Connection Problems

Debugging Connection Issues

Symptoms of a connection issue include not being able to detect the printer, or being stuck in an unusually long update (longer than 1 minute). To debug a connection problem, try the following: 

  • Disconnect all devices from your computer.
  • Restart the V-One software and power cycle the V-One.
  • Uninstall the V-One software and download the latest version from the website.

 Windows

The V-One Software is not compatible with 32-bit windows operating systems. Ensure that your machine is running 64-bit Windows 7, 8, 8.1, or 10. 

  • Ensure that the correct FTDI drivers are installed on your system.

 OS X

Some versions of OS X (10.10 and earlier) are likely to have problems connecting to the V-One. 

In OS X versions 10.9 (Mavericks) and 10.10 (Yosemite),  Apple included a built-in FTDI VCP driver that does not fully support many FTDI devices. This driver is also difficult to work around with the FTDI-supplied drivers, and the official FTDI VCP driver may not work at all on these systems. However, the Apple-provided driver in OS X 10.11 (El Capitan) is comprehensive enough to work with most FTDI devices. 

To ensure that your system is compatible with the V-One: 

  • Upgrade your system to OS X 10.11 (El Capitan).
  • If you can't upgrade, follow the instructions supplied by FTDI to install the VCP drivers on your system. For OS X versions 10.9 (Mavericks) and 10.10 (Yosemite), this is not guaranteed to work. 

Printer Disconnects When Baking or Reflowing

If the printer resets as soon as the heater is turned on, the likely cause is that the the wall outlet or power bar cannot handle the extra current draw required for the 550W heater. If you have multiple devices connected on one circuit outlet, consider disconnecting a device or moving the V-One.

Printer Does Not Move

Access the GCode console by pressing ` (backtick) within the V-One software. A console window willl appear, and you will be able to send Gcode commands directly to the printer. Type and enter M119 into the console to check the status of the limit switches.

The printer is equipped with multiple limit switches. As a safety measure, if a limit switch is triggered when it should not be, the printer will not move. It is possible that the limit switches may latch on.

The complete list of Gcode commands supported by the V-One will be posted soon!
