Printer is not heating

I finally got my printer running, did a test print with an file I printed before and it went fine.
Then I tried to print a newly sliced image and the bed and nozzle temperatures remained around room temperature and no printing happened after a long wait.

The printer preheats to any temperature, and prints old gcode,  so I am guessing it is a Cura problem.

I likely upgraded Cura since last printing. So I upgraded to Cura 4.0, told it to install without retaining old settings.

Same problem.  Tried more variations on this. 

So I started to read up on the basics of gCode and how to use Repetier Host (questions here for Wednesday).

Doing a line by line comparison of the first parts of the gCode, to where it supposed to start printingl seems to be identical between the file that prints or does not print unless there is some punctuation type thing I missed.

The nozzle never does the initial dance to the corner. Everything just sits there like it was with temperature varying only a couple degrees.

Any idea where to start figuring this out? 

The file with MSMV2E3D_PRINTS_Filament_Clip.gcode in it is older and prints - the other file is identical file that was resliced with what seems to be same settings and does not print.

Hi Karen,

There is a M25 (Pause) gcode at the beginning of the file.  Try removing that and see what happens.


; -- Pause at height (5.00 mm) --
M25        ; Pauses the print and waits for the user to resume it
;Generated with Cura_SteamEngine 4.0.0

Bill, you beat me to it!!!  That's probably it since it's right before the temp settings so it never heats up either.
