      Hi everyone!

      I have just upgraded my firmware from RRF 3.0 to 3.1.1 and found out that there is a strange movement in the tfreex files. It moves upwards after the last G1 Z-2 command in the tfreex.files.

      tpre0.g

      M400

      G91
      G1 Z2
      G90

      G1 X-30 F12000
      G1 X-39.5 F1000
      G4 P300
      M280 P0 S155
      G4 P300
      G1 X-30 F12000

      ;G91 ; commented out, the user Z coordinate is restored immediately
      ;G1 Z-2
      ;G90

      and this is the tfree0.g

      G91
      G1 Z2
      G90

      G53 G1 X-30 F12000
      G53 G1 X-39.5 F1000
      G4 P300
      M280 P0 S60
      G4 P300
      G53 G1 X-30 F12000

      G91
      G1 Z-2
      G90

      I look forward to your help. Thanks!

        I've also tried with a M400 command but it did not help me.

          Is it cancelling the Z offset of the tool being freed?

              @dc42 I think yes. The Z offset is 0.89 mm. This is the code in the macro file:

              G10 P0 X-32.85 Y-2 Z0.89 L1

                @dc42 it also happens to the tprex.g files, but it moves downwards after the last G1 Z-2 command instead of upwards. Is it because of the Z offset that being applied and cancelled after a tool change?
