Boa noite, sou brasileiro, a muito tempo venho trabalhando em um pulsador pwm para uma EDM, usei um esp32, controlando uma banca de IGBT,s esse sistema pusa em frequências acima de 10khz até 100khz. Conseguindo controlar o dutycicle com uma corrente de 50A

Estou com vontade de fazer uma wire EDM depois .. gostaria de intender como você fez pra ele andar somente quando a corrente para de circular

Good evening, I'm Brazilian, I've been working on a pwm pulser for an EDM for a long time, I used an esp32, controlling an IGBT bank, this system puts frequencies above 10khz up to 100khz. Managing the dutycicle with a current of 50A

I feel like making a wire EDM later.. I would like to understand how you made it run only when the current stops flowing

Did you ever finish your retrofit? I have a Sodick that needs the same, I made a spark generator that seems to work so I am now ready to start the machine control part. I would benefit from your experience!

There are several EDM machines using LinuxCNC on youtube, BaxEDM is one of them who builds and sells complete machines.
For retrofit, check if the existing drives and motors work and what control signal they accept, usually step/dir or analog +-10V.

Is BaxEDM implementation of LinuxCNC publicly available or do you have to buy his spark generator to get it?

Try asking here as he will get a notification of reply on topic he started
forum.linuxcnc.org/10-advanced-configura...e-feed-range-problem
Or write a comment on youtube, he has a channel with the same name there.
Not both at the same time, use one, wait a day or two then use the other.
