What are misaligned prints and why this happens

When printing a dual print with an IDEX printer, sometimes, you may spot that the different materials are not aligned.

 

This is majorly a calibration issue in the X and Y axis. It can also be a hardware or firmware issue, but it is far more unlikely.

 

How to fix it

1: Calibrate both printheads in the X and Y axis

This is what you should do first once you spot this issue on your prints. Go to Utilities/Calibration/Printer calibration and follow the steps in the display of your unit. These articles will help you reach a perfect calibration:

2: Check the printer's alignment

After calibrating this should be fixed, however, if you find that the misalignment persists and it is in a specific direction, it is possible that you may have an issue with the alignment of the printer itself and missing steps. These articles will help you troubleshoot this:

3: Spotting hardware issues

If you are still having this misalignment, it is possible that your printer is not saving the calibration values. This is related to the mainboard, which would need to be replaced. Calibrate your printer and run a dual extrusion test. Here's a model that will help you in testing: BCN3D Boat

 

Once printed, turn the printer off, power it back up and then run the same test. If it comes out misaligned, the mainboard should be replaced. This article will help you in this:
