    • Did you look at your part in PREVIEW mode in the slicer?  That will let you know if there is anything to print.  There could be a problem with your model (for example walls too thin) where there is actually nothing that can be printed with the current Cura settings.
    • I'm pretty sure it *does* retract when it does "lift head".  But retraction only lasts for a second or so - enough time to jump to a new part of the print.  But lift head will often sit in the air for 3 seconds - plenty of time for a micro sausage to come out and then get deposited on the print when it starts printing again.   The only good solution I've seen is to print a tower next to the part so that the print head can go to the tower and print a little bit to give the print time to cool (just a few seconds is usually enough.  Keep the tower in a position such that when the head goes to it the fans blow on your part (if possible).   Instead of a tower, sometimes I print 2 or 3 or even 7 of the same part.  While printing one parts the other parts all have time to cool.
    • The problem keeps coming up but your exact problem is different.  You can search around here for other threads.  It's fine to discuss it here but there isn't much help because it isn't a Cura issue.  I have an Ender 3 Pro and so does Mari here.  We tend to pay attention to the threads that discuss printers like ours. I tried to chase this down for a couple of weeks late last year.  I ended up at the Marlin Github site and they basically threw me out because Creality took the firmware and made it proprietary.  The Marlin people are not happy with Creality.  There was one poster here (4.4.2 board by btw) who said that a firmware change fixed the problem, but he never explained what firmware.  I tried to message him/her but didn't get a response. At any rate, the 4.4.x board coupled with the Thin Film Transistor LCD display has issues.  The problem lies between the mainboard and the firmware running the display.  I think your best bet is to go to the Creality site and try to get them to explain.  There are a lot of posts on Reddit about this issue as well.  I have not come across a solution there either.  The Ender 3's and 3Pro's being produced now don't seem to have the problem with M0/M1.  It was a 3 to 5 month run of production when Creality ran out of mainboards and (I believe) was throwing in whatever they had laying around.  Maybe they tried a firmware patch and it wasn't enough (because within Marlin there are specific callouts for TFT displays).  They don't say much so it's really hard to tell.  Your display is dated July of last year.  That's right in the period I'm talking about.
    • Which printer do you have and which version did you update to (and from)?
    • Here are all of the specs available. It is an Ender 3 Pro, purchased at the beginning of this month (2021-02) with absolutely zero electronic or mechanical modifications. It has an LCD and the only identifier on the attached circuit board there is ENH12864Z-1 VER1.0. It also has a quality control sticker on it with the date of 2020-07-06. For firmware it is running Marlin v1.0.1 which has a date of 2020-04-25. The mainboard is a Creality V4.2.2.   Since this thread seems to have been marked as solved... Is there a possibility of getting it opened again or should I create a new one? And invite at least Vanadium and Mcmuffin60 to join in?
