Z stage problems in assembly

Recommended Posts

When I initially installed the Z stage the 12mm steel posts/axes would not both go through the the linear bearings in the tray and the holes at the bottom of the printer floor.

There was a 5mm difference between the distance between the axes holes in the printer and the distance between the linear bearings in the tray.

I loosened the bolts holding the tray together in order to be able to seat the axes into their holes however now the Z stage has separated at the rear and is in danger of coming apart completely.

See attached photos.

Have I just made an error on how tight these tolerances are? It seemed to me that if I tried to separate the axes by force into the bottom holes in the printer something would break.

Thanks in advance.

it is by design that the tray has no connection to the arms towards the back. this is to provide additional springiness towards the back, to get the same springiness as the front.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
