New EAF gives big crash in autorun

zeevink

My ASIAIR Pro Z.1.1(1074) works already two years perfectly with my EAF. (5v usb type) and ZWO 294mc pro. Focussing, autofocussing, in autorun and planmode all works perfect.

Now I bought a second telescope with a new EAF.
Because I dont use both telescopes in the same time, I use my ASIAIR Pro Z.1.1(1074) for both telescopes.

The wiring is the same but The new EAF does not work well with my ASIAIR Pro. Just focussing is OK, but when I choose autorun or plan mode, as soon as the EAF starts focussing, everything crashes !!
Both Camera’s (294mcpro and 174mm) stop working and I have to restart the ASIAIR PRO.
What’s wrong??

zeevink What does ASIAIR hint when you start autorun or plan mode?
And could you tell me how you power the ASIAIR and other devices?
Please submit the log in the ASIAIR app when the problem appears next time. thanks,

zeevink I am experiencing the same thing. While in autorun mode with a set of exposures in place the EAF is set to autofocus at the start of a new target as well as every hour. However, when starting the plan, the autofocus kicks in, completes and moves to start the first image capture in the autorun sequence the app says capturing but there is no progress bar and after the time for the exposure elapsed, I had to abort. The only approach now is to go to the target, run the autofocus (remove the at new target and every hour settings), then once focused start the outrun.

This is the power scheme. I use two 12V DC units, original for the CEM 40 and The ZWO 294mc pro
this never was a problem.
As soon as the autorun starts and EAF starts autofocus, a few messages flash very short and both camera's are off and the asiair has to be restarted.
As soon as it happens again I'll send the logfile. Question for now: Is the power scheme correct?

zeevink 12V 5A may not be enough for mount, heating, and ASIAIR, we recommend you use 12V 6A to power ASIAIR separately, then use ASIAIR to power ASI294MC Pro.

BTW, ST4 cable is unnecessary if you have connect CEM40 to ASIAIR via USB cable.

Thanks a lot!
I'll change this

I found a partially slightly corroded usb plug, connecting asiair with mount
hope this was the bad guy.
