Printing Wood Grain: Heating Failed

Humm, I used to be able to print wood graining with wood.py but I just can’t get it to work without the printer (Taz 6 w/ Merlin) refusing to start with a Heating failed message. It seems in the past that I could print and get great results even if the Heating failed message showed on Taz. Suggestions?

(from wood.py:)

Name: Wood

Info: Vary the print temperature troughout the print to create wood rings with some printing material such as the LayWoo. The higher the temperature, the darker the print.

My usage:

$ python wood.py --min 185 --max 280 -f new-lamp-top2.gcode

How does the gcode file look after you run the post-processing script?
