Graber i3 Day 5: Leadscrew
Tiny steps today! @Shane_Graber Is the nut just glued into the x-carriage?
The M5 nut doesn’t need to be glued into the x-idler and x-motor. It’s sandwiched between the top plate and the plate with the hex shape cut into it. Use the holes to hold the top plate on with an M3 screw/nut.
Sandwiched, hm… The hex shape in the plate is bit bigger than the nut. There is noting to be clamped…
Well you have it right in the photos…
Are you asking about the x-motor and x-idler ends or the x-carriage?
looks good
Kurt, thanks a lot for the photos - they are a great help to me, who has absolutely no knowledge of printer building and tries to make it right the first time 
@Shane_Graber Now I know what you mean. My problem is that the hex shape is cut completely through the plate. That means no chance to clamp the nut. 
I should have paid more attention to this point when I prepared the vectors for the lasercut.
So I glued the nut to the top plate and hope it works anyway.

@Igor_Larine You’re welcome. But i guess you will fail if you try to make it right the first time.
I am trying at least to make sure it’s cut right And since I am modifying it all for M4… Speaking of your latest photos were the ones that saved me from redoing the whole X axis assembly! You can’t imagine the frantic Sketchuping then converting and emailing, only to find out that the shop guys are lazy and have postponed the whole thing till Monday. Btw they were saying the same thing about these nut cutouts - laser power is such that if made to the whole depth of 3.2 mm out of 6, the charred remains will fall out.
OK, I see 
There are other problems beside the hex shaped cutout…
I had the same problem with mine, but wrapped some masking tape around it and pushed it into the hex cut out.
