Thank you guys, you find the error. With more than 0%, it works. Works with 1 seconde time out but I will set as you describe.

Have a good day

There is no error reported with homeall.g, and no error reported with homex,y,z since I add the "H2".
When I send G28, the printer begin the homing by moving the X axis twice, then the Y axis twice, then Z axis twice, as written in the GCode. The endstop switches work well. But after the procedure, the printer remains not homed. The X, Y and Z buttons in the console of DWC remain orange.

If I try to force the homing by setting the known position with a G92 code, the buttons move to blue color. If I move the axis after that, the printer is de-homed again.

@droftarts the homeall.g does not work too.

homex.g

; increase Z
G91 ; relative positioning
G1 H2 Z5 ; move Z relative to current position to avoid dragging nozzle over the bed
G90 ; absolute positioning

; home X
var maxTravel = move.axes[0].max - move.axes[0].min + 5 ; calculate how far X can travel plus 5mm
G1 H1 X{-var.maxTravel} F3000 ; coarse home in the -X direction
G1 X5 F6000 ; move back 5mm
G1 H1 X{-var.maxTravel} F300 ; fine home in the -X direction

; decrease Z again
G91 ; relative positioning
G1 H2 Z-5 F6000 ; move Z relative to current position
G90 ; absolute positioning

homey.g

; increase Z
G91 ; relative positioning
G1 H2 Z5 ; move Z relative to current position to avoid dragging nozzle over the bed
G90 ; absolute positioning

; home Y
var maxTravel = move.axes[1].max - move.axes[1].min + 5 ; calculate how far Y can travel plus 5mm
G1 H1 Y{-var.maxTravel} F3000 ; coarse home in the -Y direction
G1 Y5 F6000 ; move back 5mm
G1 H1 Y{-var.maxTravel} F300 ; fine home in the -Y direction

; decrease Z again
G91 ; relative positioning
G1 H2 Z-5 F6000 ; move Z relative to current position
G90 ; absolute positioning

@droftarts It's done and does not solve the problem

I changed homex.g, homey.g et homez.g and put H2.

Now an independent homing can be almost carried out. The program does not store the procedure and the machine stops moving at the line:

G1 Z-5 F6000 ; move Z relative to current position

due to insufficient axes homed. Its very weird.

@jay_s_uk said in Homing issue on Duet2:

post your separate homing files and which axis when homed being independently actually causes the error

Each axis causes an error when I try to homing it. When I do a home all, the procedure is completed to the end (the 3 axes go to the end of their travel 2x) but the program doesn't want to store the homing.

Hello everybody,

I've modified an existing printer. Everything works except the homing. When I do a homing, the machine executes it correctly. The X and Y axis switches and the Z axis probe detect the end of travel correctly. However, the program is unable to record or transmit the homing and so the machine remains unhomed. I can't homing independently because there's a "Error: in file macro line 8: G1: insufficient axes homed" message. I can't find the problem because my "homeall.g", "homex.g", "homey.g" and "config.g" codes seem to be correct.

It's a Duet2 Ethernet card, which I've configured using the reprap tool. The printer is running RepRap and DWC 3.5.2.

Thank you for our help.
