Hanoi Amator Project (HAP)
Hi,
This is my first post at Lathetrolls, after spending time Reading and learning, then try to do with what I already have, hope it works soon! Just show some pictures of my new project, just start! Pls give me comments and advices!

Re: Hanoi Amator Project (HAP)
Looks like a fun project.
One thing, I wouldn't use wood to carry the over head. The mechanical movement could cause movement overtime in the support.

Re: Hanoi Amator Project (HAP)
What's the pitch of the leadscrew?/Where can i buy one?

Re: Hanoi Amator Project (HAP)
Yes, I know its better if I use in metal, however it is more difficult to make now, I will rebuild in metal when I finish some other parts: head cut, speed control,..petermontg wrote:Looks like a fun project.

I'm wondering what should I choose the transducer: This one https://www.adafruit.com/product/1785 or https://www.adafruit.com/product/1784 or I DIY
pls give me advices, tk uuuuu!

Hi There,

The Sparkfun/Adafruit type transducers are not your only options. Have a look here for instance :- https://www.parts-express.com/cat/exciters-tactile-transducers/18 I've made an as yet "Untested" Cutterhead, my Soul Sculptor Head :- https://www.lathetrolls.com/viewtopic.php?f=15&t=6556 using these transducers, however Fred used some transducers of a similar type with great results (https://www.parts-express.com/dayton-audio-daex30hesf-4-high-efficiency-steered-flux-exciter-with-shielding-30mm-40w-4-oh--295-240) check this out where Fred shows the making of his Cutterhead too :- https://www.lathetrolls.com/viewtopic.php?f=22&t=6866Hanoi wrote:I'm wondering what should I choose the transducer: This one https://www.adafruit.com/product/1785 or https://www.adafruit.com/product/1784 or I DIY

Thank you Soulbear, this helps me alot!

And how many Watts the transducer should be, Soul?
Re: Hanoi Amator Project (HAP)
Soulbear! I've been waiting so long to hear your cutterhead!
I'm embossing with that parts express speaker, it does work fairly well, you can check out my thread here; https://www.lathetrolls.com/viewtopic.php?f=15&t=7323
I've got some of the small adafruit transducers on the way at the moment
Not sure if anyone else had the same issue (I'm a little rough..) but the coil did decouple from the cone on the parts express speaker, I managed to reattach it but had to forfeit the centering ring, so I get some wild resonant frequencies
What are the specs on the stepper motors? Better than nema17s?

Re: Hanoi Amator Project (HAP)
Hi jjwharris,
How is your project going? This is the spec of my stepper motor (28BYJ-48 12Vol), it is small and rather quiet.
Diameter: 28mm
Voltage: 12V
Stepping angle: 5.625 x 1/64
Reduction ratio: 1/64
5-wire 4-phase can use ordinary uln2003 chip driver,
Can also be connected to a 2-phase use can make supporting the development board
Use, direct plug, easy to use stepper motor used in the development board

Re: Hanoi Amator Project (HAP)
I'm pretty happy with it, looking at improving the turntable and reducing stepper noise, that's why I'm interested in that stepper motor you're using, maybe I'll get one and give it a go.

Re: Hanoi Amator Project (HAP)
Have you seen these stepper motor drivers?
https://www.youtube.com/watch?v=P3ebhi-vZRY
The silent step mode can lower torque, but, wow, that seems silent.

Re: Hanoi Amator Project (HAP)
I think noisy or silent is not depends on driver, it depends on how many step to make around, microstep... So it is motor and the way to write code for Arduino.jjwharris wrote:Have you seen these stepper motor drivers?

Re: Hanoi Amator Project (HAP)
https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC2130_datasheet.pdf
Page 49 of that PDF explains the silentchop mode, from my understanding it provides more of a PWM control which results in a smoother motor motion, but also lower torque. I imagine the issue would be if it miss-steps, from not enough torque mucking up your LPI.
On my setup I still get slight stepper noise despite isolating the stepper motor with a rubber belt and butanol and foam between components.

Re: Hanoi Amator Project (HAP)
I change the motor to 24v AC, 1RPM and plus some pulley, it is very smooth and silent. The speed now is 5mm/min (is the speed ok??)
I also change as clip
Cheers!

Looks great! What this thing that you touch with your finger at the end of the video is doing and how do you call it in english?
Thanks,

That is quiet!

Re: Hanoi Amator Project (HAP)
You have a pretty course pitch lead screw there. The pulley ratio you have might be in the ball park for lead in / lead out - hard to tell from the video. If you swap the pulleys, it will get you closer to a reasonable rotation for normal grooves but still looks to fast for that lead screw to me. Can you tell us the pitch of that lead screw, and the RPM of the motor (or did I miss that)?

Re: Hanoi Amator Project (HAP)
My motor is a gear motor, if connect directly to pitch screw I can not turn pitch screw to move back when finish cutting or I have to wait same time if change motor direction. So I add one more pulley to cut off manually.EpicenterBryan wrote:You have a pretty course pitch lead screw there.

The pitch screw is 2mm/round, motor is 1 RPM so I add Pulley to increase pitch screw speed to 2.5 RPM.
