Efw problem

johnno

Have the 1600 mc cool and the 7 position EFW.

Did all the installation steps properly, but

Filter wheel starts turning and does not stop, as soon as USB connection is made. Does not matter if using USB 3 direct from PC , USB 2 hub, or USB 2 hub on camera

Have installed Ascom 6.2 and asi camera driver and Efw driver.

EFW does this on PC running Win 10... also on Dell xps 502 laptop running Win 7.... also on Dell xps running Win 10. Have been installing and uninstalling all software for two days now and now SG Pro has packed up.

Am now ready to dump everything into the bin, unless someone has a solution.

HEEELP !!!

Regards

Johnno

Thanks-- tried that. Same results.

Wheel just goes round and round. Pauses at random places, and then continues on it's rounds.

Tried connecting directly to Laptop USB port. Tried via the camera USB hub. Tried different cables .

EFW no good and needs to be replaced.

Tried same on PC ..

When we did a diagnostic on the 7 position filter wheel.

When the filter wheel is in position 1 and you plug in the usb cable the filter wheel starts and works perfectly.

When the filter wheel is in any other position and you plug in the usb cable the filter wheel continues to rotate all the time and stops at random places in-between two filters and does not initialize.

There for before unplugging the filter wheel a person must first return to position 1 so that it will work the next time.

Thanks to Neil of Telescope Shop for your on site assistance today. At least on a temporary basis , the EFW can be used even though the method is a pain.

Let's hope the full solution is just a firmware update away.

Regards to all

Well here we are, nearly 1 month down the line and still have to make do with the "temp work around" as per my earlier post.

Whilst I am aware that ZWO are prepared to replace the Faulty EFW wheel, please realise that as long as it is in transit to or from ZWO, I will be unable to use the camera.

I would have thought that a replacement unit, or even just the circuit board ( which is really tiny) could have been sent to the South African Distributors for a swop out.

Can't help feeling somewhat dissapointed here.

I had exactly the same problem with a new EFW and ran similar diagnostics. I concluded there was a hardware fault. Vendor (First Light Optics in the UK) agreed and has replaced the unit. New unit received two days ago and works exactly as it should.

I suggest you get your unit exchanged for a working one - it will save a lot of hassle.
