Hi, I have installed Independent Z motors and endstop switches on my CoreXY and it is working well. But is there a way to use this setup and BL-Touch?
Endstop switch to tram the bed and BL-Touch to compensate for error on the build plate?

Thank you, I will try this.

Thank you for replying.
For now I am using manual leveling. Here are my files:

My first post; I'm doing things i can't, but trying to learn ....Total newbie

I have set up my CoreXY with independent Z motors and endstop switches using this guide:

https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches/

When I use "homeall" I get this message "!Error: G0/G1: insufficent axes homed"
But when i home x, y and z individually and then use homeall it is ok.
When I move x, y and z away from endstop, the same error occurs.
What am I missing?
BTW - It prints ok!
