Drip Feed 88HS

[zcases]

I have communication working well as far as sending and receiving programs that run from the control, but keep getting a parity error trying to drip feed. I wonder if someone would be able to send a simple program to help me find what I am leaving out or mistakenly leaving in? I have taken out the "O", and the "%"......but still consistently get the parity error.....any ideas?

Thanks in advance

I'll venture to guess your problem is lack of proper flow-control handling in your PC serial port driver. Today, you're probably using a USB serial adapter, and many of those don't do flow control sufficiently well (or work well with the PC software that is sending the file). I suffered from this until I switched to DNCv3 (now using DNCv5) from DNC Software - Made in USA What their software does that most others don't is use X-Modem protocol, for error-free transmissions -- it handles flow-control entirely within the transfer protocol, so there are no dropped characters, or no parity errors (because a bad-transfer will be re-tried to be error-free). On the 88HS control, you just use the DNCX command instead of DNC.

Hi David, I am using the One-CNC DNC LInk, it handles hardware and software handshake, has X Modem settings, and I am using a real serial port on an older desktop PC.

Is anyone else here using the OneCNC DNC LInk software?
How about a simple program so I can compare, would anyone have something even as simple as....say....doesnt matter,... drill a hole or something.

I will try the DNCX command but I thought in the manual it stated that DNC command after a certain version board (1400-?) the DNC command was effectively doing the same "stuff" as the DNCX (I have the -4 which as I recall was after this effectivity date). It will be interesting to see what happens.

WIll keep you posted and thanks again............

I use communication from smartcam been using it sence the dos version, never had a problem on any of my machines or fadals, we have run over 50 meg surfacing programs in them.

I send mine over just like I send a regualr program over. nothing special.
cd,9
ta,1
forgot the baud rate for cd,9 however that one worked best for me.
I believe x-on xoff needs to be on and whatch your time out times.
if I remember I can look for the settings monday.

Oh yeah it also works fine with dos and regualr windows commmunication software. 99.99999999% of the time its your settings

[David Ferguson]

I use the OneCNC Link program for sending files to the control. It does not seem to handle DNC as it doesn't react to the software flow control (or at least doesn't do whatever is needed to interact with the USB to serial converter driver). That is exactly what I was using and ended up switching for DNC as detailed above.

[zcases]

Hmmm, thanks David.....DNC is new to me but, I wonder, since I am using the serial port directly (no USB converter) do you feel that is still a possible issue? Maybe I should see if your software has a trial period..................

THanks!

Hi Scott,

I am using One CNC to drip feed to my 4020. I send large 3D surfacing files with no issue. Here are my settings in the send settings.

COM PORT: COM 1
DATA BITS: 7
BAUD RATE: 9600
PARITY: EVEN
STOP BITS: 1
XON/XOFF BOX CHECKED
LINE DELAY: 0

I have ignore line prefix (

The start of my program looks like this:

%
O0002(PART-1104-0006-0453)
N2(INTEGRALSKINCAVITY)
N4(TRP0453-SIDE2)
N6M98P9000
N8(ROUGHFACE)
N10T2M06(2"SHELLMILL-AL)
N12S3500M3
N14G0G90G54X-9.7Y2.25
N16G43H2Z2.M08
N18Z0.3
N20G00X-9.7Y2.25Z0.3
N22G01Z0.17F35.0
N24X9.5
N26Y0.75

I use a sub program for my prep codes. This is a large 3D job that I just ran. I found the 88HS easy to set up for DNC compared to my Yasnac MX-3. Let me know if this helps.

i use TA,1 to send a program but i type in DNC instead then start it feeding from box when drip feeding.
i do use a calmotion usb/cnc box to dnc to all my fadals so i dont tie up a computer, maybe its different with your software.

[DareBee]

I have played with a lot of send softwares with my 94.
I strongly suggest getting NCFadal
Other than setting the COM up it works so simple. No typing on the control at all, somehow it tells the control to start for DNC or send by itself. Just have the command prompt flashing and go.

BTW your machine will severely starve at 9600 baud - I run 38k easily with my -4 control

[Ryanscustom]

I have had no issues with NClink(OneCNC). It set up and run easily. My Matsuura was a nightmare to set up compared to the fadal. From the menus I use memory/runprogram/DNC/begin and then send from the computer. Works great. The settings I use were from the manual I had. I will try raising the baud rate and see what happens. Thaks for the suggestion.

sounds like the cable your using.
I took a old serial mouse cable and cut mouse off, and took a old printer cable ; cut the printer end off. soldered the wires i needed to and taped it up, never had a issue with it. It's around 9 ft long. I can run 38k. 57k.115k. It depends on witch machine I'm using.
We have some machines newer that others.

I have also use a longer cable 50 ft, maxes out at 48k, every time.

with any serial connections, the shorter the better.

Also you can try the test plug, and run the test program.

I trued a lot of diffident programs, fadals software has been the best for me to send / receive programs , so quick. DNC
