Glad to hear it is working. Now we usually recommend enabling the charge pump feature on the PMDX-126 to help avoid spurious outputs while the PC is starting up or shutting down. This uses pin 17 on the parallel port, so if you are using pin 17 for something else you cannot enable charge pump mode.
If you wish to to do this, here are the steps:
- Change the PMDX-126 DIP switch "Config 1" to "open" (away from the silkscreen text)
- Press and release the test button
- The PMDX-126 "Outputs Enabled" LED should remain off
- If you are using Mach3, go to the Configure menu and select "ports & pins". Click on the "Output Signals" tab and scroll down to "Charge Pump". Put a green check mark in the "enabled" column, then assign it to port 1 pin 17. Click "Apply" then "OK"
- If you are using a SmoothStepper or other pulse generator instead of a PC parallel port, refer to the documentation for that device to see how to enable the charge pump.
- If you are using Mach4 with one of our PMDX-SmartBOB devices, the procedure is very similar to Mach3 except you go to the "Configure" menu and select "Mach". From there it is the same as Mach3.
Now, the PMDX-126 "Outputs Enabled" LED should remain off until you enable Mach3 (the "Reset" button is not flashing) or Mach4 (the "Enable/Disable" button is green), at which point the "Outputs Enabled" LED should turn on.
