Initial hotend temperature set to 0

Marlin is setting the initial hot end temperature to 0. This is on a UMO with official HBK. Print was made from an SD card on an Ulticontroller. The firmware is the default from Cura 15.01-RC6.

Sorry for cross-posting, but didn't get any replies in the Marlin section.

    avi,

    Which line are you seing it?

    The only M109 line I see set the temp to 192. The T0 is to specify the target.

     

    1. [*]M109 T0 S192.000000

     

     

    I'm no expert in gcode so I probably don't see the one you refer to.

    When I ran this code on my UMO, (code was generated in Cura) the hot end temperature was set to 0 and the machine didn't do anything until I manually set the temperature. After manually setting the temperature, the machine heated up and ran like normal.

    I didn't see anything wrong with the code either, so I really don't have a clue what the problem is. It started when I last updated the firmware, so I am guessing it is a Marlin problem, though I updated Cura at the same time. I first had the problem right after updating to install a graphical controller. After noticing the problem, I flashed back to the latest stock firmware, but the problem persisted.

    I guess it waits for the heated bed.

    I saw this as well: first the bed is warming up and the nozzle temp is set to 0, when a bed temp is reached the nozzle temp changes to the set temp.

    are you using the basic printer window or the pronterface one? I've always needed to set the temperature for both the bed and nozzle using pronterface, never used the basic window when using cura.

    I print from SD Card.

    M190 sets the bed target temperature and waits until it reaches that temp.

    There are others that just set the temp but do not wait. M104 for extruder, M140 for the bed.

    So you can do things like (not sure about the G4 syntax):

    ;start heating the bed

    M140 S65.000000

    ; wait 60 secs to give the bed a headstart

    G4 S60

    ; Start heating the extruder

    M104 T0 S190

    ; wait for the bed to reach temp

    M190 S65.000000

    ; Wait for the extruder to reach temp

    M109 T0 S192.000000
