  • IDEX Gcode Separate Dual Extruders

    I've watched many of Dr. Vax's excellent videos but must have missed it if he did one on using GCode commands for dual extruder printers. In this case, a Tenlog DL3 Pro. Specifically, I'm trying to set up starting GCode so both the bed and both extruders will start moving to temp instead of waiting for one or the other.
    I'm using Prusaslicer 2.4. (Working great so far!)

    I found this on one of Chris's basement videos:
    Start Gcode:
    G21 ;metric values
    G90 ;absolute positioning
    M82 ;set extruder to absolute mode
    M107 ;start with the fan off
    M104 S[first_layer_temperature];set extruder temp & don't wait
    M140 S[first_layer_temperature];set Bed temp & don't wait
    M190 S[first_layer_temperature];wait for Bed temp
    M109 S[first_layer_temperature];wait for extruder temp
    G28 ;Move to min endstops
    G1 Z15.0 F9000 ;move the platform up 15mm
    M117 Printing...

    But, will this work for both extruders?
    Or do I have to insert the T0 and T1 in the M104 line?


    The end Gcode looks like this:
    M104 T0 S0 ;1st extruder heater off
    M104 T1 S0 ;2nd extruder heater off
    M140 S0 ;heated bed heater off
    G91 ;relative positioning
    G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure
    G1 Z+0.5 E-5 X-20 Y-20 F9000 ;move Z up a bit and retract filament even more
    G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way
    G0 Z+100 ;move Z up 100mm M84 ;steppers off (Get the extruders up away from the print
    G90 ;absolute positioning

    What I would do is:
    1. Insert the M140 line to start the bed heating
    2. Insert T0 on a line by itself
    3. Insert your temperature setting lines for the 1st extruder (no waiting)
    4. Insert T1 on a line by itself
    5. Insert your temperature setting lines for the 2nd extruder
    6. Insert any lines you want for waiting

      Yeah, it is the same as with tool changer systems. But you should ensure to use a T0 when you are done, so that the default tool head is active when a print is done and the slicers gcode gets gets inserted.

      At least the old version of Cura did not use a T command unless the print starts with T1, so T0 should be set at the end of the start GCode to get the right tool head all the time.

        Subbed for sure.

        I have a vested interest, hehe
        this is all I've done with mine of note, have not yet gotten it to talk to my laptop.

        I feel they did most of the dev work on Cura 4.4
        mine shipped with cura 4.8 on the sticky SD card.
        they a new looking link to a windows 4.9 cura profile on the website, and they have a buncha screengrabs off that profile, but going thru them,the dual stuff feels like it was either carried over, or gotten from another source.

          3dprint.rj, Meicalnissyen, is this a rebranded, somewhated modded JG Maker Artist D? They sure look a lot alike, albeit the extruders are different.

            as an afterthought, would writing the code as OEM did be part of that "eco" button mindset?

              the tenlog ? don't think so, but do not know.
              they have another name that gets mixed in, particularly when titan extruder gets in the search string 'hictop'

                the MOBO has 2209's with heatsinks so, cool.
                the red wire from main, to PS presses firmly against the cut end of extrusion so, not cool


                swings and roundabouts

                  Yeah, I'm surprised it could get UL approval. I would definitely be doing something about that myself.

                        LOL, that's funny. But what about people who don't have any Overture filament?
