    Hello Travis!!! I came from the last video of the serie, just to thank you your effort by sharing so much amazing videos. Right now I'm building my own plasma CNC machine, but I would love to make a fiber optic CNC in the future. I would love to contribute in the design enhancement (I'm not saying it is a bad design of course). If you ask to me what I would change about this machine, my answer will be, making all the panels with sheet metal bend. Again, thank you for such an amazing channel and effort.

    Really excited to see how it goes with the cheaper laser source and controller. I built my CNC Plasma table with the intention of eventually converting it to being a fiber laser machine. Looking at prices of the components mentioned, you could get the fiber laser components for close to the same price as a higher end plasma cutter. Tariffs add to it, but you are trading that for a higher quality cut in my opinion.

    one potential problem could be the carrier drag chainon the left, limiting the travel of the y axis when the gantry is at the front. from my experience it is worth the extra time animating the chain to know the runout and the exact number of chain segments.

      I agree with this comment, at one end is no problem, but at the other end you wont have enough room for a "loop" because it will hit the vertical post. If you don't have a loop in the carrier then the cables will have to make a sharp bend. Are you familiar with the lumenPNP from opulo? Look how they mount the carrier, I wonder if that would work..?

    Hi Colleague!
    I would make the base of the machine welded if you want to increase the cutting speed. The head of a fiber laser is very heavy and will cause inertia at the point of sudden stop and acceleration. this inertia must be dampened by the frame, otherwise vibration will not give you a high quality cut. now you have very short stiffeners due to the small corners for the aluminum profile. if it is not possible to weld the frame, then cut out flat triangular stiffeners from a sheet with a thickness of at least 3-4 mm and fix the frame parts with them to a bolted connection.
    also make sure that the sparks will not fly on the belt, otherwise it will sooner or later become unusable. 5m is a good belt, but it can also deteriorate from sparks.

    • @diyfiberlaser
      @diyfiberlaser  7 หลายเดือนก่อน +1

      Thanks for your feedback. I want to use aluminum extrusion to make it accessible to non-welders, but I like the idea of triangle braces...we could use the machine to cut them out. Sparks on the belt is a concern of mine also, we'll have to see...they may be high enough above the cut to avoid the sparks.

    • @Pyroprinter
      @Pyroprinter 7 หลายเดือนก่อน

      I have another idea for you. You can cut a square pipe on the first machine. Why don't you use this advantage when assembling the frame? An aluminum profile is needed when you need straightness. Where there are mechanical movements. At the same time, you use a fairly small aluminum profile. 20*20 and even 40*40 mm is a rather thin design. At the same time, the aluminum profile is decent. Plus corners and stuff. You can assemble the main frame from a square or rectangular metal pipe with a cross section of at least 40*40mm or 40*60 mm. You just cut the pipe to size on a laser, make mounting holes (if you are afraid that you will not get into the holes with your teeth, then you can make them oval) and then assemble the entire structure. Bolts can be taken at least 6mm, preferably 8mm. This is much better than the 5mm bolts from the corners of the aluminum profile.
      This way you can add diagonal joints that will increase the strength of your structure.
      I have a workshop and I have a laser fiber machine with a pipe cutter. He does very cool things.

    • @Pyroprinter
      @Pyroprinter 7 หลายเดือนก่อน

      Another thought is, of course, the question of the size of the working field of the machine. I understand that you have a small workshop and just don't have enough space to place a large machine. Trust my experience, it is very convenient to put a whole sheet of metal at once, which does not need to be sawed beforehand. And on this sheet you will get larger parts and you will save on metal waste. Because the cutting will be more economical. To do this, it is convenient to use the nesting program.
      It's just that the main part of the cost of your project is the laser source itself, the head, the chiller, the controller, the motors, the drivers, etc. The mechanical part here does not take up most of the cost. That is, if you had a place where to assemble a large machine on a sheet of metal (we have a local standard of 1.25*2.5m sheets), then the cost of your machine would not be much more expensive.

    • @Pyroprinter
      @Pyroprinter 7 หลายเดือนก่อน

      ​@@diyfiberlaserI don't know if you use oxygen or air as a gas. We have a 16 bar screw compressor. But it's expensive. It costs about 70% of the cost of your project. I can tell you how a local DIY craftsman solved this issue on his fiber machine. He bought an 8 bar screw compressor, put a booster on it that compresses the air by an additional 2 times (consumption also increases by 2 times, so a productive compressor is needed). For air treatment, he assembled a large cleaning filter. I just welded a filter out of a thick pipe (about 1.5 m long and 120-150 mm in diameter) and filled it with something like cat litter and something else. This is necessary for oil and moisture removal. He generally made a chiller out of a container with water and an air conditioner of 9000 btu (it seems to me that this is not enough, but you have a 1 kW source - it should be enough). It turned out to be cheap.
      Although I wouldn't do that to myself. But if there is no money, but you really want a machine, then this may be justified for him.
      If there is a desire to communicate, I can use WhatsApp to show by video how our work is organized in the workshop. We are constantly in the process of modernizing production.

    Maybe you've thought of this: if you have a bottom hinged door running the width of the machine across the front middle-third section where the parts drop into would make part retrieval much easier [without having to remove spars from the material support bed] and would make cleaning that section with a brush/vacuum a simple process.
    Where fume extraction is concerned such a door could be easily sealed using off the shelf commonly available window draft sealer strips or butile strips on the back of the door in order to stop fumes escaping out of the front.

    Since speed is one of the main goals, any reason you're not going for a CoreXY motion system? Even with a heavy head, it still moves the X-servo from the gantry to the frame, and servos aren't that light either. While it slightly complicates belt routing and needs longer belts in total, unless absurd accelerations are needed (above 10k mm/s² or so), the additional length shouldn't be a limiting factor (assuming quality belts like Gates or equivalent).

    • @diyfiberlaser

      31 mm diameter pulleys
      (100 mm circumference)

      With 5:1 reducers = max 600 rpm
      600 x 100 / 60 sec = 1000 mm/sec

      The motors are 400W 1.27Nm…one for X and dual for Y. I can figure out a close estimate of the weight of the components.

      @stefankrimbacher7917 7 หลายเดือนก่อน +1

      ​@@diyfiberlaser Theoretically acceleration without friction a = power /(mass x velocity).
      With friction you have accelation a= ((power /velocity) - Frictionforce) * (1 / mass)
      So these aren`t both useful equations for sure on one hand, because all influences of inertia and friction aren`t calculable in detail.
      On the other hand the controller needs a useful value for the acceleration to avoid motion problems.
      Usually servo motor has nearly constant torque, so
      power P increases linear with increasing RPM.
      In this case: 400W at 3000rpm and 200W at 1500rpm
      Example: mass m=10kg, P=200W (1500rpm), v=0.5 m/s, no friction gives:
      a=200/(10 *0.5)=40 m/s^2= 4G.
      Most important is the tuning of all servo motors under real conditions to achieve good mixture
      between speed and accuracy.
      In my opinion two of the best videos on youtube due to tuning are
      from JBWorxStudio (nice German guy):
      Part 1: th-cam.com/video/_9Q-VFesnA0/w-d-xo.html
      Part 2: th-cam.com/video/jvbw_PMOs-s/w-d-xo.html

The 15mm GT5 belt has a working tensile strength of 444N...I'm not even sure how to start calculating at which point it will start to get springy...I need to find an online course I can take to learn this stuff!

      @@diyfiberlaser the limiting factor with the belts will be the stiffness not the breaking strength and that is harder to decifer with a catalog because your whole system will contribute. Think about using as wide of a belt as you can. Also upsizing the motors is not trivial. 5 times more torque will be a lot of mass. I have used a few different gearboxes for simracing projects from alibaba and lichuan had better quality then others. Consider helical planetary for reduced noise and backlash.

    Would be nice if you released all the files for free but then get the money by cutting and selling parts for the machine.
    But at the same time it's all 20 series profiles so people should be able to replicate the design fairly easily based on the video and the spec.
    Also to join profiles I would suggest using the button screw approach like they use on the voron 3D printers instead of the 90* brackets, this way you will save some money on the hardware, it will be easier to assemble and most importantly will be much more rigid.

      I thought about that, but I don't really want to do production work...I have to much creative energy trying to get out : ) Also, there will already be a way to easily order all the custom aluminum parts...I'll be mentioning it next video. Thanks for the suggestion... I've seen those connectors, but never tried them. I've already purchased the hardware for this project, but maybe I'll try using them on the next one.

      @@Arek_R. Oh I see! I found it this time...last time google showed me something similar, but there was an insert also. You could use this method for some connections. A lot of the extrusions butt up to a 40mm one, so you'd need longer screws. There are roughly 150 corner brackets used in the design...I don't know that I'd want to drill and tap that many holes if I could avoid it : )

      @@diyfiberlaser Trust me, dealing with 1 bracket, two screws and two t-nuts is even more work, it's very fiddly.
      If you make some drill setup it will be quick and easy to drill, same with tapping if you get a spiral tap and just quickly drive it in (don't need to do the whole in and out dance like with a generic tap).
      I see on the front you have 2020 profile butt up against 2040 profiles, not sure but I think you could still use this attachment type with it, first you screw 2020 and then there should be enough space around either side of 2020 to reach 2040 screws.
      Now that you told me it's 150 of them, isn't that like $300-500 of hardware?

      @@Arek_R. The corner brackets are fiddly! You're right, if I made some jigs the process might not be too bad. I actually have an electric tapping arm on the way, but it's probably on a container ship somewhere and I don't think it will arrive in time for this project. It is about $150 of hardware.
