Laser is already down- BCL3766 Board Failure - China Support Process Details -
HTML-код
- Опубликовано: 10 сен 2024
- Got a failure on the BCL3766 I/O board. The laser is down for now. Discussing the china support process on the imported cnc fiber laser cutter from China.
Everyone asks the same question on every video. How much is the laser? Answer - $60K for the one I have. How thick does it cut? 3/8th or 10MM Carbon Mild Steel for the one I have.
If you want to know more info about the machine there is lots of discussion on our Fiber Laser Ninja support group on facebook, click this link to join us there. / 457102398516274

I must say that customer support is huge. Awesome that they are standing behind it.
yes they have been really great so far
Chinease customer support has become better and better over the years. I fried a 700 dollar board a couple of weeks ago on my UV Printer and they where quick to send me a replacement part, even when it was partly my fault. They trusted me to send back the damaged component once I had performed the replacement, never had that experience with tech support, not even in the US.
I am really sorry to hear that,I'll pray that all goes well with you,cheers from Toronto Canada!
thank you
The limit issue is normal, just send all axis to Origin every time you start your machine.
I really appreciate the detail you go into on your experience with this unit. I am considering a purchase and your videos are making me feel more comfortable about pulling the trigger.
I think you just need to keep everything in perspective, and be reasonable about it all, and it will be a good experience for you. join our facebook group and message me if you want the contacts for the one I bought
@@turbocobra interesting just stumbled on your videos. We build both plasma, wood multi tool changers and lasers from Nairobi Kenya . We can link up and share some stuff but will chek out your face book page our page is as follows facebook.com/proteqautomationltd/
I bought a 100w fiber laser from China $5500 and 2 weeks later had to send the laser back witch cost $340 to send. The day I sent it back I got the bill for the tariff $1131
Don't forget about the tariff
You will get it dialed in. Your making parts already :) Remember that! I’m glued to your posts lol
yes sir thank you
The cut looks good. Pierce condition should be adjusted for the small holes to improve the quality. Having issues with a new machine is not unusual. Let's hope you get the part quickly and it is covered under warranty.
Hi, for pierce try the next settings. 1000ms step, 1000ms pierce time. Hi power (90%) Low gas preasure (20psi), Pulse pierce (10hz) and a pierce hight from 5 to 10 mm
It sucks that it is broken but it really shows how great their customer service is.
I hope you get her light saber going again real quick. lol :-)
Thanks Cecil!
The cuts are very nice glad you’ve got some good support.
thank you sir!
thats mighty good service , great for you , and a great add for them
yes sir thank you for watching
looks like there's a power led right next to the screw terminal, unless the terminal is bad or the PCB broken right next to the terminal it makes little sense that it doesn't light up. There's not a whole lot going on on that board apart from relays and wires
i agree
those 1/4" holes should be fine. Tune in your settings perhaps. I regularly cut 7/64" holes in 1/4" plate and they look nice
Glad they sorted it for you, hopefully does the trick
yes sir thank you
Most of the time i get laser heat overheat what could be the solution for this?
Nice to see your getting this piece of machinery running. I'm guessing this machine purchase was solely for business manufacturing. Yeah I wouldn't a laser cut precession holes, especially for machining purposes, slag can hang up and just make them look like shit. Which was why I was surprised you went the laser way, and not a CNC route. Good luck with it, curious to see what your gonna pump out on it.
when setup right, laser cut holes can be a more true hole than a drilled one and completely dross free. The laser surface edge is not hardened and nitrided like plasma and oxy fuel so it can easily be setup for second op machining
On our laser we try to stay away from holes that are smaller then the thickness of the plate. IE 1/5 plate = smallest hole at .25. What we will do on a production run is make a drill template out of 1/8 (in this scenario) or any scap really that would be under .200. Then gang drill the parts on the mill. But I can say that I have pushed this "rule" for fun projects. Learning and relearning the capabilities of your machine is paramount. Also try coating the steel with Marvel Mystery Oil to eliminate spatter on piecing. And try turning down the pierce and cut wattage for those holes.
right. I think the 1KW power source is the limiting factor on this. A 6kw would pierce much more cleanly
@@turbocobra do they have a 6kw option for this machine.
On something that technical. I personally would have paid the premium for a US based company. So when things like that happen. They send a tech out and take care of it. Nothing pisses me off more than language barriers
There is no guarantee you will get better/faster support from american companies. Many american plasma table companies provide terrible support. But yes, when you buy your laser, if you have $150K to spend vs. $50K to spend, by all means go for it!
Yeah, at $400/hr with travel and lodging covered? No thanks! It just sounds music to ears but money saved is always MONEY IN THE BANK!
Awesome your getting some more cut time in 👍👍!! On your hole issue in 1/4 inch or anything where you have a hole about the same size as the thickness of the plate you are trying to cut you will need to cut that hole under a medium or small contour in you cutting conditions or however it maybe laid out on that laser. That should help in dialing in the laser on small holes. You should at some point even be able to do 1/8 holes in that 1/4 in plate if you really wanted with pretty good quality. Getting settings right can be tricky since you have wattage frequency gas pressure focus etc. To take into account.
right i knew that was the case for Plasma, but was thinking laser wouldn't have that issue. I think its the 1KW power source. If i had 6KW its got the power to pierce with less surface disruption.
We bought ours from a USA based company and their support is USA based and very helpful. We've had very minor issues with ours. On the holes, for thin materials you will likely need cobalt bits. Laser cutting makes it harder than stainless and will ruin hss and coated bits in a skinny minute.
On your pierce into 1/4 are you using a multi step pierce? Or multi stage? With a 1kw machine that pierce may need 3 to 4 hits starting at different heights to get through the material before you start cutting. Email me at mark@alphidia.com if you want to work through this. Happy to help.
Maybe should have had them send 2 boards that way if it has another issue you aren't down weeks waiting for it to show up.
yea your right about the t
Oh, that looks like it's your Servos IO board, it transmits the signals from your motion controller to your servo drivers, and your servo drivers closed-loop signals back to the motion controller. And based on the relays I guess it also controls all other analog functions.
Too bad they slapped everything on one PCB instead of having an axis/function-based breakout layout :/
You would be a good friend to have.
@@alaskanken2132 Having a sarcastic industrial mechanic as a friend?
Nah, ask my friends, they say I'm a pain in the butt ;)
Well you sure sound like you know what you're talking about 👍
@@alaskanken2132 Well a bit, comes with the job XD
I've never worked with Laser Cutters, but I've worked with and maintained various industrial CNC machines as part of my job. But those were mostly either older german made high-end systems, or more modern. The old german ones also had breakout boards for various functions similar to this one, which we had to fix a lot over the years due to their age. The modern machines all had optoisolator boards for all functions, which then lead directly to the drivers, solid-state-relays, etc. Those were a blessing to fix as every time something did break you could be 99% sure it was something behind the optoisolators, the motion controller was never the issue as it was protected behind those optoisolators in its own shielded casing.
So, all in all, I've never worked with this style of a machine, but I probably could figure out what's wrong with it and fix it since it used to be part of my job. Remote diagnosis is sadly very hard on things like this.
man your right, that board has alot going on with it
Did you seldom use the machine for tube cutting? I saw the pipe cutting attachment and the plate cutting machine tool are not placed parallel, which will affect the accuracy of the pipe cutting.
Hi , Just started following this , very Helpful :) Can you tell me what company you bought from ? Im looking at buying one soon. Thanks
Yes, Primapress
Friend, what are the cutting and head parameters that you use to cut that thickness?
Hi mr Ramsey, my brother has just recieved the same 1kw laser from China. He has a Cnc plasma but this is a new ball game. I’ve help him instal and set it up but we are really struggling with getting gas pressure, current %, power % right just to cut some 4mm sheet to a decent standard. We tried the pipe cutter with some box section but that mostly made mess. We’ve had no luck with piercing at all. I was kinda hoping you might give us some setup details for various material thicknesses to get us started. As you know the chinese manual ain’t great. Hopefully you or someone else would like to help. Cheers
So why did the board fail? You showed some less than ideal wire termination in your previous video, the result of them sending you cut cables. It wasn't clear to me if those were high voltage motor or low power signal cables. Regardless for a CNC machine like this (and at this price point), all of those wires should be shielded and run uninterrupted from the motor/encoder/limit switch back to the controller. If they are split, should go through a proper shielded connector. Are the cables even shielded? What I'm getting at is I hope that the poor termination isn't picking up interference and taking out the board. I guess you will find out if it was a one off "bad board", or a reoccurring problem soon enough. Good luck, thanks for sharing.
my guess its a defect in the board somewhere, maybe a cold surface spot or something. I understand everything your saying about the wiring. The wiring going to all of the motion control components appears to be shielded and the ones going to things like limit switches do not seem to be shielded. I understand that unshielded wiring could lead to erratic behavior of the machine, but i dont understand and dont see anything in that machine that would lead me to believe it would cause a board to fail
60k, but it can cut 10mm only? how much power?
I don't know if you know but your address is on show near the end of the video.The support seems excellent, don't worry you will have the machine up and running again in no time!probably just a step down regulator died on the logic board
You can get his address by just googling Ramsey Customs, his company, so I guess it's not that big of a deal.
Dont be stalking me! lol. Yes, all of my information, phone number is all public.
Hope all is well,did you fix it?
do you have a plan for drilling holes you have pre-drilled with the laser and got hardened? do you use carbide drill bits?
yes i have some carbide drill bits, but wont need them. the inside of those holes don't get nitrided and flame hardened like plasma holes
@@turbocobra oh interesting, I had bad experiences with laser cut holes.
Does the laser harden or temper the metal in the cuts? You've definitely got a lot more faith than most going Chinese on that machine. Hope it works out. Thanks for sharing
from my experience it air hardens steel. I don't know for stainless.
Thanks for doing this. I also am looking into getting one of these. Someone has one in a shop local to me and he was having problems with smaller detailed parts too. This is the main reason I want one to do smaller detailed pieces. It should cut cleaner 1/4" holes I would say, did you ask them what the deal is?
Yes, i think I can get improvement on that with a better piercing routine. Although this is a 1kW power source, and a higher powered machine should be able to pierce with less surface impact. Thinner materials do not require a pierce and can cut with very little to no leadin
On the board bcl3766 is there a X0 wire that goes to the middle between x- and x+ like the Y side has y10 I am just looking at the print of the board and was trying to look up a few things for you
Thanks Doug!
Looks like your nozzle centering is off and your focus for pierce is a little off, otherwise you should have no problem doing .1" dia holes. on that 1/4" Just need to slow down movement, fix pierce and pulse around the hole.
agreed! or pulse pierce into the metal first and then continue cutting...a lot of slag can be prevented by dialing in your focus, cutting power, speed and oxygen supply.
I did a tape shot test and it appears to be centered up, but then again I am new at all this
Is a fiber laser much better than co2?
for some things, yes, for some things no.
If I were a metal fabricator shop which one would be better?
Chinese brands are not the same , do not pick too cheap one and must consider how well known the company is
They literally have 100s of companies making laser fiber cutters and none of them are popular. It's a gamble.
@@Z-add they are good brand too , at least listed on stock market , Hg laser(Farley laser) is listed on stock market , they have 40years of history in the field of laser device
Ya you need to work on the piercing. Look at the gas PSI/BAR on your piercing, it is way to hot.
Right, it needs work. I had it set a lot lower starting at .5 bar and .6 bar for the 2 stages, and had to keep raising it otherwise it would never pierce and just make a mess. This is only a 1KW power source
Ramsey Customs - turbocobra
If that is the case then you will need to work on the frequency and piercing height, step 1 would usually be around 8mm and step 2 around 0.8 for me.
I understand that it doesn’t have a lot of power, that means might have to compensate with longer time.
Love the videos man keep it up.
Replace it with a Pi!
Most of these types of boards have a FUSE right after the VDC_IN...that is generally there to protect all of the other, more expensive, components on the PCB. Try and see if this FUSE exists, and if yes...try to bypass it with let's say a similar size or a little larger automotive FUSE like I did here: imgur.com/iw1a4ZV. Maybe that will get you going?
New board is coming today, but definitely good info, should have looked more closely for a fuse
You still Love Chinese products?
Aww man, I am dependent on it just like you are
@@turbocobra Luckily in Wood Working and Car Restoration I have old tools I count on, but dealing with Chinese made parts kills me all the time! I love your work and attitude.
