locking in print speed

[peopoly]

hi guys,

I am trying to set first layer print speed to be 5mm/s and the later layers print speed to 85mm/s. This is my set up screen:


My gode shows a first layer of speed 99mm/s and later layers has a speed close to 150mm/s.
Gcode:

Any suggestions?

There's a few reasons for this; need to determine which one...

Can you please upload your profile Project/Save Project As, zip up the project file and attach it to a post.

Thanks.

OK, no need for the project file, loaded from G-code.

First problem is that the layer thickness is greater than the extrusion width.

You have a minimum extrusion volume of 1mm^3/sec which will override any speed settings.

EDIT: basically, you have fixed your extrusion speed by setting the Min and Max flow volumes to the same value...
