I am trying to set my working space on lightburn so its axes will have the 0 point on left bottom corner. I believe is more handy to measure and start the work from that corner.
My limit switch is on the top right corner (see attached).
And it doesn’t matter how I change the origin, both in machine or in lightburn I can make it right. It will either engrave it on the opposite corner
, or when it works - the bottom left corner will be 700,500 point (and I find it hard to set up my work like that).
I’ve read a lot of stuff on the forum but I can find an answer.
You won’t find the answer you want. On Ruida, the origin of the workspace is where the homing switches are. You would need to physically move the homing switches to change it.
That`s what I was afraid of. It would have been great if we could change the axis value just for the working axis, without to affect the physical relation of the axis.
Well, from now on I will have to use my math skills
It’s easy in LightBurn to move things relative to that corner. Select your work, then click Arrange > Move to Lower-Left and that will put the item in the lower left corner automatically.
Click here:
Setting that control to the lower-left corner means that size and position are now relative to that corner of your selection.
Now just use the support for equations in the controls to enter the amount of difference you want, like this:
500 is my Y axis height, so if I want something 40mm from there, enter 500-40 and press enter. LightBurn calculates the result for you:
This one is a pet project of mine: LightBurn’s X & Y position, width, height, scale, and interval entry boxes now support expressions and units. What does this mean for you?
If you type 1/2in, and you’re in mm mode, it’ll turn into 12.7. If you’re in inch mode and type 1/2in, it’ll become 0.5. You can use ft, cm, in, or mm, along with normal math symbols and parenthesis (*/-+). You can combine them, so entering (1/2in + 3mm) * 2.5 + 1ft is valid. You can type 1/300in in the interval box to have it convert “300 lines per inch” into an interval for you. This should make working in mixed units easier.
Over the next release or two I’ll be replacing other number boxes with the new equation entry box, but it’ll take a bit of time.
