thank you. APC is the UPS brand - been using them for 25+ years to include back office servers via intranet and unix/linux class web servers and can’t ever claim an issue other than from time to time battery replacement. I started UPS on the 3D printers back on the 8 bit boards and there was no file and or print recovery to turn on or off. the data send to file write process for that reason of recovery I just turn off if I can. A lot of those features I turn off due to the lag time that can happen. Just give me straight run and power on all the time printing. Yea, there are big print outfits that I could send my prints to in the MPLS/STP area (1 hr +away) - you know the big names too. I’m a maker tinkerer who likes to take long run time prints more or less at home. I’ve heard of Duet3D and will be learning what I can there. Prusa might have to be what I head towards as they seem to have products that upgrade the firmware even on older machines as I have read about. Later I guess…
