z lifting after skirt??

Hey all,

I have the 1.0RC2 version installed and noticed that Z seems to lift after the skirt prints.
This means the first layer sucks..

Thoughts?

Thanks,
Ash

Go to Printer setting/ Extruder 1 and make sure the "Lift Z" under retraction is set to -0-.

I have been using RC since the day it was released with no issue of lifting.

Ill check that, but have been using Slic3r for a long time now and never encountered the problem until now.
I have spoken to another user who has observed that the skirt is noted to be "layer 1" and then the first part of the job "layer 2" - this appears to explain what I am seeing, but still no idea why..

I just checked the last 5 items I sliced with R2 and the part starts on layer 1 as does the skirt.

Now one weird thing I have seen is with support on, sometimes you get say support on layer 3 then object on layer 4 then support layer 5 object layer 6 and so on and there was a mention of this elsewhere in the forum as well. So, are these prints with support turned on?

So I have confirmed that "Z Lift" is off. (I never use it)
I have also confirmed that skirt is layer 1, and the first print layer is 2...

Here is the first few layers of a 20mm test cube.

That looks really weird and not normal.
skirts is fine , but object starts at layer 0.6 so 2 first layers are missing.
You may add testfile (STL) and slic3r settings here (export config) for verification.

Phew! Glad im not going crazy.
See the attached files.

Thanks.

Now you can go crazy again...
I loaded your stl file into slic3r with my settings, no problems.
I loaded your config file into slic3r and sliced again..
and guess what....no problems to be seen. You may see attached screenshot from Repetier.
I have no clue...

Your uploaded config file is not a complete ini file, did you export explicitly? I do not know whether this could influence my conclusion above :-(

I'm new here, I found this forum while researching my problem.

I have the exact same problem, with support turned off, (for a part that doesn't need support) the skirt is on the first layer and the first layer of the part itself is on layer 2.

Also I have the other problem that was mentioned : on a part that needs support the support material is on the odd numbered layers, then the part material is on the even numbered layers.

Slic3r version is RC2,
lift Z is set to 0.

You do not give us any information so how can we guess if your problem is the same?
Upload your stl and exported config file at least for anyone to look into

Very, very odd. Thank you for testing BTW.

I may try a complete reinstall of Reptier/Slic3r. I have been using it for a long time and have upgraded several times.
I also manually copied the new version of Slic3r into the Repetier folder. (not that it should cause a problem)

I will let you know how it goes.

UserZero, could you upload as suggested?
It would be great to have another example of the problem.

Sorry, regarding the G-Code I posted.
No I just copied the first sections from the editor, as only the first few layers are affected.
I can post the full code if required.

Could you try to run Slic3r standalone without Repetier, that is what I am doing?

That attached .ini is not the same as shown in your partial gcode list above it.

Here is the top of the gcode produced by your uploaded .ini file that shows settings

; layer_height = 0.2
; perimeters = 2
; top_solid_layers = 1
; bottom_solid_layers = 1
; fill_density = .2
; perimeter_speed = 20

Upload your stl and exported config file at least for anyone to look into

You're right. I'm sorry!

Last night I tried to slice a sample object with and without support and/or skirt in order to upload the required files. As I tried to replicate the problem Slic3r behaved rather erratically, I tried changing the parameters in the configure window and it wouldn't save the new config, even after trying repeatedly, I eventually found out that increasing a setting by only one increment would cause the software to not save the settings, So for example if I tried to set the skirt height from 1 to 0, it wouldn't save unless I first set the height to say 5, then save, then set to 0 then save again. Then I sliced the part and the skirt AND the first layer of the part appeared correctly on the first layer of the slice as it should. So now I can't replicate. I still have the problem with the support material showing on alternate layers though. I'll post my files on the thread about that specific problem tonight.

Just for background I am running Slic3r 1.0.RC2 from within Repetier, on a Dell 6510 laptop that can handle complex parts in Solidworks without any problems. I used to be able to print real good before, so I assumed the new version of Slic3r was the culprit.

Thanks for your time guys, sorry I wasn't smart enough to document the problem when it appeared.

Georges

Phew! Glad im not going crazy.
See the attached files.

Thanks.

That attached .ini is not the same as shown in your partial gcode list above it.

Here is the top of the gcode produced by your uploaded .ini file that shows settings

; layer_height = 0.2
; perimeters = 2
; top_solid_layers = 1
; bottom_solid_layers = 1
; fill_density = .2
; perimeter_speed = 20
; infill_speed = 20
; travel_speed = 75
; nozzle_diameter = 0.5
; filament_diameter = 3
; extrusion_multiplier = 1
; perimeters extrusion width = 0.50mm
; infill extrusion width = 1.02mm
; solid infill extrusion width = 0.85mm
; top infill extrusion width = 0.85mm

Yep you are right.
I am starting to think this problem, and my other (slic3r not saving settings) are the same issue.

This is definitely the same problem, thanks for posting.

for some reason I run into this same problem with a printed object.
I have no support activated and did not intend to have any raft either.
Skirt and brim was activated and some customized init code did some wiping of extruder.
So what happened was :
initial wiping code was (by repetier shown/printedas layer0.
Skirt and brim was shown (printed) as layer1 but layer1 from object disappeared !
layer 2 was printed in the air as layer 1 had gone with the winds.

Some investigation showed that raft was activated (>0) but no raft was printed.

If raft was set to 0 layers, object was printes as intended. If set to >0 first layer disappeared but brim and skirt was printed as layer1 and no raft was ever printed.
I cannot see why, and do not know if raft settings has any influence of why raft was not printed first place.

Another error with settings appeared here as well, as under some circumstances settings (raft layer here) cannot be saved without some manipulation described elsewhere when inc/decremented.
