Epoxy granite vertical mill build log

[Nick]

Thank you both for the advice. I have had a lot more success. I bought an array of end mills from shop apt. I have also been using single flute end mills that I saw used on a Datron machine, these seem to work quite well, there is a bit of chatter and they make funny sounds on ramping. I've even tried filming this.

I have noticed that my setup isn't as rigid as I thought, there is nearly negligible backlash if I move the table with no force but if I apply some force to the table I can move it about 0.05mm in x and y direction, I can get it to almost 0.1 if I really lean. I'm not sure where this is coming from, I think it might be the ballscrews / x-axis belt, i'm not sure how to isolate this? I know a lot of people were having issues with the ball screw BK12 mount bearings.

I have ordered some metal for the enclosure, I was going to try and bend sheet metal, but I've abandoned this idea and I am going to weld a frame and then bolt/weld sheet metal onto it. Not sure what to do about the doors yet, any ideas?
