    • RE: Ender 3 V2 Black Screen after BLTouch Update

      @beejack Hello, thank you very much for the fast respronce, very appritiate it.
      The youtube video was nice addition but unfortunately didn't solved my problem. Firstly I have installed the BLTouch directly to the mainboard BLTouch slot (with changing the pins slots to the right positions), now I have tried to put it in as in the video you sent, unfortunately with the same result (changed the pins back to match the video).

      Regarding the firmware for the mainboard and screen - they are from the stock creality website downloaded (the one which are installed now). But yes I have also tried to install some 3rd party firmware's aswell with the same result.

      Also in this video you can watch his full behavior: https://youtu.be/keab1efEuTs

      The BLTouch I purchased is the Creality's Version 3.1 BLTouch from: https://www.amazon.de/gp/product/B082VSB9VP/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

      I hope this will be helpful to help me come further

      Also please don't pay attention (and sorry for that :D) to the mess in the room 🙂

    • Ender 3 V2 Black Screen after BLTouch Update

      Hello everyone, I have another problem here with my Ender V2, weird one.... BLTouch V3.1 from Creality
      I have updated the firmware to the BLTouch firmware, installed the BLTouch, everything successfully (almost).
      At first after the Firmware Update the display didn't turned on anymore, at all, even doesn't light up. The printer itself is turning on, fan's are spinning but the display doesn't react at all. I have tried different Firmware versions for both printer and screen without any succes....
      BUT...
      Then i plugged in the USB cable from the PC and it has started to turn on, indeed no LED's are lightning when I turn the printer on without USB cable, as soon I'm plugging in the USB cable as with magic the LED's are turning on and the Display aswell, it is printing well and do the job right...

      So what is the problem this time...?

    • RE: Ender 3 V2 - Can't print anymore any item

      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.

    • RE: Ender 3 V2 MBG Extruder?

      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.

    • RE: Ender 3 V2 - Can't print anymore any item

      *Update Today:
      Nope, still have the problem, small parts once per printing session are printing without any problem, starting with 2 different small things I get clogging every ~30 min. Bigger parts can print well but can also get clogging same way as on screenshots earlier. Idk what to do.... Used also default Cura Settings for the PLA 0.3mm Nozzle for the Ender 3 Pro, same issue there. Printing quality is very good until its starting the clogging. Used defaule 93 E-Steps, also calculated the steps according the internet up to 96,9 steps so it is pushing exact the same lengh of filament as it used to, tired different flows, different retracts, with combing and without combing. Nothing gave solution this far.

    • RE: Ender 3 V2 - Can't print anymore any item

      @DNW Ok well seems like I have solved my issue, not that easy but my first 7 hours print with the same PLA came out almost perfectly, extruder motor skipped from time to time like 3-4 times in a row but that has not disturbed the print as far I can see and I guess the slims are linked to the forgotten adjustment of the 98% filament flow rate as I am printing again with the 0,3mm nozzle, need to reduce this one aswell for the future prints.

      Well, I have made a few changes.
      First of all I have printed the mount for the direct drive mode (self developed) with PETG for the default stepper motor size. At the same time because I can't use the BMG extruder due to not be able to adjust E-Steps higher than 186, I have modeled the mount for the stock (all metall) creality extruder and mounted it together, everything is fit just perfectly with the frame.

      Second step was to exchange the heatbreak with an fullmetal titanium heatbreak + reduce the retraction ofcourse because of the direct drive mode down to 0,8mm, retraction speed is by 25mm/s.

      And the third one, I have installed the stock Marlin Firmware for the E3V2, which was put toghether from an other person based on the latest Marlin release. The person is doing the Firmware updates daily, well a big thumbs up for that.

      At the end the printing quality made a big step up and the prints are even much better now than before (test cube based opinion) the edges are just incredible better now.

      With all of that said I can mark the thread as resolved.

    • RE: Ender 3 V2 MBG Extruder?

      @admin hello, thank you for the responce.

      I am trying to solve this issue https://forum.creality.com/topic/124/ender-3-v2-can-t-print-anymore-any-item. PLA is clogging in the Heatbreak after hours of printing and I am trying to solve this somehow on my own because noone can give me any solution for my problem.
      So that is try and error and I have read on the internet that the BMG extruder has perhaps the power to push the filament threw so the clogging in the heatbreak can't be build up that far to block the filament coming out.

      Well, I saw on the internet that many people are installing the BMG Extruder on Ender 3/Pro without any problems and thought OK if that is possible on the older Ender series - it would be definitely possible on the Ender 3 V2.

      Till now I have used the stock V2 extruder, the metall creality extruder, different springs on for the tension on the extruder => without any success. They are starting to slip after hours of printing because of the clog in the heatbreak => So the logical thought - the normal creality extruder arent as strong to push the filament threw the warmed up PLA in the Heatbreak => have to try something stronger => BMG extruder has ~x4 the strengh for the pushement => have to try it out.

      I have also already tried titan fullmetal hotbreak but got a few problems with that (my own fault) but havent tried it yet with PLA, only with PETG and accidentally broke the thermometer when was cleaning the hotend from the plastic and after that the Ender doesnt start anymore at all... Screen is not launching till the end... So waiting at the moment for an exchange ¯_(ツ)_/¯

      If you mean that I am not able and will not be able to install the BMG Extruder then I have only the one options left:
      To purchase an other hotend or another printer... Because all of the other idias I have already tried out without success.

      If you can give me any other solution which I haven found till now based on this 2 topics => I would apriciate that.

      @DNW Thank you for the reply,
      https://imgur.com/a/Wi92Oqz (its an image hosting) here is how it is looking. The once with stretched out ends are which I took out without waiting, the one in the middle is how it is looking after the filament stopps to come out of the nozzle.

      I have exchanged yesterday (wednesday) the heatbreak for an titan heatbreak and printing firstly with PETG an self developed mount for the BMG extruder in direct drive mode but thesefore I have another problem.... BMG extruder needs ~365 transmission ratio/E-Steps but Ender 3V2 has an cap of 186 which I can set up threw the Screen (I have also created an thread for that but it is still not posted on the forum).

      Regarding the flakes, indeed I had this issue firstly but it was linked to the filament entrance of the metall creality extruder (bought separately) and I have quickly printed an holder that solved this and I had anymore any filament flakes inside the extruder. Besides they are so small that I can't see any of them...

      Still try and error... After I get the right mount for the BMG printed I will try the PLA again with the titan fullmetal heatbreak and will let you know if that helped somehow with PLA.
