I want printer to slow down when it reaches the top to do lettering? How?
I am doing to printing and when I get to the top I have lettering. The PLA is acceptable but when I do the same thing with PETG it gets a bit stringy. I have lowered the temp to 204c and it seems to help. I was wondering if there was a way to slow down the printer when it gets to that part. I am using Slic3R Prusa. I can download Cura slicer if that will help.
Thanks.
Any other suggestions are welcome. I am using MakerGeeks PLA and PETG. Both print well but when I get to the lettering the PETG seems to get messed up.
Thank You again.

I was trying to figure that out in Slic3r. Have not figured it out yet. 7 hour print so don't know if I can be here when it gets to that part of the print.

M220 sets the feedrate by g-code. You could just edit the Gcode manually at the proper place to automate the speed switch. Slic3r doesn't insert layer comments, so you have to find the appropriate G1 Z movement yourself. Let's say you want to slow the printer to 80% at Z=100mm. Open the G-code and search for "G1 Z100" then add the appropriate M220 command.
M220 S80
G1 Z100.150 F7800.000

You can make slic3r to insert layer comments.
Printer Settings -> Custom G-Code -> Before Layer change G-Code
Look at the tooltip help, there is [layer_z] and [layer_num] available

Actually, you can use conditional code processing:
{if layer_num==1234}M220 S80{endif}
