Worng homing on a CoreXY and totally wrong step/mm

@the_dragonlord said in Worng homing on a CoreXY and totally wrong step/mm:
I use 8000 because I have a single stepper for the Z and both the Z rods are syncronized with bigger pulleys wich leads to a 1/3 ratio
that would mean a leadscrew of 2666. which is unusual as well.

No way to make it work....now the G1 H2 X10 F3000 moves the diagonal correctly but now both X and Y homing are in the wrong directions
I've corrected the thermistor but now it appearsa the following error after a while:
And I can't test the extruder beacuse I see this error during startup:

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

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???
