I was looking into purchasing a MR20 laser module and would like to know what the focus distance is (from the material) as well as the laser tolerance? (the R30v2 gets faded a mm out of focus)
Also, if you have a PDF manual that would be awesome to see!
I’ve searched for it a few times and can find very little. If you’ve found it, I’d like to read through it. A link would be great.
Even their sites search mechanism return nothing for even a users manual. They must have something somewhere…
This is directly related to focal length. Shorter the lens, the more shallow the depth of field. A good to know is the beam size before it strikes the lens.
I can’t find anything that gives me any information on beam input diameter, it’s depth of field or the focal length of the supplied lens. Or if you can even change to a different length lens.
2) If there is a malfunction with the red light indicator and it is inconvenient to check the focal distance through overlapping red lights, you can adjust the focal distance through fixed focus method (distance from laser end face to the measured object: 96.1mm/94.1mm).
Interesting here, they imply the module must be on M3 mode? 3) If there are no traces or uneven energy in the engraved vector lines: a) Check if the laser is in the focal position. b) Confirm if it is operating in M3 constant power mode.
Looks like you found it. Yes, Atezr, Atomstack, & Ikier all sell the same thing. I didn’t know the Atomstack site didn’t have it listed. I downloaded and read thru the Ikier manual a couple months ago. Seems odd that the parent site (Atomstack owns Ikier) wouldn’t have it, but whatever.
One of the standard lenses with the Chinese machines seems to be either a 1.5, 2 or 4" lens. 4" is 101.6mm. That gives it about 5mm between the it and the laser end face.
