Does anyone have any idea how Roland make their impact heads?
https://www.youtube.com/watch?v=zvXmtWM5ZCM

They work extremely fast and from the specs it appears the plunger moves at about 700Hz (353 dpi resolution at 2in/min engraving speed):

Do they utilize a very small solenoid and a very small stroke and low power? I would like to try and build a head that would be that fast.

There are also these handheld machines, which are much faster:

Hi Jan,

Do you have a photo of your impact head, or a drawing showing the construction? Could you share if so please?

May be I still don't fully understand your construction as I don't see why using magnets would be preferable over a spring?

Hi . I talk to Tomura for His plugin(TomTom) and Hi send it to me.
I want to ask You: I have to make some special settings if I want to use for impact engraving?

Can you share his email please? How can I ask him to use his plugin as well?

And how are they better than a spring?

Dan

Instead of a Spring pushing the Lever, you have 4 Magnets Two in the Lever and two more in the base each oposing another letting the lever float , when you give the impact it resists and send it Back up , when the other magnet stops it and so on

Hi Jan,

Thanks for explaining. In your video I can see a spring there as well - what is its purpose?

And how do you utilize them in your solenoid?

Watch  how my solenoid was made.I guess the mechanical design is a must.In some works I can go up to 10.000, but in others at 10000 it will leave traces between two dots.

I absolutely agree with you about this. In the video it there is no enough information to understand how the solenoid was made. Also what did you use for the coil?

Hi guys , just came to show jewels (pingents) being made by impact plcin, this time I reduced the speed...just 5000 mm/minute!
These are my son, and my wife!

Nice work, Jan. Just 5000mm/min?! You gotta' be kidding! I can't get my self-made solenoid move faster than 30 times/sec (30HZ).
I still was not able to contact the plugin creator or find this plugin elsewhere.

WOW!! 100Hz !? This is amazingly fast! On the video it doesn't sound that fast...

What is the construction of your impacter? Dimensions?

Oh.. sorry Jan. I missed that. Thank you. I built a solenoid and have been playing with it and the max frequency I can get is about 35 Hz. Above that it would just lock up. Interesting what others can get.
