Hi Jan,

Thanks for the details and sharing the program. So you have two coils connected each to one phase of the driver, and one coil pulls while the other pushes the plunger. So in this connection each pulse signal into the driver corresponds to one stroke of the plunger? First pulse - pull, second pulse - push, third pulse - pull, right?

But if you stop the pulses you don't know which state did it end in?

Also I tried your program, but didn't understand the Gcode it outputs. Only has "S0" at the beginning and "S0" at the end. In between only XY moves. So what driver the coils?

Thanks,
Dan

S0 means no impact and s1000 means full impact , between these two the soft gives values that goes from light gray to dark gray and black (s1000).

So if you want the soft to stay with the diamond needle up in the end of the job, just add a s0 in the end of gcode in the window .

"Thanks for the details and sharing the program. So you have two coils connected each to one phase of the driver, and one coil pulls while the other pushes the plunger.

No, almost that, the two pulses are alligned with the magnetism in the master  neodymiun , so that it goes just down as much as the pwm adjusted , the coil and oposite neodymium in the point of the lever do the up effect , after each impact , no matter if it is S200 , S500 or S1000 , after each of them you will have a S0 so the driver is cut off ,

What drives the coil is the driver, but what comands the driver is a pwm signal , in themajority of control boards you will only be able to use it as Dithering , not grayscaling, because the majority of breakout boards will only reconize the pulses as 0vcc - (s0) or -5 vcc (s1000) , my board reconizes a scale from 0vcc to -5vcc as frequency 0v-no frequency, -1v more frequency until -5vcc ( 300 hz) .

But even if you use a commom board yo will have excellent results ! just play with feedrate.

Save your pics on dithering and you will have just up and down without grayscalling.

I'm preparing a soft in english , so that it will be easier to understand .

After having seen the video of Jan Mozol and all that he has written and also this other video https://www.youtube.com/watch?v=bEB-hN3Fnek  I believe that a departure point for the mechanics with the magnets might be that represented in 2 enclosed drawings.

Almost there Captain ! the solenoids should be mobile and the neodimium fixed!

what is this secrecy?why can't somebody put here the picture of magnetic impact head? is a secret? we want to do this impact head but we need some help.for me is a hobby the CNC is ready but I need some draw with this head.
Help,help.!!!
Thank you!

Well this is where the fun is! Just a hint...I don't use my solenoids as the drawing above , I use them on a vertical way between neodimiuns!

Just find fotoengraving.exe in the uncompressed files and click on it.
See that you have two options to use the trigger, one using 'z' as signal and the other using pwm (0-1000) -this is my prefered because you can obtain grayscale altering the speed of x axis and it will change the frequency ( this depends on wich control board you are using)

Since I use the pwm in digital trigger, i just add a 0 pwm comand at the end of the g-code

like this:

S0
X0Y0

If you are interested i can send my gcode generator , by the way, I can send to everyone- here: ( it is in portuguese )

Hi Dan13 , the solution is simple: you can use 2 coils in paralel conection (I mean in magnetic way, not electric) and conect the two outputs one to each driver output .I've done this way using two solenoid coils and three magnets ,

Thanks , could you give me direcions if is it possible to use a digital trigger in modbus?

Hello Zafar..i'm a newbie on this, where can I get Vinys code? and should I just upload it to a clean Uno?

Cláudio..mach3 will work with arduino through modbus.
Tis a little more complicated.Go with paralel port if you are not a sénior user.
Plus the concept of magnets is not so easy arranged Like that.the 298 should work bit you need a dc-DC step down. Send me a e-mail tonight i will be answering them
