Duet 3 6HC max pwm is only 3.8V
-
Im trying to connect a vfd to out 9 using this pwm converter https://www.amazon.com/dp/B091B6LGXB?ref=ppx_yo2ov_dt_b_fed_asin_title
When i measure the pwm signal it is only putting out 3.8 volts when i turn the spindle on at the max rpm of 24,000. The voltage out is only getting to 9V.
