Weak Laser after one year of use
After one year of use, ()Non-business use), The laser is only 1/2 as strong as it was when it was new. The cutting speed for 3mm MDF board at one pass is 200 speed at 100% power. I use full airflow almost all the time. When I first received the Ikier K1 Ultra 36 watt, it would cut the 3mm MDF at 600 speed and 100% power in One pass. Laser failure at maybe 1000 hours of use and Rarely used at 100% power on the laser. Most of the time I used 85% power and increased the number of passes. I have cleaned but Not replaced the lens (Have 3 on order) and will see what this does.
