Quick question about fit
Posted: Thu May 22, 2014 9:27 am
I noticed last night that the top and bottom of my base assembly is not 100% perfectly mated to the vertical support bits. I think what is happening is that there are small variances in the height of the laser cut parts so some of them might be a tiny amount taller than the others. What I saw was that when I tightened down the screws that hold the top part of the base on that in some areas a tiny separation would form between the vertical support and the top plate. I mean a separation about the thickness of a piece of paper.
I could see the separation most obviously at the midpoint of the vertical support parts between the two tabs that insert into the top of the base on each of them. It looked like a tiny amount of bowing of the top of the base. What I did was to slightly loosen the screws holding the base top and bottom to the vertical parts, and it pretty much went away.
Is this perhaps why a few people have trouble with calibration? I noticed that then the top was bowed that it could flex up and down if I pressed on it. I could close the gaps by pressing the build surface down. I would guess it moved by the thickness of a piece of paper.
With the screws backed off it seems to have improved significantly. But now I'm worried the pieces are not attached firmly enough and the whole machine will flex.
Perhaps I am over-thinking? Anyone have any advice?
