Say no to sticky tape!  Until now the only way to align mirrors on your laser machine was by sticking painter’s tape, burning a spot on it and then painstakingly trying to figure how how much off your beam is from the center.

We’ve developed a custom alignment tool set that clips on mirror holders. Once attached all you have to do is insert a piece of thick paper (target indicator) with cross-hairs and pulse your laser.  Burn mark will show precisely how centered your mirrors are. If it’s off turn adjustment screws of the mirror that delivered beam to the target to compensate.  Then repeat process until it’s dialed in.

Process is essentially the same as aligning with adhesive tape, but with no mess and total precision.

Swap target indicators as needed and use as many as needed. Make more from a cardstock on your laser, template and settings is included in the links below. You can even print them out on any laser or inkjet printer and cut with scissors in a pinch or order more from our store.

  • Attach larger bracket to 1st mirror to align your CO2 tube
  • Attach same bracket to 2nd mirror to align 1st mirror
  • Attach smaller bracket to the laser head that holds 3rd mirror to align 2nd mirror
    Insert it into large hole, but DO NOT push it in all the way, just as long as it stays in it’s fine!

What’s new in Version 2:

As we discovered each Boss Laser machine had it’s 3rd mirror holder mounted differently. This created problem with mounting 3rd mirror alignment tool with some users.

To address this we redesigned 3rd mirror mount from ground up and now its simply gets inserted into big round hole. Mount has been designed to fit 3d mirror mount hole diameter of approximately 20.5 mm.

How To order

When ordering please choose following options:

  • “Full Set”  includes alignment brackets and 15 paper target indicators to get you started.
  • “Brackets Only” is bare bones option. You’ll get plastic brackets, but will have to make your own paper target indicators (template is provided in the links below)
  • “Extra Bundle” same as “Full Set” but includes 30 more paper target indicators (30 total) for just $5 extra.

We also offer just paper target indicators as separate product.
All brackets are 3D printed (colors may vary) and while we keep small number is stock it might take a day or so for us to make more depending on number of orders and machine availability.

This product is proudly made in USA.

PLEASE NOTE: Below video shows Version 1 of 3rd mirror mount, we have since updated to better one (Version 2). We’ll update video soon.
