Here is a test print for calibrating your hot-end temperature.
This is to see how your printing temperature influences stringing over spans and blobbing on fine detail.

Inspired by the temperature calibration test shown at:

I included the ipt. file if you'd like to change the text to different temperatures.

Printed on 0.2mm layer height.
In Repetier host I set the temperature (under "Manual Control") as the printer reached each new section.

You could also manually edit the G-code.
Find the layer on which the temperature should change and insert the "M104 Sxxx" command where "xxx"=the desired temperature
E.g. M104 S230 for 230ºC.

It seems the small overhangs are kinda tricky to get right, I tried increasing the wall thickness setting but still had the first layer of each dangle down.
