Same on my printer: extruded plastic holders and 27.0 +/- <0.1mm on both sides. X-sledge runs very smoothly except for a few critical (higher) speeds where it shows some rattling.
Thank
you very much for your measuring the parallelism of the x-rods at
YOUR printers!
Congratulations
to your good printers! I am happy for you!
But I
was suffering from the very beginning by x-offset and rattle, also
with excessive lubrication!.
With
35.4 to the left and 34.0 to the right (Distance from upper top to
bottom of lower x-rods), I had no chance hammering onto the rods on
my so far so good JGaurora5 Printer .
For my
bad luck I got a “sick dog”, but cured now with my ABS-clamps,
pressing the x-rods guides to the left together with brutal 30 N
force for parallelism!

Wayne said: You have no chance, so use it!
But he
was wrong, there is always a chance, but requires a lot of effort.
Would it
make sense if I write a letter to the JGaurora company about my x-rod
non-parallelism experience?
I would
propose a final check at the x-rods before delivering the printer to
the customer.
I do not
expect to get a replacement, since I could solve the problem
respecting the advice of my wife to measure the parallelism. I am not
prood that I did not got this elementary idea earlier by myself!
Dear Peter. I agree with your thinking - if nobody complains, they will not be aware of what to improve. So yes, it probably is good to let them know.
However, what makes me upset, is that JGAurora do not seem to have a consistent attitude of continuous improvement. You may find that they do not care.
Sometimes, it is two steps forward, sometimes three steps forwards. However, at other times, sometimes it is one step backwards. I am curious what possible mistake could have resulted in your poor printer alignment. Injection moulding should be consistent and repeatable.
Dear Sam and Der_Muck Thank you for measuring the parallelism of YOUR printer. I shall write to the manufacturer about my measurement at my “Monday Morning Printer” My left x-axis holder (in front of the X-Stepper motor) is not ok with 43.4 mm outer rod distance. Perhaps the injection molding tool had a temporary problem.
My
JGaurora5 printer operates now perfectly after trimming the two
x-rods to parallelism within +/-0.05mm by my additional ABS-claps .
No
more rattle and x-offset with normal lubrication!
I
suffered a long time at this problem, purchasing replacment axial
ball bearings (still suboptimall like the original), not comparable
with good Swiss bearings, but not available in JGaurora5 dimensions
But
I was „barking below the wrong tree“ as we say in German.. Even
with suboptimal x-bearings a proper operations is possible if the
x-rods are parallel within +/0.1mm!
Dear
Sam
Please
write a Wiki proposal for people, suffering like my about x-Offset
problems! Many Thanks

So yeah, you may have a monday printer @ufodoctor3
There are always intensive brainstormings here
