Well after waiting since my order directly from ZWO a 533 MM shows up.

 

The packaging was strange. There was no padding for the camera except for the small cylindrical camera case.

 

Got home from work....Camera seems dead. Connected to a 533 MC and all fired up.

 

Could not connect the 533mm to SGP could not connect to sharp cap.

 

The 2600 MM I ordered in November 2021 is not working either.

 

I never had problems with SBIG or QSI cameras and I have owned maybe five of them.

 

I am really frustrated with the ZWO value engineering approach of cutting cost to the bone including failure to properly package a camera for international shipping.

 

What a bummer.

Who did you order them from?  Return the camera's and get a refund.

 

I have never had issues with ZWO.

People have all sorts of experiences good and bad with everything ordered from anywhere. Posts on CN don't provide enough data to know if ordering directly from China is better or worse than ordering from a retailer closer to home. Similarly I don't know if we have any substantial evidence that retail orders shipped from China to Texas (by air freight or ocean freight) are are more roughly handled than orders shipped inside the US.

 

This is the ZWO statement on cameras purchased from a dealer. "For customers who bought the camera from your local dealer, dealer is responsible for the customer service." What does that mean? When I had a failure during the warranty the retailer in the US arranged with ZWO to have the camera shipped to China via DHL prepaid. I was not charged for shipping in either direction.

 

Later ZWO posted that it has some sort of warranty/repair operation in the US. I say some sort because at least one large and well established retailer in the last week directed a customer with a warranty claim to ship the camera to them and to prepay the cost of return shipping. The retailer said it would ship the camera back to China and then when the camera was returned to the retailer by ZWO it would ship it to the customer.  This the customer was told would take a month or more.

 

California law sets forth certain requirements for consumer warranties that are problematic for some companies not just small companies in China. Here is the law (emphasis added)

 

(a) Every manufacturer of consumer goods sold in this state and for which the manufacturer has made an express warranty shall:
(1)
(A) Maintain in this state sufficient service and repair facilities reasonably close to all areas where its consumer goods are sold to carry out the terms of those warranties or designate and authorize in this state as service and repair facilities independent repair or service facilities reasonably close to all areas where its consumer goods are sold to carry out the terms of the warranties.

 

Further the law requires that,

 

“Unless the buyer agrees in writing to the contrary, the goods shall be serviced or repaired so as to conform to the applicable warranties within 30 days.” Cal. Civ. Code § 1793.2

 

It is not completely clear that all provisions of the California law  are applicable to an internet purchase from an off shore seller. But they are generally applicable to a US based retailer.

 

The laws vary by state  and enforcement might vary from county to county, but some protection is better than none and my experience has been that a dealer with whom you have a relationship can be very helpful in sorting out problems with at least some manufacturers.

According to some reports, the new models of 533 family need the 12V plugged in just to operate. The USB3 connection alone is not enough, even if you are not using cooling.

Worth a try if not already done.

Well I am not a logistical specialist, but the shipping box has no foam or bubble support to cushion the camera during the transit from China. The shipping box felt very heavy for its size.

 

This is negligence. There may be systematic errors in the cameras due to damage from shipping. This might be a root cause for being DOA. Connections becoming loose while the camera bangs around during shipping.

 

But this is a value engineering blunder. Many people do not understand value engineering. VE is cutting corners. If I was selling this camera to someone, I would have packaged it better.

 

I still need to send my 2600 back for services. Never ever had a problem like this with an SBIG or QSI. Drivers always worked, cameras always worked.

 

I am starting to wonder how well these cameras hold up over the long run.

Well sent a support ticket to ZWO.

 

Hopefully they respond correctly. I hope they do not try to get this post removed.

Hobby Astronomer,

 

   What are the symptoms of "not connecting"? Do you see any changes in the Windows Device Manager as you plug and unplug the new camera?

 

   I am wondering if the camera requires the very latest device drivers. If the VID/PID of the camera doesn't match something Windows recognizes, then it will not connect because the drivers cannot load. The VID/PID are picked up and compared to installed device drivers. An older driver may not have the info required for the connection to happen. One clue to that situation is that the Device Manager will see something connect but cannot load a driver because it doesn't match any known to the system.

 

   So, it might be good to download the very latest set of all drivers and install those just to make sure. Make sure to install all of the drivers, not just select ones. After doing do, if you still see no indications that the Windows Device Manager saw something, then the camera could indeed be DOA.

 

 

John

Did connecting the 12V power help?

Apparently the new boards will bot be recognised at all unless the 12V power is connected. USB3 connection alone is not adequate.

Thanks for helping. I did use a ZWO power adapter. The same one that worked with the ZWO 533 MC.

Well, was worth a shot!

Hope it gets sorted out.

That sucks, my ZWO ASI533mm pro came from FLO via DHL Express and it was extremely well packaged with air bags and bubble wrap. FLO is stupid fast in international shipping as I got mine in two days form order. I am building a dark library right this moment. Hope you get things sorted out.

I got mine yesterday, directly from ZWO via UPS. Good packaging, no problems. Dark library built, ready to start imaging tonight (hope this post doesn't bring clouds...).

 

Sorry for your problems.

UPDATE 

 

Tonight, when setting up my rig, I did not initially connect the 12VDC power. I was unable to connect to the ASI533MM or any devices connected through its hub until 12VDC power was connected.

 

This is new. All my other ZWO cameras communicate and pass USB through hub by simply connecting the USB3 cable to a computer. I normally leave the 12VDC disconnected until ready to start imaging (polar alignment done, etc.) to avoid unnecessarily running the fan. With these, I just need 12VDC connected for the TEC cooling to operate.

 

I think this is a source for confusion...

This would also apply to OPs 2600MM.

Got my 533mm direct from ZWO 2 days ago as well, connected it straight to the ASIAir Pro (with 12v power from the ASIAir), worked just fine. Came packaged exactly the same as yours. This is my 6th ZWO camera (not including guide cams), all have worked flawlessly. Given you have connection problems with another camera similar to this I'd suggest this is likely user error and not a camera problem.

I am surprised to see that packaging, but 2 of you have reported it. Mine arrives in a few days.
