EFW2 loop: bug report with new driver (july 2017)

[sferlix]

Hello

I've maybe found a bug. I was able to replicate the following situation. That's why I think it should be a bug.

Scenario: Atik 383L+ mono and EFW2 with 7 positions.
I use Maxim DL for single exposure, everything is connected and working.
I select Frame Type=Light and Filter="L Filter".
The EFW2 correctly moves to the L-Filter.

if I select 'R Filter', the EFW2 correctly moves to the desired position.
If, for some reasons, I wrongly select the (non-existing) filter no. 8, a nighmare happens:

- the EFW2 starts to rotate and does not stop, even if I disconnect everything from MaximDL
- In order to stop the indefinite rotation, I've to unplug the power cord
- when I reconnect, an error occurs while initialiting camera: AtiKEFW.Core: argument not in the interval
- I have to kill maximDL because the error itself is in loop, even if I unplug and reconnect everything.
- I waste hours trying to fix the problm.

In order to recover, I've to run in a series of restarts, ecxeptions and then, I really do not understand what make it working again...

please, help

Hello All,

I've an update.
I Removed all Atik and ASCOM drivers. Windows registry cleaned. I'm a software engineer, so I (hope to) know where I put the hands.

Reinstalled everything from scratch.
Problem persists: when - in maximDL - I select the filter no.8 (the wheel has 7 positions) and this provokes a never-ending rotations of the filter plate.

From this point on, the nightmare begins: power-on/off, usb reconnect, and so on. Only a full PC and equipment restart/disconnection solves the situation.

To be hones, Maxim is provoking the problem, it's not a true bug.
But, we coud make the driver much more robust, so that the driver refuses to search for the not-existing position when some software is asking for it.

I own 2x Atik EFW2 and 2x Atik 383L+ mono.
So, I hope the Atik suppor will enhance and make more robust the EFW2 Driver.

Best regards,
francesco

Hello

The new version of the driver fixes the issue.
