IDEX Homing Issues

Ray11

I am using Duet 3 on RRF 3. When I select T0 and used G28, the finished position is X-30 and U320 which is the value I want. However, when I select T1 and use G28, the final position is X30 U30 which will crash the machine. The goal is to set the position to X320 and U320 when G28 is used with T1 selected.
I don't want to add a T0 in the homeall.g because this will turn off the heater at T1
Here are my printer dimensions:

; Axis Limits
M208 X-30 U30 Y0 Z0 S1                                ; set axis minima
M208 X260 U320 Y200 Z180 S0                          ; set axis maxima

Here is the homex.g

Here is the intended position, when I select T0 then G28:

However, when I select T1 and then G28:

In this case, although the U axis is at 320mm, the firmware thinks it is at 30.

Did you resolve this?

The G92 commands in your homeall.g file are not needed and should be removed.

Hi, I later found out that it was in my config.g file while I configured the end-stop setting wrong. The U axis endstop is set to minimum where in reality it should be homing to the maximum. Thanks for the follow-up.
