New version of the Extruder temperature column for PLA.

"After slicing this 10cm high column change the extruder temperature in the GCODE file after 10mm travel in the Z axis. Examine the print and determine the best extruder temperature for the filament you are currently using. The printed columns can be stored and used as reminders if the same filament is used in the future."

Simply add:
M104 S210 ; e.g. set temperature 210'C
Before G1 Zxx command in G-CODE file.
