Some small progress
Last days I have been working on the gantry
As I said even if the gantry has be milled in a six meters planer, there were some small errors that could be corrected with a couple of aluminum foil.
I don’t know if everybody who had some part milled or use the epoxy method has a true flat surface or i am the only one
Even if the error wasn’t so big, i decided to be as accurate as i can with the means that i have (a 1200mm straight edge) and make the rail as flat as possible. I decide to use aluminum foil shims. i have one basic principle in my construction. As this is my first build i want to make secure steps with so that it won’t be needed to come back again. I think that every small error become large as the progress is going on. That is why I use shims even if i had the gantry milled. To be honest the most useful work after having the gantry milled, wasn’t the leveling process but the milling and taping process.


The planer mill 3mm so that there is a datum face for the master rail


The other rail will be adjusted for paralelsim by following the master

I put the rails temporary to get an idea about how it will look like



After shimming the master rail i tighten it to the datum face

Some pictures from the z axis that follows

Tommorrow i will start adjusting the slave rail according the master
