    Jonathan we have slotted holes on the gantry??
    and as I said "I did the drawing dimensions off the ballnut support as it is fixed in place" but I suppose I lost a 1mm on the pencil line ??

    I now know where I went wrong Jonathan my drawings where based on 20mm material and the material is actually 19.050075 however we do have slotted holes so that should be ok

    That would explain it yes. The only thing that worries me is these errors/tolerances all add up and could ultimately cause the remaining 1mm clearance you will have in the slot, if I make the ballnut mounts 30mm, to disappear. Still it's probably negligible...

    Jonathan make it with the extra 1 mm as we can always mill it off if needed??

    NO It's always nice to see it from the very begining, shows others later how a build is ever changing and just what goes into building a nice machine, which I'm sure yours will turn into.

    Leave it be. . is my vote.!

    It's not a fashion contest it's diary of your build. It's fine and the silly comments just show your excitment, just wait untill the frustrated comments appear then you'll want to delete the whole machine. . Lol
