Unable to use second extruder

rmagnusrmagnus
in Repetier-Host
Hello all

I have a XYZ davinci 2 duo that was working well using the 2 extruders with the stock firmware. I successfully printed 2 color parts several times.

Then I reflashed it and now I am using repetier host for windows version 1.5.4 with slic3r 1.2.9

On repetier Host I see two assignable extruders where I can assign the objects I load to the extruder I want to use.

Then I slice and print but the da vinci only heats and uses extruder one even if I assigned extruder 2 before slicing

On the da vinci I can clean, load, anything on extruder 2 so it is recognized by the da vinci repetier firmware and by repetier host but it just does not print using extruder 2

Please advice.

THANK YOU

Rod Magnus

    Pleas update host. There was a problem with slic3r not using the extruder selected but always starting at extruder 1. This has been fixed since 1.5.5 I think, so that might be th eproblem.

    CuraEngine still starts with extruder 1 and can not use only extruder 2.

    Will this fixed with cura? I was able to run it one time with extruder 2 only, however it was possible :-/
    Is this a problem of cura or Repetier Host?
    I don't want to change the filament every time I want to use the other color :-(
    Is there a work around e.g. edit G-Code simply before starting printing?

    Thank you.

    CuraEngine want the files as stl and first file is T0. So using only last extruder is the problem with this system. You could have a configuration with T1 in start gcode so it still uses second extruder instead.

    I have the same issue with my flashed Duo, Host keeps faulting on connect, pop up reads "Check API" Win 10 on an HP Inspiron. Since I own an MK3s I am proficient in Prusa Slicer so my hands are tied. I select Ext 2 on the slider and #2 never preheats or switches at the selected layer. When I try the single Ext change filament by pausing print and loading diff color the first layer of second color has a layer shift making print off centered. Cura gives me a brain concussion trying learn (I'm 72 yrs old btw) What am I missing with connecting to Host?

    I have never seen a message "Check API" and even just searched host sources and it does not contain that message. So I wonder who is making the popup and where the content comes from. Maybe if you can show the complete message I can make sense out of it. Guess it comes somehow from serial driver when connection gets started since it not in our code. In that case I have no real idea what they want to say. 
    Have you ensured no one else is using the serial port? Also that normally returns a different message.

    After much reading over "How to Connect" I uninstalled Host & Server app and started from scratch, was able to connect and see printer but the learning curve is a little more then I expected. This too I will over come!
