Why does this software lose the positioning to do a repeat job? I will use the laser to cut the outside edges of the board on cardboard so I can put each piece of wood in the exact same spot to make it over and over. The laser starts at the Home position. I run the Cardboard cut and its perfect. I then tool the piece outside and enable the carving/cutting for the rest of it. Some times it will run the set (which is all in the same file) and it will be where it should be. After one run but sometimes even on the First run it will not stay within the location in the software, the whole thing will go up another Inch before burning so part of it is now Off the piece of wood and I just wasted another. I bought 200 4x6 pieces to make the same thing over and over but cant even get ONE to work. The software just updated, wonder if that causes this or what the deal is. I don’t get why Laser systems don’t use a systematic MM feature like both of my CNC. it makes no sense why it will work where you want it. swap out the part, enable the real work and auto FAIL.
A bit confused
lightburn is fully metric. If you re in inches you can go to Edit → change scaling to mm/min
Now either you are not using absolute coordenates, or you have a mechanical issue on your machine because if you ar always on the same coordenates from home, machine should be as precise as the frame can make it.
Software shouldnt have any impact on this.
Check If you are in current position of absolute coordenates in your laser panel
Need to clarify a bit from my original. The design is done completely in MM, I was talking about how on my CNC I know that when I am at the bottom left coordinate 0,0 and I tell it to go to 100,100 it will always go to that exact point with no change. This I am at the home position of 0,0 and the first point for the cut is at say 20,20 and cuts me out a 100mmX100mm size square foe the wood to site in the hole. I will cut the hole and it will be exactly 20,20 for the bottom left corner. I will then place the wood in the spot and my image in here will show it carving inside that square. I will start the burn with me making no changes and not moving the laser from 0,0 instead of going up to 20,20 and finding the burn area inside it will go up another 20mm and over 20mm more than the first burn therefore throwing it out of whack with where it should be on the material but not always. As for position I have tried both Current and Absolute. Absolute failed the most.
Check your “Start From” setting… it sounds like an origin problem.
Lightburn’s Absolute Coordinates have never failed me.
