Hello and thank you for choosing the Creatr HS for your printing needs.
If you hear strange noises on the Y-axis movement of your Creatr HS there are several things you can check:
1.The first one is to check the bearings and see if the noise originates from there. You can resolve this by applying silicone grease on the Y rail the bearings move on and then move the assembly until the bearings get lubricated.
2.The second option is to check the belt tension on both sides and adjust it by loosening or tightening the screws until you get similar tension in both belts:
Thank you for reading the solution and for any other issues please do not hesitate to contact our Leapfrog Support Team.
We wish you happy printing!
