Third party x, y,and, z steps on ender 3 v2

[hecc 0]

My Ender 3 v2 has some dimensional innacuracies I would like to fix, but I am unable to find the steps per millimeter controls in Cura. I printed a standart calibration cube, but the z and y axis wre scaled down by approximately a tenth of a millimeter,from 20 mm to 19.9. I am unable to find the current steps per millimeter.How can I fix these innacuracies in Cura?

Those things are not part of the slicing process - the firmware of the printer handles it on its own.

The slicing engine of Ultimaker Cura does not know or need this information - that's why it is not there.

 

I'm pretty sure, Creality printers are equipped with Marlin-Firmware by default - so it should to be to find somewhere in the printers own settings menu.

 

Good luck!

@tinkergnome is correct (as usual).  Within the menus of your printer will be "Control | Motion | Steps/mm" and you can enter new values there.  They will be temporary until you use "Save Settings".  You could also send (or put into a gcode file) "M92 X?? Y?? Z?? E??" to change one or more of the axes.  Use M500 to save settings.

 

An error of .1mm across a model indicates .05mm / side.  That is about 1/2 of a human hair.  The Steps/mm on the XYZ are very accurate and you shouldn't need to change them (the E is a different story).  To handle your dimensional problem you can adjust the Horizontal Expansion in Cura or increase the flow by a couple of percent.  If you cool the part the dimensions will get smaller and if you heat the part the dimensions will get bigger.  It's plastic.
