I really like your videos and I have learned quite a bit from you. I am new in the CNC world but I do have experience with the manual machines. I do have eye for spotting issues. There is no shame in getting inspired by existing solutions. Machines that use fixed Z axis and bed that moves in X and Y axis have huge Pilar holding the Z axis. Bridge structure can't make it in this case while Z axis can't be supported good enough. They mostly use counterweight on chains to balance the weight of the Z gantry. Now steel used for bolts has way higher tensile strength and even hardness than mild steel stock. I bet if you have used bar of the mild steel your machine would perform way better. Love the solution for gathering the chips. Definitely good enough for size of the jobs one does on small machine. Most probably I am going to design something similar for my machine. Thanks for that one. Looking forward for the next design.
You could not have picked a worse case for your tests. Cutting the end of a bolt like that is like using a very long end mill in effect as you have deflection in the cutter one way and deflection in the bolt the other way so its not surprising you get some vibration, when you try it on a piece of flat steel things should be much better. You have done very well with the build, looking forward to watching some projects on the machine. When working out the stepover you need to calculate the chip load, there are many calculators online rather than guessing, sometimes its better to go faster with less stepover to keep the chip load within spec, most cutters will give you the best chip load on the box and so you need to set your motor speed, travel speed and stepover to get closest to the cutter spec. I think fusion is very aggressive in its calculations and thinks everyone is using a 30hp mori-seki or similar machine.
Fantastic! I think the bolt you are working with is made using a rolling process, which puts a whole lot of stresses into it. This makes them horrible to machine by any method. I agree completely with the conclusion you have reached regarding the rigidity, but if you can get your hands on some steel sold as "Free Machining", I think even this machine would have produced better results. It is a sad fact that the more rigid and solid the machine is, the better your chances of success with steel etc. You finally end up with something that does a great job, but you could never move it! Looking forward to more adventures! Thank you.
Thanks for the great video! We need more DIY videos like yours. I wish you would do a video using LinuxCNC. It's free and I quit using Windows years ago. Now with Windows11 you don't own your OS! Time to leave your comfort zone and help out your struggling viewers a little more! I have the links to LinuxCNC and Mesa control boards if you would ask. I will not support Mack3 and Windows! Thank you for your great effort.
@@minhsmancave9448 If your not up to the challenge, I understand because it's not easy but meany of your viewer are giving up on windows because it's not safe to connect to the internet with older unpatched versions. In addition Fusion 360 and SolidWorks are not very piratical because of the money games they are playing There is a recession on the way and most of your viewers have to make a choice of buying gas to go to work to feed the family and spend hard earned money for their hobby. Not all if us can bring home a copy from work. What's the sense of an inexpensive CNC machine of you have to pay too much money in supporting programs just to use it? Not ideal for your viewer base of DYIers. BTW, why are you using a hardened bolt to test steel cutting? That's like using an aircraft carrier just to go fishing! Remember: we are all in this together!
@@frodobaggins169 I am sticking with a heavily patched Windows 10 forever. I miss Windows 7, but I can tell you I have no love for Linux in 2022. In 1998-2005 I loved Linux, but so much just doesn't work or works half ass. No, not the issue with Linux it is the issue with say Nvidia. Using half a year, or more, behind the current version of their drivers and programs like MSI Afterburner was crap in 2020. I just didn't care for the four distros I tried in 2020 as they try to mimic Windows without actually the abilities of Windows. Again, that is the problem with Microsoft telling the companies NOT to support them. They did it back when I used to work with them in 2001 so I know they still do. As to the impending global depression I agree. The problem is you act as if this guy needs to suddenly jump off of what he prefers to satisfy the people who left Windows. It isn't his job to do that. I agree Autodesk sucks since the 1990s so eff them. Dasssult has always been arrogant, and it took them forever to even have their stripped down version WHICH, by the way, I love Solidworks but their inbuilt CAM solution sucks ass juice. HSMWorks is miles ahead, but costs. It is the exact same engine using the exact same numbers, etc... as Fusion as they are the same. Fact is HSMWorks is offered if you pay for Fusion sub. I really do not know of a viable solution, even on Windows, for the CAD part outside those two. There are choices, but they are nowhere near as good. As to the CAM part I never found anything that I liked, and I never did conquer HSMWorks (got closer than the built in SW one though). What we need is a 3d slicer (like we use for 3d printing) for simple CAM of some sort as I know it could be done. Why it never has been I just do not know being 2022. We already do so much to get the CAM working filling in the variables there is just no excuse that I can think of.
@@thebeststooge I appears you have a lot experience and I admire that! If your looking for cutting edge with Linux, It's not going to happen and never will. I've been using Debian for 10 years and it works for what I need. Admittedly my install has gotten "long in the tooth" because Cura 5 will not work and I can't compile from source because my version of "Cmake" is not new enough. So I'll have to update to the new Debian but I don't do much 3D printing any more I don't need a cutting edge slicer. I'm retired and with machine shop experience but little CNC so I'm learning from were ever I can. My CNC machine is a Genmitsu 3018-PROVer that's made for "Not Metal" With everything CNC the software is a money game that I will not play! I'm finding out that CNC is for people with little or no machine shop experience. Some of the best machinists I've seen on UA-cam are old school from Europe and the one that I really admire is Cà Lim from Vietnam! His love to create out of metal pops out from the screen!
I'm not sure if the bolt I used was hardened. I thought it was mild steel. And I agree with you that CNC is for people with not much skill and experience with machine shop. I myself is one. I only started making things in my garage 5 years ago after working with surgical scissors and knifes in a lab. And that's why I love CNC technology so much to make up for my lacks of skills. Trying to cut steel is a huge step up for me since I've never even imagined doing that till recently.
I'm but not in a few months. I'm currently working on other projects that are more business oriented. Will get back to the cnc machines in a few months
Yes, I'll try to install the coolant pump for flood cooling. I'm just not very happy with the rigidity of the frame right now. I had an idea to make better one and will try to build it.
@@minhsmancave9448 That was a compliment as no one should care what something looks like only if it performs. Remember this old saying that the material you wish to work on the machine needs to use that material, or better. A lot of the issues is the aluminium as 1/6 the depth and steel is just as strong. That is the hard part getting those things made out of steel so the machine becomes rigid enough to work on steel.
Getting a Genmitsu 4030 this week. Curios how many things I will replace over the coming years :-) Next investment will be a compressor with 60db instead of 95db and a cooling hoe. Can’t run the compressor in my apartment….
Slowly, you will replace everything, lol. It usually fine at first but at some points, you will want to do more and need to upgrade, then upgrade of the upgrades.
Hello my friend, I would need your help once again, my little motor of the X axis of my cnc produces a squeak and sometimes stops for a few seconds when I start it and this noise continues during the cutting. I bought a new stepper motor, but it's still the same noise. Do you have any idea where the problem comes from?
@@minhsmancave9448 Thank you very much for your quick response, indeed I exchanged the motor driver, the stops have decreased a lot! but sometimes there are still some noise and stops arround 13 times for all project of 10 minutes cutting on the axis X !
Hi my friend, I have new question, I want explore cnc lathe machine, do you have idea about programme what we should use? Could you make for us some tutoriel? Thanks
Haha designing your parts to be square so you can avoid contour passes is the strategy of kings. It is second only to designing your parts to be square and the dimensions of standard sizes of aluminum stock straight from the manufacturer. 😉
I wish that I have more means to actually make my designs a product to sell. I only build one for now as hobbyist. But this design need some improvements and I will to do that soon
@@Joseph-hp7gt It really is as I watched him take this lowly turd of a machine that was barely able to do wood to what it is now. A Frankenstein's machine with him being the creator of it (Dr. Frankenstein). He truly has come a long way.
You're doing a GREAT job for the community sharing your journey... Thank you!
I love the way you build on a budget then use the machine you build to upgrade itself. Very clever!

I thought the counterweight was brilliant! Keep up the good work, and your Fusion360 explanations are appreciated too.
Amazing work! Really appreciate the work you put out!

This machine should really be able to hog out some aluminum though! I'd say you could do 1 to 1.5mm step-down on aluminum. Have you tried yet?

The choice of controller and OS really depends on user preferences. I don't think it will affect the performance of the machine much.
