well, in that case you should tell it sooner :-). In that time I didn't even know whether it is issue just on my printer (and few other owners) or whether it is general issue everyone fighting against. You came just with "my printer(s) doesn't do that" (which was anything but helpful).
I mean, yeah, you sent something, but it wasn't an explanation of it, just some setting, some more, some less suspicious (i'd even call it "snake oil", but it sound too harsh since it helped, although in different way - I've never even tried to print 1st layer so fast as you before, so it wasn't completely useless. And for this suggestion, I thank you. It just wasn't solution for the issue, though).

and... how it helps to solve the issue with gradually expanding nozzle/hotend making the 1st layer lower and lower?
Since I already found the biggest thermal expansion, the hotend (and/or its nozzle). Within first 10-15 minutes of printing it makes nozzle lower by almost 0.1mm* (at least I believe it is the main issue, 0.1mm difference is more than enough to make 1st layer ... weird).
*) 0.07mm to be precise. I didn't recheck difference between nozzles, but somehow it seems the diamond CHT-ish nozzle expands as twice as much as e.g. tungsten nozzle which I measured expansion by 0.04mm (I want to recheck again, since it seems to me too big difference for the nozzle alone. Just not soon, I have other priorities at this moment)

It can be quite easily measured if you have Beacon (contact) using something like this:
https://github.com/kmarty/kmarty-klipper_config_km_addons/blob/master/CHECK_THERMAL_EXPANSION.cfg
(it's based on RatOS v2.1.
BEACON_CALIBRATE_NOZZLE_TEMP_OFFSET except it doesn't make any changes, just prints results and it uses hotend temperature defined by you. Results is list of Z positions where nozzle "found" bed (so you have to subtract first measurement which is at the room temperature), each by one minute apart).81 replies

Nice.
So, I should have made own post anyway since my issue is not by bed itself (heatsoaking of bed doesn't change it at all) and height difference in my case is about 0.1mm where I already measured that Rapido2 UHF hotend with diamond CHT(-ish) nozzle can easily expand by about 0.07mm in first 10-15minutes of printing. So in my case it is probably just to find how to easily deal with the fact that is happening.

also the adapter cable is probably good to check (you have to have one since original connector desn't fit on EBB).
But if you have inifinite resistance even on blue wires, then it's likely the RTD is really bad.

better to double check, especially if you have thick test leads on multimeter and it's hard to reach pins on JST-XH cable connector. But there was a suspicion, so...

Just to be sure, in case it isn't obvious: The connector has to be disconnected from EBB for proper measurement (we don't want to measure parallel resistances and/or voltage from EBB)

and if you measure anything out of range about 1040 - 1160 ohms (still at room temperature, this range is for temperatures between 10 - 40 °C), do the same at the (original) connector directly on blue wires

can you measure resistance od PT1000 at the connector which is directly for EBB?
(it should have resistance about 1100ohm at room temperature)

perfect 🙂
(you wouldn't be first who got different model than ordered (especially on Amazon or Aliexpress), hence the question)

Nice pictures, what about hotend you really own?
(the one with PT1000 should have blue wires with label "PT1000")

Is it really Rapido Plus (i.e. with PT1000), not Rapido "nonPlus" (i.e. with Semitec 104NT-4-R025H42G)?

Here is the example of start in the middle of the bed (the lowest possible point when X-gantry is warping) and yet, the lowest point is at the end of print, basically at Xmin and Ymin.

Hmm, but my bed mesh doesn't change much between cold and hot. It remains moreless the same. (perhaps because it is 300 only).
Also I don't think it solves the issue when print starts in the middle of bed and end at the edge of the X axis and yet, the ending of printing is lower than the beginning.
As I wrote, the thermal warping of X-gantry keeps Xmin and Xmax at the same height and middle of X axis goes lower.
But here it gradually goes lower regardless of X (or Y) position.

Yeah, I think the thermal expansion is root of this too. But which one?
I believe there's no much options - it's either hotend, leadscrews or X-gantry. Everything else would cause moving away from the bed when expanding rather than moving closer. Or did I missed some part?
It could be all of these together, of course (where on account of X-gantry should be only "bowl" effect, with maximum on Xmax/2)

In terms of hiding/covering the issue, the wider line width of infill and higher layer height of the 1st layer seems to be surprisingly effective.
(it doesn't remove the issue, but it hides it enough not to be disturbing issue. Yet, the issue is still there)

(BTW you seem to have the same issue, just not so horribly pronounced as on my printer)
