SmartBOB controllers and dedicated accessories / Wiring Price CNC Torch Height Controller to PMDX 424BOB

« on: January 05, 2022, 07:56:15 AM »

Good Morning, A little bit of a wiring question as to hooking up the Price CNC THC to my 424BOB? The THC has an “anti dive” function to it which “receives an Anti Dive signal from Mach 3 via breakout board”. The voltage is between 2 - 50 vdc for this function to operate in. Yellow wire is “postive”, Black wire is “negative”. It states to use an “Output” terminal or spare “Axis” to wire this into? I am going to use “Output” terminals @ “J-12” wiring Yellow + to “pc+5 and Black - to terminal #1. Obviously if i wired the negative to ground this would continually get 5 volts, using pc+5 and terminal #1 this will switch ON or Off via Mach. Does this seam correct? I’m running Mach 4 Plasma with my PMDX424 just as an fyi not Mach 3, don’t think that is an issue.

SmartBOB controllers and dedicated accessories / Pmdx Plugin not remembering settings!

Hi,
   I recently got my Mach4 and PMDX 424 working together to do some bench testing but when making some changes within the PMDX plugin the changes are not saved when closing Mach4 even after checking OK box on plugin after changes have been made. When i bring Mach back up and run the plugin the changes are not there as the plugin reverts back to its default settings.

SmartBOB controllers and dedicated accessories / 542T Stepper drive fault light using pmdx424

« on: May 21, 2019, 08:29:16 AM »

Hi to all, i have built a cnc controller box for a plasma machine using the pmdx 424 motion controller. I am using 4 omc stepper online nema 23/425oz motors driven by the M542T drivers 4 each. I am having issues with the drivers tripping into the fault mode every time i try to do a manual jog from my laptop using mach 4. I have tried wiring Dir and Pul both ways (com+ & com-) it still sets off red fault light. I have tried this with motors disconnected and still trips the drive. I am using 36vdc power supplies to power 4 drives/4 motors. I believe all wiring is correct with no Enable connected as well? Have tried different settings within the pmdx plugin as well, no success. Help!
