Mesa 7i96 Ethernet board

I'm not sure what the max hertz will be just yet. My design is not my own but taken directly from a service manual of a wire edm. Also I have the manual from the Sodlick edm I'm retrofitting and reverse engineered the spark box to some extent. When I bought the machine the control did not work, but it was complete. It would seem to me that using pwm would be great for a foam cutter.(variable voltage) but not very good for creating high frequency sparks needed for wire edm. And yes you also need to control one time (dwell) as well as speed. I thought step pulse was a good fit. The primitive spark boxes use a 555 timer. I was just kicking it up a notch to have it on the gui with everything else.

Here are some of the design files for you to look at.

The mossfet I'm using. oh and having a opinion about something you have never done just makes you a critic.

obviously you don't get that having multiple mossfets allows you to control the amperage. Here again you have never done this.

Hello! Help configure the Spindle and Output section (spindle on) in the 7i96 Configuration Tool. Firmware 4 Step Gens and PWM. Spindle open loop 2.2kw. 400Hz.-24000Rpm. If you can correct my files. Thank!

Recent versions of master support multiple spindles so the spindle related pin names have changed, I believe what you want is:

spindle.0.on

("man motion" for all the new names)

I use the last master. I want the LED on the corresponding spindle to start up when the spindle starts up, as for a spindle cooling pump. What do I need to fix for this and where?

Thanks for the hint! Understood, should be removed in io.hal before spindle.0.on motion. and one error disappeared as well in the linux_mesa7i96.hal section of the Spindle line setp hm2_7i96.0.pwmgen.00.output-type 0 instead of 0 is one of (1,2,3,4). Thank you so much! Everything worked as desired.
