I am wondering if you guys could help me with a problem I am now facing.
It is related to the laser power.
Long story short, my machine is only capable to make clean cuts at 70% of power. (it was 75% about two months ago)
If I keep the same speed and use 100% of power, the machine is incapable of making a clean cut.
The material I am using is a 3mm MDF.
Note: Mirror and table alignment are correct.
My biggest worry is that the machine cannot cut at lower power than 70%, which mean it will stop work in the next few months...
What I think it is strange it the fact when I output the project at 100% power, the cut is worst than if the project is output at 70%.
- Speed 10mm/s and Power 100% = Don't cut
- Speed 10mm/s and Power 70% = Clean cut
Noticed the speeds are the same?
According to people I have asked in Brazil, they have never seen this issue.
Even if the laser tube is old, they said the 100% power must have better cut than 70%.
I made two videos on youtube showing this problem, one with a 50mm focal distance lens and other with a 40mm focal distance.
They are in portuguese, but I have added english captions.
Hope you help me identify the problems!
