I have a 90W Reci tube Chinese machine that I just got in a few weeks ago. Hasnt been used very much,less than 10 hours so far..but Ive been cutting 3mm ply today. Got through a few orders and all of a sudden it would no longer cut through at the settings I had been using all day. speed 28 / Power was 80/65 ,and the meter around 28ma .
all I did was change wood ,been cutting the same patterns most of the morning.
Now I cant even cut through at 5 speed and 100% power. doesnt make sense why the sudden change without doing anything...but checked the mirrors anyway still good. meters still reading around 28ma ...any ideas?

Is the laser tube "S" series? Check the manufacturer date. If it is some where less than 9 months old but older than 2 month, chance is that the tube is defective. It is because Reci got production problem since a year ago when they launched the "S" series

Simple test: put a piece of wood in front of the first mirror and fire the laser up with 28mA. If there is a good burning mark, chance is a bad mirror or lens. If it doesn't burn, you know what I mean
