Two on the X-axis and two more on the Y-axis. Before turning the printer on, they must be removed to allow the free movement of the axes. These are added by our technical service to block the axis during transportation and to prevent the misaligning of the parallelism of the printer. - Check where the belt clamps are located according to each BCN3D printer. | [![Epsilon-header](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Materials/Epsilon-header.jpg?width=600&name=Epsilon-header.jpg)](https://support.bcn3d.com/knowledge/remove-belt-clamps#epsilon) | [![epsilon w27 header](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/epsilon%20w27%20header.png?width=600&name=epsilon%20w27%20header.png)](https://support.bcn3d.com/knowledge/remove-belt-clamps#epsilon) | [![sigma d25 header](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/sigma%20d25%20header.png?width=600&name=sigma%20d25%20header.png)](https://support.bcn3d.com/knowledge/remove-belt-clamps#sigma25) | [![Sigmax-header-3-prints](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Materials/Sigmax-header-3-prints.jpg?width=600&name=Sigmax-header-3-prints.jpg)](https://support.bcn3d.com/knowledge/remove-belt-clamps#sigmax) | [![sigma r19](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Related%20Articles%20Base/sigma%20r19.jpg?width=688&name=sigma%20r19.jpg)](https://support.bcn3d.com/knowledge/remove-belt-clamps#sigmax) | | --- | --- | --- | --- | --- | #### To remove the belt clamp, hold the belt first and remove the piece. ![remove the belt clamp x epsilon](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/remove-the-clamp-x.jpg?width=688&name=remove-the-clamp-x.jpg) ### Epsilon Series When unboxing the Epsilon printers, you will find the belt clamps located in the following way, substituting the lathers that used to hold the printheads. | ![belt clamp x epsilon](https://support.bcn3d.com/hs-fs/hubfs/Knowledge%20base/Draft/belt-clamp-x.jpg?width=688&name=belt-clamp-x.jpg) | ![Belt-clamp-Y-epsilon-series](https://support.bcn3d.com/hs-fs/hubfs/Belt-clamp-Y-epsilon-series.jpg?width=336&name=Belt-clamp-Y-epsilon-series.jpg) | | --- | --- | -
