Retesting the x axis gave me the following figures that I'm pretty

4.01 4
5.04 5
6.03 6
8.06 8
10.05 10

I cut some test holes, a rectangular cutout and some circular cutouts.
Both were within 0.05mm (~2 thou?).

I changed the cutting bit to a 2 flute 1/8" dremel router bit and got a
much
much cleaner cut with little to no melting of the plastic and little
burr
left on the edge.

Some pics here of rectangular cutout & circular cutouts:

Thanks for you help, you can be assured there will be more questions to
come!



What did you find to be the major source of error, or did you just
take the shotgun approach?


LOL. I usually do both. Try to find the major problem, and as long as I
am adjusting I adjust everything.




Shotgun approach - tightened & centred everything I could think of.

I still need to square everything up some more. Typical runout seems to be
about 0.15mm per 100mm travel on the table - probably not a major issue for
routing work.
