K40 focus test file download

When you get the machine, proper focus is inside the spring clamp in the bed. Anything you put on top of the bed will be out of focus. Use the tool you made earlier, in this example i will refer to the tool i have in the download section, i recommend cutting one to use.

Please note, it will only work with the standard K40 laser head without any nozzles attached. Put the tool under the edge of your laser head on the highest step — use scrap pieces below the material until the surface of the material is touching the bottom of the tool.

If you cannot fit the tool — you need to lower your bed. Use the tool i linked to earlier, depending on the thickness of the material you want to cut you need to use proper step on the tool. Ideal for cutting is to place the focal length — If you have 4mm acrylic, you want Use the tool, and set the step with If you cannot fit the tool between the head and material, you need to lower your bed.

There is very common for users to DIY their own movable beds with different solutions, everything from gears and motors to scissor-lifts. I tend to stop users from this, as the focus is very important one millimeter out will have a effect on your final result. Installing a movable bed is a lot of work, you need to make it stable so it wont tilt with load on it — and make sure it keeps level in all positions, in all four corners at all times.

Most scissorlifts are very sloppy and putting anything on the bed in one side will tilt the bed really bad. A ramp test is a angled piece of material on your bed to find your optimal focus. I usually do not recommend this, because the bed in a standard K40 is too far up, the ramp test will not show a proper focus point. If you want to do a ramp test, make sure you lower your bed enough to get the full hourglass shape of your line. Bravo Technologies has made a great video explaining how to do the ramp test.

Hy there! Any idea? Thank your very much! Try the same thing with a piece of wood or thicker paper, lower the power. If you get a smooth engraving on wood, its the stamp material racting and causing the dots, and you might need to play a bit with power and speed to make them go away.

Hi HP First thanks a lot for your website that spared me a lot of headache. I have a K40 mirrors aligned bed right ,focus good …only one problem. Maybe you can help me? Kind regards Razvan.

Inspect mirrors and lens for smudges or damages, you can do a test — Rotate each mirror a halft turn, just turn the clockwise half turn, and see if the spot where it gets blurry moves. If it does, your issue is with the mirrors or lens. To be honest, i have not made much metal engravings at all.

But what i have tested i always needed a marking solution to put on the metal to make it mark properly. Sorry for my limited knowledge here, but i dont think this is a focus or power issue, you probably need the marking solution! Hi HP, I am waiting for the delivery of an Adjustable laser head kit with air assist — 12mm that I bought from your store. My question is how do I install the lens on the Head. With the concave face facing up or down? Rounded side up, flat side down. Put in the lens first, and the oring on top of the lens and tighten it just so the lens is held in place and cannot move, if you over-tighten it you might press the oring so you hit it with the beam.

Is the beam making a donut instead of a dot? Test with a paper directly in front of the laser tube to see if you get the same shape, then move to mirror 2 and before the head to see where the shape is created. If its out of the tube, it can do this on very low power, increase power a bit. When I cut a straight line of 19cm the laser cuts a line of 20cm adds 1cm. Same problem with the Y axis, it add 0.

I understand that this is solved by changing the steps over software and send it to the controller, but I do not know how to do it. Great informations with the widio from techbravo. I hve a std. How is this done — doing severel different effect in same picture????? This may be nit picky, but you mention measuring from the underside of the lens, Since the laser beam starts to bend at the top curved surface I interpreted this to indicate that the Do you agree?

Since the lens is around 2mm thick, that difference could change the distance from the lens, I am particularly interested in this as it relates to my current project of rearranging the optical path a bit.

The thickness is a factor of the lens function. We did some heavy testing on this in a Wyko optical profiler, bad lenses had the shape formed completed a mm above the underside and gave really strange and short hourglass-shapes as the last mm of the lens distorted it. If the deviation is too great, upgrade your lens.
