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

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

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 https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0&lst=

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

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

In experimental section, tick box labeled 'make overhang printable' or play with the tree support option

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 ;LAYER:597 M204 S1800 M205 X8 Y8 ;TYPE:FILL ;MESH:Centoculops_Posed_3DPrint.stl G92 E174.18367 ;set extruder to last position G0 F600 X77.476 Y129.528 Z119.6 ;move to start of new layer G1 F2400 E180.18367 G1 F3000 X118.565 Y73.979 E180.30606 G1 X118.591 Y73.973 E180.30695 G1 X118.962 Y73.93 E180.31937 G1 X119.366 Y73.942 E180.33281 G1 X119.682 Y73.997 E180.34348 G1 X119.998 Y74.092 E180.35446 G1 X120.246 Y74.196 E180.3634 G1 X120.465 Y74.323 E180.37182 G1 X120.476 Y74.331 E180.37227 G1 X116.042 Y78.765 E180.58084 G1 X116.157 Y78.971 E180.58868 G1 X116.297 Y79.159 E180.59648 G1 X116.488 Y79.353 E180.60553 G1 X116.691 Y79.514 E180.61415 G1 X116.993 Y79.7 E180.62595 G1 X117.2 Y79.794 E180.63351 G1 X117.258 Y79.811 E180.63552 G1 X121.324 Y75.745 E180.82677 M204 S3000 M205 X10 Y10 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🤞

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

select object and then cntr M

What does the generated g code look like after you slice using this start code ? seems ok when i test it.

this is with bottom layers set to 0

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

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 M190 S{material_bed_temperature_layer_0} ;Wait for bed to reach temp before proceeding M109 S{material_print_temperature_layer_0} ;Wait for extruder to reach temp before proceeding

Try M140 S25 #cool the bed to 25 °C M190 S25 ;wait for bed to reach target temp G0 X160 Y125 #move "behind" the model G0 Z10 #move down G0 Y0 F2000 #push the model out #The rest is c/p from the begining of the print M140 S85 #heat the bed to 85 °C M106 S1 M204 S2812 M205 X18 Y18 ;MESH:Object 34 G0 F6180 X158.075 Y28.465 Z0.42 M204 S750 M205 X7.5 Y7.5 ;TYPE:WALL-INNER G1 F1500 E51.96984

R-clik a stl, clik properties, clik 'change' and choose cura.exe

have a look in preferences/general/opening and saving files

manual d/l

put these 2 lines just after the G28 M190 S{material_bed_temperature} ; start heating the bed to what is set in Cura and WAIT M109 S{material_print_temperature} T0 ; start heating hotend to what is set in Cura and WAIT

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).

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 . http://files.fieldofview.com/cura/Replacement_Patterns.html try something like M104 S{default_material_print_temperature} ;heat nozzle to default temp set in material settings M140 S{default_material_bed_temperature} ;Start heating bed M190 S{material_bed_temperature_layer_0} ;Wait for bed to reach temp before proceeding M109 S{material_print_temperature_layer_0} ;Wait for extruder to reach temp before proceeding

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.
