I’m new to laser engraving and new to lightburn and am looking for some advice/help if possible please.
I feel that i am up to speed with everything that i need to know to get started, however, no matter how hard i try, i cannot get the real position of the laser to match that of the workspace shown in Lightburn.
I will try my best to provide as much information as i possibly can as to what i have (kit) and things i’ve done so far, but any help will be greatly received and appreciated. thank you in advance to anyone kind enough to help.
Sainsmart 3018 PROver - with 3040 extension kit and 5.5w diode laser installed.
Machine has homing switches and homing is completed automatically.
Steps already completed:
Lightburn Set up Wizard:
Set dimensions to (x axis) 300mm (y axis) 320mm.
Set origin to rear left (where the machine auto homes to)
Turned on “Auto home your laser on startup”
Start from: Absolute co-ords
When starting a job, the laser moves to a completely different part of the workspace to where the image is on the lightburn software workspace. NOTE: The dimensions of whatever i am trying to engrave appear to be exactly correct when i start the job, however it is always in the wrong place on the machine.
The thing that has underlined the issue for me is when i home the machine, and then use the “Set laser position by clicking on the page” - I click on the dead centre of the page in lightburn but for some reason, the laser goes off to a completely different position on the right hand side of the workspace. Please see below link to a video of exactly what the machine is doing showing the position where the laser rests in relation to where i click on the workspace.
The position co-ordinates look right for the position of the laser once it comes to rest - albeit out of place.
I will take a screenshot of them when i’m home later on today, along with the $$ settings for review.
I have been through the article that you shared here, however nothing seems to have any affect.
Thank you for taking the time to try and help, really appreciated.
