1.16.0 firmware laser issue

Snapmaker 2.0

I do some laser engraving onto a cork mat couple of days with firmware 1.10, result is fine:

Today my Luban told me to update to Luban 4.1.1, I did. And after that Luban suggest me to update my A250’s firmware, so I did as well(with firmware 1.16.0). But when I start a new engraving, the laser head working in a very high position, it float over material at least 10cm, of course it engraved nothing on my cork mat.

I did laser calibration again, after I set laser head float over material only 1mm and let A250 do it’s autofocus processing, here’s what I have:

02_issue_1.16
02_issue_1.16640×1280 225 KB

It still engraving line in a high position, of course it engraved nothing and autofocus process is fail.

I’m now rollback to firmware 1.10.0, the laser engraving works fine…

@RossCHT the latest version of firmware is 1.14.1:

So, I’m not sure where you are seeing 1.16.0. If you are seeing that in Luban, or somewhere else, you should open a ticket with support.

P.S. They did mess up some of the version numbers that are displayed, but I haven’t seen 1.16.0.
