[575] I connected this to 24v power supply and only out3 will show 24v when activated the other 3 read 300+v whether activated or not

Make sure that the spindle motor output pin is not interfering with the signal. Go to config -> ports and pins -> motor outputs, at the bottom of the table, there will be a line for spindle. Make sure that spindle line item is disabled. Additional Information: I disabled the spindle port and I am still only able to activate port 3 and get 24v and even there when I enter m5 the voltage bounces all over the place. The other outputs read all over the place whether they have been designated as the spindle on the spindle settings tab Additional Information: I tried wiring a relay to each of the outputs and only out3 was able to activate the relay
