10.11 Limit Switch is Triggered in Mach3
If there is an unknown problem with the machine, go to Mach3 > Program Run and check the
Status text box. The Status text box will display if a limit switch or E-stop is triggered. Then go
into Diagnostics and determine which limit switch is lit up and/or check E-stop switches on the
machine.
If it is determined a limit switch or E-stop has been triggered, Home the machine.
If the limit switch keeps triggering after Homing the machine, click the Config drop down menu,
click Ports and Pins, click the Input Signals tab and disable that limit switch until the cause of
the problem is determined (bad limit switch, limit switch out of adjustment, bad cable, etc.).
Click APPLY, Click OK.
Try to enable the machine and Home the machine with the limit switch disabled. If successful,
contact Bend-Tech to replace the bad component as soon as possible.
10.12 Leaving Mach3 Open
If the Mach3 interface is left open when the Bend-Tech Dragon software and the Dragon
machine are shut down, then upon booting up the computer, a message window will pop up
saying the Ethernet Smooth-stepper has failed to communicate for an extended period of time.
When this occurs, click OK.
If the Main Power Switch is turned on and the green button is pressed on the Control Box,
the machine will boot up normally. When Machine Control is opened, the control interface will
display Machine Disabled as it normally does. But, when the button to enable the machine is
pressed, the machine will not enable. A message will appear that reads, “Unable to bring the
machine out of an emergency state.”
Clicking into Mach3, will show a blinking red Emergency light in Diagnostics and reseting the
machine through Mach3 will not work in this Emergency state.
At this point, Mach3 is not connected to the machine. The solution is to close out of the
Dragon software and the Mach3 software. Then turn off the main power switch on the Dragon
machine, and restart in the proper order.
