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

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.

Another thing that I would know it is how to set the driver L298 and TB6560 in full step, half or other.

Dan, just take a look at a tatoo drawer, it´s exactly where i took my idea, and afterwards I took of the spring and used magnets. there is a coil(electric) on one end, and is sided by two powerfull neodimium magnets, this gives the movement, in the oher side , before the diamond tip i had a spring, now i have 4 smaller neodimium magnets, that always repels themselves.I pluged the coil in a stepper driver , shutting both a+ and B+ in one side and both a- and b- in the other wire , i shuted (jumped) both dir and step inputs on the s' or digital trigger from the board to the step driver , this will be the same as a laser ttl+ and ttl-.
In the compiling make the signal be more than 90 ms , or you won´t have impact, but a noise.

Hi, it will depend of what kind of hardware you are using, the best I could achieve was using a l298 and a dc-dc step down.
The thing is that the digital trigger from Mach3 must be conected together in step and dir of the l298.
don´t worry about english, I'm from Brasil and my english is terrible!
I am now triyng to find a different approach , instead of just using digital trigger, i am tryng to combine it with the pwm signal using  the attached software to generate the  g-code,
Give it a try , you can choose between S or Z generation , one will be used on digital trigger the other can be used to engrave slowly and with z .
The soft is in brazillian portuguese

See this scheme , maybe will help you.
Yes...it is paint ,lol.

Hi, great work, I am very interested at this application, I have read all the messages but I am not sure if the connections are right for mach3, but i have not any idea how to connect the wires if I want to use Arduino Uno R.3. Other thing that I don't find are the number of stepps for mm. that I must write in the configuration in mach3 and for Arduino Uno.  I use on my cnc  a board 4 axis all in one based on L298 with a voltage of 45 VDC (https://shop.strato.de/epages/61125483.sf/de_DE/?ObjectPath=/Shops/61125483/Products/%22SM44PCV5.2/RK2%22) but if I want use this application I must detach the fourth axe and to use an external bridge for the coil (max 24 Vdc) or I may use the two bridges based on  TB6560 that I have made for another little cnc to use Arduino Uno.
Other thing that I don't understand is how to build all the system for the impact because it isn't clear how to install the magnets and especially the coil. I hope that you help me.
I enclose a photo with the connections to know if they are right for mach3.
Claudio.
