Without the springs installed, I don't think the top nuts actually do anything at all, other than perhaps provide a bit more control / restraint to the Z-Axis motion.<br /><br />(Nice work on the Wooden Mendel, by the way!)Julian Hardyhttps://www.blogger.com/profile/12454804345885642079noreply@blogger.comtag:blogger.com,1999:blog-108699730814653894.post-60219252581134185952011-09-04T12:51:30.524+10:002011-09-04T12:51:30.524+10:00I left the top nuts out of my X ends completely- t...I left the top nuts out of my X ends completely- this way, if I do something stupid and my printer tries to ram the nozzle through the bed, it ends up just winding the Z nuts out the bottom of the X ends - inconvenient, but a far preferable failure mode to the alternatives.<br /><br />Gravity is mostly sufficient to bring my X axis down. When I get rid of my Z belt arrangement it should be ample. On the odd occasion where it gets stuck, I can push it manually back onto the nut, and this never happens during printing because Z only moves up!Triffid Hunterhttps://www.blogger.com/profile/11285832141131462463noreply@blogger.com
