very nice any version for 2060 extrusion

Hi,

The X-Axis uses 20x60. But i am not aware of any version which use 20x60 on the X-Axis, it currently uses 20x80.

Be very wary if purchasing anything from Ooznest. They DO NOT warranty any of their products!

What is the thickness of the plates?

1/8" and 3/16" will also work fine

Hi,

Most are 6mm, a few are 3mm.

Is this machine at the end that speed got at work?
From 1 to 10. What number do you get from working speed?

Hi,

Sorry i don't understand the question?

Best Regards

I'm researching a CNC build and this project looks right up my alley! Logically, the v-slot aluminium extrusions should add more rigidity than stainless tube which is fantastic for larger build surfaces. What do you think the maximum build size would be for this?

Hi,

For this design the maximum size if 1500x1500mm.

Any longer and you get problems with belt stretch, and the rails wobbling along their lengths.

You could do the double belt mod, and support the Y-Axis extrusion along its length to help with these issues if you went bigger

Thanks for your response Ryan. 1500x1500 is perfect! I noticed that you need aluminium parts for this? Is there any way I could print the required plates etc in ABS temporarily, then mill my own plates once the build is finished and swap the ABS for aluminium? Do you know where the STL files are to print?

Hi,

Someone has 3D Printed them before, see here: http://www.openbuilds.com/threads/ooznest-ox-with-3d-printed-gantry-plates.8567/

There is a zip file in this thing with all the designs for the plates, you could probably make the STLS needed from them.

Ryan

I hope you don't mind, but I took the liberty of creating a remix (https://www.thingiverse.com/thing:2338744). All I did was take the advice from the guy who built this with ABS and extruded all the drawings to 8mm thick parts (he recommended 6mm). I just thought I'd help out in case anyone's interested in printing and building this and don't have access to a CNC or the money to a mill these. Worst case scenario is that they can build it in ABS and mill the parts when they finish :)

Hi,

Nope that is fine with us :)

Ryan

I'm just running through the installation guide and I can't seem to find the DXF for X-PLATE-FRONT and what looks to be a spacer (see link with red arrows pointing to the parts). Am I missing something?

Hi,

Yes, that is a standard part, you can download models for all them parts here: http://openbuilds.org/projectresources/step-parts-library.162/

Best Regards

I think I figured out the problem. In your design files, you've got files labelled as z-plate-front and z-plate-back, but in the installation guide, they're labelled as x-plates.

Yes, sorry we changed it when we came to do the manuals i think.

Ryan

Fantastic! Thanks for sharing the link Ryan :) Maybe you could post the link in your description so others looking to build this using 3D printed parts can easily find it and tether into your wonderful project here.

Just spotted something on the amazing full res images you have uploaded for your OX as a possible safety improvement:

I too use XT60 connectors for my custom 3D printer from the power source to the controller (the high amp lines) but I liked a comment from some random forum (can't recall now!) to have the female side in the PSU to reduce the chance of shorts. Especially with a CNC machine which may be spitting metal shavings around, with the male "prongs" visible there is a chance that the metal shaving could short this connection? (I am looking at image 8 of the PSU sat behind the OX)

If you use the female side the gold contacts are recessed into the plastic surround and more unlikely to 'catch' metal shaving and short out. The same principal and reasoning are applied to IEC plug cables etc where the live terminals are hidden within the plastic to stop shorts (or people licking them!) and plug into male prongs which are not live until plugged into the cable.

Just a suggestion as a design/safety upgrade perhaps?

I need to get myself an OX, they look amazing, and your builds are great!! Keep up the good work guys!

Steve

Yep, coming from a lot of FPV building, the XT60's are indeed around the wrong way. The female XT60's should be located on the 'live' end :)

Hi,

Many thanks for the suggestion and we did think about this. In the image you mentioned you can see 3 outputs, only 2 are needed to run the machine, so they are permanently plugged into.

The third one isn't needed, in the manual we recommend that if customers don't plan on using that extra output leave it disconnected.

Thanks for the kind words!

Best Regards

Ryan Lock

Yeah that sounds good. So if you licked that spare XT60 there wouldn't be a live load on it?!! More of a tingle than a 9V battery!! :-)

Maybe a future upgrade on the PSU cover design is to suggest flipping these connectors round - safety by design and all that? That would allow all connectors to be connected and live, but pose no risk of short.

All the best - keep up the good work!

Steve

Hi,

Yep, we will probably change it round, would be a very simple change to make.

Best Regards
