[labnetwork] mla150 minimum sample size- seeking advice

[Joanna Strongson Bettinger]

Dear Lab Network

We have a Heidelberg mla150 in the UC Berkeley NanoLab. We currently have
the minimum sample size set to 5mm (using optical autofocus). We
occasionally have samples in the 5-6mm range that the system won't detect,
and occasionally have samples just below 5mm (around 4.9mm) that it can't
detect by definition.

We're exploring the possibility of asking Heidelberg to reduce that
software limit to 3mm or 4mm, and wanted to see other's experiences.

Have you lowered the sample size requirements, and if so, have you seen any
additional writehead crashes or other issues? Did you find any issues to be
due to user error in a shared facility, or were they just caused by
setting the limit so low?

Thanks
Joanna
