Hii there,

I’m trying to print out a ton of coins for a tournament that I’m organizing.

However, the coins always have burrs.

How can I remove the burrs without any handwork? (because we print so much of them that it’s quite a problem to do it all by hand).

It’s just an aesthetic thing but we want the coins to look as polished as possible!

Cheers

Hi @KaasInEenHoedje can you upload a photo of a piece with the problem, it’ll help a lot to diagnose. If by burrs you mean blobs on the side of the coins, that may be over-extrusion (or a lack of retraction), but it’ll help a lot to see a photo.

Oh Yes, I forgot to upload those :slight_smile:

You can see the burrs at the sides of the coins.

Hmm, it’s kinda difficult to see exactly what’s going on there, does it look like this:

If so, there’s advice in that page to help overcome it.

Its most likely the seam from layer changes and will always be there to some extent

That looks to me like it’s where the head leaves one coin to go to the next. A little stringing. Increased retraction and/or decreased temperature will help with that.

It does look like this when they come off the printer:

I’ll try to play around with those tips to see if they have any effect :slight_smile:

thanks

Yes it is!

I’ll try to play around with the retraction and temperature a little to see if it has any effect, thanks :slight_smile:

It’s closer to stringing.

Some other folks here gave me some advice on how to decrease the effect :slight_smile: (increased retraction and lower temperature for example)

Thanks anyways :slight_smile:
