Chekhov has a good dialog driven solution. Below is an alternate solution if you prefer to use a single profile for printing.
Solution:
If you are using marlin firmware on your printer there is an M-Code command M220.
1) Open up the g-code file in a text editor (I use notepad++)
2) Using find and replace, search for "; layer 1,"
3) Replace with "M220 S30 ; layer 1," This will slow the printer down to 30% of normal speed.
4) Using find and replace search for "; layer 2,"
5) Replace with "M220 S100 ; layer 2," This sets the printer to 100% speed for the rest of the layers.
Simplify3d allows a layer change script but will not allow unique layer scripts which is why we have to manually insert the M220 command.
To save time I've recorded a macro in Notepad++ that automates this code manipulation. Making the macro is as simple as MACRO>START RECORDING, go through the 5 steps listed above, MACRO>STOP RECORDING, then MACRO>SAVE CURRENT RECORDED MACRO.
I realize this is an old thread but I've been having this problem more recently since building a delta printer. Both my XY printers do not have a problem with printing a brim since they move about 40mm/s. The delta can produce high quality prints comfortably at 80mm/s to 120mm/s. At these speeds, the first layer does not bond well with
