No success with P2

    Hi Kim, thanks for sharing this information with us, we're sorry to hear that you haven't had much success yet.

    Concerning the earbud case, it's acting as if the input ran out of filament and switched to the next available drive. Did you notice if the input was responding incorrectly? Please go to Settings > About > Next > Next on your Palette's screen and see if the switch's status changes when there is filament inserted and when there is no filament.

    Concerning the pings, it looks like the extrusion of your printer may not be consistent, leading to the varied pings. Have you run an extruder calibration recently? https://mattshub.com/2017/04/19/extruder-calibration/

    Hi Jonny,

    Thanks for your answer.

    The input seems to respond correctly. I just did a test with the four inputs and they all turned to "pressed". The coaster print, after the earbud, also used the four colors, and the white has been used until the end of the print. So P2 was using all four colors for the coaster print. The white spool is still nearly full.

    I haven't run an extruder calibration yet. I'll do that tomorrow by following the link you sent. 

    Should I then do a reset of the P2 and redo the 2-color calibration print, followed by the earbuds?

    Hi Kim, thanks for sharing this information. Yes, I would recommend factory resetting and re-running the calibration steps once this is done.

    Hi Jonny,

    So I did everything you suggested. My extruder is now perfectly calibrated. After a reset of the P2 I printed the 2-color keychain. It came out perfect, as always.

    Here are the pings of the keychain:

    PING (%)
    ===================
    Ping 1 98.82%
    Ping 2 96.64%
    Ping 3 96.70%
    Ping 4 99.08%
    Ping 5 99.17%
    Ping 6 98.73%

    After this print, I moved again to the earbud holder. For this, still no success. P2 is still mixing colours and pings jump up and down. It seems that P2 corrected itself during the print, the top layers are correct. So I saved the calibration since there were no missed pings.

    Here are the pings of the earbud holder:

    PING (%)
    ===================
    Ping 1 99.41%
    Ping 2 99.08%
    Ping 3 99.37%
    Ping 4 100.56%
    Ping 5 101.07%
    Ping 6 100.87%
    Ping 7 100.67%
    Ping 8 100.52%
    Ping 9 100.36%
    Ping 10 100.83%
    Ping 11 101.97%
    Ping 12 102.36%
    Ping 13 102.36%
    Ping 14 102.36%
    Ping 15 93.89%
    Ping 16 93.96%
    Ping 17 94.65%
    Ping 18 94.65%
    Ping 19 97.24%
    Ping 20 96.85%
    Ping 21 97.03%
    Ping 22 97.40%
    Ping 23 97.68%
    Ping 24 97.63%
    Ping 25 97.38%
    Ping 26 96.94%
    Ping 27 97.80%

    Will it be an option to print the earbud holder again, since P2 now has a better calibration or do you suggest doing other things. Maybe something I'm missing?

    Thanks.

    Hey Kim, thanks for following these steps! Although the earbud case isn't perfect, it's great that you saved the pings to that Palette can learn more about your printer. I would suggest running another print (non-earbud) and see how the calibration of this piece turns out.

    OK, great. I'll give this calibration model a try:

    https://www.thingiverse.com/thing:3282265

    I think this one will give some good pings. I will let you know how it turned out.

    So, here we are. It came out not too bad, but still with some minor error which P2 fixed on the go.

    Here are the Pings:

    PING (%)
    ===================
    Ping 1 101.56%
    Ping 2 100.46%
    Ping 3 95.04%
    Ping 4 94.13%
    Ping 5 94.13%
    Ping 6 94.13%
    Ping 7 95.38%
    Ping 8 96.39%
    Ping 9 94.27%
    Ping 10 94.27%
    Ping 11 96.82%
    Ping 12 96.81%
    Ping 13 98.88%
    Ping 14 97.49%
    Ping 15 98.35%
    Ping 16 98.05%
    Ping 17 98.00%
    Ping 18 99.93%
    Ping 19 98.23%
    Ping 20 98.37%
    Ping 21 98.81%
    Ping 22 98.10%
    Ping 23 99.54%
    Ping 24 98.74%
    Ping 25 98.55%
    Ping 26 99.44%
    Ping 27 97.84%
    Ping 28 98.34%
    Ping 29 99.79%
    Ping 30 98.90%

    Here is the outcome model:

    Yellow came out perfectly. Black has one line of grey, green some lines of black and white part has some lines of every color. 

    After all, I saved the calibration, since the last layers seem to be all ok.

    Is there something I can tweak to get rid of the errors or should I just keep printing and let P2 learn more? Until now, only the 2-color Keychain was a success.

    Thanks

    Thanks for sharing, Kim! The overall calibration looks great so it looks like Palette is learning more about your printer with every print. I would suggest that you keep printing to provide your Palette with more pings and information to adjust the HM for your printer. The more information that you can create and record, the better! Thanks for your patience with this, Kim.

    Thanks for your patience with me Jonny :-)

    I know printed a 4-color Mosaic Keychain. It went perfectly until the 2 last layers. But, it seems, there are less errors with every print. 

    Here are the Pings, which I saved afterwards:

    PING (%)
    ===================
    Ping 1 105.55%
    Ping 2 103.67%
    Ping 3 99.50%
    Ping 4 99.25%
    Ping 5 100.06%
    Ping 6 99.08%
    Ping 7 99.99%
    Ping 8 98.70%
    Ping 9 98.86%
    Ping 10 100.92%
    Ping 11 99.26%
    Ping 12 99.25%
    Ping 13 98.61%
    Ping 14 98.22%
    Ping 15 100.98%
    Ping 16 100.98% 

    As you can see, Ping 1 and Ping 2 are far away of what was coming afterwards. Over all, a good print. P2 starts to know my printer I guess.

    Hey Kim, thanks for sharing! I agree, it looks like your prints are improving, so it would be best to keep printing and saving calibration values. Try a larger print and share the results!

    Hi Jonny,

    As you recommended, I printed something bigger with more pings, but not less complex :-) I did the Mosaic soap dish and it came out BRILLIANT :-) This time, the pings were all around 105%. Is that bad or doesn't it matter as long as they are not far away from each other?

    Here are the pings:

    PING (%)
    ===================
    Ping 1 105.95%
    Ping 2 105.13%
    Ping 3 104.02%
    Ping 4 103.83%
    Ping 5 103.83%
    Ping 6 107.41%
    Ping 7 107.54%
    Ping 8 107.41%
    Ping 9 107.26%
    Ping 10 107.12%
    Ping 11 106.28%
    Ping 12 105.43%
    Ping 13 105.48%
    Ping 14 106.24%
    Ping 15 106.11%
    Ping 16 105.56%

    Ping 19 105.62%
    Ping 20 105.31%
    Ping 21 105.15%
    Ping 22 105.50%
    Ping 23 105.56%
    Ping 24 105.58%
    Ping 25 105.28%
    Ping 26 105.39%
    Ping 27 105.85%
    Ping 28 105.43%
    Ping 29 105.38%
    Ping 30 105.51%
    Ping 31 105.47%
    Ping 32 105.23%
    Ping 33 105.48%
    Ping 34 105.46%
    Ping 35 105.46%
    Ping 36 105.68%
    Ping 37 105.20%
    Ping 38 104.98%
    Ping 39 105.12%
    Ping 40 105.02%
    Ping 41 105.08%
    Ping 42 104.97%
    Ping 43 104.98%
    Ping 44 104.89%
    Ping 45 104.77%
    Ping 46 104.77%
    Ping 47 104.62%
    Ping 48 104.54%
    Ping 49 104.56%
    Ping 50 104.32%
    Ping 51 104.17%
    Ping 52 104.32%
    Ping 53 104.46%
    Ping 54 104.78%
    Ping 55 104.54%
    Ping 56 104.27%
    Ping 57 104.09%
    Ping 58 104.22%
    Ping 59 104.15%
    Ping 60 103.73%

    And here is the result. As I said, it came out perfect!

    Thanks for your help.

    Great to hear, Kim! The higher pings aren't an issue as long as they're consistent, so I would't be too concerned. The print turned out great, and we can't wait to see what you print next!
