Jay's beard has left the building. We'll miss him!
And the hair on the scalp. Welcome to the club Jay!
The more I see and learn about CNC the more I want to invest in one. Thanks for the video.
Good explanation and a cool project
Jay, that is so cool! You and Frank Howarth really are doing some interesting things with the CNC and the 4th Axis!
Great to see you again on the timeline 🎉❤
Once you get everything dialed in, I love to see you make a super intricate piece of furniture just on the cnc. Like a Queen Anne side table or something similar with intricate moldings. Would really upset the internet. 😂
I see the Bates family still regards Pluto as a planet :)
Pool cue mallet handles! And door pulls? Your woodworking possibilities are always increasing, and it's fun to watch. Thanks, Jay.
Very cool! Great video! Congrats on getting this set up!
Hi Jay, I have a 4x10 Avid Machine, I bought the Rotary with the machine. I had the rotary axis positioned the way you have with the tail stock on the X=0 side (until this week). There are some challenges with this. In Aspire you have to set the origin to the right side which is fine but the Y axis (A axis) is the wrong way round - everything is backwards! So if you want to put some text into the rotary job you have to mirror image it, if you want to put a spiral into a job, it comes out the wrong way round! I worked like this for a couple of years but decided to fix all of this by switching the rotary axis around to have the headstock on the x=0 side, like in the instructions. Of course the touch plate is now too far back and the Y limit is exceeded in the setup steps. Arrrghhh!!! So I'm going to have to switch everything back but wanted to rewatch your video first. So my question is why did you put your rotary axis in with the tailstock close to x=0 when you fitted this? The instructions have the rotary axis facing the opposite way to you (and mine originally). How did you know? And have you had any issues with this setup?
Great to see you so excited! 😁
Another excellent video Jay!
Jay as an old school life long woodturner I have been intrigued with the 4th axis CNC for a long time but as the saying goes "old too soon smart too late" I have reinvented myself through your eyes and really like what I see, God speed.
Pluto truther, heck yeah.
Jay, instead of bringing the router bit down on top of the piece, try offsetting the bit so it does a side cut. This is how a normal flush-trim bit would work and you will probably get a much smoother finish.
Very cool. Nice job
Thanks for sharing your journey! Sometimes with CNC the first time we do something you're hesitant and take tiny passes, I like that you get aggressive and see what the machine can do. Can't wait to see a full blown cue with inlays.
Just got my avid 4th axis recently and need to start tinkering like you did. Excited to see what cool ways you implement it into your work.
@jaybates "work smarter" I am with you: CNC it to 90% cause that is just higher grade milling. Then hand finish to 95 - 100% by hand if that is your thing.
Artistry is artistry whether with hand tools or designing a model for the CNC. Good job, Jay!😊
Jay I made Que sticks about 27 years ago and the way I got very smooth cuts was to use a three wing slot cutter along the side of the shaft or handle. I used a router on my lathe with a tracer attachment. Try it, works great.
Very cool. I need to get back to trying to figure out the little hobby CNC I bought.
Magnifique explications
J'adore ton travail et tes vidéos son ci explicites ❤
love fourth axis milling , brings a lot of new options to cnc routers , generally use s spiral finish cut with a ball end mill with 6-10% step over , this is one long spiral tool path from one side to the other , not steps in x axis like you was doing which leaves steps or machining marks also " depending on your software , I use deskproto " you can do automatic rotation cuts and this allows x y z moves along with a moves " fourth axis " often required for high detailed models , pipes etc , makes the fourth axis behave like an indexer , both true fourth axis and an indexer have limitations but luckily we can combine them for best of both worlds " assuming your machine doesn't drive the fourth axis with its y axis "
I see a curved claw and ball leg showing up soon. Good stuff Jay
love it. I have the Axiom AR8 and it offers the 4th axis . I think your prior CNC was an Axiom and if I recall Bent's wood working has it or had it . I wish there was more content geared for CNC . I see people hating on the CNC but that is kind of a shame. For many of us wood working is a hobby where we can relax and create things. Stress on the word create things. I appreciate hand tooling I find it fascinating to see things people have created using hand tools. I kind of wish that the ones who are passionate about using hand tools would just relax a bit. Like your video showed so clearly wood working skills are still needed to produce things via a CNC. that does't include the time spent learning how to make designs and develop sound tool paths so you don't kill your project piece or even your machine. I have only had my CNC for half a season of wood working so I am super green at it. The thing about the CNC is your imagination is hopped up on steroids. I do wish I had the ability to do a vertical hold for joinery.
So I have a question since you used to own an Axiom CNC were you able to configure any way to add vertical holding to do joinery with that particular machine.
Nice video once again. Not sure I’ll ever invest in a fourth axis but I do toy with the idea.
7:50 try a spiraling toolpath, wrapping it is just a line at an angle
Computer or not, it’s still art
I have got to get a CNC! I’ve been looking for a while I really like I can get a base Avid and upgrade as I learn and go.
Nice, Jay. It was interesting (I don't have a CNC) because you were experimenting, not doing an evaluation of a free tool.
Bill
I don't want to start a trend here but..... Epoxy river table legs? I can see those being diped into a "Mould" and then resmoothed on the lathe.
Hi hope you are doing well,
How do I set the Z-axis position?
Hello,when i use art cam. I don't know how to align my model on the y axis;I am trying to creat a bannister which has the X wrapped around Y but it seems that I can't align it right because after i click create rotary relief and having a look at it in the unwrapped mode it looks awful; can't even realise what I'm looking at; any help would be appreciated, thank you
Thanks for sharing...so I'm new to woodworking, would you mind telling me the name of the style of sanding block that looks like a half-rubber ball at time 12:57~1259 in your video. As well as if there's a recommended vender who carries it? Thx!
Next is the automatic tool changer 😁
The woodturner in me is very annoyed with this, but cool stuff man!
Great Jay! Yesterday I machined a semi sphere out of plywood with my fourth axis. Best thing: I write a one line G code for the actual cutting operation, instead of the 3000 lines V Carve was offering. Happy sunday! @tallerstolarka
maximazur: Can you share that one line of G-code?? Very interesting.
@@richardevans6891 First I start by gluing discs with different diameters instead of starting with a cylinder. Best way to avoid messing things up, is to generate a straight line in Vectric, starting at the origin position. Save that g code. Then edit it this way: search for a line with lots of G commands (G90 G20 G17etc) and change G17 (XY plane) with G18 (that's the XZ plane)
Then erase the G01 command (the straight line)
Generate a G03 with the amount of units you want to move in X and Z with a Radius and feed rate. The amount of rotational movement (A) will give you the resolution or overlapping, so you can edit that on the go in Mach3.
My example: a perfect 200mm diameter semi sphere. Starting at G00 X0 Z0 A0, I wrote this line:
G03 X100 Z-100 A29000 R100 F700
Start setting the Z height at a higher position, so you can move in the air and check the movements. Then lower Z and use it as rough pass until you clean enough material to run a finishing pass. Increasing A value will end up in better finish surface.
Good video, I have the 4th axis on my 5'x10' but been learning the sheet goods side more and haven't used, this is a great concept to try.
I installed my rotary on the front end where you have vertical, and honestly did not consider it would work on the back end as well. Curious though with both the vertical and the rotary, are you able to fit an 8 foot sheet still?
❤
Wooden lightsaber hilts...just sayin'.
Nicely done Jay. Pretty good for a first outing. Are you tempted to get an ATC for your machine?
👏👍💪🔥
It always sucks when an OOps bites you. Yours was .04?? maybe. Mine was 2.5 inches.
It really is a shame that vectric vcarve doesn't do 4 axis rotary carving. There isnt even a good way to do multisided (other than 2 sides) rotary indexing. I think they have 4 sided carving in cut3d but thats even more money for their software
a lot can be done with a bit of thinking. Rotary indexing can be done manually commanding X degrees and zeroing for every index. Using the A axis as if it was Y a wrapped toolpath can be done in normal 3D, "Y" coordinates is just in degrees
@fuzzy1dk yea, where i have trouble doing rotary indexing is accurately positioning and rotating the model in vcarve. It seems that if i want to do a four sided job i essentially need four vcarve files and the model importing process needs to be exact with each file. As i get more time with vcarve I'm learning the tricks, but it would still be nice if it could do 4 simultaneous axis's
