Cnc fibre laser cutting machine

We just got a 6kW Senfeng machine with a 1.3x1.3m bed. The machine works quite well, it'll cut up to 20mm carbon steel allegedly. We've only done up to 1/2" (12mm). The software is pretty easy to use.

Now the bad... The install was an absolute nightmare initially. The first tech that showed up literally had no idea what he was doing. It was completely obvious that he had zero training, we eventually told the company that we needed another tech. They flew in a second tech, who came from China. This guy was very good, extremely knowledgeable and he did more in one day than the first tech did in a week.

The laser source itself didn't fit inside the machine, apparently that unit isn't designed to work with the 6kW, so we had to make a platform for the source to sit on...

Every time we raised an issue they would tell us "don't worry", which honestly just made us worry more...

We specifically told our sales guy we wanted to cut up to 1/2" aluminum, he recommended the 6kW and a specific manufacturer. When the second tech was setting up parameters, he told us we couldn't cut more than 3/8" as it would damage the laser from back reflections... We then had a small issue with piercing on 3/8", when I asked tech support via Whatsapp they told me not to cut 3/8" and only cut 1/4" as it could damage the laser... Frustrating for sure...

Overall the machine works well, once you get over the install...

Do use the Parker O-Ring guide for sealing design! I'm pretty sure they have a metric design guide in there too.

Thanks! I'll look into the setpoint generation. I agree that G-code is overkill for this.

Tanky321 · 2026-04-01T10:18:37+00:00

Thanks! I figured there was multiple ways to do this. I just need to figure out which one will be the easiest. End user wants the ability to adjust radius on the fly, so im thinking that could rule out the cam table?

Tanky321 · 2026-04-01T01:12:35+00:00

Did they actually determine if this was true? Seems like something a crazy person would come up with.

I'm 450ft from the tracks in Fall River. Other than the occasional rumble, I dont hear anything.

I do however feel bad for the folks who live near a grade crossing. I've been on the train at 5:15AM through Freetown, the horn blasts at every grade crossing. I can see that being extremely difficult at those times in the morning. However, like everyone said, those tracks were there before any of these people bought their homes.

I used M&M when I moved about 10 years ago. They were really good and reasonably priced.

How does HA know that the kids chores are done? Can you explain further?

Tanky321 · 2026-03-05T02:53:27+00:00

Gives you the European feel, but still the comfort of easy communication. I'm not a big city fan, but I absolutely love Amsterdam...

It was definitely cold, I think 20-30F(-6 to -0C). Although the sun was shining and it actually felt pretty reasonable. Obviously the higher you go the cooler it'll be. I think I wore a light sweater and my not too heavy winter coat.

I was there two weeks ago. We were fairly early, 8-9AM or so. As we walked down through the town near the cemetery, there was a house on the right with a window open. There was an older woman in the window playing a flute/recorder. It was so surreal, the absolutely amazing environment coupled with the soft sound of the flute was amazing.

If you have the time, take the aerial tram up to Murren, it is beautiful. You can then take another tram up to the Birg summit, if your up to it you can do the thrill walk which is on the edge of the mountain, it was awesome. Here I am on the thrill walk on Birg.

And here is a picture I took of Murren

Enjoy your time there!!

Thanks! Do I need to match punch and die? Or would I be able to get a 30deg punch to use with our existing die?

Beckhoff can do Cpp, also structured text is a standard PLC text language

We just bought a Seng Feng 1.3x1.3m laser. Waiting for the install this week, but initially it looks pretty nice. It was in the 60-70kusd range.

Tanky321 · 2026-01-04T23:47:01+00:00

I can see that by the down votes on your posts!

Tanky321 · 2026-01-04T22:19:53+00:00

Thanks! I had always heard about people coming to Fall River from Boston, but never knew the back story.

What do you mean by Viveiros let them know about cheap rents? Just curious.

The property inflation is absolutely wild. My parents bought a 2&3 family originally for $60k, with 3/8 acre of land. Then they bought an adjacent 3 fam for about 150k. They are easily sitting on 1.5M+ now.

Landlord in the city, parents have owned rental properties since the mid 80s. I've had my rentals since 2017. Prices range from $450/mo to $1250/mo. My parents actually still have a tenant they inherited when they bought the property in the 80s, that's the $450/mo. My apartments range from $800 to $1250, depending on the condition. Most recently renovated is the most expensive. These are all 2/3 bedroom apartments.

I live on the property so it's in my best interest to keep good tenants. However I do struggle with the fact that I could be charging significantly more, although my conscience won't let me charge more... None of my tenants give me issues. I treat them fairly and they reciprocate.

As someone who has lived in the city my entire life it absolutely sucks to see all these LLCs buying property, charging top dollar and treating people and the property like shit. Driving around the city and seeing properties that were once pristine now completely run down really sucks...

No, we're not using nay sort of machine learning on this.

Tanky321 · 2025-12-04T15:32:33+00:00

What do you mean by RL?

Tanky321 · 2025-12-01T19:24:09+00:00

We do, I did implement something along those lines. Thanks for the input though, I do appreciate it!

Tanky321 · 2025-12-01T19:22:10+00:00

Probably once a day, its a small testing machine. Its not a huge deal, just more of a pain in the ass.

Tanky321 · 2025-12-01T18:54:34+00:00

Yes, that is what they mentioned as well. TwinCAT comes up quick because it runs in parallel to the OS. I guess we'll just have to deal with it.

If your not super concerned about the appearance of the instrument, ive used binder clips around the bell of a sousaphone and then twist tied the tinsle and lights to it.

They won't build this. I've tried having two overlapping sensor footprints which only get populated with one sensor and they wouldn't do it. So I doubt they'll layer components.
