Hey, just checking in. How'd this printer turn out? I haven't seen any updates on it and I'm curious how well the 80/20 'bearings' are working for you?

Hi, actually i had too many projects and had to abandon the big 3d printer project. I ended up making my own Lulzbot mini from scratch though and that's where my making my own 3d printer ended. But i did end up using the parts for another project, making a "Food Cube" or PFC Personal Food Computer from that TED talk and the MIT Open Ag forum. (https://forum.openag.media.mit.edu/t/andrews-custom-t-slot-frame-food-cube/1238)

Thank you. Maximum respect. This was just was I was looking for!

For the pads you really want to try something like Taulman Bridge or other nylon.
I have a printed pad that I tested and it slides very nicely on the t-slot I have.

Yes, the bridge nylon works pretty well. The Igus Tribo filament has a lower coefficient of friction though and is designed for low wear.

There is something wrong with the STL for the Andrews-8020 file

I have just uploaded a new export / different version called 8020-6715.STL. Which should have good geometry for 3D printing. As always though please double check by using CURA and the X-ray option to look for red internal walls that will not print correctly. The old file had some red internal walls because of improper exporting from a solidworks Assembly file. This new one should be fine and show as all BLUE with the x-ray function in CURA.

Thanks! I can see the problem. Hopefully i can re-export it and correct the issue soon. Just been very busy lately.

Thank you sir, just saved me loads of money. I designed a printer using these, I'll shoot you a link to it when I'm done finishing the design.

I too would love to see your printer if you ever finished it..

I know it's been a while, but could you post the printer you made with these? Been looking into using T-Slot linear bearings for a large format printer and can't find many examples of printers made with them.

Adrian, though I know you were replying to white wolf and not me since I never finished mine, I can however share the stepper motor mounts I designed for my original printer idea if you are interested. I'm still proud how they turned out dispite me never using them.

Cool! Yeah, I'd be interested when you do. I originally was investigating these as i had originally been designing my own custom 2ft x 2ft 3d printer and/or CNC mill. But that project has never been finished. Still, these have consistently been one of my more popular things uploaded to Thingiverse. So i will be very interested to see what you came up with.

do you know if these will work with V-Slot rails as well?

Well i have never seen nor used v-slot extruded profiles in person before so i couldn't say for sure. And only within the last year became aware of v-slot. I gather that V-slot is becoming common in the maker movement.

But to answer you question, its very possible that these could work with v-slot as t-slot and v-slot are two very similar systems. I can't say for sure that these would work the best in their unmodified form as the v-slot seems to have two 45 degree angle grooves. But whether these work or not unmodified, it also might be possible to modify the teflon/nylon inserts to be a v shape instead of a t-slot in order to work great.

It's an interesting idea. I might even be willing to try to help make some modified files if you'd like to experiment with. It might make for a fun project.

yes works now .....keep up the good work

6517 and pad together look fine its just when you print 6715 then pads there
too long mabey there for the other blocks?

ok, what about now? I think what happened was it was for the 6825 model which is much larger (15 series t-slot). I removed it and replaced it with a new STL file. Let me know. Thanks for reporting the issue!

hmm.... your right...

i'm not sure exactly what went wrong there, but i will try and fix that if i can.. sorry if it caused any inconvenience. First i have to figure out which cad model is off scale...

just tried printing and the Teflon sider dose not fit its to long

oh, really? hmm.. is there any info you can provide so i can try and fix that. The teflon slider is one part i haven't tested printing by itself, but it looked fine in the cad model.

i tried loading a model with no pads and a teflon slider in cura. They look fine to me. They seem to line up fine. Are you sure your using 1" extruded 80/20?
