DIY Fiber Laser Cutter V2 | Part 7: Raytools BM110 Auto-Focus Cutting Head

If you want to build your own fiber laser cutter, join our Patreon group: / diyfiberlaser
Today we install the homing switches, set up the soft limits, and attach the Raytools BM110 auto-focus laser cutting head, along with the cables and hoses, to get all of the mass on the gantry in preparation to do the Leadshine servo motor tuning.

Hey Travis, you found a perfect way to solve the collision problem.🎉

[@flpsht]

A tip regarding the watercooling, have the input be at the bottom and exit at the top. this makes bleeding the air much easier. Especially with lower preassure and tighter tubes. This will be a non-issue with enough pressure ofc.

[@diyfiberlaser]

Thanks for the tip!

[@CraigHollabaugh]

Looking good, using the fish tape for spring steel is clever. Just heard from SkyFire, my order is ready to ship. Thanks Travis and SkyFire.

[@AndrewPrice2704]

Skyfire have been very helpful to me too. Wish i could place my order right away!

[@Iamtherodlight1453.]

Simply amazing thank you for making this video and the others in the series

[@spencercoates9067]

Can’t wait to see this thing fire up. Thank you for a great in depth series.

[@xyzspec82]

That's a lot of cool toys 😅 The machine is looking very good 😊

[@weldchip]

looks like you made some good progress since the last video.

[@the1maxb]

I'm sure you'll get around to trimming and re-terminating all of those super long cables eventually, as they'll not only look neater but be less prone to emitting or picking up disruptive EMI/RFI. Until then, stacking coils of current-carrying cable against delicate signal cable could cause trouble.

[@diyfiberlaser]

Thanks for the advise!

[@petergamache5368]

You don't want to loop your motor wires like that. You're creating a coil == an air-core inductor. Instead of circular windings, make long back-and-forth loops.

[@diyfiberlaser]

Thanks for the tip!...I'll see what I can do about rearranging them.

[@Bassam_Nabeel]

I would ask you please how the orgin function work? I have a sensor for each axis x,y and z all of them are working perfectly but the machine doesn't stop when the sensors are on. Btw all the sensors are Normally Open.

[@diyfiberlaser]

They need to be wired to x0, y0, z+ pins

[@Iamtherodlight1453.]

How big do you think one can make this particular set up that you have made? Do you think a 4‘ x 4‘ or 5‘ x 5‘? Would it be applicable?

[@diyfiberlaser]

I don’t know…you can get the C-beam heavy in 1500mm length…i imagine you could build it with some additional bracing

[@charliew.1122]

would it be worth 3d printing a bumper for the hard stop around the optical cable, to make things a little gentler if it crashes?

[@diyfiberlaser]

I started to do that, but I’m concerned the plastic could break under the force. That cable is the most expensive part of the machine, so I don’t want to risk it

[@stocky9218]

Coming along nicely, will you share a total cost once the machine is completed?

[@diyfiberlaser]

Of course...I'm at about $10,500 right now, I'm almost done...just have a couple hinges and some sheet metal for enclosing the machine left to buy, so it will probably be around $11k all in. Also, that number is with using a cheaper brand (same specs) servo motors...the ones I was going to use before the sponsorship.

[@stocky9218]

@@diyfiberlaser That's a pretty reasonable price, thanks for the reply. It's looking great so far and I think I might take inspiration for my next build from it. Keep it up 👍

[@Bengkel_Reklame_Indonesia]

helo Travis is the home limit disconected to Power supply?

[@diyfiberlaser]

The laser head homing switch is connected to the Raytools controller.

[@Bengkel_Reklame_Indonesia]

@@diyfiberlaser yes but the limit switch doesnt work without 24 v

[@nerdulator5000]

I'm really looking forward to what you think about the xc3000 controller. Do you know if it supports obstacle avoidance, where if a part pops up it will avoid it? Im debating between the fscut2000 and the xc3000. I had a rep from raytools send me the comparison between the two and it almost looks like the xc3000 may be more robust.

[@diyfiberlaser]

I would assume all fiber cutter controllers do that, it’s how the capacitive sensor in the head works to achieve consistent height, even my Ruida controller on my other machine does it, and it doesn’t have near the feature set. If it does touch, it just pauses and throws an alarm. I have yet to test it out on the xc3000, but I’m liking everything I see about the controller so far

[@nerdulator5000]

@@diyfiberlaser I think I may be leaning toward that same controller. Here's a couple of examples of the obstacle avoidance. It's what they call automatic intelligence obstacle avoidance. One of them is on the xc1000, so I would hope the xc3000 could do the same? Looks like a really nice feature! kzbin.info/www/bejne/n162npKlpLKIntEsi=cvYFvCP5PkxD0goy kzbin.info/www/bejne/nnK6qZ2ol7KdsNksi=wEyWWdtcq2EcXXr5

[@diyfiberlaser]

@@nerdulator5000 Thanks for sharing the videos. After watching them, I get the feeling that "automatic intelligence obstacle avoidance" is probably just marketing lingo. They both appear to just be setting the lift height above the part stickup height on their demo pieces and then when the nozzle moves over them you see it move a little higher due to the capacity sensor. I was watching the videos on half speed so I could see what it was doing better. I think you would be fine with either controller. I will try to do a demo like this for you to see once I get up and running.

[@nerdulator5000]

@@diyfiberlaser That would be great. Id love to see a demo on this. Appreciate it. Looking forward to your next video!

[@Iamtherodlight1453.]

Are you in the US or Europe? Thank you.

[@cricketgreen6284]

Total cost? (All in)

[@diyfiberlaser]

I’m still working on putting together the final BOM…but under $11k

[@emreturhan2991]

Hello, is there any affordable CNC control card you can recommend for lathe and milling machines? I follow from Turkey, sorry for google translate

[@diyfiberlaser]

There are many cheap controllers available, but I've not used them...I've been using the Masso on my machines.

[@seimela]

There are many of them my freind... cheaper than Masso and work better than Masso go China

[@3dpartner]

where to get the remote ?

[@diyfiberlaser]

It came with the controller
