    Hi Michael, have you run Splice Tuning with your filament (http://mm3d.co/p2splice-tuning)? If so, could you please provide me with your splice settings and pictures of recent splices?

    I tried is at Heating 2, Compression 1, Air 2 - I have the front open.  The last slice was barely holding on.

    I now have it set at 2,-1,2.  Sometimes I get a good bond and sometimes virtually no bond at all.

    Could you please share a video of your unit splicing? I'm wondering if this is related to your Splice Core.

    This splice came out well. It’s hard for me to catch a bad one since it’s random.

    Thanks for sharing. Everything looks to be working properly in the video. Which brand of filament are you using? Could you please also share a picture of a recent splice? It may be that your splice is slightly too thick, which causes the issue as the print progresses.

    This one isn't going to make it. HATCBOX and this filament https://www.amazon.com/gp/product/B07QR5Q8RT/ref=ppx_yo_dt_b_asin_image_o04_s00?ie=UTF8&psc=1

    I replaced the no name with a different filament and it happened again right away.  Wonder if it has something to do with feed 3. When i configure the slicer it only tests with 1 and 2.

    Thanks for this information. Since you're using different brands of filament including a woodfill PLA, it may be best to run Splice Tuning using all combinations with the 3 filaments and creating separate material profiles. We find that splicing with the same brand of filament creates the best bonds, so running Splice Tuning on all combinations should help to produce the strongest splices.

    Please ensure that your splices are consistent and as close to 1.75 mm as possible. If you have calipers, measuring before, on, and after the splice would be ideal. 

    If your splices are thick, I would recommend increasing Heat and Cooling and lowering Compression slightly. The opposite would be true for thin splices.

    I just ran the filament length calibration and the third slot filament did not attach again.  It has to be something to do with the third slot - I have tried a few different combinations and that is where it always messes up.

    Thanks for this information. Could you please try and run a Palette Calibration? http://mm3d.co/calibrate-p2

    This will remeasure your drives and help re-calibrate the ingoing and outgoing drives.

    https://youtu.be/skNwAThPqiQ - That is setup as 3,2,3 in Chroma and same setting for PLA on the Palette 2S - I have tried other settings and same result. If I put the same two filaments into drive 1 & 2 the fuse is strong and you can see the overlap of colors.  When in drive 3 and kind of drive 4 they fuse just touching each other and often don't make it out of the Palette connected.  

    I have run the calibrate numerous times and just did again.  It has not helped.

    Should I exchange the Palette 2S at this point?  I spent the greater part of yesterday trying to get it to work and it's just not consistent no matter which filaments I use.

    Thanks for sharing. What are your SPC and PPM values after calibrating? Also, would you be able to share a video of the calibration process being completed?

    I will do first thing tomorrow morning. I won’t be home for long then so if there is anything else you want to see let me know now and I can do it all at once. Thanks for your help.

    Calibration - https://youtu.be/9Ge7VIQUPTg

    I then sent the same print to the printer.  First time I sent it to print from Drive 1 & 3 where you will see the fuse breaks then the same print for Drive 1 & 2 and the fuse is strong.  I used the same filaments for both tests, you will see me switch the filament to the second drive after the first test. - https://youtu.be/3m55qZe56yY

    Thanks for sharing this information. Since you're using the most recent firmware version, could you please try and turn off Endurance mode (Settings > Preferences) and see if this improves the splices between drives 1 and 3?

    Just tried, no difference.  Filaments didn't make it out of palette attached.

    Thanks for checking. I'd ask if you could please try one more setting of (3,2,3) with Endurance mode off. If this still does not work, we can return your unit back to our offices and we'll take a look to see what is causing this issue.

    I just tried that and it did not make a difference.  Honestly I would like to have a complete replacement and if that is not possible then I will just take my money back.  I just purchased it and it never got thru a full print.  I do not want a unit that needs to be worked on for that amount of money.  Please advise.  Thank you.

    we understand your frustration, Michael. Please send me an e-mail (jonny@mosaicmfg.com) and we can definitely initiate an exchange of units.
