The response could have been different but it wasnt. So will leave it at that. Feel free to call me if you want, you have my number.
Nope.!! . . .but your talking shite again so it's very tempting.:encouragement::toot:Quote:

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?

Is the "funny" sound you're hearing on ramp down for the pockets, that kind of crunchy gravel sound as the tool gets below a certain point? If so I'd wager that is the tool re-cutting chips which your air is not clearing out of the pocket. I've added a second air nozzle to my machine recently to try and combat some of this, as chips love to lie in the lee of pocket walls and hide from that airstream.Quote:

100% it's re-cutting chips when spiraling down, you need lots more air to blow them out.
Update:
Enclosure nearly done, the design I came up with was really stupid, it weighs loads and took forever. If I was to do it again I would used thicker sheet metal without a frame. Lots more work than I thought. I finally weighed the mill, comes out at about 700kg in total.
I changed the castors on the frame to support the weight and so I could level the frame, spent a lot of time deciding on these. Please ignore terrible welding.

Next step is to put some polycarbonate windows in the sides and then finish painting, doors after...
Your welding is fine... it's your grinding that's awful :-)
Those FootMaster's are brilliant, have three sets holding up three big things (lathe, 2x mill bench and my welding bench). Aim-Tools are a pretty cheap source of them
