Three M3 screws with M3 star washers and M4 plain washers clamp it in place. The flange of the E3D V6 is a bit thinner than a J-Head, so if you put it in the socket designed for a J-head it will go in too far unless you place an M8 washer in first.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-77795256473343236892017-03-20T19:16:58.952+00:002017-03-20T19:16:58.952+00:00How is the hotend attached to the wades block thou...How is the hotend attached to the wades block though?<br />For the J head hotend, it seems to be fastened by screws, if I'm not mistaken.<br />With the E3Dv6 there are no screws.
