I have broken my interlock on the z axis

I was trying to drill and tap the nib on the interlock for the Ridged router z axis to make it simpler to prevent it from pivoting. I also desired it to be simple to disengage so that I can pull the spindle easily. The pot metal shattered leaving a cradle for a conical wedge (otherwise known as a wire nut :wink:). I used a large zip tie all the way around the interlock mechanism and used a small screw to secure it from slipping. The screw may have also tightened the wedge. I am glad I have managed to get the stock z axis to make it this far but don’t know how long it is for the world.

What does it take to completely redo the z axis? Build? Settings? Calibrations? I’m intimidated :fearful:. Also… What’s going on when measurements don’t match from cam to reality?

If you want to just replace the parts with original design this company has most parts at reasonable price.


The other option you have is to upgrade the Z axis. There are a few designs out there (I am building the Meticulous Z design currently). They are not quick fixes as you have to wait for shipping (if you don’t want to spend a ton of $).


order multiple parts at once, especially the orange buttons. the parts are
cheaper than the shipping in many cases, so get spares.
