You can say using old weights is a no no all you want, the way that slab cleaned up was really surprising.. Awesome work! I'm going to have to keep a eye out for all the folks that give them away for now on.
G'day Vince. That was an excellent idea to use that dumbbell weight as a backing plate. I also really liked how you used the end mill to machine the chuck step and you obtained excellent concentricity with that. Great 4th axis build Vince. Keep up the good work. Aaron.
I don't know if you got your issue sorted out with z going to home position. If you didn't, try this. In fusion 360 CAM, in the post processer part there is a box for "safe retract" make sure this this is not set to G28 and to clearance height. Hope this helps.
I have the same chuck on my lathe. For better runout, machine the indexing part of the backplate a little undersized and clamp a endmill into the chuck. Mark the pinion you used to tighten it. Then loosen the bolts and just snug them up again. Bump the chuld around until a dti reads as little runout as possible on the endmill. Tighten the bolts and only use the marked pinion to tighten the chuck
Merci a vous !!!👍🏼 Et surtout pour le liens avec Aliexpress 👍🏼👍🏼 Je voulais en faire un pour la mienne de machine l'idée est vraiment excellente Grand merci et au prochaine vidéo 🤓
Fusion 360 automatically homes the Z-axis anytime you do an A or B axis move. You can edit the post processor to get rid of this, but if your machine rapids are pretty fast, you may as well just leave it. It will save your bacon at some point lol.

Very nice build. Have you considered making the fusion files available for other DIY type builds? I'd love to build something like this, but it seems silly to re-do all of your work when it's probably sitting on your computer already done.
In mastercam you have to edit your post for c axis unwind - older 4th axis with wires are limited in rotations before it has to unwind, its done by default for compatability. Also maybe encoder limitation as well.
good afternoon friend was great the service and the perfect finish this congratulations, ok att sader. I'm just going to give a constructive hint of the whole service. The flange usually has to have about 3 to 5 cents more in the case of this 160mm plate, it would have to be about 130.05mm in order to enter the pressure and not have any slack because that could be it that gave that minimal difference, more coming back to the video it was perfect man show of ball
Nobody mentions how to home the rotary axis especially when you use tombstone or sqaure stock. Do people just use dial indicator to square a flat surface? I see no proximity sensor.
Hi , im a fabricator and machinist, but i dont have any idea about electricity and electronics. Where can i learn about this stuf, to make things like this. What should i start looking for . Great videos by the way.
Im probably way late to respond, but the Z-home should be adjustable in the Retract Height.. Or, just look in the g-code and modify it. 👍🏽 Awesome work!
I thought I was the only one who used weights for cast iron! Great job by the way. I am doing a similar project for my college machine shop. Do you think I could get one of these to work with a HAAS TM-1 ?
The TM-1 has to be “4th axis ready”. That means a 4th driver board is installed in the machine. Open the control cabinet and see if the card is there. It is an extra cost option and many school and industrial mills do NOT have it. In the video only 3 axes are being demonstrated. X, Y, and Rotary are simultaneously moving. The Z axis (i.e. 4th axis) is stationary! Quite possibly he has the same issue by not having a 4th axis enabled either in hardware, software or both. He later commented (thank you) that it is NOT a harmonic drive but rather, a planetary gear set. Without the zero backlash of a harmonic gear the device has a continual backlash problem and is not suitable for hands-free CNC operation. Apologies for being a very late post. Offered here only to help others in the future.
Better finish and tool life if you climb mill. Not sure why you use so many microsteps when you have native 10,000 pulses per rev already? Works very nicely although you are taking "proper" cuts with that machine! The 50:1 ratio is fixed by the gears, so nothing to check / calibrate. I'm also using a harmonic drive - they are beautiful things! Nice work!
It is 99,99% post processor related "issue". You can use VSCode with f360 plugin to actually see where this exact homing-gcode line is generated inside you post. Also just be aware that 4th axis features in f360 are quite limited.
Hi Vince, my name is Valmir, could you answer me if you can provide me with the design of the parts for CNC assembly, as I'm waiting for your reply that I sent earlier in the cnc milling machine assembly video
Nice Video's My suggestion is to learn Gcode....with it, you will be able to tap with your machine and control the z going home every time. with sub programming or user macro, you can do math/ create your own cycles. I assume you have an encoder on your Z axis.... Old CNC programmer 40 + years Joe
It only knows where work offsets are, in order to prevent from running to it you have to make sure you have clearance from it in your program. Like proper tool length and clearance
Hello awesome build, regarding Z home after each pocket, if you did not find solution check in your G-Code if you have G28 command, if you have it, delete complete G28 lines where G28 is and make a test without tools and stock. Br.
man i like youre stuff , but please ! use adaptive clearing. Youre endmills will last longer and even under heavy axial engagemant you won`t have any chatter. I guess youre machine is easy capabil of handeling loades like 0.2mm per tooth at 6000 rpm and an radial engagement of 0.4 to 0.8 mm.
Looks like you have plenty of z travel. Too bad you didn't make the 4th axis 2" taller allowing a larger diameter to be cut. A large bearing inset between the aluminum frame and cast-iron back plate would eliminate most of the vibration. Welded steel frame would have been better too. But great job! Wish I had your setup.

incredible .. nice work as always
I would like to know where people are getting the metal to build stuff. In Texas it would cost more to buy the metal than to buy a 4th axis.

Thank you. I guess if stepper drive is compatible with TM-1 it should work
I think they sell with their new machines an "optional provision for a 3rd party 4th axis"--maybe check and see if it has that?
I own 2 VF4s if you have the 3rd party option, as another comments says, it should be good, I would personally buy a Haas rotary though.
@@BebenX thanks for the answers, I will check if the college opens this fall

It's been a few years now, how did this build work out?

Thx for the comment. I will try without micro stepping
What type of gearbox did you use ?
How much did you end up spending on parts?
hi how many kilowatts is the spindle and where to buy
Im a little late to the Party, but are you not worried about the imbalance caused by the old weight? The number 10 on the weight is not symetrical
at 0:03,i would like to know what type of drill bit it is and how fast it spins.
its carbide end mill spinning at 10000 rpm

Man! You are amazing!
Thanks!
What post processor are you using? Did you get warning: Work offset has not been specified. Using G54 as WCS.
in Fusion360 NC program?
In fusion NC. I did not get any warning
did you make this on work day or on holiday? i think it need time to design first
does the software know where the chuck jaws are, and if not how do you prevent the spindle running into them?
It only knows where work offsets are, in order to prevent from running to it you have to make sure you have clearance from it in your program. Like proper tool length and clearance
12:20 what speed of spindle you use at that time?
10000 rpm
Can I get the cushion file for how you did the g-code for this?
Parabéns ! Perfeito.
where can we buy the plans
Sir, what CAM are you using ?

Great job sir
What did you set in mach3 pulse per mm
Or pulse per digress
Based on my gear box ratio and my controllers it ended up 55.555

adjust the heights tab in fusion
Is there any balance issues with backplate?
Not in this kind of rpms

are these drivers good?
no issues with them?
So far so good. No issues

@@advanceair I mean CNC os system
How did you attach the chuck to the backplate?
It has 3 bolts from behind
You could access the bolts to mount the backplate to the gearbox through the center of the chuck?
It doesn’t look possible.
