Any one know how to get cura to do thin walls. Im trying to print a square with .04 walls to calibrate.
0.04mm is way too thin for any current FFF printer. Plus, the actual extrusion width is always larger than the nozzle size, so try around 0.5mm for a 0.4mm nozzle and see if that works.
Sorry yea I’m shooting for 0.4
What exactly are you trying to calibrate by printing thin walls? There used to be common calibration methods that called for this, but they were based on flawed assumptions and methodologies.
Tell Cura you have a 0.2 nozzle.
Im trying to get my holes more accurate. Right now 3.45mm holes are showing up as 2.6 or so
Try @nop_head 's polyholes (OpenSCAD module) and/or KISSlicer’s “inset surface” or Slic3r’s “XY Size Compensation”.
A difference that big is probably (at least partially) slop in the axes.
The weird thing is for solid objects say a cube the dimensions come out very close to spot on
Use the solid-box-without-infill method. Everything else will get improper results with Cura.
I’m also no fan of the 0.4mm wall calibration, I think it’s a flawed method. I’m more of a “extrude 10cm material, see if it’s really 10cm” kinda guy.
Also, if your holes are that much off, you are more likely to have backlash then something else. As that’s the main cause for lots of inaccuracies in my experience.
Currently its set to the calculations provided by the prusa calculator.
Ok so I did a solid 15mm cube with 0% infill and 0.45mm wall thickness.
It came out to exactly 15mms edge to edge measured in the middle of the cube.
Walls came out .45mm thick.
So that’s all close enough. Im still getting some bulging at the corners which may be why holes are off as they are all corners.
Any thoughts?
Most likely you are printing too hot then.
Im running pla at 180c
