XHC MACH3 MKS V control board issue
Hi all,
I've purchased a China CNC 6040 with XHC mks v control board. I'm trying to setup a solenoid to control cooling but unfortunately so far despite lots of reading I've been unsuccessful.
I'm using Mach 3, which already has flood/ mist control assigned to output 4. This is ideal I thought, wire up the relay to the control boards 5V output then use output 4 to turn the relay on/off.
However when I use the M7 gcode to turn the mist coolant on nothing happens, I've measured the voltage and on it measures -0.5V and off 0V.
I'm completely lost as to why the voltage on output 4 is not high enough to activate a relay.
Does anyone have an idea as to what is wrong or anything else I should do to get coolant running?
Please see the attachment images
Many Thanks
Colin

When I did mine on my different bob it didn't work either. Turned out my control board was a negative output to axis. So I had to wire my SSD positive to my 5v+ supply and my negative - to the axis pin. Can't remember off hand whether mach then had to be active high or low.
No guarantees cable swap rounds will work for you though.

Are you sure port 1 pin 3 is the right configuration?

Re: XHC MACH3 MKS V control board issue
Thanks Guys,
In the end I got it to work using a 24V power supply and 24V relay. I ran 24V between Output 4 and 0V outputs and was able to toggle the relay on/off using the M7 & M9 commands in mach 3.
No idea if its possible to use the 5V outputs.
I just need to configure the E stop now, which for some reason does nothing.
