I have posted something about Edner 7 on the Facebook group and received a lot of feedback.

Seems there are many disappointment and dissatisfaction for Creality.

What do you think about Ender 7? 

Is he really a new generation of the fast printer?

My concern about Ender 7 is the nozzle.  It said one of the trick for this machine to achieve high speed printing is by implementing a customized high volume nozzle.  Does that mean normal nozzles not going to work?  Or it will work but at slower speed?

@nice Yes, the larger storage tank is to prevent the problem of insufficient extrusion when the speed is too fast. I am not sure if the screw of the normal nozzle will fit Ender 7. But theoretically, I think it can work at a slower speed.
By the way, The noise of the belt movement is very loud when Ender7 works at full speed.

I just set up my Ender 7 this week, after some annoying issues with assembly. I had two metal screws jam and fail halfway into their sleeves, even though they'd screwed in perfectly normally to that point. I suspect some small problem with the threading in the sleeve was the culprit. I had to saw one of the screws in half to get it out, and then punch the insert out. Then the endurance test began with trying to get warrany from BangGood. Suffice it to say, after 6 weeks I finally (on the advice of the Online Creality store) just fixed it myself. I should NOT have to repair a brand new printer- this is bizarre. 

Anyhow, I got it to print a nice boat benchy. ( couldn't print the God of wealth, because Banggood didn't send me the SD card with the exemplar prints AND the manual for the printer in PDF.

I really need that manual. The Ender 7 prints very nicely in the center section of the bed, but as soon as I try to print a larger model, the filament doesn't stick, and it winds up creating spaghetti, and a clump around the nozzle.  It's the white Creality Filament, and I've tried the following settings:

Hot end 200 Bed 50.

Hot End 220 bed 65

Hot end 240 Bed 70

Hot end 215 bed 60.

I've tried varying the level a bit, but making the paper drag more or less under the nozzle in each corner.  

Printing the benchy at 100 % and 200% worked fine at the bottom two settings.

But any larger model comes unstuck after a few minutes. It either spaghetti's or the raft or brim lets go on one corner and the print fails either way.

Any suggestions? I THINK it's a leveling issue; the left front corner seems out of whack. I've tried using the adjustment nut and lock on the Z axis to give me more 'room' on all corners, but again, without the manual, I'm sort of working in the dark.

This has NOT been a good experience. IF they can't include the SD card with the manual and prints on it,  (and they tell me it's a customs issue) then they should at least make everything on the SD card downloadable from a cloud location.

Any ideas and help gratefully received!

@dave-l hey man you have any luck? ive been looking online and i see like absolutely nothing about the ender 7, as in user wise soo what i have found to work leveling is use the ole paper trick then start the print and adjust as its doing the first few layers but remember if you turn one the opposite s going to counter so easy does it and temp wise i usually do 215-220 then 50-65 pretty much depends on the size of project. ive had a few issues my self but im also completely new to the print game. All i know is i most likely wont be buying creaity again. but with a little hope and dedication i will make this ender 7 the most bad a$$ first printer there is. ohh and goodluck with customer support lol.

After having owned both IMHO the Ender 6 is better in a lot of ways. 

Ender 7 has

better hotend 

better bltouch placement behind the hotend rather than off to the side 

linear rails

USB-C port for USB-C thumb drives

 

Ender 6 has

better mod support

better frame

enclosure

larger print volume, 290,290,400

cheaper to buy

faster than the ender 7, e6 300mm/s, e7 250mm/s. The e6 is easy to get to 250mm/s whereas the e7 was extremely hard to get past 200mm/s with stock heads.

better cantilever bed with 20x20 extrusions as support 

 

The sag on the ender 7 bed is so bad for the increased price along with a worst frame design and smaller print volume. You can purchase the ender 7 hotend kit for the Ender 6. You can place the bltouch on the proper area with a modded firmware and direct drive mod easy enough. Linear rails can be added to the ender 6 with 3 3d printed parts. The e7 bed sags and falls like it did on the e5. I have no idea why they went back to the ender 5 plate rather than the far better extrusion design on the ender 6. There are these brackets you can add to the ender 7 in the box but the added weight causes the bed to fall when no power applied to the stepper motor. The Ender 6 is nice and sturdy, you could drop a car on it, the ender 7 wobbles and creaks and moves causing a LOT of ghosting. The Ender 6 came with a much larger bed than advertised and the Ender 7 bed was somehow the exact size. Overall the Ender 6 is a MUCH better printer.

I've had an ender 5 for a year or so and absolutely love it. I have had the ender 7 for about a month now and it has been a nightmare.  I'm at about a 75% fail rate with the 7 when I have only had a handful of failed prints with my 5 in the entire time I've owned it.  I've even dialed the 7 back to the same speeds I print with my 5 but it just fails.  I've noticed that the center of the bed is slightly lower than the corners so the corners have to scratch to get the nozzle close enough to adhere in the middle. Nothing sticks and most of the time a piece of the print will come up and cause a failure.  The failures also don't spaghetti on the 7 for me, they just pull up into the hot end and then I spend a couple hours pulling a huge blob of filament from my hot end.  My latest attempt to help was ordering a custom PEI bed in hopes of improved adherence to the bed. Didn't help, still failing most prints. Even the few that competed are warped on the bottom where parts have come up.  

Also, the printer is way louder than the 5.  I'd stay away from this one, wouldn't recommend to anyone

@kevin well, I'm not really very happy with the Ender 7 so far. I would not recommend it to a beginner. It's very difficult to level the bed, I can't get the BL touch to work, and the first one failed on me in assembly.  some of the machine screws were jamming in their holes badly. I had to cut one out and then take the machine apart and replace its placement tube with a screw, nut, and lock washer. I had to pull the power supply to do that.

Banggood was not able to supply a new bottom assembly, but they allowed me to repair it without voiding their warranty and offered to pay for the parts. I fixed it, got it working, and then it failed catastrophically on a print after I foolishly left it unobserved. It jammed so much melted filament around the hot end that it destroyed some of the wiring and repair will require the replacement of the head and a lot of labour. At that point Banggood simply sent me a new one. I've become a fan of Banggood- they really did do their best for me. But the Ender 7? it has great potential but of lot of design issues. I had to take the base off just to flash the screen files for the BL touch, and then I had to take the top off and one of the axis bands in order to attach the BL mount to the hot end unit.  Now I can't get the darn thing to work properly. Arggh. I CANNOT recommend this printer to anyone who is not quite experienced.  My first printer was my Ender 3, and assembling and modifying that gave me enough experience and confidence to deal with all the issues on this Ender 7.  But, given the option, I'd just send the darn thing back and get something else. Having fought with two of them now, I'd never buy another. And finding help for it on the Creality site? Good luck. Yet... it has real potential, but it needs some refining. So.. Banggood... GOOD! Ender 7? not so much.

I still need to figure out how that stupid Z level screw works. And I surely wish the firmware's user interface was half as good as that of the basic Ender 3. The Ender 7 can only see files in the root directory, and the motion controls are extremely limited and barely functional. If the firmware was a candy, it would be peanut BRUTAL.
