    Am I looking for trouble by putting the vacuum under the back of the machine?

    The controller will be at the front which is a good 4 feet away.

    That's a pretty impressive cabinet you have drawn there. :thumbsup:
    As you haven't mentioned noise, although it would help some, I assume it is solely for containing dust.
    If, however, you have a good extraction system, and you are not going to be using it in your lounge, I don't know that you need to go to all that trouble. :rolleyes:
    I've used my old machine with a shop vac sitting right next to it, and had no problem, other than having to earth the vacuum pipe for static. :)
    You will need to consider how you will
    get the pipe from the vac to above the machine. Perhaps the table would need to be longer at the back so the pipe can rise up through the table and make its way to the Router/Spindle from there.
    As a thought, I would put a great table like that, on adjustable wheels, so making it easy to move and make all areas around it accessible.
    In fact I think I might use a few ideas from your drawing for my next CNC table. :D
    Good job.

    Hey GrayUK,

    Glad to meet you and thank you. Seems we have the same thoughts.

    I have a few possible reasons for the enclosure.

    1 - Dust, though the dust collection might be enough
    2 - The machine will reside in a dirty environment. Though a tarp thrown over it while not in use will work.
    3 - Noise. I didnt buy a router with it. I have a dewalt that I will try out first, though I might end up with a spindle. From what I read, due to the length of the X axis, weight of a spindle is a concern, but I havent really done too much research on that yet.

    For the dust collection part, I already have the pipe coming up through the table top. You just couldnt see it in the picture. Heres one showing it better.

    The reason for wanting the dust collection under the table was to hopefully cut down on vacuum noise and (to your other point) make the whole thing mobile. For the noise part, I ended up buying a Fein Turbo I. Its only 66 db and works great. The floor of the dust collection cabinet will be perforated and the sides will have a few fans. This should help with the heat generated by the vacuum. (The cabinet has doors, but I didnt show them in the pics)

    For the mobile part, I have castors, they just arent modeled. I bought these removable ones from Rockler

    I did consider picking up Rockler's anti static hose, but decided I could ground the hose that comes with the vacuum. Just another bit to sort out later.

    For ease, I did buy the xPro with the bundle, but may go a different route down the road. I searched for the bluetooth adapter yesterday, but it seems everyone is out of stock. That got me down the path of moving the xPro to the front of the table which I think is a better option anyways. I still havent decided which way I'm going to go with the control panel. I built a custom one for my Tormach mill and I'm leaning that way with this machine. Again, its a decision that I'll make down the road. I really just want to get it hooked up and some hours on it so I can see where I will be standing and what areas I need access to regularly.

    Hi Shawn, yes that looks like a great cabinet, so congratulations on thinking ahead because dust collection can be an issue. Like GrayUK I haven't done much yet regarding dust, so I will be keen to see how you go. I've built a c-beam XL with extra Z height, but when I get time I should do something about dust collection.Images

    Thank you, Geoff. I think I'll be doing something about Z height down the road as well. Unlike the ozznest workbee, the openbuilds one doesnt have two spoilboard positions. As ordered, there's only 1.5" clearance. I think that's going to annoy me quickly. LOL, I took a look at your pics. Great stuff!

    Yes I think you can gain alot by increasing the z, it's easy on the XL, I increased the gantry support length by 4", and to be honest I have never noticed any loss of rigidity, I guess there is, but I'm only cutting wood, and it's not a problem. I guess you will have to cut new plates for the Workbee, unless someone has already done it. Ryan from Ooznest would be my first call if you decide to do it. Anyway good luck with your build.

    Took a look at your projects. You've made some pretty cool stuff there. Really impressive. :thumbsup::thumbsup::thumbsup:
    I like your simple solution to deal with the sawdust for now. A case of K.I.S.S. there I think. :D
    I plan to have my vac at one end of the workshop, away from civilization, then run a pipe to above it, and then drop down onto the machine.
    Just as well that the suck you start with, will be the suck you get at the other end. :rolleyes:

    Impressive cabinet. This should really help reduce noise.

    Thanks GrayUK, now I'm an aging present maker for friends and family, but it keeps me out of the pub. Yes it's a simple half solution but means I can sweep or vacuum out when necessary. I must try harder one day!

    I'm working on adding the X assembly to the 250mm C-beam. I adjusted the eccentrics so the wheels are touching and moving the c-beam when turning the wheels. However, the center wheel on the opposite side of the eccentrics isnt touching (therefore not moving). In the build video, it sounds like all three eccentrics should be adjusted the same amount. In order to get the middle/non-eccentric wheel to turn when sliding the c-beam, I need to adjust the center eccentric to the point that the entire assembly has too much friction. For reference, the outer two eccentrics were turned to the right less than a 1/4 turn. To get the center non-eccentric wheel to turn, I need to adjust the center eccentric 1/2 a turn.

    I found the following in the Ooznest version instructions.

    "Initially, the CBeam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the row of wheels with the Aluminium-Spacer-6mms. Starting with an outside pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam WorkBee CNC Assembly 17 Extrusion until there is a small amount of friction between both wheels and the CBeam Extrusion. When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion."
