so far i have tried everything but nothing works. Nozzl is still 2mm above build plate. @phaedrux suggested that my home configurations are faulty. is it because i removed my z axis trigger, or is there anything else wrong. config files seamed to be ok so far as i can tell. I have a ender 3 (not pro), duet 2 wifi and a og. BlTouch wiring are all correct as on the diagrams from the web.

Thanks in advance for response, cheers.

here is the config.g

well, for the start of an endless beginning here are my homing files.
homey.g homex.g homez.g homeall.g

Would be super helpful if someone could take a look and give some advice. since i'm working on this project with determination and frustration hand in hand, i'm not willing to give up on it any time soon

all is good, separate axis homing is now all good, guess i had to take a break from this ... but now i have to figure out how the homeall.g should look like for my particular printer.

at the moment i'm using anet a8 motors except on the x axis i have a wantai motor , because i'm cheap, and the Psu is 12 volt. both z axis motors have endstop switches. Right now i'm fooling around with macros for homing x and y axis to prepare the code for actual homing commands.
The config.g looks like this

Hi everybody.

I'm working on a 3d printer, it dual z axis with endstop micro switches, X and Y axis are hopefully sensorless... I on the other hand have no background in programing what so ever. The thing is i'm having hard time homing my Y and X axis from a random position. Can please someone take a look at my nonsense and push me at the right direction.

So thanks to all of you i finaly got my work horse up and running... feels great to be back in busyness. Phaedrux, you gave me that link, well i did as you and in the duet page was told... didn't doo anything. so i installed Duet Web Control 3.1.1. works great and looks better than the old version...

Thanks for the incredible expeiriense of a great community support.

i us the same document to calibrate my bl touch

its a temporary repai >D the tip of bl touch has broken off. and i have mutch greater problem to deal with... doesn't have the tool tip have to be just above the built plate... cuz when i did the z probe callibration, insted of thickness of the paper witch was about 0. something. it showed me after G30 S-1 2.15 mm wtf?
