I think i spotted 2 problems,
At the ed of the start G-code it should be G92 E0
And i think in the extruder start G-code you need a G90 after the G1 E110 F3000
-
When i try and download the zip, it just takes me a site that wants to install some random 3rd party software, could you post the zip somewhere else
-
Not sure if reprap gcode is different, but if you go into manage printers/machine settings there is a option to choose the gcode flavour.
-
It may be the walls are very thin.
Make sure you have 'print thin walls' ticked when you slice it
-
On the top left, click settings/configure setting visibility, then tick the 'check all' box.
now under 'support' check the value you have set for gradual support infill steps.
-
Tick 'print thin walls'
Set 'outer wall inset' to -0.15
should slice ok.
-
Could the holes be caused by moisture in the filament, do you hear any popping noises while printing ?
-
You need to put the bed and extruder placeholders in the machine start Gcode
eg
G21 ; set units to millimeters
G90 ; use absolute positioning
M80 ;power supply on
M104 S{material_print_temperature_layer_0} ; set extruder temp
M140 S{material_bed_temperature_layer_0} ; set bed temp
M190 S{material_bed_temperature_layer_0} ; wait for bed temp
M109 S{material_print_temperature_layer_0} ; wait for extruder temp
G92 E0.0 ; reset extruder distance position

pls save the project and attach the 3mf file
-
So i made a 11mm box and sure enough when i sliced it at 0.2 layer height it had 54 layer(which equates too 10.8 mm)
The only setting i could find that effected this is the slicing tolerance, exclusive gave 54 layers, inclusinve gave 56 layer, middle gives the correct layers at 55.

Unless you have changed it in config.h, marlin sets the max extruder feedrate to 25mm/s
#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
-
I found meshmixer easiest to use for this, just copy n paste each part to a new stl
-
I can find no problems with the project file, slices and prrints ok in cura 4.0.
Have you tried re-slicing the object ?
-
Would help if you could save the project file and post it here

/**
* Default Max Feed Rate (mm/s)
* Override with M203
* X, Y, Z, E0 [, E1[, E2[, E3[, E4]]]]
*/
#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
The above is from Marlin configuration.h
It seems Marlins default max feedrate limits the extruder tp 25mm/s
Try sending A M203 E50 and see if it allows you to go faster.

In the experimental section of the settings, select 'slicing tolerance' Exclusive
-
I also have 'no' rotate option in the marketplace, i DO however have a rotate button on the left hand tools bar.
Silly question, but you do have a stl loaded and have clicked on the object.on the bed ?
Dont shoot me down if i have stated the obvious :)
-
I guess this is a 3dlabprint model, these stl are single line (no wall thickness) i found there are several cura settings that will prevent the iner structure from being sliced, mainly slicing tollerance that needs to be set at 'exclusive' and surface mode set as 'both' there are others also.
I have attached a cura 3.6 profile that i use to print these planes
hope it helps

5 hours ago, Smithy said:
Don't work if the bottom is not flat, so you have to lower the object in the bed to get a flat bottom.
Agreed, but clicking 'lay flat' on this particular object flips it onto the other face, which allows you to print it ok.
-
select stl then click the 'lay flat' button in the rotation tab on the left. sorted it for me.
-
Try setting 'support X/Y distance' to 0.0
-
is this what you want ?
-
Change 'skin removal width' to 0.6

Where do you set nozzle size in 4.3?
in UltiMaker Cura

Try preferences-printers, select printer then machine settings-extruder
