For the last year i have had my laser in use at my day job, I have now taken it home as i’m leaving the job. It took two of us a long while to get the laser upstairs to its new home, got it all back together, controller works fine, chiller works fine, blower is ok, turn the laser psu on and… out go all the house lights:(
We have RCD’s on all circuits here and it tripped the one running the main power sockets.
I am guessing the PSU has some minor leakage current which did not matter at work as no RCD’s.
Anyone else have this issue, did you fix it??
