    The way you have it will need much more protection for the screws, both lower and upper. Just remember chips go up then back down again so they will settel on the top rail and screw.

    I'd also urge you to cover the Z axis, to be honest I do this on all my machines now as it keeps a lot of crap out the works, but it's Esp important on vertical machine either way up as the dust settles either on the backside or onto rails etc.

    Which way is best.? . . . .Well let me just say my new machine is going on wall when get chance and it will be other way to what you have.!!

    Where did you get those markers.?
    Ok I'm sold, if both you and Clive say it's better the other way ill put it back how I was originally going to have it!!

    I am going to make a cover for the Z axis (just not shown it here) and the back of the Y axis will be covered with an Ali or perspex plate and chip deflectors put on to protect Y axis rails. The X axis belt will be covered. I'll be putting sides on the machine from the X axis rails down to the bed and also at the back to stop chips from flying too far round the enclosure.

    I got the markers from Worcester Electrical (WED), not the cheapest I'm sure...

    Running out of mechanical things to do now so suppose I'd best stop fannying around and do the electronics.....

    Only thing better is chip control other than that there's very little difference, If want to be Knit picky then could say your original way will give slightly faster rapids but in practise this doesn't matter as it will be more than fast enough.
    One thing I will advise is building in some Bump stops at the bottom and when not using for extended periods Park it onto the bumps. This takes strain off the ballnuts and bearings.
    I use Gerry's 2010 Screen set which as a PARK position so used this to lightly bump upto stops when finished at end of each day. In use I used the TC(tool change) option to send Gantry to top of machine for loading material tools etc.

    You won't regret going vertical. To fully appreciate the difference use the machine in traditional Horizontal position before going vertical.!! . . . Before I retired my old machine it was horizontal for few agonising and messy months. It's replacement as been working for only a few weeks and already the chips flying around shop are driving me crazy, and that's not to mention the room it's taking up.!!

    I've got some hard stops at the bottom end and will be putting some rubber for the gantry to rest against as you suggested this when I first mentioned going vertical. I'll use it horizontally until I've built the frame but it'll have to be on the floor as the tables aren't strong enough to not be shaken to bits with it on running at full chat....

    Slight bit of damage where it looks like it was dropped, nothing serious just cosmetic and nothing that can't be sorted with a file! Spindle spins freely and smoothly...

    Started the PSU this afternoon, got to fix the rectifier (need some thermal paste yet) and then decide how I'm going to do the fuses...

    Ok so done the PSU. One thing I'm not certain on is the rectifier wiring. Can you electrically minded people have a look and make sure I've got the connections correct, I think I have but would like confirmation...Thanks!

    I would not be happy with the choc block you need some sort of insulation under it as any stray wires could short to the chassis. Also a larger choc bloc might be better as you are daisy chaining the power from one to another. It would be nice to have a separate wire to each from the main. Just my two cents worth. ..Clive

    At first glance I thought that, but he's using such excessively thick wire that it's probably not a big deal.

    I tinned the wires (and soldered them together) daisy chaining the power in the choc block which is 15A rated so I thought was big enough? I'll put some form of insulation under it if you think it's needed? How would you do a seperate wire to each from the main?
