Filament don't fit into splicer

Palette 3 Pro.

I’m in the group with only one successful print, the key chain.

I’m trying to print a couple of colored benchys.

After some hours into the print it stops. This fail occurs (as I can see it):

Filament will not fit into the splicer. It seems like the cause is the filament have been pressed quite flat by the CAM, and it will not fit into the splicer. When removing the filament (from splicer) I notice quite some resistance.

The last tried filament was PrimaSelect PLA Ambient Gold Glossy. It did also happen with PrimaSelect PLA White regular.

Is there some adjustments that can be made to avoid this?

Do u use 1.75 or 2.85 mm filament (its made for 1.75)

beside that i do have some special filaments myself like a glow in the dark one which is a bit 1.75-1.78 in size keep in mind

when it splices it might be a bit wider its a good recommendation to do some splice tuning for the fillament u wanna use to see if u can improve compression and heat.
Personally i use 1.0.1 for all my fillaments and its working fine :)

I only have 1.75 mm filaments.

When the problem occurs the filament don’t even reach the splicer. It doesn’t fit into it. I can also see that the filament kind of dissolves when CAM pushes and pulls it.

I’ll try other filaments from other vendors to see if that’s the issue.

That sounds like filament that needs drying

A good peice of advice put the filament roll in a seal bag with some sillica and give it 48h at least to get a bit moister out

If moister comes into the filament it enlarges slight beside that it becomes brittle so ‘disolves’ when stressed too much

Did other filaments work OK? if so, the filament might be oversized. Do you have a digital caliper? measure the thickness of the filament. Make sure it isn't larger than 1.75 mm. The tolerance inside the splicer is very tight (so the splices remain the correct diameter). No room for oversize. Also as far as the disolve issue, if the path for the filament is too tight, the cam will eat the filament no matter how much moisture is in the filament. Also, the insert inside the splicer could be distorted and preventing the filament from passing through. There should be spare inserts in the box that the palette was shipped in. Note: once you remove the insert from the splicer it is very difficult to reinsert a used insert so only remove it if you're sure it's the problem. New inserts fit in the splicer easily. If other filaments give the same issue, the insert could be the problem.

One more note: When the filament gets stuck, is it at the point in time where a new splice is being made? of does the issue occur after the color has run through the path a bit? if it happens at the time of the splice, be sure the tip of the filament is a clean cut. A burr or malformed tip of the filament can also prevent the filament from passing through the splicer.

Thank you for your insights! The Palette is now not in use. For the last 10 prints the Palette just stops, for no apparent reason. Mosaic have acknowledged this issue and are working on the firmware to fix this. Have been waiting for this for 3 weeks.
