Simplify3D User Forum

Firts i have to say hello to all board uses

I am new here in the forum and i hope somebody could helt me to fix my problem.
I have a mendelmax 2.5 printer with the simplify3d slicing and printing software.
I print since about 4 month but i startet two weeks ago with the simplify3d software.

I pring mainly technicial parts.

So my problem is that i have a space between my outher wal of some objekts. The strange thing is that in one model i have sometimes on the right side a 0.3mm space in a 2mm wall.
i adjusted the extrusion with to 0.49mm and normally i have then 4 lines for an 2mm thick wall... On the slicing software it also show the 4 lines but on the printed part they are missing....

And the second problem is that the Top layer does not look very nice (

Noozle dia: 0.5
multipler: 0.92
extrusion with: 0.49
Solid/Top layer: 4
Outher perimeters: 4
Infill: 30%
first layer high: 90%
retrac: 1,2mm
coast at end: 0.4mm

many thanks in advance and best regards from Austria/Europe

If it shows 4 lines in gcode preview then the gcode is being produced to print the 4 lines and that is how the printer should print it. Are you sure you see the 4 lines in the preview? Another way around this is to set perimeters to 1 then turn up your infill a little. Your top surfaces probably don't look good because you have the ext width set smaller than your nozzle. Set that back to auto or a manual value that is higher.

Hey jimc

Thanks for very fast answer.
I will test the settings today
I think the "manual extrusion with" is the key... In the meantime i found an fail in the drawing i get from my cad drawer... That was the reason why i set it to manual...
But in the meantime i get repared cad drawing and i forgott to change the manual / auto setting.


I will report after the test here in forum.
Thanks to all

Hello

After a nice printing weekend i think one of my problems is fixed !! Thanks to jimc !!

First i removed my nozzle. Then i let extrude the extruder 100cm of filament. Then i measured again and correct the motor Steps until 100cm extrusion are 100cm real filament.
Befor i calibrated with 100cm i always calibratet with 10cm but i think that is not correct enought for me beacause may parts all need between 60 and 100 meter of filament.
When i compare the 10cm and the 100cm extrusion, bettwer sayed after the 10cm calibration i was wrong about 4cm when i extrude 100cm !!!
butr now is correct )

Then i make an cube with 25mm x 25mm outside. I make no infill and set the extrusion with to 0.5mm and i start printing....

After that i correct the extrusion multiplikator until the 0.5 are 0.5 measuered.

Then i set one outer parameter and 40%infill and 4 top and solid layers with layer hight 0.3mm

And that is the result !!!

But as you can see in the last pictures i have some blobs in my part..

maybee anyone has an solution for that problem ???

My settings are:
Primary extruder:
Retraction distance: 1,8mm
Extra Restart distance: 0.00mm
retraction vertical lift: 0.00mm
retraction speed: 1800.00 mm/min
Coast at end: yes
Coasting distance: 0,4mm

infill:
Interior Fill percentage: 40%
outher overlap : 15%
minimum infill lenghth: 5,00mm
print space infill every : 1 layer
use infill placement: yes


i will be nice if anyon could help to fix my last problem )

thanks for all best regards from cold Austria

Here the missing pics

Turn the wipe feature on to tue default 5mm and slowly raise the coasting up until that goes away. Also make the layer start point begin from a specific location. Make that spot a corner of your box.

Hy jimc
Thanks for answer... I will test the settings today and i tomorrow i can post score

From yesterday until today i printed the maker torture test and here is my part....

It looks ok but not good !! I think it will be much work until it will look perfekt.

By the way jimc... Very nice Homepage and very very good painting and customizing work !!!! Amazing !!!

I printed this test with 3600mm/min speed and the same settings like the first part...
Now i change the settings to 2000mm/min, wipe on...

And the last three pics with old settings
