Colours not printing

    Hi Graham, thanks for sharing this! I did want to let you know that for the first calibration print, the colors may not be in the appropriate places as Palette is still learning about your printer. As you get more successful prints with your Palette 2 and printer, Palette will adjust its calibration numbers for your specific printer. You can learn more about this here: https://www.mosaicmfg.com/blogs/news/palette-2-uses-machine-learning-to-get-better-with-every-print

    Also, which slicer are you using? If you're using CANVAS, did you load a previous slicer profile or set up a new one? I'm wondering if the settings are causing the extrusion issues you're seeing in your print. I would also check the bed level and retraction settings to see if this helps with the overall print quality.

    Hi thanks for the response. I loaded settings from Slicer. I've tried a second print after adjusting some of the profile settings (and checked extrusion rate, which was spot on) Second print came out better in terms of the print quality, however the colours were still wrong (with one missing completely), I'll try several more prints

    Great, thanks Graham! After a few prints, Palette will hone the calibration of your printer.

    did this ever get resolved? it sounds similar to my issue where the pallet is ignoring inputs at random. do the filament detection lights turn off on the colors that aren't working? even though obviously there is filament loaded.

    Hi Nathan, we're seen cases where the LED lights will turn off, but will continue to load the filament from the inputs. Could you please clarify if this causes prints to fail, or if the filament is still being used but the LED just remains turned off. 

    If the switches aren't reacting, please check the connections of the switches to your electronics board. Please follow the steps here to locate the switches: http://mm3d.co/p2replace-switch

    when the lights are off my pallet grabs from the next available drive with the lights on. I'm actually in the process of a test print with the connections checked going well so far. a new problem has arise'd but it seems firmware/ calibration related instead. i am missing my pings while connected to the hub. and my colors have inverted so.

     

    update never mind even with the connections checked the lights went out again. i had even gone as far as to swap 2 switches with each other to see if one was faulty but the same drive went out again.

    Thanks for this information. When you go to Settings > About, what is the status of your switches:

    shows as not pressed. I've had this happen to drive 1 and 2 frequently. And although I've never seen it i had a print with symptoms of drive 3 as well.

    i should point out as well that it is sporadic. it will be on just fine for an hour some times then be out for an hour. or only a few minuets at a time sometimes. with no real rhyme or reason for the status change.

    Hey Nathan, could you please re-flash the firmware and see if this helps? Also, concerning the switch connections, please try to unplug then replug the connection to both the switches and board. We've seen a similar situation where this helped re-establish a proper connection.

    Here’s what I did today.

    I did a factory reset, cleared my printer data, and re flashed the firmware.

    It should be the most up to date version available. (1.2.1)

    I opened the back of the pallet2 and disconnected all 4 switches and the main plug. Then I reconnected them all to be sure nothing was loose.

    I ran the mosaic keychain print and 46 min into the print the light for drive 1 went out.

    This is after doing everything mentioned above.

    I did a test of the switches. With filament loaded they read as pressed. But as soon as the light goes out even with filament in the drive they read as not pressed.

    Thanks for this information, Nathan. Let me speak with the hardware team and see if we can find the issue.

    Nathan, are you able to manually trigger the switches? When you're on the About screen, can yo please move filament through the inputs to see if they react?

    Hi Nathan,

    at my P2 I also noticed that Drive 1 and 2 sometimes have switched off the blue LED.

    However, I managed to still get filament fed through the drives.

    I have the "Run out Detection" switched to "Off". So maybe this might also work in your case.

    (I described my issue in this crosspost: https://support.mosaicmfg.com/hc/en-us/community/posts/360021784893/comments/360002870353 )

    hi Jonny. 

    i just got home and tried what you said.

    when i tuned my pallet on i went strait to the about screen i still had the filament loaded from yesterday and drive one was saying not pressed, just like it did when i turned it off yesterday.

    i unloaded the filament manually so as to not make the main board change any states by accident. (trying to have as little room for error in the test as possible)

    then proceeded to put the filament back in and the switch changed to pressed.

    i also checked the other 3 they change from pressed to not pressed and back.

    so it seems like at some point the main board looses track of the switches position and changes it to not pressed. that or the switches are bad but i find that hard to believe since i did the swap of switch 2 and 3 before.

    Hi Bastian

    i will look into trying with run out detection off I'm sure the motors will work then and that's a good temporary solution. 

    but i want to be able to use end of spool mode and do lots of long multi color prints so i will be relying on run out detection being on and working.

    update: i tried with run out detection turned off. and yes even though drive one was out it still used the filament. but like i said this is only a band aid as it limits the uses of the machine for me.

    what i really want is on a run out detection a unload input and wait for user setting. so that i can swap out the roll with a new one. also i want my switches to actually work lol.

    Thanks for forwarding this information. I'll chat with the team about this issue and get back to you shortly.

    Also, could you please send us pictures of the connection to your switches and also a picture of the other side of the cables on the main board?

    hi jonny 

    sorry for the delay my power was out all day yesterday.

    ill also note that Adalyn from support is also sending me a couple switches to see if that changes anything. i am skeptical that it will since swapping switches didn't change anything for me in my trouble shooting. but fingers crossed.

    here are those images

    Thanks, Nathan.I'll chat with the Hardware team about these pictures and please let us know if the switches help.
