Typically those setups are independent of any software Z axis control. The up/down motion of the laser head is controlled directly via the distance sensor. So, yes, it should work just fine with LightBurn in that LightBurn won’t care about or interfere with that feature.
Whether or not that machine actually has a Z axis that can be software controlled by LightBurn is a different story that depends on the machine.
That is an interesting concept. Never seen it before.
Is this an actual product or is this a proof of concept? I could not find it on their website.
At the end of the video you can see that they lift the cardboard and the Z-axis moves up, following the height of the cardboard. To me it looks like a closed loop system which was put on the machine without using the Ruida controller.
I might be mistaken though. This is of course highly dependent of speed. I am not sure if they choose to limit the operating speed for the closed loop system to function?
Thank you for the responses. I’m looking at a 1300 x 900 mm working area with a Reci 100 watt W4 laser tube. I want to be able to engrave and cut wood and acrylic. The ‘z’ axis appears to be a cool additional feature. It removes the need for a rotary device to some extent.
The controller they have suggested is the Ruida RD6332M
So I guess from what people are saying above Lightburn will work as expected and the Ruida control system will manage the auto-focus up/down system.
I have also asked for Hybrid Drive rather than conventional stepper motors - because I saw a recommendation on YouTube. Does anyone have any thoughts on this upgrade?
