      With the 1.19 firmware installed, using volumetric extrusion, and firmware retraction.

      Config values as below :

      ; Firmware Retraction, called via G10
      M207 S1.2 F1800 T1500 Z0.2 ; Retract 1.2mm at 30mm/s (1800mm/min), unretract at 25mm/s (1500mm/min)

      Doing a print sliced in Cura 2.7.0

      My travel speed is set to 90mm/s
      Which it does when printing except when it does a Retraction.

      Combing is on so it doesn't retract or Z hop within a part, but when it moves to a second body it retracts and performs a Z hop, then travels at about 1/10 the speed.
      Like 9mm/s

      Any thoughts on what I have set wrong ?

      Edit:
      found the issue, its related to Cura.
      When Firmware retraction is turned on in Cura which has its own Z hop. there is also a section in Travel with "Z hop when retracted"
      With this checked it adds a Gcode to Z hop with a F300 command. so the whole travel move at retraction is F300 See below
      Turning off Z Hop when retracted fixes it

      G10
      G1 F300 Z78.25
      G0 X5.274 Y39.761 Z78.25
