    Qidi Tech 1 Simplify 3D Startup Script

    In Simplify 3D when you select the Flashforge Creator Pro profile the default startup script creates a blob of plastic on the right side of the build platform. If you replace the starting scripts with these it will extrude a line of plastic along the front of the build platform to make sure the extruder is properly primed.

    This script was buried in the massive Qidi Tech thread, I thought it would be easier to reference if we made it its own thread.

    Paste this under the Left Extruder startup script
    Code:

    I just updated the scripts to change the default VRefs to 80 instead of 127.

    Changed this line:
    G130 X127 Y127 Z40 A127 B127 ; Default stepper Vrefs
    To This:
    G130 X80 Y80 Z40 A80 B80 ; Default stepper Vrefs
    Feel free to experiment with the values. Recommended values are between 60-80. By lowering these values you decrease the power to the stepper motor which helps with heat and may make your steppers last longer. If you lower the values too low the steppers will start to skip. For more info see discussion starting here:
    http://3dprintboard.com/showthread.p...ll=1#post88762

    Alternatively you could change the VREFs in the EEPROM using Replicator G and remove the lines from the scripts altogether.

    This would be a good thing to put in the QIDI group as well. It's also useful for people who haven't shelled out for Simplify, as G-code is G-code (for the most part).

    I've modified these for Slic3r, if anyone's interested.

    I've noticed that when I am printing with a single extruder, the unused extruder still gets very warm. Perhaps a change to the GCode scripts would be appropriate? The changes I suggest are shown below. Any reasons not to do this?

    For the Left Extruder:
    Change From - G130 X80 Y80 Z40 A80 B80 ; Default stepper Vrefs
    Change To -
    G130 X80 Y80 Z40 A05 B80 ; Default stepper Vrefs with unused Right extruder at idle

    For the Right Extruder:
    Change From - G130 X80 Y80 Z40 A80 B80 ; Default stepper Vrefs
    Change To -
    G130 X80 Y80 Z40 A80 B05 ; Default stepper Vrefs with unused Left extruder at idle

    No changes are needed within the Both Extruders script

    FYI the latest Simplify3d update (June 2016 ver 3.1.0) includes a profile for the Qidi Tech 1 in it's printer model choices. I haven't compared all the settings to the ones listed in this thread, but it seems to work well for me.

    Someone had noted some stringing compared to previous manual settings. Did you have any stringing?
    I'm on the fence about getting S3D. The more I read the more I think it is the way to go.

    I know this is not the exact printer but I am looking for this same information for the QIDI X-ONE to be used in Cura. Any help would be appreciated - trying to get a head start on the setup just ordered this printer today from Amazon.

    Hello all- new here to the forum and just bought a QIDI X-One. I'm looking for some direction here please. So I hate the stock software that the X1 came with and want to use Cura (2.3.1) which I am accustomed to. I'm looking to get the proper info set up in Cura for the best prints. I can't seem to find any post pertaining to this printer. I know Simplify 3D supports this printer but really did not want to spend 150$ on software. Any help would be appreciated....

    Or if anyone have Simplify 3D I would love to see the setting it has for this printer so I can use Cura which I as used to... Thanks you all.
