Cool video Richard. I recently bought a cnc router myself. I’ve had a lot of fun with it so far. I’ve got a while before I get to your level but I’ll get there.
Very good video and end product, but how would you cut multiple to exact matching lengths? It seem one more toolpath with a flat bottom end mill cutting partway through at top and bottom (a little extra length on the stock may be needed) would give you spots to finish cutting and smoothing by hand and exact consistent lengths. Same way as typically done on a lathe.
The Rotary extension is now available for 11 credits per day on Fusion 360. Curious to know if you have tried it yet. I am trying to get similar workflow with Mach 4 and Avid CNC rotary axis, but so far have been unsuccessful.
There was a short period when the Fusion rotary CAM functionality was available to hobbyists, and I played around with it in simulation. Seemed to work fine, and it convinced me to try my hand at building a rotary axis. By the time I got it built, Fusion took the CAM rotary axis function away from hobbyists; that led me to Deskproto. Deskproto works pretty well especially given its reasonable cost for hobbyist use. I am surprised you are having trouble with rotary axis on Avid-Mach4- Fusion. My impression is Avid provides good customer service; have you reached out to them? I have no experience with Mach4. Good luck and thanks for watching.
@@richardevans6891 15:31, it is the "shin" area of the leg. It is exactly the area that is below z=0. It is looking sort of flat or at least not rounded like other parts. I have heard that that part is actually very very sensitive to correct zeroing of the bit and slight mistakes can lead to such problems, so I was just trying to make sure, if you also found that to be the reason.
@@pradeepdatta7577 I did not determine the exact cause of this defect. As you surmised, it is the area where machining below the axis of rotation is required. I am not sure if the problem was an error in my zeroing on the rotation axis, or if it is an issue in the tool path created by the Deskproto software. Around 13:22 you can see how awkward the tool path seems where the side of the tool (rather than just the tip) seems to do some cutting; and this side cutting action may be the source of the problem.
@@richardevans6891 Ah ok. I just remember it being mentioned some place, that that part is extremely sensitive to the tip being zeroed perfectly otherwise a flat area or a ridge can remain. It is truly an awkward area, but I think you did a pretty good compromise. Thumbs up for you!
Hello Zeerabox, the Roughing pass took 1 hour and 7 minutes and the Finishing pass took 1 hour and 20 minutes, for a total machining time of 2 hours and 27 minutes. Thanks for watching.
In my machine, when in "rotary axis mode", the Y axis is disabled so the Y axis cannot move at all. In the rotary MACH3 profile, the drive that would normally be used for the Y axis is reassigned to the rotary A axis. Thanks for watching. Thanks for watching.

I love your product and I'm interested in one

Happy with the repeatability of the harmonic drive rotary axis?
what's the cost to buy one if I interested in it

Can you please guide me which software is using to make this type of program
Very yous full for me sir thank you so much 🙏
Great information, thanks!
The slight flat part in the area under zero, any idea why that happened?
Sorry, I am not sure what area you are asking about. Can you give a time reference on the video where this area shows up?

My machine's A axis is bad. Please let me know the A axis parameters
What's the time frame for the whole project please?

I use Fusion 360 for both design and tool paths. It is available from Autodesk for personal-use-only at no cost.
amazing
Could i have the gcode please" or the model" thanks
does your y across axis move at all thanks

@@richardevans6891 Did you give the machine a line of cocaine before starting?
hi Richard have you got an email address . as i need some advice for my cnc rotary carving machine
Hello Parmoor gunstocks, you can email me at: woodworker5@comcast.net
For those who do not know English, there is too much talk.
Hey, you were warned at 0:20. Sorry.
@@richardevans6891 OK, sory.
