why not post a price list

why not post a price list

Yeah, I second that.


Konstantin.

Better pictures, more info and something other than a hotmail address would go a long way.

I removed the link

Maybe we could use our Chinese Stepper Controls on our Vacuum Oil Purifier.(chair)

How much is it?

Yeah, I second that.


Konstantin.

as you know always price related closely with quantity, so it's hard to post the price in the board, however our price is half to U.S. relative driver. But if I claim it publicly, trust many U.S. manufacture may complaint to us.

what do you think?

a link to the chinese page: http://www.autocontrol.com.cn/cp/showcenter.asp?id=635
Even if one does not read chinese it feels better to request information in the mailfield at the bottom of the page. Hotmail feels like a sure way to get spamed.:withstupi :withstupi

the link is not the original link, actually it's a distributor.

currently the english website still under construction, trust we can show it in a short future!:)

Why do you care about complains from the competence?, Are you afraid they are going to lower their prices?.

If your claims are true, then you have nothing to be afraid of, the quality of your driver will speak for itself. But, in order for us to fairly evaluate them we need a sample so we can do a few tests.

Okay, if qty is an issue then lets go with how much is a single unit? and how much for 10 units?

That should be enough to satisfy most users of this list, I don't know how many of us would need to purchase in bulk since a lot of us are hobbyists.

thanks.

agree with evena4! show your price kelvin_au,don't just pinpoint other.

Here is a US address for them with PDFs. No prices.

hello sir,

Please check your private message:)

hello everyone,

thank you for your comments above, anyway, it's still not a very time to post the price here. I've send message to your mailbox for the price.

thank you

I think it is rather awkward that you are so protective about giving out the price. I've never seen a retailer literally refuse to announce their price in public. Figuring the public is your customer, you might consider it :).

Please PM me also.

Thank you

hello sir,

thank you for your comments!

Yes, I do think everyone here in the bbs might be my customer, and I serve everyone with special offer one by one!

Anyway, perhaps when our driver find popular sales in the market one day in the future, we consider to post the price in our website.

thank you

Okay, Kevin_Au, I have received your current price list and I beleive the prices are pretty good based on the specs I can figure out for the driver unit.

I do not understand why you can not post the prices to our forum for all to see. If it is because you are an OEM supplier to other manufacturers and by some contract agreement you are not allowed to sell them direct to the public for less than contracted price with OEM's or something, let us know. If you are simply afraid to put a price out there for the masses in fear that your prices may ultimately wind up too low to sustain your business then put them out as an "Introductory Price" so that we know it is subject to change. By the way, this usually prompts undecided people like myself to act before the prices change, that is why it is nice to see the current prices at a glance and not feel like we are all getting some "special" 1 to 1 offer which may differ from person to person.

This BBS / Forum is based on a community of sharing and pretty straight-forward Questions/Answers. We do not like to feel that someone with a business to promote is operating in a secretive manner.

I like your prices, if you are a sales rep for your company, talk to your boss and see if you can post a "current price list" it doesn't have to be forever, can be for a limited time. If you want to get business from us you need to meet us more than halfway and providing a good feel to the sales process would certainly help.

What I need from you:
I am thinking about your current prices and also need to know shipping to the US for say 3 units. Or if you have a US distributor in place already.

-Thanks

I dont' know if you've got a better price than the one I've got, but I don't find it cheap for an unipolar drive. Maybe I am wrong....

Well said Evena4!

I was under the impression that the price he quoted me was for the Q2HB68M series which would include either the Unipolar or Bi-polar models as shown on the previously listed distributor site:

http://www.sei-automation.com/drivers.html

I could be wrong, but then again a simple price sheet with exact model# not just the series would do the trick.

Thanks for the heads up though :confused:

This is typical of chineese companies. I have stuff quoted from the chineese from time to time and they always try to give you a soft price (ballpark) and you have to chew on them to get it down.

They always try to get going US rates, which really trips me out because if I wanted to pay US prices I would buy it here!

Kevin,

Hey, come on now. "But if I claim it publicly, trust many U.S. manufacture may complaint to us." That is a load of BS and you know it; what do you care if someone complains? Nobody can believe that reason.

Tune your sales pitch a little; your audience is not that stupid and you should have a little more respect for them. If you want to bargin for the price, just say so. Don't treat customers like idiots and offer reasons only an idiot would believe.

dear evena4,

thank you very much for your sincere comments:)

you're right the price is the same for unipolar and bipolar drivers, actually we sell bipolar mainly to overseas customers.

for the comparable driver in U.S. the unit price must be USD140 or USD150 for sample order, but we can offer at USD80.00 for the sample order (lowest :) ) excl. shipping cost of course, but it is still nearly half of the u.s. price, and with batch order, the price will be even lower.

By far in U.S. market there are few chinese motion products perhaps because most mechanisim do not believe the quality and performance, in some extent it's true. but when you test one sample, the driver convince itself and you'll find chinese made product can be ok too:) so currently the essence is that the opportunity to test the sample performance, that's way we can offer so low for the sample, which is the necessary process for batch order in the future.

someday in the future if your guys find many china made controller everywhere in U.S., that's the day U.S. manufactures united to appling to excute the anti-dumping issues with government, the industry must be a mass and it's a serious problem and so, we're still hesitate to the post the price publically formly.

BTW, the shipping cost to US for 3 samples is USD38 by Speed Post door to door service.

best regards,

Kevin

I dont' know if you've got a better price than the one I've got, but I don't find it cheap for an unipolar drive. Maybe I am wrong....

My mistake, I received a PM from kevin_au confirming the specs and quote are for a bipolar drive.

Kevin_Au,

How do you plan to compete with, lets say, the Gecko G201, with more features, including midband resonance compensation, just a little more expensive (retail) price in low quantities.

Here is a quote from Mariss about dealer's prices:

Originally Posted by Mariss Freimanis

The drives LOOK nice, literally. But the data sheets don't give a lot of information. Perhaps the price is good, but I think people will still be willing to pay the 150 dollars for the new Gecko drive because of assured quality. Certainly quality products can come from China, but support and documentation is worth something too. Gecko drive is the perfect example because it is the most popular unit for more powerful steppers. There are many pages of information about their drives, which I am yet to find a Chinese manufacturer offer. Every specification is clearly described.
With that PDF file linked, I could not find any mention of midband resonance. Nor could I find any mention of short protection, what input voltage is necessary for step/direction, etc.
These are significant things, and I can only assume your drive does not have it. So really, 80 dollars for what the product is, is not bad. But then it is not comparable to a 150 dollar drive like that sold by Gecko. Theres obviously nothing wrong with that (we won't all spend that kind of money on drives), but it's not fair to make a claim that it is directly comparable.

One more thing,
I think that MOST people involved in this hobby, are not idiots. Of course some are still new to this all, and may not know what to look for in a stepper driver for their application. But I think that most will also ask an experienced person for help, perhaps on this forum. So my best advice is to be as open as possible. People want to know exactly what they are getting

For anything to be purchase from china it should be at 1/4 the price here.

At 1/2 the retail price (Lets say the quoted price above for a gecko 150.00usd) makes it 75.00.

Mariss gives a 87.00 for quantity of 1k which means he is still making money at that price (although at a low margin do to volume).

If the Chinese guys aren't paying all the BS we have to pay here (environment, tax licenses insurance etc...) plus the wages are so much lower over there. The price has to be allot lower.

I think the Chinese are starting to try to compete with world industry at a "fair" market value, so they can make that much more money. But what they don't realize is everyone is just buying the products for the price because the quality isn't there. (not that they can't make the quality, they just aren't)

I think in the next 5-10years the Chinese prices are going to be going way up and the dependency on their industries will have to shift elsewhere (maybe the cheap Martian labor? ;) )

dear sir,

you get the point!

frankly speaking, it's true that our driver has no midband resonance damping function. in another word, why Gecko use such technology in the driver? the final result is that there is no low speed vibration. so we can focus the main topic to the low speed vibration in the motor. even though chinese driver has no midband resonance damping technology built in the driver, but with another different technology we can make the driver works smooth in low speed situation, it's OK, regardless of what technology you take, only if we can improve, or eliminate the low speed vibration, it's OK, right?

except the midband resonance damping fuction, chinese driver really can compare with us driver in performance, following I list a brief introduction of the driver Q2HB68MG/H:

1. DIP switch resolution setting with 12 different value, range from 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100 and 200 resolution (for Q2HB68MG)

2.DIP switch resolution setting with 8 different value, range from 1, 2, 4, 8, 16, 32, 64 and 128 resolution (for Q2HB68MH)

3. Driving current is continuously adjustable from 0.5A/phase to 6A/phase.

4. Short-voltage protection, when input voltage less than DC24, LED indicator turns RED;

5. Over-voltage protection, when input voltage more than DC96V, LED indicator turns RED;

6. Coil-ground short circuit protection, protection will be activated in case of short circuit between motor coil and ground

7. Over-heat protection, when driver temperature high to 70 centigrade, driver stops work, until temperature low to 50 centigrade, driver works again

8. Automatic idle-current reduction

9. PUL/DIR & CW/CCW pulse mode selectable

10. No build-in selection inside the driver case

by the way, you're right that in documation and support, due to the language and distance, it's true we cannot comparable with local us supplier!

anyway, we're polishing the driver manual now until the english website is workable

thank you very much for your valuable words:)

Not exactly. First: midband resonance is not a low speed instability, micro-step (if that is what you are talking about) will not solve midband resonance, if anything, will make it worse.

Second: behind Midband resonance compensation there is a lot more than smooth rotation at low speed, other technology for the same result is mechanical damping, known for a long time, but even that does not solve the problem completely...

I am sure that the manufacturer of those drives can do better in both, price and features, if you want to compete against the best.

, there is no competing with a company like gecko,ive seen numerous drivers that always tend to compare themselves to gecko ,
look in the forums and all the products and see which ones have the most threads , mastercam then gecko ,and for good reason,
for a product to up and fall out of the air from nowhere and decide to start competing with the best isn t going to compete if the price isn t competitive ,competitive pricing means offering a price that will sway a buyer to take a risk rather than buying the safe competitors product , when a person is looking at buying 3 or 4 drivers +shipping ,the figures add up ,
most people aren t willing to take a risk on an unknown product when they can pay a little more for what everyone knows is the best ,
ive read a few posts in this thread that says geckos are $150
the 201 $114
looked at ebay lately , its flooded with cheap priced drivers

i am sure you have a nice product and it sounds quite interesting but you can be dealing with a tough crowd here ,and to break into this market your going to need to decide if you can afford to make your product available in a way that people would want to test it without too much of a financial risk ,other than that your market will stay in China

Well said dertsap.


Kevin au,

dear sir,

we don't want to compete with Gecko, but phantomcow2 mentioned Gecko's with mid-band resonance damping and I have to say something abuot it. actually no comparision between two different drivers with two different technology.

By far Gecko is the best for you because you have not touched new drivers.

As far as I know, many U.S. mechanisim used 5056 and 8078 from Kelling, both 5056 and 8078 comes from China, if you used these two drivers, perhaps you will not say Gecko is the best in performance and price.

our driver comes from China also, so we do well know that 5056 and 8078 and our drivers not bad than such two.

Anyway, even though I say many many words here, you have no idea about our driver because you did not feel the performance.

dear sir,


Anyway, even though I say many many words here, you have no idea about our driver because you did not feel the performance.


you by far under estimate the people you are talking to ,the whole world knows that China is flooding the market with cheap priced products ,

many of the forum members have lost their jobs or companies because everything is being done in China for a fraction of the price ,
which means you are being supplied the drivers for a mear fraction of the price your trying to sell them to us ,
don t try to fool me either some of my friends are importers of Chinese products
why would we want to take a risk on a product nobody has heard of when it is near the price of the best driver on the market , there doesn t appear to be a warranty offered and you still don t have even have a website up , how can you expect anyone to send money to an unknown company which is over seas ,
tell you what ,
i have a new 40" sony plasma tv i bought at well below cost because i work in the factory ,i bough two freight loads , brand new in the box , i can sell it to you for $500 US i will even provide free shipping to anywhere in the world ,
give me a day or two to get my website up and running ,and in the meantime you can pm me and i will tell you where to send your money to , please cash only


don t get me too far wrong , your driver would be graciously welcomed but you need to start somewhere and you asking a lot for something that noone ever heard of
i just think your going about it all wrong

Kevin Au,

Could you possibly have one of your drivers on display, working, at the next CNC Convention this summer in Illinois so we can feel the performance?
