RE: Need help dialing in Prusa for Ender V2 Neo

Did you attach a zip file? 

I don't see one. No need to wait for permission...

Yes I did twice... I'll try again... I do see it next to [Choose File] as I did each time.

Hi Ron, 
I now have the file thank you. 

What issue do you have with this particular file?

I note that your first layer extrusion width is set at 0.4mm where it would normally be larger, say o.42mm to encourage it to overlap the perimeters

if you could show A picture of the first layer, and any issues, it may help us to help you. 

regards Joan

RE:

The settings for the file included in the zip file are the same settings as in the image above. As you can see it's not that good. 

I'm not sure how to take a picture of the first layer? I could use some direction on that.

I updated the first layer extrusion width to o.42mm. My printer is on the middle of a print (sliced from Cura) so I can't test that out yet.

Does every single post made on this forum need to wait for a moderator to accept it before it's allowed to be viewed by all?

RE: Need help dialing in Prusa for Ender V2 Neo

I just doubled checked my first layer extrusion width and it's at 0.05mm not 0.04mm

RE: Need help dialing in Prusa for Ender V2 Neo

Hi Ron, 
you should not need any more posts moderating. 

the easiest way to take a picture of the first layer of a small object, is to stop the print at the end of the first layer.

If the first layer is big enough to protrude beyond the extruder, just take a picture as the printer starts the second layer

is this the underside of the circular model in the project file?

if so, it looks like the first layer began to form ripples, which usually means that the extruder is a little too close to the build plate, 
do you raise and lower your nozzle using babysteps? or do you adjust the build plate height with screws and springs? 
either way, I think you need to arrange for the build plate and nozzle to be a tiny bit further apart.

the stringing may be due to the filament being a bit on the hot side. or it may be a retraction issue. 

something odd seems to be happening with your .3mf file... 

I first opened it on my old laptop, which opened the file, on my Zaribo printer profile. 
then I have just opened the file on my new laptop,  which I have literally loaded with prusa slicer, and the circle loaded on a Voron profile... 

so I changed the printer type to Prusa Mk3, and now when I load the test circle it loads on my prusa profile... 

did you save the .3mf file from your 3D modelling software, or did you save it from Prusa slicer? 

I ask, because it doesn't seem to be bringing the printer configuration with it.

Does this .3mf file work on your computer? 
Is your computer the ender3 v2Neo?

ok, that suggests the .3mf file didn't bring prusa slicer settings over with it

Yes, this file works on my computer, it was generated by Fusion 360

My printer is the Ender v2 Neo

Yes that is the bottom of my print, On the ender there is a dial to raise the offset. I will raise it  by 0.05mm

I did a bridge temp test in Cura with this same roll and the temps looked ok from 190 to 210. As you see in the gcode I'm at 200°C

Here are the first few lines from that gcode file

• ; external perimeters extrusion width = 0.48mm
• ; perimeters extrusion width = 0.48mm
• ; infill extrusion width = 0.48mm
• ; solid infill extrusion width = 0.48mm
• ; top infill extrusion width = 0.48mm
• ; first layer extrusion width = 0.50mm

I'm not sure where you found 0.40mm?

Edit In:

Still need moderation

RE: Need help dialing in Prusa for Ender V2 Neo

Ron, there is a big difference in a 3mf file saved from Fusion and a 3mf file saved from Prusa Slicer.  A 3mf file is just a handy container format.  It can be used to store a variety of things.  When you save from Fusion and open that in PS then it loads in the model/object data.  As that is all that the slicer understands.  

When a 3mf is saved from PS using the File>Save Project As, then Prusa Slicer ALSO stores copies of the profiles you currently have selected, any modifiers placed, part orientation etc etc.  Basically everything, its a snapshot of your slice.  With a PS 3mf anyone can load it and slice exactly the same as you are doing.

As you want to dial in the profiles being used by PS then you really need to include the 3mf saved from PS and NOT the one from Fusion.

 Thanks for that, I had no idea.

Here is a 3mf file generated from PS. You'll have to remove the .txt from the file

I raised the nozzle 0.05mm and the bottom looks great. Thanks

RE: Need help dialing in Prusa for Ender V2 Neo

Ron can I ask why you aren't using the default ender 3 v2 neo profile as a basis already ?  Someone has gone to the effort to create one and submit it to Prusa for inclusion so you might as well give it a go.

Your custom start and end gcode is a bit simplistic and missing any of the preheat commands or end bed movement stuff that is normal.  Theres also a bunch of other stuff in there thats left over from the old old old defaults for a custom printer.

Why don't you try the attached 3mf file which is based on the PS included profile for the v2 Neo printer.  Its zipped so you will need to unzip it.   The profiles in the project are only loaded temporarily unless you manually save them using the save (disk) icon next to each one.   

RE:

Thank for responding Neophyl

I tried the default ender 3 v2 neo profile, which is still in alpha, and the print came out terrible. The model was something that I sliced in Cura and printed before so I had something to compare.

What you see in my 3mf file is my poor attempt to tweak that profile. I took the settings I had in Cura and used them to update the PS profile. The image you see in my first post came out better but nowhere near acceptable.

What should be looking at in your 3mf neo file? A quick glance it looks the same as mine?

RE: Need help dialing in Prusa for Ender V2 Neo

Use the compare tool in PS.  That way you can see all the differences.   

Are the pictures you initially posted from your first attempt with the default v2 neo profiles ?  Cause those look like theres problems with stringing and also an incorrectly set first layer height (which isnt really a slicer issue) and which Joan has been helping with.

I'd be methodical, get a good first layer, then the usual process to make sure extrusion  is correct (single or double wall cube with no top or infill and checked with a caliper).  Once the basics are down then go from there.  

I do question the defaults settings for bed size.  Whoever submitted it has a different bed size to yours and has a x/y offset in there.  Personally I dont think they should be set like that but I dont have one of those printers to confirm.  Normally an xy offset in the settings like that is to compensate for badly positioned endstop(s).  Thats the sort of thing I would adjust on the physical printer rather than in the settings.

RE:

I loaded both 3mf files in PS and selected compare. PS says they are the same? Am I missing something.

They are after I've been tweaking them

Yes there is problems with stringing and gaps along the top layer and side walls. I'm not sure I understand why that isn't a slicer issue. I didn't have that problem in Cura with this same model only in PS?

I do question the defaults settings for bed size

The bed size for the Ender V2 Neo is 220 x 220 x 250

Whoever submitted it has a different bed size to yours and has a x/y offset in there.  Personally I dont think they should be set like that but I dont have one of those printers to confirm.  Normally an xy offset in the settings like that is to compensate for badly positioned endstop(s).  Thats the sort of thing I would adjust on the physical printer rather than in the settings.

Ok, I'm lost 🙁  As I said, the default profile is not good

RE: Need help dialing in Prusa for Ender V2 Neo

I think we are at a bit of cross communication here.  The project I posted was with the default v2 neo Printer Profile yes.  I meant you could compare it with your version to see what the differences were.  To which there are many.  The defaults start and end gcode look ok and do the preheat temps ect and bed movement at the end yours is missing.  While the extruder settings are important, especially things like retraction distances etc for stringing theres not that much wrong with the default profile.  If you ignore the bed size values.  There must be some reason whoever submitted them to Prusa did that.  I'd still be starting with the default as a basis and modifying that rather than a complete start from scratch custom.

What will be much different though are the PRINT profiles.  Its those that define extrusion width, overlaps etc.  Did you compare those ?  Even the filament settings (although I just took the default PLA profile that comes with that printer profile).  

Whatever you do its going to take you time to nail it down, I've just gone through the same with my Neptune 3 Max.  Luckily I've done this several times before 🙂  Which speeds things up. 
That's why I say getting the basics down like confirming the extrusion rates and steps per mm on the extruder etc need to be correct before you can look at why your infill is not quite getting to the perimeters.  Also physical movement on the axis, so confirming that when its told to print a line 20mm long it actually does print 20mm long.  

The first layer being correct isnt really a slicer function, it's a physical calibration function and I don't even contemplate doing anything beyond a single layer calibration print until that is dialled in.  Yes it can be effected by putting something really out of whack into the Print settings>first layer extrusion width and first layer print speeds but if you start with something sensible in there to start with and get it properly levelled and set then everything that comes after is not effected.  

It's only after I 'know' those are right that I would move on to something like your disc or a calib cube or similar.  Actually after that I'd do the single wall cube to check extrusion widths, accurising my filament settings to get extrusion set properly.  At that point I would be confident that the physical x/y and extruder output was ok.  I would then move on to checking dimensional accuracy in x/y/z.  After that I would start on setting retraction values etc and seeing if there were any other problems.  Step by step, building on the previous ones.

RE: Need help dialing in Prusa for Ender V2 Neo

I think the problem is I'm comparing the two completely wrong. Other than loading the two into PS I don't know how to do it.

If it's not obvious yet, I'm pretty new to CAD and 3D printing. I'm only at for 7 weeks. I'm relying my experience in coding since the Commodore Vic 20 and the fact that I've been a graphic artist since cut and paste was when one would use an exacto knife to cut and wax as an adhesive.
