Is always tough to hear people having bad experiences.
Hopefully the mind hive here can conjure up some ideas.
I am not 100% familiar with FS but my initial thought would be for a controller conversion.
From what I understand, that shouldn’t be “too” difficult, but would need some tinkering.
We have fantastic people in the forum that have high levels of expertise and I am sure they will share some ideas.
What i would suggest is you get from the machines a few pictures - specially of the power supply - and the controller box space. To see what could “fit”
In other words, to get an overview of the machine with pictures will help others visualize potential solutions.
Awful is an understatement. The recordings I have of their owner telling me he sells 500K- 1Million dollar lasers every month and he doesnt care about these stupid 10K lasers was mind blowing. Its awful and having 2 50w Units I cant even use just sucks.
The only thing I am not sure on is the Raycus Laser source. Having looked over it I am not seeing much info. I really hope I can convert them and people here can chime in. I used Light burn on our C02 and it worked perfect. It would be nice to use it again and have functioning units.
