I love you so much for making this video. You shattered the myth/mystery surrounding the setup and use of the cnc rotary 4th axis. I have a 3 axis cnc machine running on the Mach 3 software. I've always wanted to set up a rotary axis but without any clue. Great instructional video. One of the best I've seen.

As many others have said, thanks for doing this video. I happen to have the same machine you have, and I have most of the same software. I purchased an extra stepper motor controller from the CNC Routerparts factory in anticipation of some day getting a rotary 4th axis. This video will help get me going. Thanks again.

Excellent video!!! This is how videos should be done - the full picture of what to do and what you need. Start to finish! Thanks!

This looks like exactly what I have been looking for, for over a week. I don't know why it didn't come up in my searches. Thank you for doing a detailed tutorial on this.

I just ordered a CNC 4 axis mashine and saved your video in my library. Hope you and your family is doing ok during this trying times. Will love to follow your videos, for a " first" time you did an amazing job. Thank you for explaining everything so clearly.

great video, you have a clear way of explaining things and the detail is appreciated

Excellent video. Thanks for putting all the information together in one video. Must have took a lot of time and effort. Thank you.

Thanks for a great video. I have looked through dozens of mach3 tutorials and his is the first one I have found that explains 4th Axis so well. Great job

all i can say is thanks so much i have wanted to do this for so long and now i ordered it i run with the same cnc thanks for making it easy

This is awesome! Thanks for taking the time to make this video, and please keep up the great work!! YOU ROCK!!! 👏👏👏

Thank you. I'm going to try this as soon as possible. You're the only one on youtube with this much detail and for this machine.

Thank you bro.. I have been tinkering with this for yrs.. And finally I think I understand.. Been doing trial and error.

Thank you for sharing. I learned a lot. I already have a CNC router but I don't have a 4th axis. I think I will be buying one soon. this is good info form me. Like you said, there was no one website that explains from start to finish, you have to find each sections. You explained a lot of it. Thank you,

Hi Mark, I built my CNC router about four or five years back and purchased the bits for the fourth axis about a year ago, finally got around to fitting it up to my machine now I'm retired. Your video is very helpful on the setup in Mach3 which was what I needed. I recommend that anyone already familiar with Mach3 and wanting to setup a fourth rotary axis to use the link to Marks website where you'll find a text set of instructions that makes it really easy and quick to setup. One other note that may be of help to others is if you have a machine with four independent stepper drivers to leave all three main X,Y and Z axis' active, very handy when setting up material in the A axis. Cheers Mate, great work, I'll be looking at more of your stuff.

Thank you for taking the time to do this video. It has helped me very much. I purchased a CNC Router Parts machine with all the drivers and cables for a rotary axis. Thanks to your video I now have the courage to make it work. Great job. I would change anything in the video. The occasional funny mistake and comments helped to make you a real person....like me.

Hello Before anything, I saw your video on KZfaq too late. Your description was complete. Thank you for the time you have spent.

Nice haircut. Wow that was a surprise! Thanks for sharing this complete video. I have a 4th axis and not set up yet. This will definitely help me.

Excellent video on testing your rotary setup for alignment and accuracy. Very useful knowledge.

Very impressed with the amount of information you provided. This will be of. Great value to me. I’m just starting the 4th Axis carvings on my CNC. Thanks,

KZfaq suggested vids never fails. I'm using a different controller, but from my search i've noticed that In MACH3, there should be a setting 'use radius for feedrate' which compensates for the degree/min vs inches/min. From my best of understanding it compensates based on the Z offset from the center (it interpolates the F for the A-axis from the distance for the Z from the center of the workpiece) with this setting it's mandatory to have the Z0 at the center of the cilinder. It should be a job for a postprocessor IMO, the postprocessor knows what Z height is expected and can easily add another F value in front of the A movement. Another viable option would be to use G93 instead of G94. The G93 is by default supported by a Fusion360 postprocessor that's Fanuc compatible (Mach is also Fanuc compatible)

Thank you for your time. Extremely intersting. I hope I can follow your instructions. Thanks again.

The best detailed explanation of how to calculate and configure Mach 3 to cut rotary set up on the router. Thank you very much.

Liked and Subscribed... Worthy videos are hard to find. Glad I found this one. As a noob who has never had a chance to own equipment or software, and is doing everything academically, this is the next best thing to experiencing the savory moment when I will be able to experience this knowledge on-hand. - Thank you so much, good Sir!

Great Video! I wish more folks would take your approach, as it is very clear and very detailed!! Thanks for taking the time to produce this...

MUITO LEGAL! ESTOU ENTUSIASMADO EM FAZER ESSA ADAPTAÇÃO NA MINHA MINI CNC !!!

Very good explanation, thanks for the effort.

excelente video, muy claro e instructivo, sobre todo con Rhinocam

I have watched your video many times just for the math. I was able to get mine built and I did a video on the build and the programming and running the job. I wanted to thank you personally for haveing this video as it was my inspiration to do the 5th axis for years.

Thank you for this VERY well explained video on 4th axis. I just happen to have the EXACT cnc as you. I always wanted a 4th axis...so now I know how to install it. I also use Aspire for 3d work. Keep up the great work. Many will enjoy it.

Thanks for your video. Very informative.

Thank you very much explained in magnificence I have made a great effort

Thanks for the information.. very detailed video.

¡Excelente! Muchas gracias, hoy aprendí mucho gracias a ti.

Very good video, lots of really good information. Thank You

Finalmente una buona lezione Grazie menomale che ti sei deciso a fare il video lo sto guardando e ho messo in pausa per proseguire dopo. Ho voluto fermare il video in quanto volevo ringraziarti.Grazie continuo a guardare il video

Really appreciate your efforts and time. Great help..🤘🙏

Great video! I'll be setting up mine tomorrow!

This is a great information video I wanted to find.

Thanks a lot for the detailed video.

Great video! Thank you.

Well done sir very useful thanks, keep going

Worked perfectly thanks!

Thank you very much for this video please keep up the great work

Thank you , You have helped me , Great Video

Awesome! Thanks for sharing.

Good video. Good job. Love it!

Thanks, very good video. I learned a lot

Excellent, thanks for sharing.

I plan to install a fourth rotary axis in the future on my machine, so this video should be useful.

Thank you, Great Video

Great Video, Thanks a lot

Great work.

very educational, regards.

This was like attending a training course, than you so much.

great work

Thank you very much for this video, this has helped me a lot so far very well done. I just have one problem to solve i will appreciate it if you can help or if any one ells can. My rotary axis is working fine my problem is that the DRO on mach3 is not moving up or down if i turn the motor. What can be the problem, will check the comments. Thanks again.

Big up bro much love from

great video

When I bought my cnc set up some time ago, there was nothing on the internet/KZfaq to guide a newbie. So, thank you for the presence on KZfaq. Question: When installing the rotary hardware to be able to do work in the round/cylindrical... "Use a dedicated stepper motor driver...".. Does this mean a controller box just for the rotary/cylincrical carving. It has been really difficult to learn everything on my own and I am so grateful for your presentation on this subject. Right now there is a controller for the cnc machine to do surface work/flat work. Am working with a HighZ cnc and WinPCNC and Vectric.

Thanks for doing the video. Very helpful. What's next?

Fainstic vedio sir This is good for Marc3 persons. If possible plz make a video for Arduino uno, V3 Rotery axis... Cnc Thank u ...

thanks so much sir for amazing video. could you please, kindly help me ? i designed my machine setup as follows rotary axis and i attached to y axis pins in mach3 as i will not need y in rotation and i build spindle head on tilting axis and i attached that motor axis cable to a-axis pin in mach3 board so i will have total 4 axes " x-axis, rotation axis which is y in this case, z axis and a axis for tilting head" how can i program g code file using powermill or any program in my case???

Thanks you so much sir. Sir mai Ncstudio controller rotery operating karta hu hu rotery 1.5 round rotet hota hai. Sir kya problem ho sakati hai?

Absolutely excellent video, could you give more information on this exact rotary kit? Thanks and I think you have a great future doing videos.

I have DSP B58, what post processor is it support it for 4 axis ?

Hi sir Can you please help me how to write the G-code for 4 axis. I would like 4 axis and y axis turn same time but different feed rate. Thank you very much for your help!

You are a great instructor. Do you mind to share the series of your cnc router plz

Thank you

hobby user who want only sometime use 4th axis can build own 4 axis parts easy to wood, spindle need some bearing and belt bulley only whit new stepper motor, and pirch plywood can made bearing block box and tailstock easy. whit cnc have easy cut all parts.

Great Job Explaining all the setting, you pulled me out of a hole with the soft limits.. Thanks Sooo Much...

can you help in making my router please ?

Don't know if you can help me ,but i am trying to hook up a rotary to my Gatton cnc . My rotary is a 1-2.25 rotation and the driver is set to 8 micro streps at16000 pulses/revs it is a stepperonline driver DM542T version2.3 and I am running Mach 3. Any help with the settings would be greatly appreciated. Thank you

Thankyou.

Hello sir, Can I upgrade my 3 axis hybrid servo Chinese cnc router with stepper rotary axis?

I've watched the video a coupe of times while doing other things. Haven't had time to actually do it yet. But I did want to comment about a couple of your comments in the video. Your video is good and I'm sure haters will say what they say, it's your first video, shouldn't care too much. But the audio could be the same for you if you use the same mic every time. I haven't uploaded anything with a voice over, good on you for doing it. I hate hearing myself, outside of my head at least. But I do use microphones for what I record and you could either post process and align the audio, since you're using premier this is possible almost automatically. I use a zoom h5n with the built in microphones and adding external through the inputs available. But they also have the zoom h1, and it is more affordable while still having great audio. You could either feed the output into the camera, or wear the recorder with a lapel mic. Or wireless lapel connected to the input of the audio input. Any way you do it, you might want to try and capture with the same device each time. Otherwise noise is picked up and even if clean, will be different in each setup. This and several other things prevent me from being able to create videos in a timely manner. I just wish I could draw a basic flow chart for what I want to do and be able to drop all my files in one place, then have the computer step through the flow chart while using my files to create a video automatically based off of my editing style. AI will do this at some point, but wishing that could be the end of humanity. So I think I'll suffer until then.

Dear sir, I am really grateful to you for your awesome tutorial. Dear respected sir, I am facing some problem about tool change. Sometimes, I need to use 3 tools in a design. But when first tool works finished, I need to use 2nd tool but Z and Y level change. Please could you help me about that issue? Please

wow thank youso much

Hi there. I was wondering if you would be willing to help me with a couple of numbers. I have the rough idea of what your talking about but my brain freezes up when I try to make the rotary axis work. what would work best for you? thanks in advance. my cnc is the avid cnc 48 by 48 thanks steve

The easiest way would be: Use 1 profile and add a switch "4 pole 2 throw toggle"(cheap) it has 12 pins. 4 center pins goes to the driver. 4 outer (each motor) pins to the motors, calibrate for rotary axis only... calibration don't really matter, axis Y (the table) is only needs to move over the rotary. then flip the switch. Add a plug to the rotary axis, you can unplug it & put it away when not being used

True,.... most Gantry machines based on 3 axes are not built to make cylindrical objects. Most software works more like 2.5 axis ... VERY MUCH LIKE A PRINTER OR SCANNER. THE LAYER OF CUT IS FINITE AND SET IN X-Y .... Z is the cut, paint, etch, weld.... a single plane. With a true 4axis controller this is not a limitation... where R is a diameter of a plane of cuts of Z .... including the perfect positioning for Z in arcseconds of accuracy.

Do you have a post processor that works with rhino cam and Mach 3 well? I have successfully modified the fusion 360 cncrp post processor to work better with Mach and 4th. Same for aspire. However, rhino send to have what's missing from either. Fusion is great for design and accurate cuts, but it's currently not capable of the easy 3d toolpaths that aspire produces. Aspire will easily produce wrapped 3d toolpaths, but continuous 4th is a pain to work through. It is possible but requires creating multiple files to do what should be 4 sided or at least movements in the y axis as to cut some of the models without days of setup. Looking into rhino because it send it's capable of what I need. Don't want to purchase if it's going to be months before I can actually use it. Thanks for the info on the video again, it was much help. If you want, I can send you a script that some of us in the cncrp forum came up with for zeroing the a axis using 2 dowels. One in the spindle and one in the chuck. Grounding your touch plate to the setup and it will find the exact zero position for accurate setup.

Super !

Hey.. You are looking like Ragnar Lothbroke, Vikings character 😍❤

Can you turn? I mean that if you can make pieces as if it were a lathe, roughing of cylindrical materials; Does it reach speeds like a lathe? I want to make one but with a CNC router and mount the rotary lathe but be able to use it as a lathe. I hope you understand me and your machine and the work you do are excellent, regards.

Good DAY friends. I have problems whit the alineacion of side and side of the gantry. Work, assemble machines with the same structure, only they have a table between the rails. My problem has been to align the rails on each side, to ensure parallelism and perpendicularity, preventing the gantry from crossing and stopping. The rails are located at a distance of 3 meters from each other. Know some technical and effective alignment system. So far I do it empirically with a tensioned steel wire.

i just start make same 4th axis system, today has order all bearing block at lathe spindle and tailstock parts, my DIY linux cnc machine, yesteday make ready all spoilboard clamping system to table and now 4th axis must made. normal controller card have 4 or 5 axis connection, can use 4th axis need only wiring new axis to controller, my controller cost only 10$ and can add 5th axis. i use linuxcnc software easy add new axis.

I have the Exact setup from cncparts. The 33.33333 worked perfect but A axis moves so slow that my bits burn when wraping. I have maxed out velocity and acceleration in mach3 . Any ideas how to speed up A axis. Thanks and great video.

Hi where can i contact u?

Can You tell Us what the model of the unit that you have and who sells it

i see you are good

Material Diameter: 70 mm , Length : 145 mm , Step Motor : 1.8 Degrees , 4.9A ,15.87 W , 200 Step Reduction Gear : 140 revolution/min , [ 1/10 ] Please help me ? , I did as you showed but I could not reach the result..I should calculate StepsPer , Velocity , Accerlation .. When I write the values obtained as a result of the calculations we made with you, when I make the material take a full tour, it does not come back to the point where it started.

saludos,por favor cuanto cuesta esa máquina 🙏.

Hi again I need your help with some settings. Is there a way to contact you? Of course, if you have enough time for guidance, please write to me in the comments thank you Alireza

Are these strong enough to do aluminum?

Why would you touch off somewhere else, if you know machine coordinates? You could just use machine coordinates to set to center... or am i missing something?

hmmmm. the method of testing the diameter at 33:00 doesnt make sense to me. Even if the piece is mis-aligned aren;t those diameters of the cut going to be the same? The cuts just wont be perpendicular to the linear surface but the diameter should be the same. Am I missing something?

tja, gaat inderdaad altijd veel tijd in zitten daarom begin ik er niet aan. Wellicht maar een dergelijke ooit eens zelf met de 3d printer. Zodat ik hem op mijn cnc mill als ook laser kan gebruiken. En mach gebruik ik ook niet maar vaak is het idee voor alles het zelfde alleen instellingen kun je niet 1 op 1 nemen. moet ook nog een beetje DIY zijn heb.. su6

Hi

The model number you gave me was a laser module.....

Fantastic video, although my wife lost interest after a few minutes ;)
