Hello all, this is a joint project by: @Mechanikus @MrBean @i3sven and the kind support of the Snapmaker J1 team. Today we present you, our findings and solution against the clogging problem on the J1. In this document you will find everything that leads to the problem and what it takes to so…

I see the same, after I disassembled the left hotend yesterday and added thermal paste, ran a 6h job through. Have already ordered me for safety materials for the conversion and taken these fans from Younuon. [image]

Has anyone ever considered what would happen if the fan is turned around? Then it would suck the air through the heat sink. Currently he pulls the air from the motor housing which is heated by the engine with. I have after a 3h print almost 10 degrees more in the housing than at fan height above th…

AFAIK, usually you say “pushing is more efficient than pulling” when it comes to fans on a cooler since the pushed air is more concentrated directly behind the fan (which also something you can feel). Therefore I would think that the direction Snapmaker chose is the better option in this case.

Potential nozzle option: Slice has a new nozzle geometry, called AP3X, designed for non-planar and 45 degree belt-printers. But the conical tip should work well for the J1. They have an even newer version coming in a material called “GammaMaster” that is both hardened and thermally conductive. …

Now if they would offer that one in 0.2mm as well that would be indeed an interesting option! But even as it is, this might help users that want to do the heat break switch. Thanks for the information!

Hi guys, I would like to share a easy solution for the clogging issues. Its only necessary to buy parts and dis- and reassamble the hotend. There are two variants I built: (recommended): You take the original nozzles buy the suggested heat breaks (<a href="https://www.igo3d.com/bondtech-mk8-heatbreak-copperhead?curr=EUR&utm_term=&utm_campaign=0.3+%5Bcb+-+MaxPerformance+-+shopping+-+DACH%5D+Weitere+Produkte&utm_source=adwords&utm_medium=ppc&hsa_acc=2959589712&hsa_cam=17785743817&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gclid=CjwKCAjwjYKjBhB5EiwAiFdSfmRMiXB7tFdAQnBKeP0gNj2bTLpIaHI_8pW9FXYXoq2vaGutQPW-ZhoCUfYQAvD_BwE" class="inline-onebox" rel="noopener nofollow ugc">Bondtech MK8 Heat Break für Copperhead Hotends…

So you don’t cut the adapter and use them with the copperhead heat break and the original nozzle? Did I understand that right

Hi there - thank you for providing links to order these pieces. Can I trouble you for more photos or a detailed description of your first option? It seems easiest and I just want to get the printer in working order. Struggling with this thing since January with no assist from Support.

I have also confirmed with them that it is electrically conductive, and have placed the order.
