Cetus3D 3D Printer
Joules:
Do your previous prints measure identical ? Unless you have a draught blowing on one side of the printer, cooling should be pretty consistent. It can still contribute, but you would see it in X,Y error.
Think of a sine wave with a straight line average. Your tolerance has varied over different size in different location. Depends how much you want to chase the tolerance. My experience in what you see is a very slight eccentricity in one or more of the pulleys. Maybe an over tightened grub screw etc.
The sides will exhibit distortion, bulge or hollow if they cool differently, it wouldn't remain square.
Joules:
Keep in perspective, 0.1mm difference I would ignore, you are only 50 micron !!! over. Not bad out of the box if this is representative for this machine. I do hope they get imported into the UK by someone.
Forgot early on to ask what are all the peg dimensions in X,Y The same ?
awemawson:
Pegs measure as follows for the five samples:
(Peg #, X, Y)
1, 6.18, 6.17
2, 6.15, 6.20
3, 6.21, 6.20
4, 6.21, 6.17
5, 6.23, 6.19
(No record of which way round they were printed, so ascribing X & Y is random)
So I reckon that's pretty consistent, and certainly good enough for stuff I'm likely to be making
Joules:
Nice one Andrew, and your worst case is 50 micron. :thumbup:

Can you print gasket? Something more rigid body and then some elastic/inert material? Or elastic seals to cardboard former?
