There wasn’t a hole through the panel for me to run the ethernet cable so I drilled a 1/2’ hole to run it through. I thought I was good and clear, but the bit caught and ran all the way into this black wire. if you look close you can see the cut, sparked and smoked:-(
There is very likely a fuse integratred into the power cable connection. A quick google search turned this up. Make sure you repair your wiring before replacement.
That’s what I’m struggling with too. I have the manual believe it or not, even though it’s three times used. But it doesn’t mention the fuse or the size. going on people’s advice and the person that used to own it, he thinks it’s a 15 amp fuse. But they’re different fuses than automotive 15 amp fuses so I’m trying to find one . My neighbor is running around trying to find one for me as I just had eye surgery and I can’t drive. We’ll see what he finds but I’m looking for a 10 to 15 amp fuse.
You could check the power draw from the motor drivers and the laser’s high power supply and use the currents they have to roughly approximate the fuse size.
You want the “fast blow” variety for electronics, not the “slow blow” variety for motors. There are also ceramic versions less likely to shatter under duress, which is what happened to yours.
Of course, there are several “standard” sizes. Measure twice, because the fuse must fit the holder correctly = snugly to ensure a good connection.
Thank you all for your help in diagnosing this problem. This form is the best I’ve ever seen for its accuracy and it’s help.
I was able to take the two pieces of fuse out. I could not read them.. I just have cataract surgery yesterday. My neighbor could not read them But my neighbor tried over three hours. he ended up at Grainger And the old fart behind the counter says nope, then some youngster spoke up so let me see that. he was able to see the number on it and went right to the Parts catalog grab the fuse! they’re expensive five bucks apiece. I had to buy a box of five, but put it in and it comes on and works great!!!
And for safety sake, I’m still ordering the power filter that was recommended.
Thanks for getting me to check.
They put in a 30A fuse! (and another 30A spare, nice of them!)
A recipe for disaster?
I put in a 5A (more than enough).
I’m NOT using the “accessory” outlets at the rear.
I’ve already rewired the IEC socket (H & N reversed)
Ultra-skinny (either 18 or 20 gauge?) unmarked wiring.
Well for a sub $500 unit, what does one expect?
Going down a rabbit hole every time I inspect any parts.
Stripped screws, panels put in backward, etc.
It DOES burn holes though!
It’s been a long while since I measured my machines current load. I don’t use any of the outlets on mine either. Mine draws a little over 2.5A running a job on a 120V main.
I’m going to order some 5A for mine and see how it works out.
Finally found it at Granger, first a older guy said don’t have them, then a youngster behind the counter knew what it was and had eyes good enough to see. It was 10A
but I am trying.
