i use the skirt to fine tune the Z height using babysteps so as to get a good squish for the 1st layer

Cura default measurments are set to mm. make sure inventor is set to export using mm and not inches

Make sure you set up cura as per plane prints P3 profile I get a perfect slice with print thin walls unchecked surface mode surface slicing tolerance middle all mesh fix options unchecked

try manage setting visibility and make sure 'check all' is ticked.

When i slice your stl in upright position it slices perfectly, using fine profile.

change support overhang angle =55

Under build plate adhesion called 'brim distance'

not 100% sure but it look like you are missing a } "machine_extruder_trains": { "0": "wanhao_d4s_extruder_0", "1": "wanhao_d4s_extruder_1" },

Also set surface mode to 'surface'

when i rotate the .obj file 1 half is not flat to the build plate (sitting a few mm above). To fix this, right clik the model and in mesh tools select 'split model into parts' (you may need to download mesh tools from the marketplace)

One way is use the support blocker tool and make the joint 100% infill

M201 X1000 Y1000 Z100 E2000 ; set max acceleration

Please attach a project file so we can see your machine settings (file/save) attach the .3mf

I think the lines on the lettering may be a bit too thin Try with horizontal expansion=0.15

cannot see a prussa mini option. choose custom fff and fill in the settings yourself

If you attach the project file (.3mf)it would help find the reason (file/save).

please attach the 3mf project file (file/save) we can the see all the settings

It will stop when it hits the endstop

Wow, what speeds did you set when you sliced it, from the simulation it looks far too fast.

make the changes then click the v right of the profile name then choose either update current profile or create a new profile

please attach a cura project file( file/save)

ok, try surface mode normal remove all holes ticked spiralize outer contour ticked (forces single wall)

why not just click on the model and drag it to where you want it.

select surface mode in the slicer settings
