Re: MM2 gamma and Zeiss

Hi irina (and others),

Please note that I am replying to the micro-manager mailing list as well
as your personal email address.  In general, it is so much better to
post these kind of questions on the MM mailing list, because:
- Others may know the answer
- Others can share the time commitment to help
- My answers will become publicly searchable, so that people with the
same question can find the answer.

There is a commit in the svn repository that reads:

r16613 | nico | 2018-01-31 09:46:49 -0800 (Wed, 31 Jan 2018) | 2 lines

ZeissCAN29: Support Zeiss Definite Focus 2 stabilizing position.
Pull Request 609 by Tineke Lenstra.  This commit changes the ZeissCAN29
device adapter by adding a property DefiniteFocusVersion (either 1 or 2)
and using its value while fosussing (using the StabilizeThisPosition
command) to determine the amount of data to read from the response.

This code should be in all current builds (1.4, 2.0-beta, 2.0-gamma) of
Micro-Manager.  I don't know how well it works, others can comment.  It
never hurts to try it out (and I advice to use 2.0-gamma for your
testing). Please do reports problems to the mailing list.

Re: MM2 gamma and Zeiss

This post was updated on .
I upgraded from MM2.0.0 beta 3 20160826 to MM2.0.0 gamma 1 20200119. Nice
changes in many places!
Unfortunately, I had to roll back to  2.0.0 beta 3 20160826, since Zeiss
Definite Focus (first one) did not work with 2.0.0 gamma 1 20200119. It
said "Error occurred in device ZeissDefiniteFocus: wait timed out after
Note that Definite Focus worked fine through the Zeiss interface. It is thus
related to the MM2.0.0 gamma 1 20200119 code.
I attach the corresponding CoreLog if it can be of any help.
