Laser focus screen

Official

The Galvo / Fiber mode of earlier UPAN on the Z axis of a laser. Each lens keeps its distance to the workpiece at focus. Enter the thickness of the workpiece, press “To the work position”, and the head stands so the focus lands on the new surface. Fine-tune in steps of 0.05 mm and save the result back to the lens.

Change with the agent API

The agent opens with this preset's code and your values already in the message: add what you want to change.

Install

Install codeP-7LZF

On the device's control page: enter P-7LZF.
Without internet: download the file and drop it on the control page.
With an agent: ask it to install preset P-7LZF.

Not final: installing by code needs controller firmware that is still in development. The file and the API work today.

Phrases for an agent

Add lens F330 at 360 mm.
The workpiece is 4 mm thick now.
