Configure a RapidChangeATC Tool Changer on MachPro
Use the RapidChange Documentation Portal and your motion controller documentation to install and wire your RapidChange ATC product. You will need to wire 3 inputs and 1 output, then map them to software signals in the MachPro configuration. Then create your profile on the RapidChange web app using those software signals.
Inputs
Configure -> Control ->Input Signals tab
MachPro has commonly used signals pre-configured to make your configuration process quicker.
Please update the device and input for the signals that you will be using. Then disable and clear all signals that you will not be using.

Set MachPro to use your RapidChangeATC
Set the Tool Changer to RapidChangeATC.
- Pull down the MachPro menu Configure -> Control -> Settings tab. Filter for Toolchange
- Change Tool Changer Machine Brand Specific Operations to RapidChangeATC and click OK to save your changes

Create and install a RapidChangeATC profile
- Go to the RapidChange Web App (profile configuration) to configure a RapidChangeATC profile for your machine. Use the MachPro documentation section at RCATC Docs for the details on each section of the profile.
- At the end of the setup you will download the RapidChangeModule.lua file to your computer
- Close MachPro and copy the downloaded LUA file into your Mach modules folder: C:\Mach\Modules.
- If you are updating an existing profile, first delete your previous C:\Mach\Modules\RapidChangeModule.lua before copying over your new profile.
- Rename the downloaded file to remove any version numbers (example (2).lua) from the file name after copying it into the Modules folder.
How it works
Switch to the Tools tab and click the tool number that you want to switch to.
The RapidChangeATC module will now control all of the motions of the machine while it switches tools and touches off the tool setter to set the tool length. All of the coordinate moves, locations, and rates are determined by the values in the RapidChangeModule.lua file. Refer to RCATC Docs for the specific details.
Optional
You can configure a RapidChangeATC tool setter to be used outside of the normal tool change sequence. This is optional, and not necessary for normal tool changes.
Use the instructions at MachPro Tool Setters and Offsets. You will need to re-enter some of the machine coordinate locations, and you should use the values you entered when configuring your RapidChangeModule.lua profile.
