Re: having touble with print (any suggestions)

that is not an easy print to do.

looks to me like it tried to print them, but maybe broke them out as it built up?

slowing things down may help a little.

Re: having touble with print (any suggestions)

I agree with Heartless. If you look you can actually see part of the missing number merged with the next number. You might want to slow it down, or raise your print temp 5 degrees to get better layer adhesion. also make sure your alignments and heights in your mechanical structure is all good and the print head is not dragging on previously printed areas.

The X2 is a dual head if I remember right. You do not want both heads at the exact same height. Which ever head is your primary should be left where it is but the secondary head should be raised so it is about .02 to .05mm higher than the primary. If it is not done this way the secondary head will drag across previously printed layers and could knock them loose or worse knock the entire model loose.

Printing since 2009 and still love it!

also use ABS, as PLA stays soft too long. and if slicing with Slic3r check the avoid crossing perimeters option so it dont drag over stuff as much and set a Z lift number. these add print time but save failed prints better

I slowed the speed down to about 40mm/s and here is how it came out.
