I was finally able to print X carriage for Prusa i3 after three failed attempt. Because the way this part is oriented on the hot bed (I believe it's for better structural strength for the stress points) it gets knocked down quite easily.
In my last attempt, I went crazy with the hair spray as if it's 1985, and started printing and went out for a lunch. I honestly expected to find another bird's nest made with plastic ramen noodle sitting on my desk right next to half way done X carriage knocked away somewhere. However, to my pleasnat surprise, it was completed! I think the extra hair spary hold up the part all the way... or maybe I should not be watching when it's printing..
Anyway, I'm satisfied witht he quality of the print in general. However, I can't help noticing a curvature at the bottom of the object. I've attached a picture.
I think (and hope) it isn't bad enough to affect the usability of the part. However, I would love get rid of this curved bottom if possible.
From my past experience, I believe the bottom tends to curve up with bigger objects - the object which takes longer time to print.
Is there any way to eliminate or at lease reduce this curving bottom? What's causing this curved bottom? I think the bottom probably curved up actually after the printing was done (as the heated bed cooled down) because.. if these curved got there while the part was still printing, I don't think it would've been knocked down before the completion, no matter how much hair spray used.
Should I set the heated bed temperature higher.. or lower (I had it set at 110C)? Or, anything else I can try?
