T2 cutting Z axis

[mindstorm88]

Hi Zax, i've just added a Z axis to my engraver, it is setup and fuctionnal with T2.

The big question is : is there a way in T2 to do a multi pass cut that would move the z axis at each pass ?? (instead of adjust focus manually).

Thanks

Yes, it's the first option in the CNC Mode menu, Depth / Passes.

There's a quick guide on my website that explains it. https://t2laser.org/support/

Got a picture of the Z-Axis mechanism?

Picture of my Z axis, it is from https://www.thingiverse.com/thing:2626145 but i use the stronger remix for the base

Thanks, now for the tough question. How much deviation in the focus point do you get when moving the Z axis?

I tried this about 3 years ago and was quite disappointed. My Z was not perfectly vertical, the slide was sloppy, and the diode was a 5.5W with crappy focus to begin with. Have since designed, printed, but not tested another. Hopefully your success will provide the needed incentive to complete it.

Must say that for now slides are very  sturdy no sloppiness at all

Your design is infinitely better than my old one. I used some thick foam packing material to test. Positioned the laser such that the beam was near an edge, did a vertical plunge and opened the foam board with a knife to expose the burn path. Had to play with the heat to avoid melting the surrounding area. (No idea what the material was).
