Troubleshooting 

 
Most error messages can be viewed in the history log of Mach4 and can indicate problems with the configuration 
or the runtime operation. 
 

 

 

 

 

The system disarms when calling the M3 command 

 

Cause 

Solution 

One of the THC settings may be bad. 

Review the THC settings on the ArcPro screen and make 
sure that the 

[THC On]

 is enabled and mapped to a 

digital input on the motion controller.  

The 

[ArcOK]

 or 

[DIGITIZE]

 signal is 

currently active. 
 

Check the Mach4 Input signal mapping, and make sure 
that the polarities (Active Low/High), are set to the 
correct values. Inspect the wiring and make sure that 
the LEDs on the Arc Pro screen toggle properly. 

The controller was busy executing another 
motion sequence. 
 

In most scenarios, this error shouldn’t occur. Check the 
GCode File or MDI command being executed before the 
M3 command. 

The probe move reached the indicated 
limit without detecting the digitize signal. 

Check that the 

[Digitize]

 signal in Mach4 is mapped to 

the correct digital input, and that the 

[Digitize]

 signal 

toggles correctly by checking the signal state in the 
diagnostic tab on the Mach4 screen. 

 

The THC feature is currently not activated 
on the unit. 

Please contact the vendor of your unit, or Vital System 
Inc. 

 

NOTE: It is also recommended to go 
through th

wiring diagram

 for safely 

connecting the digitize sensor to the 

motion controller. 

NOTE: Please follow the proper setup instructions for wiring, Mach4 

configuration, and the setting the on-screen THC parameters before attempting 

any tests.
