Understanding M238 CNC Code
When working with CNC machines, you may come across the M238 code, which can be confusing if you’re not familiar with its functionality.
The thing is, M238 isn’t a standard M-code in the CNC syntax, so its functionality varies depending on the specific machine or controller you’re using.
In some cases, it might be a custom or user-defined M-code controlling a specific function or output on the machine.
To understand what M238 does, you’ll need to consult the machine’s manual or manufacturer’s documentation, as its functionality isn’t defined in the standard CNC syntax.
MachMotion CNC Controls Overview
With MachMotion CNC controls, you’re working with a system that harnesses Mach3 or Mach4 software to operate and customize your CNC machines.
This software allows you to control and tailor your machine’s functions to meet your specific needs. M codes are used to control various machine operations, and MachMotion provides a reference list of these codes for your convenience.
When using MachMotion CNC controls, it’s essential to enable relay outputs on the breakout board to guarantee proper functioning. You’ll also need to set the port to 2 and the pin to the corresponding relay for outputs 5-12 to work correctly.
Custom M-Codes for Relay Outputs
You’ll use custom M-codes to control relay outputs on your breakout board in MachMotion CNC controls.
To get started, you’ll need to set up the port and pin correctly, with outputs 5-12 requiring port 2 and the corresponding relay pin.
MachMotion provides a reference list of M-codes to guide you through this process.
Relay Output Control
To control relay outputs 5-12 on the breakout board in MachMotion CNC controls, custom M-codes M238 to M245 are utilized.
You’ll need to set the port to 2 and the pin to the corresponding relay output to use these custom M-codes. Additionally, relay outputs 5-12 must be enabled on the breakout board to function with custom M-codes M238 to M245.

Enabling Relay Outputs on Breakout Board
You’ll need to enable the relay outputs on the breakout board to use custom M-codes in Mach3 or Mach4 software.
To do this, set the port to 2 and pin to the corresponding relay output number (5-12) in the MachMotion CNC control software.
Proper breakout board setup is vital, so make sure to configure it correctly to control relay outputs 5-12 using custom M-codes.
Enable Relay Outputs
How do you enable relay outputs on your breakout board?
To start, you need to verify that outputs 5-12 are correctly configured. This requires setting the port to 2 and the pin to the corresponding relay.
With MachMotion CNC controls, which use Mach3 or Mach4 software, you can create custom M-codes to control relay outputs. Enabling relay outputs is vital for effective machine operation and control.
You’ll need to use relay control methods, such as custom M-codes, to configure your output configuration and board settings. MachMotion provides a reference list of M-codes to help you with this process.
Set Port and Pin
To enable relay outputs on your breakout board, you need to set the port and pin correctly.
The M238 CNC code is used to set the port and pin for relay activation on the breakout board in MachMotion CNC controls. To do this, you’ll need to set the port to 2 and the pin to the corresponding relay number, ranging from 5 to 12.
This custom M-code allows you to control relay outputs on the breakout board. Make sure the relay outputs are enabled on the breakout board before using the M238 code to set the port and pin.
Breakout Board Setup
Configuring the breakout board to enable relay outputs is a pivotal step in controlling your CNC machine’s outputs.
To do this, you’ll need to set up the breakout board configuration correctly. Outputs 5-12 require the port to be set to 2 and the pin to be set to the corresponding relay. You can find specific configuration details in the MachMotion documentation.
