Q. When I install dnc4U
I get a "There are system files that are out of
date on your system"
|
 |
|
A. You will probably be
using Windows 95 or 98. Follow the instructions on screen,
click any OK button, and your computer will re-boot. You will
see "updating system files" while your windows system
is loading. When Windows has loaded, re-run the dnc4U setup
again, these files have then been updated.
|
|
|
Q. When I install dnc4U
I get a "failed to register LEOCX32.OCX or LEDIT32.DLL".
|
|
|
A. You will probably be
using Windows 95 or 98. Press the "Ignore" button
and carry on with the installation. You will have the file
"mfc42.dll" missing. Update by downloading from
http://www.pronc.com/ms32.zip
Then unzip the files contained in this zip file into your
c:\windows\system folder. If you are asked to overwrite any
files only do so if they are a later date.

|
Q. When I run dnc4U I get
a "There Are Some Files That You Need That Are Not
On Your Computer".
|
|
|
A. You will probably be
using Windows 95 or 98. You will have the file "mfc42.dll"
missing. Update by downloading from http://www.pronc.com/ms32.zip
Then unzip the files contained in this zip file into your
c:\windows\system folder. If you are asked to overwrite any
files only do so if they are a later date. The next time you
run dnc4U these files will automatically register for you.

|
|
Q. Will dnc4U work with
my CNC?
|
|
|
A. This is one of the most
commonly asked questions. All we can say is that if your CNC
supports the RS232 protocol, then yes it will. We even supply
a list of predefined CNC templates to get you started for
many popular machines. We do not support exotic proprietory
protocols that are outside the scope of RS232, such as LSV2,
Fidia etc.
|
|
|
Q. What computer access
rights should I give?
|
|
|
A. dnc4U needs to be able
to create temporary files and be able to write to your system
registry. If it can't it will lock you out saying its expired.
If you get this, then you should do the standard thing of
giving users full access and then gradually tighten things
up. For typical use, a standard "power user" would
be just perfect, they have Modify, Read/Execute, Read and
Write properties.
|
|
|
Q. Do I need any specific
hardware to use dnc4U?
|
|
|
A. Depends. If you are
using a PC computer or a laptop that has a free com-port in
the back then no you dont need anything extra. If you are
using a newer laptop, then the odds are that you may have
a USB port only, in which case you need a USB to Serial cable
convertor, they are cheap only about $30
|
|
|
Q. Can I send and receive
to more than one CNC machine at a time?
|
|
|
A. Yes you can run up to
64 CNC machines at once, simultaneously, all you need do is
load dnc4U as many times as you need it, because you can run
up to 64 "instances" of dnc4U at the same time.
You do however, need a free communication port for each CNC
transmission. You can get multi-port serial cards, we really
like MOXA
we've used them for years and they are really easy to setup.
|
|
|
Q. How much is all this
going to cost me ?
|
|
|
A. You can see our latest
price list click
here.. We give great discounts for multiple purchases,
and once you have bought there are no upgrade costs, ever.
|
|
|
Q. Does dnc4U support Heidenhain
Blockwise for drip feeding large files ?
|
|
|
A. Yes.
|
|
|
Q. Does dnc4U support Haas
Xmodem for drip-feeding large files?
|
|
|
A. Yes.
|
|
|
Q. I try and run the help
file but it does not work.
|
|
|
A. We use compiled help
files with the extension CHM. To run these you need Microsoft's
Internet Explorer 4 or above and may need any one of a myriad
patches and fixes from the Microsoft website. Most probably
this is because you are still using an old version of Win95.
The files necessary to read CHM files began with Win98. To
download a helpfile that can be read in any browser, even
Win95, click
here... Read instructions contained in the downloaded
help.zip file
|
|
|
Q. I receive files from
my CNC and after a while the data is garbage then OK then
garbage again.
|
|
|
A. You need to either turn
off your communication port receive FIFO buffer or reduce
the receive value to its smallest level. You access these
by going into Windows Control Panel, Device Manager, LPT &
Com Ports. Select your com port and click the advanced tab.
Then turn off the FIFO option. You may need to do this for
each of your com ports. Also tweak the size of the receive
buffer inside dnc4U, this can affect older computers.
|
|
|
Q. I try and send or receive
a file and all I see are XXXXXX.
|
|
|
A. dnc4U has expired. To
purchase we need your computer software code. You get this
by clicking the register menu and entering this info onto
our webpage.
|
|
|
Q. I've purchased dnc4U
but I haven't received anything yet.
|
|
|
A. We do not automatically
generate your unlock information, each one is done specifically
for a customer. There may be a delay of a few hours, but it
will never be more than 12 hours. If you have an email address
from an ISP like AOL or maybe a free-account, then we have
recently noticed their e-mail filters are actually blocking
e-mails coming through, and customers assume that we have
not sent anything, but we always do!. We now send the information
as a URL within the e-mail rather than an attachment, as anti-virus
and firewalls may block those with attachments. Just click
the hyperlink and save the unlock file to your desktop- then
follow the easy to use instructions in the e-mail.
|
|
|
Q. After I receive the
unlock code it does not register.
|
|
|
A. Please follow the instructions
in our e-mail that we send you after purchase. You have to
do it in a specific sequence. We have never had a code fail,
we are afraid it is always down to incorrect input or failure
to follow our instructions.
|
|
|
Q. I need to change computer
will the software code still work?
|
|
|
A. No it won't, however
we are happy to replace the code FOR FREE.
|
|
|
Q. dnc4U changes my system
date : Why?
|
|
|
A. We may, under certain
circumstances, change the system date to a universal
format whilst it is in demo mode. If this happens, then once
you have loaded dnc4U a couple of times and you change the
format back to your normal format, dnc4U changes it only whilst
it is running, and it swaps it back when you close it down.
Once you are registered it no longer changes the date at all,
so it is always what you want even when running.
|
|
|
Q. Do you charge an annual
maintenance fee?
|
|
|
A. No we hate that idea,
unlike other DNC software vendors we don't do it, once you
have paid for dnc4U that's it. You can download the latest
version at all times free of charge. We do not notify you
either as we don't want to send you any spam, its entirely
up to you if and when you want to upgrade. FREE LIFTIME UPGRADES
|
|
|
Q. Do you write custom
modifications to dnc4U?
|
|
|
A. If you have a specific
request for a feature and we think it would improve dnc4U
we will certainly consider it and provide the feature for
free. If its probably just applicable to you, we will also
do the modifications subject to a development fee. Ask us
!
|
|
|
Q. I want to run dnc4U
on more than one computer, can I copy dnc4U onto more than
one computer with a single license?
|
|
|
A. You need a license for
every computer you run dnc4U on. We look at it this way. If
you made 100 parts for one of your customers, would you charge
him for 1 part or for 100 parts ? However, we have price breaks
and we offer very good discounts for multiple licenses.
|
|
|
Q. Why isn't my USB to
Serial adapter working?
|
|
|
A. Since the release of
Windows XP and laptop manufactures often only installing USB
ports, users are finding that a USB to serial adapter is the
only way they have to communicate with their CNC machines.
Unfortunately many manufacturers of USB to serial adapters
are not 100% compatible and communication to their CNC machine
is either unreliable, very slow, or limited to one way transfer.
For laptops we recommend you use a PCMCIA to serial adapter,
they are far superior and often not much more expensive.
|
|
|
Q. Which languages does
dnc4U support?
|
|
|
A. dnc4U is only available
in English BUT - you can fully customize the texts, menus
and buttons into your own language
|
|
|
Q. After I purchase what
else will I get ?
|
|
|
A. dnc4U is only available
via electronic-download, so you won't receive any boxes, CD's
or printed manuals. We post you a sales receipt, you should
get this a few days after your purchase.
|
|
|
Q. I'm drip feeding large
files and it stops after a few hours with a timeout message
?
|
|
|
A. dnc4U sends data in
bursts, usually block by block, but also in constant sized
chunks. Either way it will stop if an XOFF is sent (or the
CTS goes low) and will not start again until an XON is received
(or CTS goes high). If your CNC is taking a long time to interpret
the NC code then dnc4U will timeout after 600 seconds - it
assumes that transfer has stopped because nothing has happened
for this length of time. If this happens to you, increase
the timeout to say 36000. This means dnc4U will not timeout
for 10 hours, enough time to restart drip-feeding - there
is no increase in cycle time whatever value you use (we also
recommend that you turn off the receive FIFO buffer and turn
off all power saving features such as screen savers etc)
|
|
|
Q. Its says its expired,
I have never run dnc4U before ?
|
|
|
A. If you have EVER run
dnc4U before, or any of our other software, then you are allowed
60 or 30 days depending upon the software. You cannot get
60 days for every software we do, or else you would be able
to run for almost a year ! If you have installed our dncSoftware,kwikDNC,ProNC,
ProDNC etc before, its 60 days TOTAL. More than enough to
trial any software! We often get users trying to get a free
go out of ALL our software, thats why its 60 days aggregate!
A. If you have NEVER run the software before, then
you do not have sufficient access rights and permissions to
run the software. You should log in as administrator - this
will see if that cures the problem. Then get your IT guy to
slacken up on some of the access rights. The installation
setup has a file called diagnose.exe, run this and run the
test. You need read/write access to the registry - use regedit
and set permissions for users to access the registry
|
|
|
Q. I'm drip feeding large
files do I need to do anything special ?
|
|
|
A. Not all CNC will drip-feed,
so you should consult your manual to see if it uses special
protocols. But basically drip-feeding on CNC's like Fanuc,
Haas and many Japanese and US CNC's is simply a case of handshaking
between your PC and CNC. We would always recommend that you
turn off or reduce to minimum value the receive FIFO buffer.
If you use a com port that shares an IRQ with another device
such as a mouse or modem, that this other com port is not
used. ie com1 shares an IRQ with com3 and com2 shares an IRQ
with com4. All screen saving devices and power management
devices are turned off. Some USB devices can "go to sleep"
after a while and if data is sent every 20 minutes, which
is common, then the USB may not respond either fast enough
or not at all to any XON/XOFF etc.
