ARG. I bought the wrong wheels. I bought the hard wheels instead of the V-wheels. Any reason why you used one over the other?

Having built one of these, I don't think you'll have a problem with either wheel. I wasn't a fan of the 3d printed carriages and switched to openbuilds plates.

missing x stage + focus carrier in package

X stage is the "Y stage X stage carrier", print an extra one for the focus carry. Otherwise i'll try to dig through the old files and see if it's still around somewhere.

The whole laser will perhaps be updated with new instructions as soon as i upgrade the controller.

also, is the main laser carriage the same as the y axis?

Comments deleted.

nm, i see on thingiverse that it is different, but it has not been uploaded here. thinking about using http://www.thingiverse.com/thing:670990 for anyone in the same situation

Buildlog 2.X Laser X Carriage Plate for OpenBuilds V-Slot Extrusion Extrusion ( with J-Head Mount )

this part didn't really work, was made for wider extrusion it looks like.

I decided to print another x-y carriage and put a piece of extrusion in it. from there, i drilled the appropriate holes in a piece of aluminum angle and boom- now i have an adjustable height carriage

I was wondering if you could post a few high res pics of the various mechanisms and assemblies?

I have a 40W chinese laser that I have upgraded to a DSP unit. I may have to print this up and give it a go. Larger cut area and room for a TRUE 40W laser tube.


I don't have a space in the workshop for one of these just yet, but when I do build one it will diffinately be based upon this design and your components. I can appreciate that you understand how to effectively utilize a 3D printer to make the complex components in an assembly and use premanufactured combonents everywhere else. Too often I see people printing things that would have bee easier to manufacture in other ways, not to mention faster. I Say build tools that make you a better builder and then focus on being creative. Its all about throughput.
