Configuring LinuxCNC

Configuring LinuxCNC

• First copy one of the sample config directories from /usr/share/doc/linuxcnc/examples/sample-config to ~/linuxcnc/configs/ or follow the instructions under CustomizingConfigsOnUbuntu (outdated)
• Then, modify the .ini file located in ~/linuxcnc/configs/ to suit your machine [as described here]
• You can select between various user Interfaces
• LinuxCNC uses a Hardware Abstraction Layer (HAL) which is very configurable. You can easily map any signal to any hardware pin, or modify signals with hal components as if they were real analog or digital electronic signals. See SampleParport for an example.
  • There is available a [HAL tutorial] that specifically describes how to change the pinout of a parallel-port stepper machine, including the addition of an external ESTOP input. See [here] for details.
• ClassicLadder, a software PLC, has been added to LinuxCNC. It allows plenty of flexibility for creating custom machine logic, in a format that most integrators are familiar with.
