Hey Thomas,
did you check the M8 (Turn flood coolant on) command by entering it manually into the command entry field of the manual data interface (MDI)?
If you have an Elite/Masso controller and Elite power supply, it should switch the power on on the NEMA 5 socket labeled “VACUUM” on, but only if it is powered by the separate C14 power inlet which is positioned below this one.
Usually in this forum, if you have a “Onefinity Controller”, which means the CNC controller was hardware- and software-forked from Buildbotics and is further developed and produced and assembled by Onefinity, you mean the Buildbotics-derived Onefinity Original Series CNC controller. It’s the controller explained here.
If, on the other hand, you have an Onefinity Elite Series machine, your controller is a MASSO G3 Touch CNC controller, with a proprietary power supply / relay unit which was developed, produced and assembled by Onefinity (not by MASSO).
So either you have a “Onefinity controller”, which means the (buildbotics-derived) CNC controller produced by Onefinity, found on X35/X50 Original Series, or you have the “MASSO G3 Touch controller”, found on Elite Series.
