I need help with extruded rate in Grasshopper

Sorry for my bad English. I’m new to Grasshopper and I made a pattern for 3D printing, but I got some problems with the Gcode, especially, the Extrude rate. I want the extrude rate to be 0.2mm but I thought that the 0.2 mm length of each segment will be added to the previous length to obtain the series: 0, 0.2, 0.4, 0.8, 0.12,…but it is not. It just keeps the E 0.2 from the beginning to the end. Please help me fix this.
I attached my file below.
Thank you so much

Your source geometry is not internalized so this is a wild guess.

The extrude rate is exactly set to 0.2 in your Concatenate component, so maybe you need a Series there too ?
