BTW, what works for me is splitting the sphere in three parts: the bottom part is printed in normal mode with a bottom thickness of 0.8 mm applied, the middle part is printed in surface mode and the top part is again printed in normal mode with top thickness 0.8mm. The top and bottom part have +0.2mm horizontal expansion to compensate the thickness of the surface wall.
However, this is a pretty crude method- I'd certainly prefer Torgeir's method where you don't need to split the model.
thanks for your hard work - that looks great, in deed! Now I just need to reproduce that over here, somehow 🙂
By chance, do you got any hints why Cura detects the surfaces properly when the Sphere is created with Fusion360 but not with MoI3D?
Anyway, I guess I need the Arachne Beta slicer - with stock Cura 4.10.0 I get the result as seen in the attached screenshot when opening and slicing your 3mf.
There was a problem with Cura detecting the inner wall.
So I made this sphere in Fusion 360 (Autocad free version) Just 20 mm diameter and strait hole dia. 8 mm.
The wall gradually increased from approx 70 deg. (0.4 mm to top 0.8 mm) and same at the bottom.
Seems to be possible to print, but not sure how it will be.
Here is a picture how it's looking in Cura Arachne Beta.
Here's the your project file from Cura Arachne Beta;
And the gcode, but have not checked this one..
On my UM3 , a day or so ago it started 'grinding' filament rather than pushing. It is the same roll of PLA (i have not tried another roll).
The tension is set in the 'middle', and I have cleaned the knurled steel pully a couple of times and it will properly load the filament but
will not push enough to print.
I thought the nozzle might be clogged, but I cleaned it and it flows freely when putting it in there by hand.
I am considering replacing the feeders with Bondtech, but I hate to go to the expense (personal use, not commercial) on
retirement type income.
Greetings Im new to this.
Can anyone advise, is it OK to leave additional components outside of the build area or are there downsides to this?
My reasoning is build the first item, then move it out of the way then move and build the second item?
