Polar 350 / LB ZiAxis

[Auggy123 (Dave Titus)]

New to laser cutting, so please go easy on me! With my Polar 350, when performing two tasks for the same design, ex. an engrave and a cut, my Z-Axis reverts up after the first task is performed correctly. When I set the correct Z-axis for both tasks, it performs the ENGRAVE correctly at the Z-Axis offset I set up, but once it starts the CUT, the Z-axis offset reverts all the way up. Any clues what I’m doing wrong would be much appreciated!

I was able to wire up the switch to a z-axis limit, set the polarity, and get it to work as expected when I press run the ‘Autofocus’ command from the panel. However, now, when I turn on the device, it autofocuses the z-axis down instead of homing the z-axis upwards. If I disable homing (via lightburn machine settings) for z-axis, the whole axis is disabled (including …

What version of LightBurn are you running? We recently made some changes to this.

Good morning - I’m running LightBurn 1.4.05, built Wed 2023-08-02. I appreciate your response, but it appears to be working now. Honestly, I’m not entirely sure, but either I stumbled across something I was doing wrong and inadvertantly corrected it, our I got the latest update and that addressed my issue. But in the end, it’s working as it should be! Thanks again!
