Change speed at layer not working?

[paulf123b]

Hi. Thanks for this awesome macro set.

This specific macro is not working for me; I've not tested any of the other during print ones yet.

The trigger happens but no change to actual print speed occurs. I manually issue the same command M220 S300 and it kicks in.

Thanks for any help!

3:55 AM
layer 3:

• M220 S300
  3:55 AM
  speed_at_layer SPEED=300 LAYER=3

It sounds like the layer change gcode isn't configured properly for your slicer.
