Spoiler board surface accuracy

Hay All

I received my pro beginning of Feb and I have built and followed all of the tramming guides (which were super helpful) and now have a spoil board installed and surfaced.
I don’t have any ridges and the surface is very smooth.

At the end of this process I measured the level of the spoil board to the router across the cutting surface.

I have a difference front to back of 0.013"
left to right is 0.008"

center is 0 point

My question is what should I expect this to be ?
I’m only cutting wood (no aluminium) so will probably be ok for my needs , but the engineer in me wants to get this as low as possible :slight_smile:

MDF is pretty reactive. Some of that could just be humidity getting into the newly exposed MDF.

I just remembered that I once posted about my test with the Mini Pro tram, and back then I got 0.004" front to back. But that was measured on an aluminium bed, not MDF, and as @mhotchin noted, MDF does its own thing sometimes. Something you can do is use a piece of glass on the wasteboard, and re-measure, see if the value is still the same?

Anyway I wouldn’t obsess about the value if you get nice clean surfaces at the bottom of milled pockets.
