MachPro Waterjet Setup Manual

Jet Setup

Configure the number of jets you need and your default delays. Pull down Configure -> Control - Settings.

IO Setup

Virtually every waterjet will need some of following signals. Map each of the ones you need to the correct output. 

Name Function Configuration
Jet Abrasive Output(s) Turns on and off abrasive for the corresponding jet. Map it to the correct output signal in MachPro.
Jet High Pressure Output(s) Turns on and off high pressure for the corresponding jet. Also called things like UHP On/On valve.  Map it to the correct output signal in MachPro.
Jet Pressure Output(s) Turns on and off the actual jet. Often called Water On or Jet On.  Map it to the correct output signal in MachPro.
Jet Pump Output This turns on the actual intensifier pump. If using a PLC this should trigger the PLC to start the intensifier. Often called Intensifier.  Map it to the correct output signal in MachPro.

For example, Jet Pressure Output #1 here is set to Output #6, which is an EtherCAT digital output.

Some waterjets may have some of these more advanced IO. This is more for when the intensifier is controlled inside the MachPro PLC. 

The main sequence to power on the intensifier is as follows:

  1. Turn on water (Filtered water shutoff valve). This allows water to go to the intensifier. 
  2. Turn on the Bleeddown Valve to prepare the intensifier to run. 
  3. Turn on Boost / Water Inlet Motor. This brings the incoming water up to a low PSI (like 50PSI)
  4. Wait until INLET WATER PRESSURE SHUTDOWN is active so we know the water pressure is above the base PSI. Often 3-5 seconds to build pressure.  
  5. Turn on the intensifier. Turn on Cooling Water Shutoff valve to keep the water cold. 

To turn off the intensifier, the following sequence is used:

  1. Turn off Intensifier and Cooling Water Shutoff. 
  2. Turn on Bleeddown Valve to let the pressure out of the lines. 
  3. Turn off the boost motor and the water. 

You may have inputs for HYDRAULIC OIL OVERTEMP. Configure a GMS to monitor this signal as follows:

Some waterjets have a servo controlled Abrasive. For that use these settings:

Analog Inputs and Outputs

You may have analog inputs and outputs used for setting pressure or garnet speed. Often you put them on the main screen of the waterjet. Configure them according to the device you are using (Siemens PLC Setup, or Rapidpath Beckhoff Setup).

Pump Not Working

Try running water through the jet. You should be able to get water by doing the following:

  • Activate Filter Water Shutoff Valve.
  • Activate Boost Pump. 
  • Activate Jet On. 

Cut Recovery

You can configure the axes to move.
