Mach4 is a CNC motion control software developed by Newfangled Solutions. The Mach4 SimpleMotion drive plugin is needed to run motor drivers connected to SimpleMotion bus with Mach4.

Requirements

The following things are needed for building a CNC machine using Mach4 and motor drivers connected with SimpleMotion bus:

  • Atomi, IONI or Argon-based motion system, e.g. CNC mill, connected with SimpleMotion bus
  • Windows PC
  • Mach4 software + license
  • SimpleMotion adapter depending on selected motor drivers

Mach4 installation

  • Download and install Mach4
  • Download the plugin files to the Mach4 plugin folder
  • Read the Mach4 installation, configuration and operation manuals before use

Configuration

Motor driver configuration with Granity Software

This section shows the basic configuration for motor drivers with Granity software. More support for using this software can be found from the Granity user guide. The following subsection titles are links to corresponding guide pages. Download the Granity software from its wiki page, launch it and follow these steps:

Connect to the motor driver

Connect to a motor from the "Connect" tab by selecting the interface device, and clicking "Connect to drive" GranityConnect.png GranityConnectSelectDriver.png

Testing

Mach4 configuration

Open the Mach4 Configuration dialog

MachConfigurationTab.png

Enable the SimpleMotion drive plugin from the plugins tab.

MachConfigurationPlugins.png

The program should ask to restart Mach4 after enabling the plugin. Restart Mach4 before continuing.

Select the SimpleMotion drive plugin to be used as a motion device

Configure the motors

Open the Mach configuration again, and select the motors tab.

Select each used motor and configure them as following:

  • The motor indexes are always one smaller than the SimpleMotion axis numbers. For example, Motor0 means drive 1 in the SimpleMotion bus.
  • How many steps the motors should move for each unit of measure
  • The maximum velocity of each motor
  • The maximum acceleration of each motor
  • Motors can also be reversed here

Axis mapping

Enable the axes used in your machine. The following picture shows 3-axis machine where the spindle motor is also controlled by Mach4. The axes X-C (0-5) are for motion, and the OB axes (6-11) can be used for controlling a spindle motor.

  • Enable used axes
  • The motor indexes are always one smaller than the SimpleMotion drive numbers. For example, Motor0 means drive 1 in the SimpleMotion bus
  • Select a motor for each axis. Slave motors can also be set for an axis if they use more than one motor
  • Do not enable axes without motors
  • The spindle control type (velocity or position-controlled) will be set later

Homing / Soft limits

  • Set the homing order. If some axes have the same number, they will be homed at the same time
  • Enable soft limits for motion axes
  • Set the soft limits to prevent axes from hitting their physical limits. If you don't know what to put here, you can also configure them later
  • The homing direction, offset and speed are selected in Granity software when using this plugin

Spindle configuration

  • Set min. and max. rpm for the spindle motor if it is controlled by Mach4.
  • The max. rpm set here doesn't have effect to the real speed of velocity-controlled spindle. Running a velocity-controlled spindle by here configured max. speed runs the spindle motor by the maximum speed configured in the motor driver.
  • If the spindle is position-controlled, the spindle motor should be selected in the "Step/Dir Spindle Axis"-dropdown. The axis must be enabled and mapped before this.

SimpleMotion drive plugin configuration

Close the Mach configuration and open the SimpleMotion drive plugin configuration

PluginConfigurationTab.PNG

Set the following settings. The default values work in most cases.

  • SimpleMotion V2 adapter FTDI port number
  • SimpleMotion V2 buffer max. fill percentage
  • In the case of using a velocity-controlled spindle, its axis should be selected here. The list shows only mapped and enabled axes that are not selected as position-controlled spindle

Save the SimpleMotion drive plugin configuration by pressing "OK", and start using the software!
