Nah, read switches and /or proximity sensors on pneumatic rams etc to feedback that they have got to their position. Easiest example is on the dust hood of a CNC router. In this case, the machine needs to see the dust hood is open before doing a tool change to prevent collision. It doesn’t take much for read switches (magnetic, on the rams) to fail or need adjustment.
I spend literally my entire life servicing and fixing machinery, mostly CNC routers and edgebanders in joinery shops but also classical machinery like planers, setting up table saws and the likes. Past life was industrial electrical with a lot of machinery alterations to bakery equipment and breakdowns but also many other industries.
Most electrical faults I just leave the meter on AC volts and if the contracts are closed the induced voltage fluctuating on the screen drops to zero. Don’t even need to take the time to understand the circuit or applicable voltage. If that doesn’t work, I apply more effort.
This is an edgebander, I spend half my life servicing these now:
You were right in the sense that there was one proximity sensor that was being tripped.
In a separate alarms page that I found today not the page showing the codes
But the proximity sensor doesn’t really have a proper coupling. It’s literally sitting in this hole on the side of the capsule hopper (to determine if it had capsules in it or not) you would think it would atleast be held by friction as the machine does emit a bit of vibration. And can jostle the sensor around throwing a faulty alarm when running. I gotta probably secure it properly as it’s gonna be a bitch as I get it closer to operating condition.
I ended up bypassing all the alarms and error codes, jogged the machine via manual step cycle getting it to run without air which was a crazy move. Considering there could have been something impeding movement or the chance the turret was out of alignment. I was trying to move the turret to with the hand crank yesterday and it felt like it was completely binded but I believe that’s because the handcrank was engaged. I somehow got lucky and accidentally disengaged it in the proper spot at a station where it didn’t throw the whole system off.
I didn’t know how to check so I said fuck it press the “inch” it forward button.
Tomorrow I get after chasing the open pneumatic loop which I’m afraid might be the largest can of worms as if its not done right it will crash the whole machine & damage the tooling.
I have no freaking clue what I’m doing so I gotta try and be super methodical about it, read through the manual best I can which I still need to get ahold of but also in a rush as we have two separate customers that wanna buy this machine.
Ahahaha
That is super badass
I admire the expertise you’ve got!!!
I’ve never even heard of a edgebander before
My family deals in new and used nutraceutical, pharmaceutical, cosmetic, processing manufacturing equipment.
As well as packaging & lab equipment.
I’ve got a lot to learn being that I’m the fifth generation in the business.
If you learn one thing a day you’re gonna do better than most people. I think that bits important.
I’m 41 now, and the skills I’ve learnt actually make my life harder because the expectations increase, as well as the number of people who hold them. I’m on another plane Monday morning for work. New Felder table saw to install, and some warranty work on another. They’re expensive saws, about NZ$60k for a saw with PCS.
I hope you get the machine going. People ignore problems when they know they’re replacing it in six months time, and it’s very hard finding third party engineers or electicricians who can work on a given machine - yet alone both!
I’m kinda odd, I love to make friends with corvids( I know he is a raptor). I’ve been seeing this guy, I bring him rats I kill at home, this morning, he finally got what we are doing. As soon as he saw my car he flew down
I’m safe, I don’t have much hair and I eat lunch in the Hitachi, pretty sure I could probably pluck a bird out of the air if they get squirrely on me the Corvids that I’ve made friends with bring me shiny shit as presence and return for whatever is left in my lunch
That’s one of my favorite birds. I’m very jealous. I’m pretty sure I’d be more excited to see that bird in the wild than any person on earth you know celebrity wise.
