LaserUser.com Forum (formerly RDWorksLab)

My name is Joachim, I am from Germany and just a beginner in laser cutting and engraving.

I already bought a chinese laser but I not agree with the mechanical quality of the machine.

What I am doing now is to upgrade the machine: mA-meter, new mirror holders, different laser tube holder,
beam combiner, replacement Z-Axis chain with 4 servos ...

I was watching youtube to get more informations about CO2 laser and I found this forum.

Welcome Joachim- I assume you are watching Russ' videos online? As you have found many Chinese lasers need some improving to become useful machines. Read the FAQ section and if you are comfortable with English, our translated manual may be useful. Ask whatever questions you may have and we will try to help. Gene
