Cura 3.6 Slicing Bug

[nobio8 2]

I printed Delta Calibration tool and the print has a Geometry error

as seen from Picture of Repetier Preview (Red Arrow pointing at error)

Cura shows Preview as it should be sliced.

I attached GCODE, Cura profile and Repetier Preview

DEltaCAl.gcode ASA 1.curaprofile

Hi @nobio8, could you please save the cura project (.3mf) file and attach that.

here it is 

Cura error.3mf

I just slice another Calibration Tool 

and error apears in the same territory

I agree, there's some very odd gcode in your file. Here's a comparison between what you are producing and what I get when I slice the same project.

 

 

 

And here's the gcode I got...

 

 

 

CFFFP_2036387790_Curaerror.gcode

I prewied your GCODE in Repetier and it looks OK

Then I used the same Cura 3.6 profile in Cura 2.5.1

and at firs glance Model is sliced correctly, so there must

be something going on with 3.6

If you want to try my release, you can find them here...

Oddly, when I sliced his original file in 3.6, this is what I got. I co not see the weird errors shown above. Or, it is just too early in the morning and I cannot breathe.....😜

smartavionics I sliced it again with your version of Cura

and both Previews, Cura an Repetier's are the same no slicing

error.

I also imported my original GCODE (attached to my post)

back to Cura 3.6 and preview shows errors correctlly.

To summarise :

1. 3.6 sliced my model with errors which are not visible in Cura preview

when slicing

2. If we preview GCODE in other slicers error is visible in all of them

3. If we import the same GCODE back to Cura 3.6, preview shows errors

as all other slicers

 

We have two problems:

1. Slicing with Cura has major errors

2. We can not relay on Cura to preview the code correctly

unless we import the G Code back again

Have you tried the 4.0 beta? Perhaps the problem has been fixed since 3.6?

I am curious to the fact that I am not seeing these issues on my 3.6 installation.

 

Here is the G-Code.

CFFFP_2036387790_Curaerror.gcode

 

This is also what I did when I went in and 'fixed' my installs (3.6 and then 4.0 beta 2)

 

I was having issues with my Cura. I killed all setup files, all Cura files and folders and did a fresh install of 3.6. I only installed 4.0 beta recently. During 4.0 beta I told it to not uninstall anything.

sorry for delay, I solved the problem by the following procedure

1. saved my Cura profiles and materials

2. removed  all Cura installations

3. Reinstalled Cura 3,6

4. Imported back my Profiles

 

Now it seems everything is just fine

That is good to hear. 🙂 I wondered if that was why it sliced well for me. Seems to be the answer. To me then, this points to an upgrade issue with Cura?
