x0,y0 ls in my case the right, rear corner

thats going to be very confusing.
certainly because of that you got the offset of your probe wrong.

Frederik

@Veti should i change it ?

Frederik

@Veti this is my actual drive mapping and endstop config:

M569 P0.0 S0                                          ; physical drive 0.0 goes backwards
M569 P0.1 S0                                          ; physical drive 0.1 goes backwards
M569 P0.2 S0                                          ; physical drive 0.2 goes backwards
M569 P0.3 S0										  ; physical drive 0.3 goes backwards
M569 P0.4 S0										  ; physical drive 0.4 goes backwards
M569 P0.5 S1                                          ; physical drive 0.5 goes forwards
M584 X0.1 Y0.0 Z0.2:0.3:0.4 E0.5                      ; set drive mapping```

;Endstops
M574 X2 S1 P"!io1.in"                                 ; configure active-high endstop for high end on X via pin !io1.in
M574 Y1 S1 P"!io0.in"                                 ; configure active-high endstop for low end on Y via pin !io0.in
M574 Z2 S2                                            ; configure Z-probe endstop for low end on Z

Veti

can you set 0,0 in your slicer to be top right? i just checked in prusaslicer and 0,0 is bottom left

Frederik

@Veti i have to look. i used cura 4.8.0 at the moment. I didn´t want to spend money on simplyfy 3d bevor the new version 5 is released. Hopefully soon

Frederik

@Veti yes, its possible. you can set high or low endstop positions in advanced printer setttings

Veti

@Frederik
my recommendation is to not do it. why do you think that is better?

Frederik

what could be the cause of this message :

G28 Z
Error: Z probe already triggered at start of probing move
Error: Homing failed

i got this message on every 4th or 5th try to home z.

its a genuine bltouch

Veti

that sounds like a wiring probem

Frederik

@Veti i tought, perhaps its the standard and would be better for compatibility or troubleshoooting reasons...

Veti

@Frederik
no the standard is 0,0 is bottom left.

Frederik

@Veti ok , one moment i will check it with my multimeter... could it be a bad crimp ?

I could only mount the Endstop on the left side of my carriage and the Y Endstop is at the back

Hi,

The location of the end stop sensors do not determine where 0, 0 is located.

End stop sensors are used during homing, true, but they only "tell" the firmware the hardware is in a known location, which may be at the axis min, the axis max or somewhere else.

It is common to have 0, 0 at the left front corner of the bed. Another option is to have 0, 0 at the center of the bed - that is the what I do.

Frederick

Frederik

@fcwilt Ah ok, now i got it

Frederik

so, now to a new start... nozzle free again, probe working (was a light loose crimp pin on the black wire)

Frederik

ok ,looks good so far. i startet my first 20mm xyz test cube fingers crossed , i hope it will run through without clogging

Frederik

This is my very first successful Print:

It should be 20x20x20
And the actual dimensions are

X 20.10 MM WITH STEPS 160
Y 20.10 MM EITH STEPS 160
Z 20.40 MM WITH STEPS 400

Veti

you have not calibrated you e steps yet

Frederik

@Veti i forgot E 830

i dont know what you mean by that

here is a guide on how to calibration it
