K40 - Lightburn and LaserWeb different movement directions

LightBurn Software Questions
1

Hey guys,

need your help with my K40 (with Mini Gerbil Board)

Limit Switches are in the upper left.

To use Lightburn I have to set $3=3 and $23=3 to have the right direction of movement and homing to the upper left edges.

If I want use my K40 with LaserWeb I have to set $3=1 to get the right way of movement. With $3=3 the movement in the y-axis is diversed. I experimented with the $3 and $23 values to get common values, because some projects are better to work in LaserWeb and some in Lightburn.

Can I set up something in the Softwares to get a right way of direction with same $-values or do I have to setup the right values before every use in each software?

Hope I can explain my problem right. Sorry for my school-english (it is some years ago) :slightly_smiling_face:

thanks for your help

Where do you have the origin point set in LightBurn? (in Edit > Device Settings) And when you home the machine, if you type ? and hit enter (in the console) what does it report back? (that will tell you what it thinks the current position is)

got it.

set the origin point to bottom left (same as in laserweb, there you cant change it) and tried with $3 and $23 to got it to work.
Think it was $3=4 and $23=1 but it was too late yesterday to write it down :smiley:

Only problem is the offset now. My Homing point is top left and because of this lightburn has to work in the area x (0 | 320) and y (0 | -230) but if I set the y-offset to -230 (same as in laserweb) my laser is not working as I want it to do.

Working with “current position” works aswel, but skipping to absolute coordinates does not work as I want. Have to set the workspace to negative values, but I read that lightburn dows not support negative workspace values.
Have to experiment a little bit!

I don’t see why LaserWeb wouldn’t work with the home offset position applied.

I’m honestly very curious which projects work better in LaserWeb?

5

got it!
My issue was I had $10=1 … set it to $10=0 and the offset works well now!

Like I want it!! Thanks a lot!

sometimes it’s more comfortable for me to select special layers in the stack view in laserweb than in the graphic view of lightburn!

like in the screenshot as attached :slight_smile:
