How to modify the Marlin Firmware for ceramic 3D printer!

Hi Everybody;

I use the RAMPS 1.4, the Marlin Firmware and the Pronterface for my ceramic 3d printer. I don't need any thermistor, so i have tried my ceramic 3d printer without thermistor. Every axis worked but Extruder didn't work. I tried, to modify configration.h but i couldn't solve the problem. Everything was fine on the Pronterface. When i click on extrude 5mm in pronterface it thinks its extruding but isn't. How can i solve this problem?

Look for the following in your Configuration.h in your Marlin firmware:

#define PREVENT_DANGEROUS_EXTRUDE

Just comment that out (put two /'s at the start) like so:

//#define PREVENT_DANGEROUS_EXTRUDE

Save, upload to the board, and you should be sorted.

Thanks for your help, i comment out that line but it didn't work. I couldn't turn the stepping motor of extruder.
Do you have any idea?
