[my bad] Can't see the new toolchange behaviour

TypQxQ

[My fault, see below.]
I read that the b6 has a new toolchange behaviour: Important! After changing tool, RRF no longer moves the new tool head to the coordinates at which the old tool head was at when the Tn command was actioned.

But my toolchanges have not changed, the new tool still goes back to where the old one was.
Am I missing something?

All my config files and logs are updated at: https://github.com/TypQxQ/DuetBackup

You have the following in your TPost.g file in the custom directory:

; Restore for printing
G1 R2 X0 Y0 Z1     					; Restore prior position now accounting for new tool offset. X first to avoid certain collisions when near tool parking. 
G1 R2 Z0        					; Restore prior position now accounting for new tool offset

From the upgrade notes:

Important! After changing tool, RRF no longer moves the new tool head to the coordinates at which the old tool head was at when the Tn command was actioned. In most situations this should not matter, because GCode generators usually generate commands to move to the correct XYZ position after generating a Tn command. Usually, they restore XY before Z. However, Cura does it the other way round, which risks dragging the tool head across the print. Therefore when using Cura, or in any other situations in which you want to restore the old behaviour, we suggest you add command G1 R2 X0 Y0 Z2 Fxxx followed by G1 R2 Z0 Fxxx to the end of your tpost#.g files, if you don't already use those or similar commands.

So you are already compensating for this change.

@t3p3tony Thankyou, I missed that when checking the code for it....
