but now both X and Y homing are in the wrong directions
the direction of homing is the the home[xyzall].g
I've corrected the thermistor but now it appearsa the following error after a while:
what did you correct it with?
create the filament folder on the sd card on your computer
The thermistor I choose is:
M308 S0 P"bedtemp" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin bedtempshould the filament folder be created empty?

M308 S0 P"bedtemp" Y"thermistor" T100000 B4092 ; configure sensor 0 as thermistor on pin bedtemp
that change would not cause the problem with the rise in temperature.
should the filament folder be created empty?
yes

yes
so what's the problem for the temperature? In console I see the bed temperature rises but after few seconds the error appears

@Veti excellent, all solved!!!

going back to the lead scew. what kind of leadscrew is it?
t8x2?

they are the original trapezoidal X5S lead screws I think they are T8 and I think the pitch is 2

The it should be 1600. There is a steps calculator at the Prusa website
-
-
so 1600 with a 3:1 ratio would be 4800

exactly but with this esteps it move much more mm
-
@the_dragonlord
with 8000 it would move even more

of course....when I'll complete all the inital set ups I'll print the calibration cube and then I'll see....for now I'm struggling with the BLTouch

@the_dragonlord said in Worng homing on a CoreXY and totally wrong step/mm:
trapezoidal X5S
according to marlin its a t8x8 4 start
so 400x3 = 1200
try that
-
And Double check the Ratio of 1:3
-
@Veti I don't understand anything.....Now the X and Y home are correct but if I send G1 X10 the carriage moves in the wrong way........................WHYYYY???

M574 X2 S1 P"xstop" ; configure active-high endstop for high end on X via pin xstop
M574 Y2 S1 P"ystop" ; configure active-high endstop for high end on Y via pin ystopyour configuration says the endstops are at the maximum.
you want X1 and Y1

UUUUUUUUUUUUUUUUUHH STUPID ME!!! I thought active-high meant that the tension value when triggered was high
