Outgoing Drive Gear Strips Filament and creates a Blob and stuck to ge

Unable to splice material. For some odd reason, the gear grabs it and puts a head on the splice. Picture shows the filament broken, which I had to break to show the picture, but the two pieces of the same color and they are attached after the gear does something to it. It make a loud grinding noise. Plus the filament gets melted into the gear. What would be causing this? Trying to set up the splicing between two colors.

Thanks.

Hi Jim,

I'm sorry you are having issues getting proper splices. I would be happy to assist.

From the look of this photo, we will need to run splice tuning to find the proper values for your materials. Would you mind telling me the splice settings and the exact filament you were using when the issue occurred? This will help to determine what modifications we should make to your heating, compression and cooling. This splice tuning guide is also a great resource to refer to as we go through this process.

If you could, please send that info to me at shane@mosaicmfg.com, or we can continue the conversation here. Whichever you prefer!

Looking forward to your reply.

Shane, I manually entered the following when it asks for it:

Heat: 3, Cool: 3, Compression:2 during the first splice.

Then when it completed, it said "Save to Material Profile" and these are the settings it suggested:

Heat: 2, Cool: 3, Compression:2

The filament looks great, it fused the two colors together and real tight and does not break.

Then I have a file on the Palette 3 Pro, so I launch that to print. Then after the third splice it ALWAYS fails and the gear eats some of the filament and leaves a blob that cannot pass through the tube, it grinds, and stops.

I am using HTPLA (Hight Temp PLA) by ProtoPasta. It works great with my PRUSA.

Filament Info: Proto-pasta Carbon Fiber Composite HTPLA is a combination of milled carbon fibers and high-performance, heat treatable PLA (HTPLA). Resulting 3D printed prototypes and end-use parts are characterized by exceptionally stability of form and potential use up to 155 deg C (310 deg F) when heat treated

Ok, perfect, thanks for this info Jim! I'm sure we can get this resolved for you.

Could you share your Canvas project with me please? I'd like to make sure the settings you have worked out have properly applied to the print. The share button is in the top right of the screen. Please tick all the boxes (material, printer, style settings) before sharing, as pictured below:

You can send them to me at shane@mosaicmfg.com. Thanks again, Jim! Look forward to hearing from you.
