I am getting an intermittent water protection error on my shenhui dual tube.
I am currently only using one of the tubes. Last night i started a 30 minute job engraving plywood and after about 5 minutes the laser stopped with the screen reading "water error". For any error you can reset the machine and the job should restart where it left off.
My cooler is the CW5200 for dual tubes, it runs water through both tubes, and the laser has 2 protection switches, one on each tube loop.
Sometimes after a reset the laser would start again and sometimes not. It seemed to run better if powered off the board.
If the error happens, then I try the pulse laser button the error then reads "water error 1"
Could this be a moisture problem. There is a possibility that one of the water connections near to the protection switch leaks. (Not enough to identify which one leaks, I need to re clamp all of them)
Do i need to replace both switches? Since i don't know which one is faulty?
any ideas would help. Thanks. Marty
