Cura "prints" ON the wall of the model


Recommended Posts

Posted · Cura "prints" ON the wall of the model

Hi everyone,


I'm new with Cura slicer, but made an almost good print on my hand made 3D printer. 
The donor of my printer was Geeetech i3 Pro C. Now it is Bowden type with extruder with 0.4mm nozzle from Aliexpress.

What is the issue: I make models with Solidworks on my work and want to print them exact as is possible.

I made calibration of steps / mm using an electronic caliper, so they are with 99.9% correct.

Yesterday I made some prints, the quality is good enough for PETG, but the dimensions are not correct.

The outer dimensions are a little bit bigger, but the INNER dimensions are much smaller than they must be.


Outer dimension have to be 40 mm, it is 40.18-40.2
Inner holes MUST be:
- 8mm , it is 7.48 - 7.54
- 24mm , it is 23.68 - 23.72
- 3mm , it is 2.68 - 2.72

I start to think that Cura puts a filament ON the walls of the model instead ot IN the walls.

You can see my settings and the result.

Any advice will be appreciated.

Thank you in advance.
