Is there anything limiting the size of a file I can upload via RS232?

[manike]

I have a 2004 VF2 with 16M upgraded memory.

I am using an xlTransfer from DNC, xlTRANSFER



to allow me to use USB memory sticks and upload files via the RS232 port.

It's working well with small files, but not with anything larger than would usually fit on a floppy...

I am wondering if it is a setting on the control?

I tried uploading a file that was 2.5m and got an error saying missing (...) and then in the alarms it said it was trying to load data as a comment?

I checked the file thoroughly, including the line it seemed to have an issue with, and couldn't see any problem.

I broke EXACTLY the same file down into smaller parts of no more than 1.34M, and it went through just fine.

The xlTransfer seems to be happy sending the larger file, but the Haas controller doesn't seem happy receiving it after it gets above a certain size.

Any thoughts?

Thanks

btw. Made my first chips with this, my first CNC, last night and it was awesome!

If your error persists, try running your file directly from the dnc, also happened to me, i can run files from dnc but not upload them into memory if they are bigger than 1.3-1.4 mb (floppy capacity).

in the older machines large files have to be run thru dnc push MDI 2 times then send the file it sucks no way to stop and change inserts

I was able to RS232 load a 3.2MB file the other day into a 1998 machine, so I know it's not there...

manike as in Simon ?

try lowering your baud rate and see if that works

Hey Luke, yeah it's me. Join up on my forum and get access to the insider group. You can see the whole build thread on my endeavours to put together my own little machine shop.

I will. I am going to experiment some tonight. I tried it on an older tool room mill at a lower baud rate and it worked. Gonna double check all of my settings and then start lowering the baud rate and see what happens.

It was just strange how smaller programs worked fine, but largers ones didn't.

I just assumed all these years you were already a machinist.

[manike]

I would never have classed myself as a machinist. A CNC programmer and an occasional operator with decent machine knowledge would be more like it.

In other news, I fixed the issue with the transfers. It was all my fault and nothing to do with the HAAS or the xlTransfer unit.

It appears that the transfer unit had to be set to "cr and lf" rather than just "lf". Not sure why it worked with small programs and not larger ones before but that "carriage return line feed", seems to have made it work with larger programs too. Certainly the file I was having issues with before went through perfectly now. Still at the highest baud rate too. Still a little slower transferring files than I would like, but I can live with it.

Just wanted to show my install for anyone else interested in one of these units.



I mounted it with the sticky backed velcro you can get from Lowes. Now I can take it off to replace the batteries if needed etc. It's nice and convenient next to the control.

Now I need to get some programming done and the files transferred over

That looks really cool and simple to use! Just don't start drip feeding a file to the machine and the batteries died....then you probably have a scrap part!

Can you run it over AC or DC power?

Also, might be best to setup the unit to use RTS/CTS like in the CNC Haas controller or use Xmodem if it has it. This is one of the best protocols to communicate at higher rates on the Haas controller. That might solve the memory size transfer issue...

[manike]

I solved the memory size transfer issue as I mentioned above.

I don't tend to drip feed files. I may need to some day, but usually I just upload them to the control. We shall see if I ever get to need a file bigger than 16mb...

You can run the unit on AC power, or leave it plugged in to charge it. They recommend taking the batteries out and plugging in the charger if you just want to use mains power.

I'm not sure what the different systems of communications are?

I ended up bringing up the settings on the HAAS control and then simply making sure they were identical on the xlTransfer, I had just missed the one part last time (and yet it sill worked with small files). I am currently running at the highest baud rate. Need to send over some more files, but so far it's looking good.
