Cura has a habit of updating; to prevent that go into file>preferences>cura settings and uncheck the check for updates if you desire to use an older version. That's what looks like may have happened from your screen shot.

 

[Gabriel]

It does want to update every time I start it.

OK, I printed the block again with the nozzle and filament diameters corrected. The belt must have skipped or something a little way in. I let it finish anyway to see if it would do it again, plus I didn't really need to start it over just to print the test block...

Not sure what else to mess with to get it to print nicer... plus the one side is still 1.5mm short (actually, I just put the calipers on it and it's 18.9mm, so it's not as small as the last print).

 

[Ericpwp]

I think the smaller one is the newest. 3.2.1 I think.

 

[Gabriel]

The 15.04.3 (the one that is full screen) is the one I used for the last two prints. I couldn't even figure out how to change and parameters on the 3.2.1. I never said I was good with computers, though.

 

[Ericpwp]

Well it only skipped one time from the looks of it. There is still a problem with the top layer. It seems like there is still not enough filament. It could be a calibration on the z height. I don't have an ender. Is your filament feeding smooth, or is the machine yanking on it?

 

[Ericpwp]

You need to set up cura so it knows what printer you are using.

 

[Ericpwp]

on 3.2.1 click setting> printer > add. put your ender in.

 

[Ericpwp]

SO to be clear, I think you have the wrong printer in cura. It has different calibration settings then the ender you have, hence the almost good prints.

 

[Gabriel]

The Ender 2 isn't an option, which may be part of the problem.

 

[Ericpwp]

try the newer cura

try the newer cura

It isn't an option on that one either. The 3 is on there, though.

 

[Ericpwp]

Oh, maybe try that, I don't know the differences. Robby may come along and help. I think he said he had an ender.

 

[Ericpwp]

The web said try the CR-10 profile and change the bed size.

Thank you. I'll give that a shot. Also, I was wrong, the only Creality printer on there is the CR-10. Not sure why I thought I saw the 3 in the list.

What speed are you printing at? And what nozzle temp? How many shells?

I see some ringing in the sides of print. Might be you need more shells though. Try 3 if it is 3 try 4. The top looks like it is printing to hot and maybe not enough shells.

Robby should be able to hook you up with a good profile.

 

[Gabriel]

I assume the shell is how thick the outer walls are (how many passes for the wall). I don't see where to change it at the moment. I will look around a bit.

The speed (or layer height) is at .2 . I was printing at 200 and the bed was at 55. I changed my printer to the CR-10 and changed the bed size for the last print and I didn't see if Cora changed the heat settings for the last print I just did.

Here is the last one on top...

 

[1911ly]

Correct, shells are the layers on the top, bottom and sides. All are adjustable in the slicer.

I use S3D. I haven' t used Cura in a long time. What version are you using? You really want the newest version that is not a Beta build. I can down load Cura and go over the settings with you. Let me know if you have the latest version and I will down load it.

Hopefully Robby will be on line soon. I know he can get you setup.

Don't get frustrated. We'll get you dialed in. NP.

I am using the latest version now. I had an earlier one, but updated it. I'm certainly not opposed to downloading something else. That was just the first program I came across so I could convert files from Thingiverse.

I'm not frustrated at all. I did spend a lot more time today messing with it than I intended. I meant to be out in the shop putting handles on a couple knives, but this is interesting also.

Edited: I found the shell info. the last one printed the walls at .8 and the top/bottom at .6.

 

[RobbyMaQ]

Ive heard some issues with latest cura but cant confirm that. I have a profile that pretty basic for cura but like larry i use s3d mostly. Depends on the model most times.
Pm me an email address and ill email you whatever i have on the ender 2.
Off top of my head nozzle should be .4 the spare is a .3. Filament diam should be 1.75. If it was set to 2.85 before then it would have pushedlesss filament through while thinking it was pushing more. Hence the under extrusion.
Flow or whatever cura calls it should be 98-100%
Most prints can get away with 3 top 3 bottom and 3 or 4 walls. I think cura defaults to actuall dimension vs wall count but i know theres a way to change that.
Id bump your temp to 210c theres a lot of leeway but 200 may be on the low side.
Watch your bowden tube to see if it's slipping in and out during retractions and listen for any skips or clicks in the extruder gear (pushing filament too fast and motor skips because it can't turn anymore)

 

[Gabriel]

I found the shell dimension and you are correct, it lists it as .8mm walls and .6mm top and bottom.

The PLA is Hatchbox 1.75mm.

I will keep an eye on the filament next time I print, but haven't heard any odd clicking (although I didn't hear it when the entire thing skipped on the second print either and I was sitting right next to it).
