Got my GF yesterday and have proven that “proper” setup within an hour is impossible unless you have some minor (major) details already taken into consideration such as, safely powering and protecting your $4000 investment.
I was getting ready to plug it in and then this Step through me for a loop:
Plug in your Glowforge
Plug the Glowforge into a grounded wall outlet with 800 watts of power available. Make sure you connect the printer directly to a wall outlet and not a surge protector or power strip.
Problem: I live in Florida, brown and black outs all the time. So the internal surge protector from the GF is ok… but being in Florida I don’t want to have to start/stop jobs all the time nor beat up on the internal surge protector. No idea what the GF warranty on the surge protector is but I’d rather not have to find out the hard way. (And even if it is covered, it’s only for 6-12 months)
Due Diligence in a nutshell:
-Read through GF community posts
-Google’d technical info & best practices with UPS’s
-I can’t find any battery backups that don’t have outlets without surge protection.
-I HAVE to have battery backup ability.
-I HAVE to accommodate both the internal GF surge protector and the external one bought separately.
-My conclusion on issue with daisy chaining UPC/Surge Protector:
-If you daisy chain two surge protectors you MUST consider that the 1st Surge Protector (In this example, the internal GF unit) can mask the actual power output of the unit it’s protecting.
-Making it so the secondary Surge Protector (External UPC) can be overloaded beyond it’s capacity which can cause serious damage/fire, possibly immediate if the UPC enters batter backup mode AND is overloaded. This issue is intensified if the UPC is dispersing available power to multiple plugged-in electronics.
So the resolution to my dilemma is:
-Bought a 1500va (900 watt) UPC ONLY. Again, UPC ONLY for the Glowforge. Nothing else will ever be plugged into this UPS. Guaranteed to accommodate the 800watt GF rating & leave room for error between both Surge Protectors. If the UPS is dedicating all 800 watts to the GF, unless the GF has the ability to spike over 900 watts and hold it, I don’t see why this would ever be a concern.
-Unplug the machine when not in use.
-After using GF, check for any sort of abnormal overheating of the UPC, power cables and outlet.
I by no means am an expert in electrical work. But by reading numerous posts in the GF community and doing my own research on UPS’s I feel confident about my conclusion here.
Please provide your feedback and/or support. I’d love to get more affirmation on this solution.
Maybe GF can also confirm a black & white method where a user can safely and effectively use their GF with an external battery supply.
