Hey everyone, I am finishing up my mendelMax 1.5 and I am noticing that when I try to zero out my z axis, at the very bottom when I turn the motor, the rod is turning slightly, however, the extruder seems to not move for a few micro turns, then all the sudden kind of clunk down to the bottom and make up the lost turns. I am not sure what this is, but I have seen some use a spring solution in the Z axis between two nuts. Anyone have any suggestions? If I should try the spring solution, can anyone explain or point me to a link on how to do it? Thanks! https://reprap.org/forum/read.php?4,193065,193065#msg-193065 Tue, 08 Sep 2026 21:09:53 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,193065,194144#msg-194144 https://reprap.org/forum/read.php?4,193065,194144#msg-194144 REPRAP SQUAD Reprappers Sat, 23 Mar 2013 00:37:31 -0400 https://reprap.org/forum/read.php?4,193065,194088#msg-194088 https://reprap.org/forum/read.php?4,193065,194088#msg-194088

I found the video again for those that want to understand how it works: [www.youtube.com]]]> Knimrod Reprappers Fri, 22 Mar 2013 14:50:12 -0400 https://reprap.org/forum/read.php?4,193065,193373#msg-193373 https://reprap.org/forum/read.php?4,193065,193373#msg-193373 REPRAP SQUAD Reprappers Wed, 20 Mar 2013 14:02:25 -0400 https://reprap.org/forum/read.php?4,193065,193255#msg-193255 https://reprap.org/forum/read.php?4,193065,193255#msg-193255
I discovered that my x carriage was not 100% level on both sides, so it was binding on one side.

Once I got it exactly level, this stopped happening.


Thanks for your help everyone!]]> AVRkire Reprappers Wed, 20 Mar 2013 06:37:05 -0400 https://reprap.org/forum/read.php?4,193065,193221#msg-193221 https://reprap.org/forum/read.php?4,193065,193221#msg-193221 one side of the X axis is hanging up when the axis is being lowered? If so, then your bearings on that side are binding on the smooth rod.]]> waitaki Reprappers Wed, 20 Mar 2013 04:30:50 -0400 https://reprap.org/forum/read.php?4,193065,193182#msg-193182 https://reprap.org/forum/read.php?4,193065,193182#msg-193182 Knimrod Reprappers Wed, 20 Mar 2013 00:04:59 -0400 https://reprap.org/forum/read.php?4,193065,193135#msg-193135 https://reprap.org/forum/read.php?4,193065,193135#msg-193135
