xTool Infrared Laser Focus

xTool Infrared Laser Focusing

xTool Infrared Laser Module

I purchased one of the xTool Infrared Laser modules and while it is super cool there does seem to be some internet chatter that the manual focusing mechanism is not 100% accurate.

There is a flip down bar that positions the laser 20mm from the work surface however the optimum focal range is 1mm or less.  That means even a tiny positioning error can greatly reduce the effectiveness of the engraving operation.

There are a few strategies for manual focusing the module however the best of the bunch in my opinion is to use a USB microscope to visually dial the beam down to the finest possible size.

I purchased a USB microscope from Amazon a long time ago for my first laser I owned and had to knock the dust off of it.  Set up is easy however software doesn’t really exist but the microscope works fine on a Mac with QuickTime Player.   It used to work with Photo Booth but doesn’t really seem to anymore.  It takes one still shot and then disconnects on my M1 Macs.

Aim and Observe

I wish I could give some kind of detailed, highly technical steps but the reality is that you just aim it at the laser dot, hit fire, and move the xTool Infrared Laser Module until the beam is the smallest you can get it.  You have now achieved optimum focus.   Here is a video for clarity.

Ortur Laser Master 3 LE Review

Ortur Laser Master 3 LE Review

I’ve been doing desktop diode lasers since they became mainstream in about 2019.  Prior to that they were mostly DIY.  Ortur was pretty much first to the game with the Laser Master 1 and subsequently the Laser Master 2.  I owned 2 of those.   I’ve since picked up a Laser Master 3, an Aufero 2 and now it is time to do an Ortur Laser Master 3 LE Review.

I wasn’t really a fan of the Ortur Laser Master 3 and I wrote at length about that here.  My LM3 works fine but I generally think the design has some issues. It sits so low as to be almost unusable for anything over 400mm in width unless you raise the machine. Also  there are support issues regarding the lens protective glass that just aren’t right.

Unboxing And Assembly Video

HA!  I don’t do that here.  Ortur lists what’s in the box on the product webpage and they have a great assembly video.  Why people think showing what’s in the box is useful in a video when those components are listed in a chart, I’ll never know.
