This is a G-Code script for warming up your 3-D printer so you can print immediately when you want to print. My Thing-O-Matic only can build things from the SD card and can jog... not control the heaters.
1) Open Warmup.gcode in RepG.
2) Adjust Temperatures if you need to.
3) Build to File on your SD card. (s3g file)
4) Run the Warmup.s3g on your Thing O Matic or other RepG controlled robot when you want to warmup the extruder and heated bed.
I find it works fairly well. Just run it while you are waiting for Skeinforge to slice your print. :) That way when you actually get to printing it you don't have to wait for something else.
I find you can take the SD card out while the program is running since this program is so short. This allows you to put your object to print on the SD card while the printer is warming up.
