    Hi Paul, sorry to hear that this happened, we haven't experienced this issue in the past with End-Of-Spool mode. Could you please share your MSF with us? We'll take a look to see if there's anything wrong with the file that is generated in Chroma.

    You certainly can use the Change filament function, but the purpose of End-Of-Spool is to make the process easy and able to be completed without supervision. Once we can review the MSF, we should have a better idea of why this is happening.

    Here is the MSF file.

    Thanks for sharing, Paul. Taking a look at the MSF files, the lengths are correct as it does tell Palette to splice at 4500 mm, 4500 mm, 6500 mm, then 2500 mm, so this looks to be an issue with the PV of your Palette. Here are the steps that we would recommend in order to fix this issue:

    • In Chroma, create a duplicate Printer profile by exporting your current profile, then re-importing it into Chroma (Profiles > Printer Profiles > Export. Save the YML file, then select Import on the Printer Profile screen)
    • Edit the new profile and go to the Palette tab. From here, select Re-calibrate Printer with Palette > I already have values.
    • We're going to take the Print Value and multiply it by the difference in percentage that we're seeing in your values (4500/5487 = ~0.82)
    • For example, if your PV is 179000, your new value would be (179000 * 0.82 = 146780)

    Once this is done, please re-process the MSF file and run the print again.

    Thank you, I have done this process now and when I find some more scraps of filament I will test it out.

    In the meantime, are you able to answer the other question I had in the original post, namely:

    "The instructions do not specify, however I assume when I am running without a printer I leave the scroll wheel off? The instructions should probably be updated to state this (unless I missed that)."

    I just wanted to confirm that since I wasn't sure if the filament statistics are coming from the Palette itself (I assume so) or the scroll wheel.

    Hey Paul, sorry to overlook the question in your original post! No, there is no need to use the scroll wheel when running print modes without a printer. The scroll wheel is only needed to check calibration during prints.
