Thermocouple and M109 - Printer starts without waiting for temp
I just added an ADAFruit breakout thermocouple to my system and updated my config using the website... downloaded the full firmware package of 0.92 with the new config on Saturday night. The thermocouple is on pin A3 on a ramps 1.4 board.
I'm getting good temperature readings for the extruder and everything seems to be working right, except that when I start a print with the following GCODE:
M107
G28; home all axes
G1 Z5; Raise 5
M109 S200
G21 ; set units to millimeters
G90 ; use absolute coordinates
M82 ; use absolute distances for extrusion
G92 E0
...
The printer homes, Goes to Z5, turns on the heater, and immediately starts the print. It's not waiting for temperature before starting. Is there another setting somewhere that I need to use to make it wait on the thermocouple temp? This wasn't happening when I was using a thermistor plugged into the normal pins.
Comments
M104 S0 ; turn off temperature
G28; home X Y and Z axis
M84 ; disable motors
The printer's dump area is defined as 0,0,400 (I have about 409mm in the Z axis) in repetier host.
I did see a message go by in the log that said something like "resending G1 Z10"... it said more than that, but I didn't copy it down. I'll grab it after the next print.
