Analog Output question

[krsykes23]

Hi,

Again, I'm new to UCNC and AXBB-e, having used Mach3 and LPT's. My existing setup is a simple 3 axis machine with ATC, the usual e-stop, home and limits and tool height probe.

I also have a 4 way relay board which controls the 240v vacuum pump for hold-down, Kress 240v spindle (just on and off), ATC drawbar via a pneumatic solenoid and a laser cross-hair (5v).

In the new build (UCCNC & AXBB-e), I configured the same type of 4 way relay board and have successfully configured the two 240v outputs (M3 and M7) and the ATC drawbar (M8) using the
Non-Isolated output (pins 15, 16 and 17) but I now need help with the 4th relay. BTW, the relay board uses 5 volts

I assume I can use the Analog Output (AO1)? If so, how do I configure the output pin, as I notice in the settings for I/O, it shows a VAR#?

Basically, I need four outputs with 5v....I have three configured but how do I connect the fourth?

The analog is for an adjustable voltage control to a spindle drive. NOT for use with a relay.
Read paragraph at the bottom of page 21/29.
Either 1, get a 24v relay to use on the isolated output side.
2, do as paragraph states with regard to different voltage relay use.
3, get another cheap breakout board and idc26/bd25 cable and use that on port #3. Use that port for all your relay switching.

Thanks for the reply, much appreciated.

I've ordered an 8 way 24v relay board. Stupid question....how do I assign the Isolated Outputs on Port#1? With the ones I mentioned earlier (M3, M7 and M8), these were pre-defined options
in the Settings, but I'm puzzled how Port#1 Isolated Outputs 1-8 are configured. I just need to assign individual buttons on the screenset. In Mach3, obviously Spindle is self-explanatory, while
the vacuum pump utilises M7 and the ATC drawbar solenoid uses M8. I did search the manual but couldn't find, or more to the point didn't understand it!

I'd be grateful for any further help.
