I have very strong hate issues with my brandnew (only about 2 weeks old!) Ender 5 Pro printer and the After sales service provided by Creality. And about the poor filament gap design of the standard heatsink with hotend and the just copper nozzle! It worked very well with PLA but my machine now no longer works after I printed in PETG 3 bed supports (1 extra because the second one was not right) after about 20 hours or more!
The 2 printed bed supports in PETG are fine but my extruder suddenly no longer was able to push in the filament. So I cleaned the nozzle and did what many users have to do to fix the damn filament clogging problem. And I afterwards had to push manually in VERY hard the new filament until it came out the nozzzle. Sadly I had to cut the PTFE tube already several times before so no longer could use it to print larger objects. But afterwards my printer no longer prints anything good, not even in PLA. So to tell a long story short. I think the standard machine is only fit to print in PLA very long hours but is destroyed now by just using PETG filament. The Creality after sales help sucks and the promise of sending free replacement parts within the first year of warranty is a claim that is not true! If I get my machine fixed again it is because I get rid of the standard gap issue problem heatsink and hotend with the non hardened nozzle. Why I already bought for about 200 euro/dollar an all metal heatsink with decent titanium hotend + hardened nozzle and new PTFE tube and other replacement parts. So that it really works with all special filaments like PETG, carbon and flexible filaments like nylon which it normally does not! And I therefore will never give any good review about these Creality printers or the shop that sold me this bad supported Chinese machine with its useless warranty!! Even the after sales helpline with the email option can't be used by non Chinese buyers because it requires a Chinese phonenumber to submit any message to Creality. And the answers thay provide didn't help at all! My printer is still completely useless just by printing with PETG and now needs at least new pneufits and new PTFE tube just to get it working again until it will fail again on PETG or the clogging! And I had good experiences before after building and calibrating an A8 ANET printer before! So never expected this poor quality of this bad and bad supported Ender 5 Pro printer!
