Hello, I have purchased a zing zuter directry from KNKUSA, I have seen
your videos in the youtube and was thinking
that the machine is worth buying.
Maybe the pre-production machines were made OK but the normal ones are crap.
I have payed to KNKUSA, 399$ for Zing and 330.52$ to ship it to my
country in Europe.
We are a computer automation company that was hoping to use Zing to
cut paper and other materials to build 3D models. However out machine
was not working when it arrived. Having payed 330.52$ shipping we re
not going to send it back, as the price is crazy.
The cutter was not even starting when we got it, the metal shavings must have been interfering with electronics so since there were not :warranty void" stickers decided to open the machine, maybe some connector got dislodged during shipping and behold what we found!
We opened the Zing removing 6 screws on the bottom, IT WAS AMAZING WHAT WE SO:
- Sharp metal shavings were everywhere, they were from screw threads
that was threaded to aluminum profiles that make Zing chassis.
Since the shavings are very small they can enter bearing cause
premature failure, can cause short circuit in electronics etc.
We used compressed air and the zing started to power up, however
- We so that Aluminum profiles that make Zing chassis are uneven
length, the machine does stand flat on table and does not cut straight
either.
- We so that Zing cutter head belt is not straight, it is noname belt
(no markings) not like in your videos on youtube.
- The cutter head motor is mounted on a not 90 degree mounting bracked.
- The cutter head motor pulled is not straight, top part of the pulley
is misaligned
- Threading quality is horrible, bolts are loose or spin endlessly
when tightened.
- The metal panels that make the sides of the zing are warped, bent,
they are made from soft metal that can easily deform.
- The 3 bad bearing on the cutter head.
- other minor defects
So believing what I read on KNK webside
"With over 30 years of experience, Accugraphics used their knowledge
to develop a new product that
incorporates the newest electronics with quieter motors, faster
speeds, higher force and the widest cutting
area of any cutter in its class."
I sent them photos and a request to send me a new Zing or to return my
money back.
The KNKUSA pretend they do not see anything wrong in the photos !!!!
The KNKUSA refuse to stand behind their products, given the fact that
this is clearly factory defect, and that this was international order
it was KNKUSA responsibility to check the Zing cutter prior to
shipping. They did not do this. They refuse to refund my account for
the price of KNKZING, or to send me a working unit.

When I noticed the problem Jan 11, 2012 I contacted [email protected]ACCugraphics.co and sent all the photos and description:
got reply only at January 24, 2012 that my email was forwarded to [email protected]ACCugraphics.co
Yes 13 days to forward an email how hilarious !!!

Hello what scraches are you blind ? And you can't read!?
My reply was:
There are two main problems:
1. Metal shavings inside zing cutter machine. They are everywhere.
even on bearing on the stepper motors. I was unable to clean them
entirely 100% so the machine can fail any time it get short circuited.
2. The metal parts are made not up to specifications, they are bent,
not at 90 degree angle, not straight etc. The whole Zing cutter is not
standing flat on a table, one of the side is higher than the other
because parts are dent ect.
The metal shavings interfered with electronics, the unit did not even
power up when I received it.
After paying nearly the same cost as the machine itself for shipping I
expected you to check the machine prior to shipping because I can't
send it back due to high cost.
I need you to:
1. remove the back cover on any other ZING machine by removing 6
screws and plastic sides and make photos like the ones in my PDF
claim.
I would like to see sharp and in good lighting these photos:
1. Is there any metal dust after threading
2. How does the threading quality looks like (photograph threads like in my PFD)
3. How does the belt look like mine is noname (no markings, not
straight belt). On youtube videos I see belt on the zing made by suma
brand, so mine is a noname why???
4. Put a metal straight edge on the metal sides that hold plastic
parts of the machine like in my photos are they straight?
5. The motor that holds the belt is in metal 90 degree part that is
actually not 90 degree, so I would like you to check this with a
square tool on your machine.
There are no scratches, there is metal dust (shavings) inside! left
after threading in the factory the bolt holes in aluminum profiles
that make the chassis of the zing. This dust interferes with
electronics (short circuit), can get inside bearings of the motors
etc.
Therefore on our Zing there are no good parts ! We cleaned most of the
shavings but they are very small and it seems they found a way into
the motors too.
> Maybe customs agents took the machine out and caused the scratches.
No the machine was packed inside a bad that was not opened.

If your machine that you check and send me photos of is indeed good we
would like you to ship us new working Zing at your expense, you can
specify low price like 20$ so we would not have to pay customs taxes
again.
1. clean
2. and up to specifications (no bend parts, 90 degree parts are really
90 degree)
3. edges are not sharp
4. the length of the 3 aluminum profiles that make chassis of the zing
is the same length
(easy way to check: take 2 metal rulers 30cm each, take some
doublesided sticky tape and place one ruler on the zing, another ruler
on another size of the zing, use the double sided tape to stick the
rulers together. Now move the sticked rulers inside the machine, the
distance should be the same on the inside of the zing)
5. Also check the height of the cutter head, our machine had different
height one side than the other.
Otherwise if other zing machines have the same problems there is no
point in you shipping us a new Zing machine.
Feb 8, 2012 I write to [email protected]ACCugraphics.co
Hello, it's been 5 days since I got a reply from you.
Did you make photos, check quality of other Zing machines as I requested?
I would like to see the photos if the quality of other machines is OK?
Will KNKUSA replace my Zing machine with working one?
Else will KNKUSA give me my money back?

Shielded from metal dust that should not be there? Do you see any shielding? Are you plaing dumb or ....?
Since KNKUSA does not respond to this problem I contacted their distributors to ask do they know what crap do they sell:
[email protected]SkatKatz.com.au
createncraft.com
Both of them did not reply but instead forward my email to chad at [email protected]
Chad writes (or should I say is lying):
>We have now sent multiple Emails to try and come to an arrangement for you and >your zing.
>We have not received an answer. At this point,
>I'll gladly take any suggestions in regards to replacing / refunding you for your >machine.
I replied by simply writing:
Hello did you get my email?
You tell me you do no receive my emails when instead you do not reply !
So this is broken telephone or what? The comany KNKUSA is A SCAM!!!!
I wonder how their KNK MAXX 24" for 1,899.00 is selling, you can get a Roland 24 GX for that price come on peopple
do not trust your money to these lyers.
