EZ TRAK DNC from floppy

[ind_dsnr]

Hello all,

I'm new to the forum. I've searched and could not find any info on running DNC programs from a floppy on a 2001 Bridgeport EZ TRAK. I've tried checking selection #4 from the menu (DNC) and still cannot run DNC from the floppy. Do I need to change the program file extension to .DNC? Any help would be greatly appreciated.

I'm not real familiar with the EZ-Trak, but most machines that run DNC expect to receive the program over a serial cable from another computer that is running a terminal emulator. The files would be in ASCII text format, with a .txt extension.

I do not know of anyone trying to DNC a EZTRAK (nor have I done it) but I do know the 3 axis trak has that capability. The manual should explain the rules. In all probability it would be a G and M code program (with a .TXT extension) of a 3D application. What created the program? Is the format correct?
If G and M it would have to be considered a other type of file and run as such (as opposed the the conversational .PGM file). Usually the file to DNC is transferred to the hard drive (or other mass storage device such as DOM or Disk on a Chip).

Hello,

I helped out another EZTrak user several months ago on this same issue. Check out this thread.

You can DNC both file formats, Use one of these extensions .pgm or .txt I usually use the .pgm format because it is easier to edit at the control.

Don't use .dnc

You can DNC from either the hard drive on the machine or from the floppy drive.

Thanks for all of the input. I was back at it this weekend. At first I had to monkey around on the keyboard to get it to load the program. It wouldn't load the first line of code but I found a solution. I selected find sequence in the menu and entered 1 for the first sequence. After few successful attempts at running a program in DNC mode my solution stopped working. It simply wouldn't load the first line of code from the floppy. I got the same results when loading from the internal memory as well. The screen would read "DNC" as well as the file name. I tried restarting the machine multiple times with the same results. I'm using Bobcad to program the tool paths and have tried a few different EZTrak post processors. DNC would only take .txt files while it was working. It rejected .pgm files in DNC mode. The machine still uploads .pgm files to the buffer and runs fine. Any thoughts?

After you load DNC and it displays DNC on the control, are you putting the control into AUTO ?? Hit one for AUTO. Just a guess. See pics.

If you want send me one of your programs and let me try it on my machine.

Thanks Pete,

It didn't even occur to me to try Auto. I'll give it a go this weekend.

This is the error that I got when trying to load a .txt file for DNC. I've selected auto mode. I got a program to load once, then got the Internal Sequencing error #10. Does anybody have any idea what it means?

Ran across this post while looking for something else. Not sure if you resolved the problem but there are two things to check. 1) Look at your sequence numbers. I own an EZTrak and use BobCad. One of the BobCad post would use sequence number 0000 on the first two lines. The program will need to be resequenced with either BobCAd or in Edit mode on the EZTrak so that the sequence numbers are sequential from the first line on (0000, 0010, 0020, etc.). Keep in mind, on the EZTrak, it will only re-sequence up to 9999 lines. Anything larger has to be done off the machine. 2) Next, the BobCad post would also only place a feed command at the end of the first line move. EZTrak needs a feed command on each line containing a canned cycle. If there is no feed rate called out, the machine will stop.

I know this post is old, but I know the value of the resources of this forum. I use it on occasion to track down solutions to problems. The post originator may have figured out the problem but anyone else finding this post later with the same problem may need all the information they can get.

Thank you for your reply to my post. I apologize for not posting my solution. I hate when I come across dead-end threads. I was able to get the machine to accept the DNC from the floppy after fooling around with some of the hardware. It turned out that I needed a replacement floppy drive. Everything is going smoothly now.

Thanks again.
