Re: Finished rebuild of my K40 laser cutter

The blue plate is acrylic cut on the laser that I knocked up in Fusion 360. The box that the micro switch is in I drew up in Fusion and 3D printed and yes you need two limit switches for the z axis. Again I just 3D printed the bracket or you can laser cut from the design that is on this site. Hope t...

Re: Finished rebuild of my K40 laser cutter

They are the same diameter at 50mm so no adjustment was necessary.

Re: How does XLE XY Stage mount to frame?

I just used the same bolts that came with my extrusion kit which where m6 x 12mm.

Re: How does XLE XY Stage mount to frame?

There are holes in the bottom of each end of the square tube and you mount it to the extrusions using the normal bolt and square nut.

Hope that helps

600x400 aluminum kit question

I have got 6 shorter pieces of extrusions left labelled "cover", but I cannot figure out what they are meant for and they are not shown on the instruction.

Can anyone let me know what they are for?

Thanks

Homing Switch Position

I am in the process of building my LO 600x400 frame kit and XLE XY stage and I was wondering why the mounting holes on the xy stage for the x axis where on the back right rather than the back left like the y axis home switch. Before I move the x axis home switch to the back left, I just wanted to ch...

Motorized power Z table for 600x400 aluminum frame kit

Is there any information or pictures of how to mount the Z-table in the LO 600x400 aluminum frame kit? Do I omit parts "e" and "k" of the frame kit, maybe mount parts "e" to parts "d" on the second horizontal level up from the bottom then mount the z-table to ...

I have my kit on the way and have redrawn the constructed kit in Fusion 360 so I can use it as a basis for the rest of the build. Based on the LO setup diagram, there seems to be a discrepancy in one of the dimensions as follows: 1. Assuming on the second horizontal level from the bottom that the di...

Re: Finished rebuild of my K40 laser cutter

Thanks.

The z-table would fit anyway (I also cut about 1" off the exhaust extractor outlet), but yes I used the LO head with the air assist and changed the mirrors and lens.

LO LPSU 5v output

What is the 5v output for on the LO laser power supply for? Can I use it to power a LED laser pointer for aiming?

Thanks

Re: Laser burnt a hole in the mirror

Thanks Marco,

I already upgraded the lens and the mirror in the LO laser head to a 20mm Si mirror and an improved 18mm ZnSe 50.8mm focus lens which I assume should be fine for the tube.

Thanks

David
