@beejack Hi, thank you for your thoughts, at the same time I have also contacted the creality's customer support via eMail and got responce... Well, they think the mainboard is burned out and I have to replace it...

Hello, just wanted to give a small feedback after I have upgraded my printer. Yeah, Creality support member from customer service wrote to me, but I have the feeling like he has no idia from the product, thats why I havent answered to him anymore and found the solution on my own. His answer to this was: "The printer’s E-axis transmission ratio is fixed at 93 and cannot be increased or decreased" Well.... After that words I can only imagine that he has no idia from the creality 3d printers because everyone knows that the default ratio can be adjusted even officialy via the printer's screen. After some searching time I have found the software pronterface and guide in youtube how to use it. Adjusted the ratio to 403 (perfect steps ratio in my case) and am using since last saturday the BMG extruder, first as bowden setup and now in direct drive (almost, kinda hybrid with a short tube) setup with phaetus dragon hotend. Prints are perfect, no clogging or slipping anymore.

Hello, just wanted to give a small feedback after I have upgraded my printer. Yeah, Creality support member from customer service wrote to me, but I have the feeling like he hasn't read my thread at all. The eMail titel and his answer to this was: "ENDER-3 V2 Nozzle blocked problem Dear customer, Please refer to the tutorial to clean the throat. After cleaning and installing the nozzle, first tighten the nozzle and then relax the nozzle 90 degrees, insert the Teflon tube to the end, and then tighten the nozzle. https://www.youtube.com/watch?v=viiRuI9d9YM&feature=youtu.be The thermistor is damaged and you need to purchase the thermistor to replace it. If there is still a problem after replacing the thermistor through the operation of the previous email, please provide a video for analysis. " Well.... if he would read the thread properly, he would know that the problem is not the nozzle related and that I have written that yes I broke the default thermistor and already ordered a new one. Until I broke the thermistor I was freely printing with PETG with the same nozzle as PETG and it was printing well and I have written about it in this topic so yeah... Even the damaged thermistor was able to print with PETG anyway. I have nevertheless exchanged it without any difference. Thanks to "Sunkione" in the BMG extruder thread (he wrote that he had also problems with Silk PLA on stock hotend and solved it by building in DDE extruder + hotend) I have decided to buy the Phaetus Dragon hotend in addition to the BMG extruder, have reworked the mount https://www.thingiverse.com/thing:4369859 to fit the Dragon hotend with BMG Extruder holder on top and printing with very nice results now, 10 hours prints till now are perfect with PETG, Silk PLA and I have even Ultra Silk PLA hehe, working very well for all of them. I am very satisfied with BMG+Dragon, retracts just 0,8mm for PLA and 1mm for PETG without any stringing at all on the models I am printing for both PETG and PLA. So yeah this was my solution.
