[Overhang Support???]

Thanks obewan and tinkergnome

 obewan your file wouldn't open. I did download Mesh tools and got the rectangular tube to be recognized. played around with different settings had it looking good tried to change infill density and it greyed out at 25 percent cant change it. wanted to lower it trying to get print below 24hrs. At 25 percent will be to heavy . What infill pattern would you recommend? Any thoughts??

 

Brian

did you try opening the file in cura ?

Infill needs to be set at 0% otherwise it will destroy your internal structure.

Print time is around 3 hours btw with single wall

[Overhang Support???]

try setting surface mode normal  and slicing tolerance exclusive, also make sure print thin walls is ticked.

But you do have some errors in the normals, In cura,top right, goto marketplace and download the mesh tools to show these errors.

I have attached the project file i use tfor printing the 3dlabprint files.

PI3_WR2.3mf

[User Specified Z Seam Alignment in Surface Mode]

Is this what you are after, allways starts the new layer at the start of the same line.

I sliced this with Burtoogle's cura build

[Saving slicer settings]

Load the stl, make all your adjustments then goto file/save this will save everything as a .3mf project file

[[SOLVED] Fixing a failed print with the missing layers]

dont forget to set the extruder value to the last Exxxxx from the previous layer otherwise you will extrude a heck of a lot of fillament

 

use G92 Exxxxx  at the start of your new code

 

[How to generate support ON the model ?]

In experimental section, tick box labeled 'make overhang printable'

 

or play with the tree support option

[Where to cut GCode in order to save a failed print?]

As a start, you can delete everything before the line 

;LAYER:597

The G0 lines are just travel moves to avoid crossing the print.

You need to set the extruder to the last E value before the layer change, so insert a lines

G92 E174.18367   ;set extruder to last position

G0 F600 X77.476 Y129.528 Z119.6 ;move to start of new layer

 

just before G1 F2400 E180.18367

 

 

so you end up with

Now you need to somehow home the printer without knocking the print off the bed and get things heated up.

manually move the nozzle above 119.60 then start printing.

I think that should work🤞

[Where to define max speeds for new printer profile?]

If you update the profile with the current changes (* on profile name ) it stops the popup .

there seems to be an unwated ellement in the stl, see image

What does the generated g code look like after you slice using this start code ?

 

seems ok when i test it.

 

[Why Cura adds a floor and how to prevent it?]

this is with bottom layers set to 0

[Parts of support starts "mid air" a few layers in to print?]

Try with support placement set to touching build plate  and support pattern as grid

[Custom Nozzle in 4.4.1]

nozzle diameter is in 'manage printers/preferences/printers/machine settings/extruder'

you might want to put this in your start g code  after the cool down part also

Try

I found this entry through a net search and it should answer my question and does, except that after adding them my printer begins warming and printing immediately, no wait for warm-up. Do these entries need to be in a specific place? I put them at the beginning! Here's my start Gcode entries:

 

M140 S{material_bed_temperature} ; start heating the bed to what is set in Cura

M104 S{material_print_temperature} T0 ; start heating T0 to what is set in Cura

[Is there a way to auto-scale everything by 1.6%]

surly if everything is getting printed too small, wouldn't this be a problem with the x y z calibration of the printer towers rather than the slicer used. (might be talking rubbish here, but just an idea).

 

 

[Problem with spiralize in CURA 4.3.0]

No explanation as to why but

Switch 'surface mode'  to surface and turn off 'smooth spiralized contours' seems to work.

 

Cant seem to get a bottom layer to it tho.

Seems like the placeholder names have all changed again .

try something like

M140 S{default_material_bed_temperature} ;Start heating bed

 

M190 S{material_bed_temperature_layer_0} ;Wait for bed to reach temp before proceeding

[Cura 4.3.0 slicing bug?]

used the repair option in slic3r, now slices perfectly in cura 4.3.

Strange thing is, using cura engine in repetier host it sliced ok without repairing.
