M109 Command Not working

[NerdHerd704]

Hey All,
I recently upgraded my hot end temp sensor to a PT100 and ever since the printer will start without the extruder being fully heated.

The sensor is reading the correct temperature and the printer is otherwise working fine but it seems like it is totally ignoring the M109 command and beginning the print before the extruder reaches temperature. The only changes I made when I added the PT100 was the temperature table and the analog input pin the temperature is now being read through.

Any other ideas would be appreciated.

Thanks,
Andy
