Is the Xmodem protocol something to consider when drip-feeding CNC programs?

Yes – leveraging the Xmodel protocol built into your CNC with DNC software is the best protocol to use for error correction transfers.

What is Mazatrol CMT?

Mazatrol is a proprietary conversational programming language that is standard on all Mazak mills and lathes. It is primarily used for 2 & 2 1/2 axis work and is especially popular for turning applications.

It has a different format than G-code programming and is supported by Predator DNC by using the Mazatrol link in your commands.

How does Predator DNC Software communicate to a network-based CNC?

Predator DNC supports FTP (File Transfer Protocol) as well as Windows Share (mapped drives) for communication to the CNC.

The advantage of using this connection is faster speed and ease of connection to the network. The machine will require configuration from your network administrator to provide IPs, drive letters, user and permission controls. Some corporate networks do not allow this equipment to be connected through FTP due to security issues and potential risk of viruses.

Furthermore, most operating systems on CNCs are out-dated running Windows 95, 98, Server 2000 or NT. Updates to the operating system are not permitted typically from the machine tool builder, unlike computers used in the office.

Due to issues such as these, Predator DNC software now also supports Secure DNC, which allows encrypted communication via only two TCP ports. It can also transmit not only main programs but also subprograms and library programs to the correct folders in your CNC working memory and/or hard drive. It supports operating systems as old as Windows 95 and has extremely minimal system requirements that essentially any Windows-based CNC can meet.

It is also worth noting that Predator DNC now supports Fanuc FOCAS communication, which can rapidly send programs directly in and out of Fanuc i-Series controls. This is done without any action needed at the CNC itself, unlike older Serial send/receive processes. Moreover, Predator DNC now also supports Ethernet-based communications for DMG Mori (formerly Mori Seiki) machines running MAPPS versions II, III, and IV. This, in a fashion very similar to Fanuc FOCAS, allows programs to be sent in and out of CNC controllers, over the network, without any operator input needed at the machine.

Can I install an older Predator DNC version on my new Windows 7 machine?

No. The first Windows 7 version compatible of Predator DNC is Version 9. However, version 9 and version 10 are both compatible with Windows 8 and 8.1.

If you have an older version but would like to use Predator DNC on a Windows 7 machine, call us!

Can I upgrade and add more ports to my Predator DNC system?

Yes, numerous software upgrades are available from any level of Predator DNC Hardware. Upgrades depend on each type of hardware.

The Connect series of hardware from SFA is designed to add ports at any time and offers a very easy upgrade path. Contact us to ensure there are no issues.

Does Predator DNC work on Haas CNC machines?

Yes. Haas CNC’s can communicate to Predator DNC Software using serial RS232 connection or FTP.

Haas FTP is also supported through Predator DNC to enable faster communication. Each Haas control can be configured in the software and can be configured for any method.

Predator DNC communicates up to 115K baud rate to the Haas using Xmodem and hardware handshaking.

What are Predator DNC objects and what do they do?

DNC Objects are software options that extend Predator DNC for special customer applications.

DNC Objects can add databases, spreadsheet, and email connectivity, improve high-speed machining, offer greater lights out reliability, automatic error correction, and support for proprietary CNC controls. Predator DNC Objects support any RS232 hardware including DNC bundles, Flex series, and PC COM ports.

A DNC Object development kit is available for even further customization or integration.

NOTE: Predator DNC Clients usually do not require DNC Objects.

Does Predator DNC software support long filenames?

Yes, Predator DNC supports long filenames, long directory names, names with spaces, shared network drives, and UNC names.

Refer to the following examples:

  •     Job 1234.NC
  •     H:CUSTOM PARTSJOB 4567.NC
  •     \\SERVER1\C\LARGE CUSTOMER\PART No 1234-5678.NC

Predator DNC can also automatically name your files when uploading to the server. They can be “auto-named” using their O-number, a user-chosen name, the first comment in the file, and so on.

Does Predator DNC support CNC Remote Request functions?

Yes, Predator DNC does support Remote Request. Remote Request eliminates walking back and forth and allows operators to request files directly from the CNC control.

Can I use the Predator CNC Editor on a different PC not tied to the DNC Networking System?

The Predator CNC Editor bundled with the DNC Networking Software is controlled by the license of the Predator DNC Software. The SIM and the serial number from the DNC will enable the full version of the CNC Editor.

Currently, there is no option to split the seat from the DNC Networking license. However, you may install the Predator CNC Editor on as many PCs as you wish and use the “light” version of the product for general editing purposes.

A stand-alone full version is available if needed. Contact our sales department.
