If you were a programmer supporting 10,000 lines of code, you would likely not suggest this.
I donāt want to tear down a standard discussion here.
I work in the metal industry (machining) we sometimes have parts on the machines that sometimes run for days and everything with absolute coordinates in the program.
These programs are of course also created with cam systems.
Are they aliens or gods who provide support for such programs?
So itās possible and you should always take customer suggestions seriously, otherwise someone else will end up doing it.
But thatās just a side note.
I now know that it or what I imagined doesnāt work in my current configuration.
Thanks to all.
Greetings Jan
@MikeyH is a community member. Heās been a great contributor in the time heās been here but he doesnāt speak on behalf of LightBurn.
We do take customer suggestions seriously. I am also participating in the internal discussion on this topic with four developers.
I would like to know more about the controller or Terminal Adapter. After reviewing the Estlcam changelog for Version 11 I see they have added support for Ramps Hardware and KineticNC.
Jan,
Lightburn always does this. They even have a website to suggest or vote for changes. Obviously, more votes often gets more attention.
To be honest, your one-off custom machine and controller is the first I have encountered in many years on dealing with CNC controls. This not to say yours is unique, but as I stated earlier, a CNC controller with at least GRBL or LinuxCNC features was not on my radar.
Yeah, I am just another laser owner using Lightburn. Unfortunately, I have a tendency to voice my opinions, and try to indicate when I do so. I am not privy to what is happening there, but I fully support whatever they do.
What are you trying to tell me? Iām just a hobbyist and unfortunately I canāt give you any great information about the Estlcam control board or terminal adapter. You can find information about how it works and other things on the estlcam website or perhaps contact Mr. Christian KnĆ¼ll, who is the developer of estlcam.
All good 
.
Mr. Christian KnĆ¼ll developed the controls and the cam. I think even just in his free time. The board costs around ā¬60, the Estlcam software is free but you can also buy it for around ā¬50, then some things will probably go faster or something.
Arenāt all small 3018 CNCs run by grbl controllers? I though so. I have a cheap version of those and it runs grbl 1.1f or something. I have been thinking that most CNCs also run grbl controllers (grbl was written for CNC originally, not lasers).
I was talking about his limited-feature controller. Even some controllers not Arduino based are running GRBL.
If itās only the Z axis that switches to G91 you could write a post-processing script to convert to absolute moves. You could do it as well even if x and y and z do it.
Basically readline,
search for g91
rewite as commented out (usefull for troubleshooting when working on code)
if x move then xabos=xabos+xcurrentmoveinc
same for Y
same for Z
write line g90 xabos, yabos, zabos
Write to new filename
Perl or Python would be the ideal tool to creat this type of script.
