    I can splice demo well, 2 colors 3 colors 4 colors was ok, but when I try to print two colors stl, when palette ask input 1 pla, 2 pla, I do it, after that palette transmit some 1 pla and cut it, when transmit 2 pla the system always show error code 301, or 302, I try to use 3 pla and 4 pla the same issue happen, how can I do now?

    I don't think it a jam or  filament issue because I can succeed finish splice demo

    Hi Jemmy, it sounds like there may be a small blockage in your Opto sensor, which is causing the 302 error. This could be a small piece of filament or dust in the Opto area, and there are two steps I would recommend:

    1) On Palette+'s screen, please go to Utilities > Jog > Drive 1 > With Outgoing > Automatic. When you turn Palette+'s dial, it will control the ingoing drive for Drive 1. Feed a filament through and jog it through your Palette+ to push out any debris.

    2) Follow the steps in this support article to access the Opto area, then use compressed air to clear any dust: http://mm3d.co/302

    I don't think that's a reason, if Opto had dust why splice demo done well (I mean after 301, I use Jog pull out all filament), and start splice again, it success, I had a question, if STL is small, the first color is too short to reach outgoing drive, do you think that cause the issue?

    If the first color is too short for the filament to reach the outgoing drive, Chroma will provide you with an error code and will not process your file, so that's unlikely the case. Although your unit can complete Splice Demo, I would still suggest using compressed air in the Opto area to clear any possible debris that could be causing the 301/302. If you think that your files are causing this issue, please feel free to send them to us at support@mosaicmanufacturing.com and we can review them for you.
