Mach SDK plugin questions and answers. / Re: Impact engraving plugin

about 50 hz.
I guess this is the max frequency I can get.
Although I think 30 hz has a better finish.
I usually leave about 0.3 mm of gap between diamond tip and the material.
It was quite difficult in the begining but now i can get better results.

I ama now trying GRBL , that seems to handle usb in full . I ain't got fully satisfied yet , specially when you have high detailed pics , but it seems that is an unsoluble affair since you have the persistance of the coil movement, you have to be satisfied with the slowness of any impacter.
\it is the same as you have a strobo light...you will only see the strobo effect after a certain frequency, above that frequency you know it is still blinking, but your eyes will see a plain light.
It is the same with the impacters,you know the pulses are being sent,but the impacter has not enough speed to return to the position above the material,and ,combined to the feed rate ,you cant get it over 300 mm per minute on engraving and 3000 mm on blank areas.
I just made a symbol of Rzeczpospolita Polska ,just 100 x100 mm and took about 20 minutes.

Directly with him.
I will ask if he allows me to share.
But as Said the impact plugin that is the key of this discussion Works as fine.

Some other info;
Open in PSP the picture , make a mask around it and pitch it black around, increase contrast and use filters to show up details ( i use sharpmore) , make the image as grayscale and after  bitmap and 250( you can decrease or increase to match the measure of the image) pixels per inch.
Adjust the size in the plugin to match your granite , use a powerfull cpu, i use a I5 , with 6 gb , and a 2 gb video board , if possible use a solid state hd , it tooks seconds to load the image.
The most long work took me 7 hours, but since i have a machine with servos i let it run during the night.
The impacter i use a 24 volts , variable voltage , i generally use from 12 to 16 volts on the impacter.
I use the pin 8 to impact, just put it as digital trigger...and the signal i put on a common driver , those that they use on arduino, you can find it easilly on aliexpress,  so, i have a power source 24 volts x 5a , a dc-dc regulator , and a step motor driver , detail: jump the input of signal and direction , and jump the output, the two coil output a- and B- together and a+ and B+ together , as you have impact on your impacter you can adjust it through the dc-dc regulator

Dan , a lot of work,yes you can use the plugin that is available some pages before this , i can use the 1.2 version, but I use a version that kazuki Tomura did , It is a version of the same, it has some nice improving , he uses for laser, but you can use it with impact.
Diferently from tweakie I use a lever , but the principle is the same , although what moves on my device is the coil, the magnets stays static.
It's very useful to use because you can use the machine as a router or as impact, you can see the spindle on my machine, just behind the impacter.
here a print screen on tomuras ( tom-tom) plugin.
Notice that my mach is registered and i made a skin for it in portuguese

I used the plugin  that is almost the same that tweakie used, but it was adapted by Kazuki.
It is incredible, he manged to make it useful even in usb new boards,
I used high power magnets with a lever construction with a really strngth coil ,but with a pull movment, so i could achieve a high speed response.
I also used a step motor circuit to power the coil of the magnet, and i used a voltage regulator to dose the strength of the impact.I bought 10 diamond tips from china by 20 dollars,very cheap,and after making more than 20 granites , it is still useable,and i have 9 more to use,very cheap, i guess it is cheaper than laser.
And it really impacts the granite, or steel or glass.
Pls be free to ask question, but I advise you...it a make and mistake until you get there.

Hi guys , finally solved al the problems!
first pic is a photoshop created by me, the second engraved by impact with diamond,3000 mm per minute and modulated impact.
DonĀ“t worry about the face hadn't had lunch yet.
I must say that even in this speed it took almost 5 hours to complete the image, it was done on a 256 dpi,
It has 600 x300 mmm and made on granite.
Have been selling some images for tombstones and decoration, this kind of engraving is not known in Brasil yet, so i think it will grow in the future, my machine is made by me, with servo motors soit is very realible, and i let it work through the night

I have send you a PM . with the video link.
Good Morning (at least here!).
What I was telling you is about pictures or photo engraving.
I tried with the electro magnet , using the dll in mach ,and I tried with dotg , but it seems to me that if I want a fast drawing the impact should be continuous and the intensity of the engraving should be determined by the movement of the 'z' axis.

At exactly 4:19 you will notice a slightly variation of the z axis , and it is not determined by the suposed 'thc' system.
It seems that the impact oscillation is continuous , but the deepness is controled by Z.
The bolt gives a continuous distance between head and material using the thc up and down feature.
What I have doubt is the software they are using , it is called fotograv in some videos ,and Graver5 in others .

The thing is that is much faster than using the impact needle to impact on the way I thouht , and I must say, I need to work, things around here are too difficult, and I have some work on this field,I would be thankfull if you or any other member could help developing and making this work.

hi Tweakie,
As always see if you can help me.
I have seen excelent results in impact engraving , but not related with the dig trigger or using anything from eletronics, at least not the way we use.
I saw that the impact solenoid keeps vibrating on aprox. 0,4 mm up and down , but what engraves the material is the z axis moving slightely up and down.
This way it even engraves variabling the depth of impact causing excelent results.
What do you think about this, and wich soft should I use?
