Dome and Body Alignment issue
#1
Hey so i seem to have run into an issue with the dome and the body

The dome and the dome rings are all the same size, But the body seems larger than the dome, just putting the dome on top i can see the dome sits nice at the front but at the rear it sits almost over half a cm inside the body. Pics should help explain.

Front ligned up nice

Rear Mis-aligned

Everything has been printed the same, and i used all the alignment holes..... at a bit of a loss.

I haven't finished printing the body, but the dome does appear to be smaller in diameter than the ring3 body.
I was thinking at this stage, since my prints arn't yet finished, the dome sat slightly inside the body...

Okay, so using my brain a little bit, i have seemed to solve the issue, as i just finished gluing ring 3, and attaching ring 1, 2 and 3 together with 2 part epoxy with a full cure time of 16 hours.
Sooooo as ring 3 sets, and ring 1,2and3 set i got some tie down straps, clamps and went to work lining it all up, and it seems to be 99% better!!!

I'm having the same problem that you are, but I was thinking the issue was due to the fact that i'm a little bit behind where you are and only dry fitting things together. But, now I'm thinking maybe it's a bigger problem than that... so, what exactly are you doing here?

well i looked at phul07 build and when he did the body, the upper body ring sat nice and flush with the outer lip on the third ring. 
so i just glued it all together (except for the utility arm frame and the dataport, they are just sitting there because i have to paint separately) and got some tie down straps and tightened the front to back and the side to side, so that the upper body ring sat nice and flush until the glue dries.. Not sure how everyone else is getting it done, but that was my solution.

Glad I could help lol, Yeah plastic will move around so measure and use clamps to hold when gluing together.

Best of luck

okay so after more gluing and clamping im here, there is probably only 1 to 2mm size difference between body and dome, this i can live with. hopefully grabbing lazy susan today so can start making sure all the rings and gear rings etc fit together.

I had some issues with this too.

My 1st to 2nd layer alignment was terrible, and I had to put relief cuts through layer one and then glue and clamp it back together to bring it into shape.

My third layer to dome alignment is off by a few mm, and I think I am just going to ignore it, as other than the it is all already glued together.

I have bolted my top layer, lazy susan, dome, etc all in without having too much trouble getting bolts through holes so my alignment isn't too terrible.

yeah i havent bolted the body top ring onto the body yet. So i assume once the glue sets on mine and i sort out the lazy susan and body top ring, once i bolt/glue the body top ring onto the body that will pull it all together. good to know im not the only one contending with this issue. seems solvable tho. like you said, a couple of mm is no big deal.
