I have an odd occurrence. My prints will start instantly and not wait for the temperature controller to stabilize. I have that checked for both the extruder and bed. I've closed and rebooted to see if it was a stray piece of code but not the case. I have to manually heat and make sure that all temps are reached or I'll be doing a cold extrude. I noticed it today when I heard my filament grinding and looked to see that my extruder temp was 120C. Even though I have "prevent cold extrude" in my firmware set to 175C, S3D went ahead and tried to start the print.

Anyone else seeing this? I'm using the latest update.

Rob, open up the gcode file you have trouble with in a text editor. In the beginning somewhere see if you can find an M109 Sxxx. Xxx will be the target temp. This should be there if the box is checked. It tells your firmware to wait. If it is there then something isnt right on the firmware side. If its missing then s3d is at fault and not putting it in for a reason. The prevent cold extrude does exactly and only that. You can always still start a print if its not to temp. Your extruder motor will just not extrude. This is set in the firmware only and has nothing to do with how s3d starts your print.
