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?
