Temperature issue after upgrade MK4 to MK4S
I upgraded from MK4 to MK4S two days ago.
In print settings i changed to "0.20mm SPEED @MK4S HF0.4".
Now i see the behaviour that before the print starts the nozzle heats up to 173°C/170°C (which is too high), then
comes the line the printer draws in left corner to fill the nozzle, and
to start the print, the temperature goes up to 233°C/230° (again too hot).
During the print nozzle temperature goes down to 216°C/230°C and print fails.
When using old printer settings temperature goes down 225°C/230°C and then recovers to 233°C.
Any ideas?

Are you trying to set a specific temperature in the manual controls? Is the temperature being maintained?

Not 100% sure what you mean by "trying to set a specific temperature in the manual controls? Is the temperature being maintained?",
but i'm using Prusa Slicer (2.9.4) and in there Prusa Connect.
I load the STL file and select "Slice now", followed by "Send to Connect". I always use first option so that print starts immediately.
Neither i change manually the temperature nor do any other manipulations.

But it doesn't ask you for any printing! He asks if it is possible to set a specific temperature in the manual temperature setting mode of the heating block and how the printer maintains it! In addition, check whether you have a silicone cover on the heating block and whether it is also selected in the printer settings!

Exactly, i ask to test directly on MK4S 🙂
RE: Temperature issue after upgrade MK4 to MK4S
Sorry, then i misread your answer, @Laban.
I don't have the Silicone sock on, and it is not selected either.
Also, i wonder, for which reason the temperature drops in one profile, but stays more up in the other profile.
How to perform this test with manual set temperature?

PS:
i tried once more, and this time, as soon as filament has been pushed out of nozzle right at the beginning,
before printer started to print the object, i selected "Anpassen" (Adjust in english, most left menu item), and then set nozzle temperature to 231°C (as 230°C) already was set by code.
After couple seconds temperature dropped to 216°C .
When printer is idle, and in main menu i select the left option in lower line of menu, then temperature -> nozzle and set it to 230°C,
temperature goes up to 233°C, blinks couple times, and then goes down to 228°C, recovers and stays at 230°C.
With fan speed set to 50%, temp drops to 227°C for couple seconds, then heating starts and temp goes back and stays at 230°C.
Fan speed to 100%, temp drops to 229°C, and recovers after couple seconds.
Fan speed down to 0%, temp goes up to 234°C, and after less than 15 seconds down to 230°C.
The complete test now ran for almost half an hour, and nothing seen like during the print.
Is there a (b)gcode simulator that runs the code and shows, what the instructions are?
I tried to translate the bgcode into ASCII gcode, but it is still hard to read it and easy to miss something,
especially when reading gcode for the first time.

PPS:
I tried to upload both, working and non-working bcode files, but seem that this is not supported in this forum.

And, one more information;
the printer keeps the temperature for the first layer, and
as soon as it starts printing the 2nd layer, temperature goes down.
