I recently tried MM2 gamma but it somehow caused a global issue on the PC
that now affects the MM2 beta that was working well.
I now have a preview window that flashes, whereby it looks like the
application is closing and reopening the window each time. I can just about
make out the "Preparing to display" text each time.
Also, I have regenerated a misc camera bug that sporadically causes a
capture error and stops the sequence. This was fixed by finding the right
DCAM for my slightly older OCRA-ER cameras, and setting the triggering to
software. I don't really want to uninstall - reinstall DCAM drivers over and
over again unless I have to.
Has anybody seen these kind of issues in their MM2 gamma adventures?
Hi again all.
Nico, you're absolutely correct, this needs more meat on the bones to be of
I went for a complete clean and start fresh:
- all DCAM drivers
- all micro-manager software and user folders
I then scanned C drive for anything named micro-manager and deleted those
folders. I also updated CCleaner and cleaned system and registry
I then restarted the OS, updated the OS, and then restarted the OS again.
I then installed DCAM-API for Windows (15.10.4787), restarted both 1394
cameras and restarted the OS again, followed by installing
MMSetup_64bit_2.0.0-gamma1_20180801.exe 01-Aug-2018 20:02
Note, following this the flashing live window issue was gone, but following
a few moments of a MDA the camea read buffer error came back:
Error: Acquistion failed.
java.lang.Exception: Camera image buffer read failed.
I recall in the past* having to reduce the buffer size to get longer
acquisitions before errors on a couple of DCAM versions (those versions had
an inverse proportionality bug with the buffer size; I found a version after
that which worked). I get lost with all the DCAM versions I've tried**.
Here are a list of a few I have in my download folder, and I don't recall
exactly which ones I've tried:
18.5.5504 - this one I've yet to try - I'll give it a go next
Note, I've also installed the HotFix Windows6.1-KB2524249-v2-x64
I've also tried numerous combinations of 1394 connections. Using 2x PCI or
1x PCI and the MB connection etc etc.
I'm a little lost, and I hope there's a little red flag in all of that
hiding away that can help.
Thanks in advance for your time.
* I debugged this issue a few years back and it was ok for a couple of
years. Either a Win OS thing or installing gamma changed things.
** DCAM-API can no longer be searched be changing the ftp web address which
makes me sad... Does anybody have a repository of older versions?
