Solved Please Help.. Homing Z

[TOFUATSU]

I am almost don building my first printer. I have a CoreXY. I am using a Duet WiFi (original), DC42 ir sensor. I have the X and Y moving correctly and finding home.

no matter if I use the home all or do one axis at a time. I always get the same G28 Error: G0/G1: insufficient axes homed.

the Y endstop is located at the front left. the x endstop is on the left of the x carriage. the z probe is right by the hotend.

here is my config file

@tofuatsu You need to ads a S1 to all axis moves that are done before homing. For example: G1 Z5 S1 F3000

@stephen6309

Please forgive me.. I am really new. I looked into it.. are you talking about adding S1 command in the homeall.g file? I think they are present. This is my file

@tofuatsu I finally got around to upgrading my corexy with the presale DuetWifi from 1.18 to 2.02RC6 and had to change my homing files.

@stephen6309 hummm I copy and pasted your homeall file... it still fails when it tries to home the bed. to does move differently.

Check that there are no commands in your deployprobe.g and retractprobe.g files, unless you are using a BLTouch - in which case, check that they are the correct commands.

@dc42 Thank you so much!!! That was it!!
