[micro-manager-general] Zeiss XY calibration issue

[Martin <mcm...@ne...>]

MM team:
 I am having a stage calibration issue with my Zeiss XY stage, driven by a MCU-28. When I tell MM to move the stage by 100µm the display tells me it's moving the right distance, but the stage actually moves by about 130µm, so there seems to be a mismatch (I measured the movement with a calibrated grid). If I use the Zeiss MTB program to move the stage it moves exactly 100µm. I started to noticed this when I tried to do tiling and there were large gaps between the images.
 Any ideas on how to fix this?
Thanks,
 Martin
