Hello there
we just got a Fabkit MK6 CO2-Lasercutter (Rudia controller) and have a lot of fun with it. Lightburn is so cool!
But with our current setup we got a focal length about 3 mm above the workpiece. So if there is a clamp or the material is warped the nozzle collides with that thing.
I tried out the z axis enabled (no z optimization, no relative move) but it behaves strangely.
I found this thread Move Z Axis first? but i dont understand.
Could you please clarify for me if we got any wrong configuration?
I setup the material height to eg. 50 mm and did an z offset of 50 mm for two objects (squares next to each other).
The laser head moves first the z axis and then the x,y axis to draw the first square. Then it does not retract and goes to the next square on the same z height.
Is that the normal behavior described in the thread mentioned above?
We got the latest update of Lightburn. Didnt check the rudia firmware yet.
Thanks for your help and best wishes
