    Hi

    Thanks for a great design.

    We have printed all the parts for the international version and started up with the assembly.

    It seems that the IE_Middle_Joiner_25 and the IE_Middle_End_25 does not fit the 25mm conduit.
    I think it still fit the 23.5mm.

    Could You please check up on the files?

    We have tried to loosen all bolts but the conduit will still not fit.

    Thanks

    Hi Madskjaergaard,

    What is the exact OD of the steel tube that you are using?

    Cheers

    Hi Greg

    The exact OD is 25.04mm

    I have tried to remove the middle_joiner from the rest and loosen the bolts very much.
    Now it is possible to force the tube in place but it is not running as smooth as it should.

    Hi Mads,

    Just done some dissecting of the IE_Middle_Joiner_25 file and found that the tube diameter should be 23.87mm.

    You can view the screen shot here :- http://screencast.com/t/64LTVJjiwr

    I’m using Sketchup Pro, and I know it is very accurate.

    I have only printed the four corner blocks, but now I think I need to check all of the files in the International folder to ensure that they are for the 25.00mm OD tubing!

    Cheers
    Greg.

    I take these things very seriously, I have been wrong on a part and found out about it in the forums.

    I spent the last 40 minutes double checking all the middle parts. The ones on thingiverse are correct. The dimensions you gave do not match either the international or standard piece. I do truly appreciate your looking into this. Could I ask you to double check that with a fresh download. I could still be wrong but I regenerated a middle joiner and compared it to the one online and they are identical. The number you should be getting is 24.8mm. Taking dimensions off STL’s is not very precise but your number was so far off it made me go back and check. I’m not sure how you are locating the center of a “hole” on an STL since they aren’t round, I suspect that is the problem. Meaning the bolt holes for the bearings.

    I would prefer a private message to take care of things like this to make sure misinformation is not being spread needlessly. I have no problem being wrong publicly, but in case I am not wrong I do not want to discourage people from building this because of a post like this.

    I have double checked that I have printed the correct part.
    You mentioned in another post that the thin wall should be around 3mm – mine is 3.3mm

    I will try to drill a little bit off the holes to give a little more room for the steel tube.

    Vicious1 – is there any other measurements I need to give a check?

    Vicious1, I’m happy for you to remove my post. If people ask why the post was removed,
    they know it was because I request you to do it!
    I fully understand that misinformation can lead to people asking the wrong questions.

    I also state here that I may have not dissected the part correctly, therefore my posting
    may not have been 100% correct!

    I will PM you all my future findings, from here in! Unless I feel my information can assist
    other with their build!

    Cheers
    Greg.

    You are right, something is wrong. Thank you for bring it to my attention. Sorry for doubting you.

    I doubled checked my sketch and the dimensions are correct, double checked that the holes moved and they did. I didn’t take it any further until I got your emails.

    My master sketch has the right dimensions, the holes have moved, but not enough.

    I need to figure out how this even happened. I also need to fix all the center pieces because that one center hole drives all the dimensions. I will take them off Thingiverse for now until I can sort this out. It could take up to a week, I am moving in 2 days so I need to pack before I can fix this. I am wondering if I screwed these up when I made the new rigid center part. it is a complicated part.

    Again Sorry for doubting you, you are correct the parts are not right.

    Thank you guys for figuring this out. Asho777, thanks for making me see the errors…I’m an ass.

    I am uploading the new parts now.

    This is how I see all forums :- You EITHER, have people that winge (whinge) and complain, along with moderators that think they are always right and could never be wrong, so a useless waste of time arguments, in postings will continue! OR, you have this Vicious Forum, where people love the product, are being fully involved with building the product, and put forward valuable information, to help others. The most important thing, and the reason I do like this forum, is that the owner, Vicious1 can announce publically that he is only human. This was proved to me by the fact that he went and checked again and found a small error. Then he push every other thing, including packing for his move, aside, to rectify his small mistake, and update all drawings. I say good on you Vicious1, my hat comes off to you sir, and keep up the great work!

    Now lets get back to building and producing end products with this baby!

    Cheers

    Hi jitendra,

    I’m currently printing the IE International version, but this version is for the 25.0mm OD, not the 23.50mm OD.

    Cheers

    Nope 23.5 is the standard.

    It won’t take long for the forums to get junked up with the UN-friendly’s.

    hi vicious
    i want to order the bundle part but it has only 13feet of belt and i want to make 48×36″ size machine . can u increase the qty as per this size.

    #3182

    Ryan
    Keymaster

    You can add as much belt as you want in 6.5 feet increments in the store. That is a very large machine do you have some experience with these kinds of machines? That is much larger than recommended, but it depends on what you’ll be using it for really.

    is this site showing the US dollar .
    any idea how much to pay for custom clearence.

    As you had indicated that all parts printed by you were for the International CNC Machine. I know that you require the 25.0mm OD Steel Tube!

    I don’t deal with customs that is all a local thing on your end, I have no idea how to look that up other than googling it. I have never had to pay a customs fee.

    You might want to use the contact me link in the header for these kinds of questions. This is the assembly forum.

    BTW, what is the largest feasible size that the CNC router could be made to take? I just want to cut and mill 3mm Styrene sheets.

    hi greg ,

    you was right 23.5 mm od conduit is loose in the parts. i think its for 25 mm .now i have to buy new 25mm tubes.

    Oh wow, I thought I was just useless but I feel better now.

    I printed the Middle parts myself, didn’t fit the 25mm conduit, ended up drilling the bearing holes out so much that the parts weren’t accurate anymore. Figured it was my 3d Printer, paid $85 to reprint on 3dHubs, SAME PROBLEM.

    Luckily I am now friends with my local 3dHubs member, hopefully he will reprint again on the cheap.

    I have a question though, I am using the Rigid Z, when I force the 25mm Z tubes into the Rigid Z it’s so tight it forces my X and Y axis to go out of square (so much so that you can see it with the naked eye!). When I remove the Z tubes you can actually watch the X and Y axis snap back into square! I have drilled all the bearings holes on the rigid Z out so far that I am afraid to go any further as I fear the parts will be ruined and still I can’t stop it forcing my X and Y out of square.

    Has anyone checked the Z parts to see if the dimensions are correct? Cause I’m pretty sure they aren’t.

    EDIT: Yes I am sure they are IE_ parts (I have a 3dHubs screenshot to prove it), yes I am sure my pipe is 25mm (I’ve bought 25mm Aluminium tube after I suspected the electrical Conduit was causing the problem, the aluminium measures almost dead on 25mm on my calipers).

    Check the diameter in your software for the 3D models themselves, if it is correct, it is possible that if you are printing with ABS that you are getting too much shrinkage.

    The only thing that I can think of is that you downloaded the Z middle parts before they were updated.

    But as you can see this was rectified very quickly by vicious1. so if you downloaded these parts before the 22nd September you will need to download them again.

    The only other thing is that you may have printed the other version not the IE version!

    All my prints are in ABS, and the Z section all fits very good.

    Cheers
    Greg.

    Hi Laserman,
    I have no idea how to check the diameter in a STL file?

    Both sets of parts were PLA.

    Hi Greg,
    Yep I downloaded well before that date, I printed them months ago, I was looking to confirm if the Z axis dimensions were wrong too?

    Not the Middle_joiner parts but the rigid Z where the two Z axis tubes go through.

    As mentioned in my edit, these are all IE_ parts (I have proof if you need it). I printed them in PLA (twice).

    Cheers,
    Joe

    No, if you say they are IE parts, that is fine.

    I actually checked all the Z axis parts before I printed them, and they are spot on to dimension, but after that date!

    So if you downloaded them before that date and printed them months ago, that is your problem! You would need to download
    the newer version of all those Z axis IE version of parts.

    Vicious1, I’m sure will chime in here, but I thought the new rigid Z parts were in fact all good.

    Joe, if you like I can check the the actual parts that you have printed and get back to you with the actual dimension for the tube that fits through. As the STL file that you currently have are all the older ones, you would need to get them to me. I would not suggest you post them up here, only because, if they are incorrect we don’t want others to download them and use them.

    This brings to light a request to Vicious1. Can you setup in the forum’s admin area the ability to PM (personal message) others within the forums. That way if others need to send certain information to other people on the forums, it does not have to be in a public forum, for all eyes to see!

    Cheers
    Greg.
