Hi.
Getting together all of the bits. What size V-Slot wheels do you use for the gantry etc. Are they the 24mm diameter or the 15.23mm diameter

Many thanks
Dave

I use mini v wheel

I really love this for its simplicity.
Re the motors do you use 2 for the Y or one

I used 2 but it can certainly use 1

The SVG I downloaded was broken apart and the DXF was on the side didn't have adobe to lay it flat trying to use the SVG are the mirror mounts in the DXF file?

I see the DXF file is on one of the side planes not the TOP plane I couldn't move it in Lightburn (laser cutting software) because it treats as 2D any way you can upload it with the DXF on the top Plane?

Updated, thanks for the heads up, I presume most people just opened it on a 3D modeling software and rotated there.

Awesome! I did get it flipped and printed. Thanks for the next guy ;)

After doing some calculations i'm not sure the recommended 1m is enough for extrusion. 1m = 3.2ft and my machine is 2.5ft across so I think 2m is more reasonable amount to order. Just if anyone is looking to order.

I've gone through everything I can find on this - but at no point can i find just how large you actually made the cutting/engraving area.
So what is it :-)

its about 250mm x 550mm if im not mistaken. You could just actually measure it based on the parts and also consider not every k40 has the same internal size. Hope this helps

thanks !
Have you made an adjustable height bed also ?

Nope I haven't, but there are some many out there.

Thank you very much for the info and for the design. The documentation and time spent on this project is greatly appreciated.

Just love your idea! Are you using smoothyboard or another controllercard?
Best regards
Jeppe :)

Thanks. At the moment I'm using a smoothieboard. If you want something easy to upgrade made specifically for the K40 get one board from cohesion3d.com

Thanks! I ordered it right away :)
Now i just has to source the alu-profiles here i Denmark.
Best regards
Jeppe

Hey Iove the idea of upgrading a k40 laser to a bigger build platform.
So far i have not found the exact Measurements of the different aluminum parts (cut to length).
Maybe you could help me there, it would be the best to get them in metric measurements.
Keep on doing youre work :).

Glad you like it.

There are various reason i did not provide exact measurements for this: Deflection of the case and k40 model differences.

Just to give an idea my lateral rails are 360mm. The middle one you'll need to measure after cutting all the rest and finding exactly the length you need.

hope this helps

This is awesome. Thanks for sharing the design.

Glad you like it, hope you find it useful. If you have any questions let me know

si possono usare v openbuilds IN POM 24 MM ( 24x10.2) invece delle Delrin Mini V?

You can use whatever wheel that's the same size as the mini wheel

OK thank you.
then I'll have to change the design if I can see that I already have 24mm wheels.
how come the attached drawings are not seen correctly?
