J1 support fast printing. However, some materials are not compatible with fast printing. For example, Silk PLA and most Silk filaments generally require a lower print speed and an increased nozzle temperature. Using inappropriate print settings for some special materials can cause a clog.

Just a side note from the german Drucktipps3d forum: one user there experienced sudden extruder problems at unlogical places, seemingly extruder clicks and jumps.
After a bit of searchng, he found that this issue is firmware related this time, reached out for their support and got the information that the current firnware has an issue with the G92 E0 command.
Thus, if you suddenly have issues now, try to downgrade your firmware first.
Just created an account to say thank you all for the great advise on how to let the J1 become a good printer. Without you, Iād have given up on it.
Especially the thermal paste hint helped to get rid of the clicking I experienced all the time with a bit more tricky filament.
Thank you, guys
From the logic side I guess through the 0.6mm nozzle should be printed easier with less risk of clogging because of less pressure in the nozzle and less needed force of the extruder.
I have had a few issues with heat creep. Iāve solved it by changing the PTFE in the titanium heat break. Removing the stuck plastic is a challenge but I have access to tools to make it easier. Iāve converted my printer to use the new E3D revo nozzles and I havenāt had any issues yet.
Yeah i replaced the stock PTFE with a Capricorn PTFE tube as well.
Only 1.9mm ID and i set retraction in extruder section to 40mm. No clogging with PLA anymore.
Has anyone seen success with the updated nozzles? Iām just about done with the J1 from trial and error and failed prints. Looking for some feedback as I donāt really want to spend the money on the updated parts if they arenāt a solid solution. Thanks in advance
No clogging with the new nozzles. Did a couple test prints. Over 1k swaps without issue. Before it clogged regularly with white PLA. Reduced retraction for filament back to 1mm too.
Thank you for the response. I will look into spending the money on the new nozzles. I sent a message regarding the voucher that was mentioned but not response since last week.
