    Just checking in, good momentum. I actually spent a majority of the day, tweaking all the tiny details…It is much closer than it was yesterday.

    I have no idea how I made the entire thing the first time so fast. This is tortuously slow going. I tried to appease y’all with some no-cable tie solutions, nope sorry. At least not for the X axis, Although I found a slick design that will work as an add on on thingiverse. Getting ahead of myself.

    Maybe I went too far.

    Looks pretty flash.

    Can we get some thickness across the bar that is at the top of this pic to allow drilling and tapping holes for a Y endstop? I’ve done this with my existing, seems to work nicely with a bolt tapped into one of the router carriage bearing holders.

    Also, why the concave surfaces on the bottom-most face of this pic? Looks sexy, but makes for weaker areas where the bolts go through. I’ve broken two of the equivalents in the current design.

    One other thing, I’ve found the spec’d size wheels hard to find, but others that are a few mm bigger much more available. But wheels a bit bigger come close to fouling on the other bolt going through the part mounting the top wheels. Can those two bolts move 3mm further apart?

     

    Also, the little holes for the cable ties mean parts aren’t rotateable. Maybe make the part thicker where necessary and have the user drill a hole if needed. Makes for lower distinctive parts count.

    Hi again!I was just wondering if we can get a list with the parts that are not changed in your updated design,so I can start printing!Just orderered 2 kg of  PETG and cant wait to start printing the parts!

    Thanks!

    I’ve found the spec’d size wheels hard to find

    AFAIK, 60mm (or 59mm) are only used by inline roller hockey goalie skates.

    68mm, 70mm, 72mm are common for all inline roller skates.

    https://www.inlinewarehouse.com/catpage-WHHOCKEY.html?ctype=hockey

    So it makes sense that the smaller wheels are more rare. But they shouldn’t be impossible to find. I don’t know where Ryan found them so cheap, but I bought them from here. Obviously, buying wheels that are great for competitive roller hockey is overkill.

    Much better way to do this would be in CAD, but the carriage does not touch so clamping an endstop on the rail would be best. I have made a mount for this as have a few others.

     

    Also, why the concave surfaces on the bottom-most face of this pic? Looks sexy, but makes for weaker areas where the bolts go through. I’ve broken two of the equivalents in the current design.

    It’s sneaky….it forces more plastic not less. I am controlling strength with external walls not infill that every feels the need to skip on. I have the previous and new parts in hand, the new ones are better, promise.

    That forces everyone to have a 6mm longer table. That also raises up your gantry 3mm, less rigid. The wheels are readily available as Heffe said they are hockey wheels. You can possibly use skate wheels this time around, I have not finalized it yet but I am trying, as they are cheaper.

     

    Also, the little holes for the cable ties mean parts aren’t rotateable. Maybe make the part thicker where necessary and have the user drill a hole if needed. Makes for lower distinctive parts count.

    Whats’s the difference? We are not buying moulds we are celebrating having 3D printers and not saddled with generic multi use parts! The part count on the new build is significantly less to make up for it. If you want to get technically the part count is actually pretty low, most of the parts are just mirrored you could do it with your slicer but it leads to confusion so I provide them already mirrored.

     

    update……I hope to start build the test machine today or tomorrow!!!

    WHOA… Pretty slick. Only the top two wheels on this version? Do you think the bottoms are just not needed then? It does seem to have a good amount of support with the tops, and I’ve noticed some people don’t raise theirs to table level anyways.

     

    Loving the design change. I guess I know what I’m building myself for Christmas!

    Looks good. I really like this. I like how the leadscrew nut mounts. Is there any way I can get the garage to look like your renderings?

    Not until I try it.  🙂  It might fail miserably. And i need to work out hose routing still.

    I don’t take it that way. Makes it easier to understand what you’re on about.

    I broke a few of those parts, having spares printed already made things a bit easier. But I understand your rationale, makes all the sense.

    BTW, I can beta test the new gantry pieces you have the pic of above tonight if you’d like. I have to print some of the broken bits anyway, why not print the new ones, then break them? (I’m assuming, but for no good reason, the tube spacing is the same and the motor mount would line things up.)

    These bits:

    Well this is probably going to ruffle a few feathers but every piece has been changed. Some by not very much…Sorry. I did try and first to make a swap-able system but it just gets too constrictive and the build ends up being even more similar than it already is.

    Trying to get the day to day stuff done so I can try and get started on finalizing this. I want to run through and double check screw lengths and try to get them all the same 1″ or 1.25″ (25-30mm) whatever works out the best. That gives more meat so maybe you gorillas will stop splitting parts (shhhhh I do it too)!

    As soon I I verify the no bottom wheels thing is okay I will upload the parts, under the condition that everything might change. once it gets proven out I will fix any small issues and work on instructions. Nothing new here as this is my usual approach but just in case you were unsure of my timeline.

    Somewhere in there I buy bulk hardware and will be making Jigs. I already have a large batch of the stuff that gets imported (10mm gt2 stuff) so I should have 50 or so worth ready to go when/if it is ready.

    I should be able to make a 25mm version pretty quickly and after that I can possibly adapt it to 6mm gt2 again but I doubt that will be worth the effort / cost difference.

    Nice design, I especially like this big middle bracket, it looks great!

    Just one little concern, if I may: The bracket on which the leadscrew is attached seems a little weak to me. Considering the fact that this little thing will have to support the entire weight of the gantry+router+vacuum attachments, I’d be worried it might break or at least flex quite a bit.

    You might want to beef it up, which shouldn’t be very difficult.

    Just my 2 cents.

    Looks like it prints in the orientation it sits in the assembly.  Would be pretty hard to shear off since there’s very little lever action with it as close as it is to the edge.  Looks to be about the same size as the current lowrider part, just less mass out from the attachment point.

    Yup, it is a big unknown for me as well. I have to test it. It is 8mm thick, but the screw points are much more of a concern to me than the actual overhang. If it sucks, going back to the other style is easy.

    I left a bit more room around the T8 nut so if you leave the T8 screws 1/4 loose it can actually move a bit for less friction / better out of alignment tolerances.

    A choice has to be made. Maximum table thickness.

    My thought process. Over kill to me would be a torsion box 2×4 table with 1/2″ skins on both sides. That is under 4.5″ thickness. I think a more realistic table is 2×4 Or 1×3 with a 1/2″ top skin or 1/4″ top and bottom. That is 4″ thickness.

    I know it isn’t a huge difference but it does make a difference. I am siding with the 4″ unless someone has a valid reason to go thicker.

    I believe I’m overlooking something.  I thought the only reason for a max thickness was the fact that there were wheels on the top and bottom.  With no wheels on the bottom, why does thickness matter?  I’m going to feel stupid when you point out something obvious, but, hey.  ¯\_(ツ)_/¯

    #62971

    Easy overlooked, I thought that way at first as well. The lower mounts still hang under the table a bit. No easy way to make that go away. Anything that hangs past the tangent edge of the Z rail is under (or on top) of the table.

    Some room was saved not using the wheels (1″) already but I went a tad further. I am going to try and make an easier table, a little lighter as well.
