The issue is the software states it supports cnc machines which is false as we need to clear the height of the material during travel moves , we need a new feature just 1 , go to start height before travel as a button option , this would literally make cnc routers work as intended because at the moment im just breaking my machine hitting into parts during offset fills and certain lines
What we need: * Add a “Z-Safe Travel Height” Option
Before any non-cutting move (G0), lift Z to a safe height, then move, then lower Z back down.
Auto-Raise Z After Each Cut Pass
After completing a cut, LightBurn should have an option to return to the set Z height before moving.
Fix “Offset Fill” Behavior in CNC Mode
Offset Fill should recognize that travel moves shouldn’t be at cutting depth in CNC mode.
Then they need to make that clear, or better yet remove the cnc machine option in light burn, already paid 146$ for this software to do what in reality if millmage is coming?
I think you misunderstand that Lightburn is not a CNC program, it is a laser program that can allow CNC based machines to use a laser.
The CNC enable only applies a work offset to allow CNC to work in a positive workspace that Lightburn needs as opposed to the negative workspace that most cnc’s run in.
I have used my 3d printer as a cnc , cricut , engraver but yet i go to cnc and even light burn says cnc machine with 0 logical reason , and i have created my own stuff using those exact things,
The issue is they are all 1 and the same and can all follow using relative changes to the coding which i am asking for 1 change which is a joke when they made a entire laser program , they can simply make the coding choose regular or cnc logic and cnc logic states specifically that starting position for Z should be used during travel moves avoiding any material previously cut into ,vs yes a laser can shut the laser off and move along any fixed positions even during cutting its 1 change to make it work
Whats funny is its too late … using another software now that can generate laser , cnc , 3d printing , cricut and all now , you guys left me no choice but to come up with some other way to generate the gcode required for z hop and z adjustments i just modified the gcode
This is not necessarily true. The post was for his laser use, not the CNC mill.
I laser engrave wooden serving boards for a customer that have a recessed section. Zaxis control would be nice for dealing with that recess to obtain a proper focus point.
Lightburn was a 2D program, then manufacturers started bolting lasers on CNC machines to create All-in-One products for sale. Lightburn has tried to accommodate these creations by adding Zaxis control to some degree. However, Lightburn is a laser control program (light burn, get it?).
I had a CNC mill with laser option. It was irritating having to switch back and forth. I eventually bought a dedicated laser and made my CNC machine mill-only. I am very glad I did this.
Sorry for that , 1. Was trying to get attention for this issue 2. I had a user point me in the right direction already 3. Also a recessed section in wood with a laser would be useful not to mention cnc uses that same method to drill into a object
