I'm hoping someone can help me out with a newbie question. I have a Stepcraft MM-1000 DI milling motor (which is basically a rebranded Mafell FM 1000 PV). This is equipped with a 4-pin "PV interface." Is it possible to connect this directly to the BlackBox X32? If so, could someone help me figure out which wire goes where? I've attached the wiring diagram from the user manual as a PDF. I've also found several sources for connecting to a Duet, but I don't have a firm enough grasp on this part yet to get beyond following exact instructions. Those sources linked below, along with the basic gist of the wiring setup. Thanks for your help! Nigel Wiring a PV Cable from a Mafell Router into the Duet? Connect a AMB Kress or Mafell spindle with digital control The cable for the 4-pin connector uses this setup: Pin 1 : Upv : Brown = power supply (PV Interface) Pin 2: Us : White = control voltage speed (PV Interface) Pin 3 : Uo: Black = display remaining runtime in overload mode (PV Interface) Pin 4: GND: Blue = reference potential for voltages of the PV Interface
Seems to me it is as simple as connecting the "GNG and 0-10v output" on the BlackBox to the "GND and Us" connections on the Mafell Then set the $30 and $31 values in the GRBL settings to the correct values as well. Dont forget to calibrate the 0-10v output before connecting. once connected and configured a command like M3 S14000 will turn it on at about that speed and M5 will turn it off.
Thanks, David! That makes sense. Now that I'm looking ahead at the GRBL settings and G-code it's starting to click a bit better. It's that power supply wire that is still throwing me. It seems to suggest that the onboard controller needs DC power to operate, separate from the AC power to the motor. Anything from 8-56 volts, otherwise it sticks to manual operation. I guess we'll see if I'm able to control it with that cable capped off and go from there. I'll report back when I get around to this! Thanks again.
