Transferring SMALL Files from the classroom

8. Locate the file you wish to send and double click on it to execute the transfer.

9. Your transfer is complete. You may close FileZilla and move to the CNC machine to work with your program.


22


Transferring SMALL Files from the CNC machines hard drive to Active Memory NOTE: This procedure is performed at the CNC machine

1. Set the I/O channel to 5 as described on page 28 of this manual. 2. Press the EDIT MODE hard key 3. Press the PROG soft key

4. Press the + soft key once

Step 3

Step 4

Step 6

Step 7


24


Transferring LARGE and SMALL Files using a Flash Card The available storage (memory) on a CNC machine is very small (approximately 64k). We will transfer files using the Flash Card when the CNC files are smaller than 60k or too large to fit into the machines memory (larger than 60k). Small files are transferred in their entirety, large files are executed from the flash card a few lines at a time and are not kept in the CNC memory. You must first have a USB Adapter with a Compact Flash Memory Stick and also a Compact Flash PC Card Adapter

USB Adapter

Compact Flash

Memory Card

Compact Flash PCMCIA Adapter


25


Transferring LARGE and SMALL Files using a Flash Card

A Flash Card appears in Windows Explorer as a removable drive or mass storage device e.g. (Compact Flash F:) Copy your data (CNC file) from your computer to the memory card.

NOTE: When finished copying files, be sure to use the Safely Remove Hardware button in the System Tray

to stop the flash (memory) card BEFORE removing it from your computer. Removing the card without stopping it will likely corrupt the card and render it useless.

This is the memory card


26


Transferring LARGE and SMALL Files using a Flash Card Remove the flash (memory) card from the USB adapter and plug it into the PCMCIA Adapter as shown below.


27


Transferring LARGE and SMALL Files using a Flash Card Insert the PCMCIA Adapter into the socket located on the CNC machine. You may have to open a small door to see the empty socket. Be sure the front of the flash (memory) card is facing the CNC machines video monitor.


28



It may be necessary to set the I/O (Input/Output) channel to connect the CNC machine to the flash (memory) card. Follow the procedure on the next several pages to set the I/O channel.

1. Press the MDI MODE hard key. 2. Press the OFFSET SETTING hard key.


29



3. Press the SETING soft key (the following screen is displayed)


30



4. Use the down arrow key to highlight the I/O Channel and then touch the number 4 (to access the Flash Card) or 5 (to access the CNC hard drive) key as shown below.
