Tell Cura to over extrude on layer 1 through 20

[ITJake 0]

Is there any way of telling Cura that I want layers 1 through twenty at 130% extrusion? Layer 0 must be at 100% then switched to 130% @ layer 1 and print at 130% until layer 20, then change speed to 80% @ 100% flow rate until layer 30 where it can start running at it's normal speed of 100% @ 100% flow rate.

 

Thanks in advance.

Without a custom script you would need to do it manually.  M220 S100  would set the Feed Rate to 100% and M221 S100 would set the flow rate to 100%.  You can use the search function in Notepad to find the start of each layer you want to change Feed or Flow at and insert a line.

Search for "layer:1" (must have the colon)

Just below the  line ";layer:1" add:

M221 S130

Search for "layer:20" and just below that add:

M220 S80

M221 S100

Then at layer 30:

M220 S100

GregValiant, thanks for the info. I was thinking that's what would have to be done but wasn't sure of the code to insert. I was searching last night for the codes to use and just couldn't find them since there are so many sites that have them but either don't explain what the code is or say it may not work in the software your printer is using.

 

Thanks again.

Mostly there is Marlin and Reprap.  There are other firmwares but they are necessarily similar.

The Marlin GCODE is HERE.  The  RepRap site is easy to find as well.
