/forum/english-forum-original-prusa-i3-mk2-s/ or contact the official support using [email protected] we appreciate you bought the printer, without its success, the company might have not hired us, so thank you.

[...] For each printed object i have to "Live adjust Z".

As @Tojik notes, you're posting to a section that is not focused on the Mk2. You're a lot more likely to get help by posting to the Mk2S group.

Have you tried rolling back to the previous working firmware version to verify it's not the sensor?  I have another printer that exhibited similar behavior. The Z offset would change by a fixed amount every print. In my case, it's a failed sensor. In your case, it sounds like the problem only started after a firmware update. Ask in one of the Mk2 related groups about any issues related to PINDA sensors. You might need to replace your sensor or make other adjustments.
