Hello!
Can you tell me, the outputs on the mk3/4 latest version, go through the buffer or directly from the processor?
I have connected the frequency converter through the optocoupler (out1,2) and out6 pwm 5V directly to frequency converter, It supports 5V PWM.
It worked fine for 15 minutes, and then the spindle turned off. Now, with the outputs activated, the voltage is 0 at all outputs
