Support FAQs

There are a number of reasons why this could happen.

This alarm will only occur for one of two reasons:

1: The machine has not been homed after being turned on, or

2: The machine has been asked to travel to a position outside of its maximum travel parameters, either by the user or by the job.

These numbers can be found in the “Peripherals” tab of Commander in the “Maximum Travel Limits” section.

For example in the photo below, I have asked the machine to move 9000mm on X, but the X Max Travel is set to 760mm.

This is a common occurrence when you are connecting to your controller or running your jobs over a USB connection, whether it’s a Nighthawk or an XPRO-V5 or any other type of controller.

Spindles and Plasma torches create a lot of electro-magnetic interference (EMI) while they’re running and USB connections are very susceptible to interference due to the high levels of electrical noise present in a lot of common CNC environments. We have developed the Nighthawk controller with an array of communication features to combat this phenomenon. The best way to avoid losing the connection while the machine is running is to avoid using USB and instead use WiFi, Bluetooth or run jobs from an internal storage such as an SD card.

If it’s not possible for you to avoid USB connections as your controller doesn’t support WiFi or Bluetooth, you might have some success with disabling “Selective Suspend” which…

If you find the motors are stalling or stop moving during a job, such as one of the Y-axis motors or the X-axis motor, the most common cause for this is the maximum travel speed of the machine has been set incorrectly. If the maximum travel speed is set too high, the motors will try to turn faster than they are able to and will stall.

If you have one of our fully assembled machines such as a QueenBee, QB2, Metal Storm or a YouCarve these settings are pre-set for you in the factory and you won’t be able to change them. Please contact us at CNC3D.com.au for guidance.

Follow the steps below to correct this error.

1. Connect to your machine in Commander and navigate to the Axes tab

2. Under each of the axes (X, Y and Z) you will see an Acceleration and a Max Speed di…

If you find the motors are moving incorrectly or are making a grinding noise while trying to move, generally the issue is a loose electrical connection somewhere along the cable to the motor.

Before doing anything involving wiring including checking connections, ensure the controller (Nighthawk, XPRO etc.) is POWERED OFF and UNPLUGGED. Failure to do so can cause irreparable damage to the controller or drivers.

Check Electrical Connections

1. Go around the machine and ensure all green connectors are firmly plugged in to each other and cannot come apart without a firm tug, or are screwed together.
