@riumplus if you’re still around, maybe you’d like to chime in on the water situation? Previous owner said they were told to use only distilled water and change it every 2 weeks. They just used tap water through a carbon filter and changed it every 2 weeks as advised.
I believe you use some manner of additives in the small laser cutter water loop to keep the water from fouling, which I’d imagine we should do rather than trying to constantly change the water in this.
