Dimensional calibration

[Uldis 0]

Hello guys, I have recently realised the X - Y dimensions are off.
Something that should have been 170mm is in reality 172mm (on the bed) when measured.
How can I calibrate my printer so it corrects this?

Well, you asked in the Cura section, so...:

 

Cura has no functions to do any calibration of printers.

But you can use the scale tool to change the size of the loaded model.

In addition: most printers allow to change the steps/mm (per axis) with a gcode command. You can add such things to the start script in Cura if you want. The exact command and the parameters are depending on the printer and the kind of firmware it runs.

 

Hope that helps!

Thanks, I guess it gets more complicated with having a Delta printer, as there steps/mm is not a single stepper motor thing, but a combination of them all...

On a cartesian printer you have to set the steps per mm correctly. On a normal printer these can be calculated from the properties of the stepper-motor, the pulley, the belt and microstepping-settings.

On a delta printer you also have to set delta-radius and rod-length correctly, which can be quite complicated.
