Dimension errors Ender-3 Pro | Model Engineer : vimarsana.co

Don t have direct knowledge of the Ender Pro 3 but most 3D printers have fine tuning to get measurements correct. This All3D Article on calibration may help. It is also likely that there are firmware tweaks that will alter the distances travelled in X and Y these may be well buried in the on-board system and essentially tune the stepper motors. Setting the Z axis can be difficult as the layer height is pretty well fixed so everything is a multiple of this and of course the 1st layer will be slightly under height to get good bed adhesion. Z is perhaps best dealt with in the slicer (Cura) where a suitable multiplier can be applied to end up with the correct height.
