Printing scaling off. (Newbie)

[Singularity9823 0]

Good evening everyone, I hope everyone is doing very well.

 

I have an Creality S1 pro printer and am printing with White PLA. My settings are default on the printer itself with the heat-bed being 60 degrees and the nozzle being 200 degrees. Within Cura I am using Dynamic quality currently and use the grid fill option. My prints are currently 20% fill. I did level the bed and set the Z offset of the printer.

 

After printing my XYZ calibration cube and using calipers to measure the cube, the dimensions were exactly the same on all sides, but the actual size was completely off. The calibration cube should have been 20.00 by 20.00 by 20.00, however my results were Z: 1.79 X: 1.79 Y. 1.79.  this is a massive difference, and I've not seen anywhere on YouTube anyone with less than 18 or higher than 21-22. Right now I am printing a Benchy, but it also seems much smaller than it should be. 

 

What could be the cause for this? Could it be the firmware that needs to be updated? or should I recalibrate the printer through Gcode as indicated in this video?: 

 

(I wanted advice first before proceeding, as I am a bit afraid I might F up the printer, as I am very, very new to 3D printing)

 

Any help is greatly appreciated guys.

The printer is supposed to go where it's told but if the printer-processor is told to go 25mm then it sends "steps" to the motors to move them.  How many "steps/mm" comes into play.

The first thing to check is the gcode.  Open that Calibration Cube gcode file in a text editor like Notepad.  In the first few lines is the Max and Mins for the three axis.  The max and min XY will include the skirt/brim, but the MaxZ should be 20.00.

Typically, the X Y and Z steps don't need any adjustment, but maybe yours do.

(You said the printed cube was 1.79 on each side.  I hope that was cm and not mm.)

lol yes, CM, 1.79 CM. XD imagine that was millimeter! PAIN lol! 

 

Thank you, as soon as my Benchy print finishes, I'll check the Gcode on the file and report back.
