Need Help!- Dripfeeding to a Prototrak MX3?

[NJC]

Has anybody had any success with drip feeding from Bobcads Predator editor? I have been able to create, upload programs and cut parts with Bobcad on my Prototrak MX3, but when the program is larger than let's say 400 lines, the Prototrak comes up with an error. I've been told that Bobcad will drip feed and that the MX3 will accept dripfeeding but have no clue how. Also, if I'm able to drip feed the programs, is the MX3 able to perform 3d profiling?

Thanks,
Scott

Well where should I begin ? I had preditor, Also V22 and never got it to send large files, its GONE now !
with success. I had to copy & paste in V21 and send all day long.
As far as the MX3 goes I don't know the limit, might be 500 events. I have the AGE3 and its 1500 to memory. But I bought a DNC key from SWI and can send endless files.
If you go to program in/out what do you see ? With the DNC key you see the DNC option. Also with the key you can set the baud rate 2400, 4800, 9600, 11200 by running service code 37 (only if you have the DNC key from my understanding).Your question about full 3D is yes if you have the key also !
Without its 2.5 axis move only. You also want to make sure you make no moves smaller than .0002, its a limitation with the controller.
I hope this helps

sCOTT I RUN A PROTO TRAC SMX BED MILL WITH MASTERCAM X3 I HAD THE SAME PROBLEM BUT I CHANGED FILE EXE TO CAM AND AM USING A UBS STICK WHICH HOLDS THE WHOLE PROGRAM IN MEMORY, YOU JUST CAN NOT EDIT THE PROGRAM IF IT IS LARGE

Robert,

We wish we had your newer machine, the MX-3 was early
90's and the AGE-3 was later 90's. USB didn't even come out till around
mid to late 90's, our machines have the old floppy drives. I believe the
MX-2 & 3 had 720K floppies, and the AGE-2-3 had 1.44MB floppies. They are DOS based machines, yours is an XP machine, bet it's nice! I DNC through
RS232, with the key you can from the floppy but kinda useless, 1.44 MB max unless you want to break the program into segments, say per tool. Depending on
what you are doing, dictates how its done. Like I said previously only 2.5X without the DNC key on these older machines, sad but true.
True .Cam .MX2 or .MX3 and .DNC

Mark, how true is that, although SWI gave me the option of upgrading my controller to an SMX.... for $9,000.00 So, tell me some more about the DNC key I spoke them a while back and they suggested the DNC option, I guess at the time the machine was new to me and it seemed like a patch for a bigger problem. As it turns out, this might be a huge help. If I have this right, I can use Bobcad to gererate the toolpath, set up the machine to accept it in DNC form, and start the dripfeed from Bobcad and the machine will take it as fast as it can use it? What about tool changes? Will I be able to do full 3D profiling like a 3D portrait, or a 3D car or something to that degree?

Thanks for the help!

sorry I could not help , I have a Bridgeport dx32 and have the same problem with memory everything runs off a floppy, How do you like running Proto trac I have been running them since 1991 it fun teaching others how to run them

Scott,

Give this a try:

Open the Predator Editor.
Click on the DNC menu and select the Properties option.
Set everything on the left according to the manual. On the right check the Wait for CNC option, making sure the Flow is set to Software.
Click Next until you get the Finish button, then click Finish.

Then use the Send to CNC option from the DNC menu. That should help!?

Regards

yes you can send unlimited files, full 3D and has tool changes ! (you are the tool changer as you already know). I don't remember what I paid about 1000, to 1500, But I never got preditor to do it !! I had to copy and paste into V21 and send fine. Speed depend on the baud rate you set VS you feeds.

The One,
He needs the DNC key no settings in the software are going to change the controller !@!

Maybe you should have read the previous posts.

Thanks for the help, I'll contact SWI.

OK, so a buddy of mine works in a huge shop where they just so happened to have a few Prototraks, and one of them had a DNC key. He borrowed it for me, I plugged it into the machine, doesn't seem to act any differently and I don't see a spot to "recieve DNC" in the in/out programs area. Do I need software as well or just the key? BTW, I plugged it into an empty RS232 in the back of the main panel, not the pendant, is this where it goes? seems like the only spot by the way it's designed.

No software needed, did you by chance have the mill
in 2 axis mode MX2 , not booted to the MX3? Yes it does
plug into the same area that the logic cables go to, not the pendant. Thats where you send the files too. Mine
is on the left side behind the guard, when facing the machine.
